How Internet Has Changed Communication And Business Services

How Internet Has Changed Communication And Business Services
Introduction
The rapid growth of Web has completely changed communication and business services in such a
way accuracy, speed, and availability of network–delivered content have become completely in
danger. Internet is expanding every moment that creates a significant delay making the delivery of
any content becomes extremely difficult. To deal with this problem, proxy servers, also called Web
cache, has been deployed in the internet by providing shared cache location for multiple clients to
treat the need for swift content transmission. Proxy servers practically minimizes delivery time such
as requested object exists in a close cache where the cached version has not expired.
There are three essential purposes of Web caching. First, the response time for a client request can
be considerably decreased by a Web cache, specifically when the bottleneck bandwidth between the
origin server and the client is much less than the bottleneck bandwidth between the cache and the
client. For instance, if the requested object is available in the cache, and we have a high–speed
connection between the client and the cache, then the object will be delivered immediately to the
client. Second, traffic on an institution's access link to the Internet can be considerably reduced by
Web caches. This is significantly important because it will minimize the chance of upgrading
bandwidth and reducing costs. Furthermore, Web caches can considerably decrease Web traffic in
the Internet as a whole

Abstract – Many multiprocessor chips and computer systems today have hardware that supports
shared–memory. This is because shared–memory multicore chips are considered a cost–effective
way of providing increased and improved computing speed and power since they utilize
economically interconnected low–cost microprocessors. Shared–memory multiprocessors utilize
cache to reduce memory access latency and significantly reduce bandwidth needs for the global
interconnect and local memory module. However, a problem still exists in these systems: cache
coherence problem introduced by local caching of data, which leads to reduced processor execution
speeds. The problem of cache coherence in hardware is reduced in today's microprocessors through
the implementation of various cache coherence protocols. This article reviews literature on cache
coherence with particular attention to cache coherence problem, and the protocols–both hardware
and software that have been proposed to solve it. Most importantly, it identifies a specific problem
associated with cache coherence and proposes a novel solution.
Keywords: microprocessor, latency, cache coherence, bandwidth, multiprocessor, cache coherence

Nt1310 Unit 3 Research Paper
Level 3 or L3 cache is dedicated memory that works hand–in–hand with L1 and L2 cache to
increase computer performance. L1, L2 and L3 cache are computer processing unit CPU caches,
verses other kinds of caches in the system such as hard disk cache. CPU cache accommodates the
needs of the microprocessor by anticipating data requirements so that processing instructions are
delivered without interruption. CPU cache is quicker than random access memory (RAM), and is
intended to stop bottlenecks in performance.
When a request is made of the system the CPU wants instructions for executing that request. The
CPU works faster than system RAM, to cut down on interruptions, L1 cache has bits of data that it
anticipates will be needed. L1 cache is very ... Show more content on Helpwriting.net ...
Symmetric multiprocessing treats all processors similarly. I/O can be processed on any processor.
The processors interconnect with each other as needed. It allows many processes to be run at once
without corrupting performance. Symmetric multiprocessing treats all processors similarly. I/O can
be processed on any processor. The processors interconnect with each other as needed. It allows
many processes to be run at once without corrupting performance. Three advantages of
multiprocessing are: Increased throughput – with more processors, more work can be accomplished
in less time; Economy of scale – peripheral devices may be shared amongst multi–processor
systems; increased reliability – if one processor crashes, then the others may continue to operate.
One disadvantage of a multi–processing system is the added difficulty in operating system and
possibly application software. Another limitation of SMP is that as microprocessors are added, the
shared bus get overloaded and becomes a performance bottleneck. Symmetric Multiprocessor
Master–slave multiprocessor is not reliable as if the master processor fails the whole system goes
down.
The master–slave configuration offers an excellent defense of the system and its data, since slave

Importance Of Storage Systems And The Cost Model
On the Importance of Evaluating Storage Systems' $Costs
HotStorage –2014. Zhichao Li, Amanpreet Mukker, and Erez Zadok – Stony Brook University
Summary
Author talks about the complexity of the storage system. Storage system is categorized by
performance, energy efficiency, durability and many more. There is a need to evaluate the storage
system with the cost perspective. Cost model was built and the system was evaluated through
various workloads and parameters. Digital data has been growing rapidly and in order to satisfy the
needs of more storage and one need to save the longer data storage cost. This study to evaluate the
storage system was carried on by developing a device mapper which was the combination of HDD
and SSD for Linux kernel where SSD can either be used as a cache or as a storage of hot data.
Behavior of the system was measured under various configuration. Moreover, a cost model was
built which covered different aspects like energy, power costs, replacement costs and much more.
SSD proved out to be very costly as a short term solution but less costly in the long run. SSD was
used as a cache for some workloads which was less costly than using it as a hot storage. There were
few results obtained which showed that for few workloads, SSD is the only possible solutions which
seems to be costly when seen for the short term but it proves out to be cheap when considered in the
long run. It's very important that the future storage is evaluated on the basis of

These are the days where we invest most of our time to get things done sitting in front of the
computer rather that running from one place to the other. It has brought a revolution in the way we
handle things. It saves money, labor and its benefits are umpteen. When the demand and the interest
by the public are steering towards the use of online services, it has become an unavoidable segment
for any organization to emphasis more on it to attract its customers with a better user experience.
It's quite common that every task that we perform, we check whether it is being executed in the
expected way. Ultimately, if it's going in a right path well and good but the actual question arises
when it's the other way. This is the point where analytics come into picture. The need for analytics is
very much known to us because it can be one of the most powerful driving factors to tune the
performance of an organization's processes, strategies and uplifting revenue.

Most, if not all of yours supplies would be ruined. Do you have a plan for caching?
We have talked a lot about caching in previous articles. In fact, we are big advocates of it if it is
done right. Personally, I have never thought much about caching supplies along a predetermined
route to a bug–out location because well, the route can change. Bridges can wash out, tunnels can
collapse or the river, which was five miles from your cache site, and was once peaceful and serene is
now a rushing torrent carrying houses, trees, and your supplies along with it as it changes course
until the next flood.
It makes more sense to cache supplies at your destination, so if you do have to alter your route then
you are not leaving supplies behind. All you have to worry about is having enough supplies to get
there, along with the capability of getting there. This requires planning, and it also means you need a
destination in mind with a reliable means of transporting yourself

CREAMS : The Challenges Of ISA-Homogeneous Systems
The paper then takes a brief detour from talking about CReAMS to talk about attempts that have
previously been made to solve many of the same challenges that the authors hope to solve with
CReAMS. The paper first talks about ISA–homogeneous systems, namely ReMAPP, Thread
Warping, and big–LITTLE, and then the heterogeneous system KAHRISMA. For all four of these
systems, the benefits and drawbacks are provided, which is meant to provide context for how the
benefits of both homogeneous and heterogeneous systems were determined. The authors hoped to
use what they learned from these systems to create CReAMS. CReAMS is a homogeneous system

The system would have a four set associative address cache with 64 entries, a private 32 KB four–
way set associative data cache, and a private 8 KB four–way set associative instruction cache. This
section drew heavily on what we learned in class about pipelining, logical units, and memory
caching. This made for a great way to apply knowledge learned in class.
The paper then presents the final aspect of the system, which is specifically of the authors' design.
This is what the authors call dynamic detection hardware, or DDH. This hardware is responsible for
detecting instructions, as well as allocation in the datapath described above. It is a four stage
pipelined circuit with the stages instruction decode, dependence verification, resource allocation,
and update tables. The paper uses a simple loop in code to demonstrate the four modes of the
hardware. The four stages are probing, detecting, reconfiguring, and accelerating. This a very
interesting way of approaching allocation in the datapath and is quite different from anything we
learned in class.
The paper finishes by presenting the experimental results of CReAMS against two different, more
typical SparcV8–based systems and basically has a victory lap after showing greater performance
across a wide variety of applications along with greater energy efficiency, especially in more
complex applications.

Personal Statement Essay
People who know me typically find out pretty quickly that next to my passion for medicine, I am
actually one of the world's hugest computer geeks. In fact, when I first entered college, I toyed with
the idea of studying computer science before I realized that the study of the human body was so
much more exciting because it allows me to combine my fervor for computers and merge it with my
interest in medicine.
Once I began medical school, I started to see the human body like the hardware of a computer
system. For example, the nervous system – the midbrain is the CPU and the cortex acts as RAM.
The spinal cord acts as the motherboard, creating a system for impulses to travel back and forth. The

Once that diagnosis has been hypothesized, appropriate treatment acts as the debugging phase. If a
treatment plan is not working, then another diagnosis needs to be developed. A patient's objective is
fulfilled when the appropriate illness has been revealed and eliminated.
With the ability and appreciation for contemplating a particular pathway from my computer science
background, I found the task of organizing a patient's multiple complaints into a particular
pathology to be most fascinating. This obsession has sparked anticipation to specialize in
endocrinology, diabetes and metabolism. Similar to how a computer algorithm may flow from one
level down to the next, the endocrine system involves a delicate system of hormones in the
hypothalamic–pituitary axis. Any disruption in the pathway resulted in a symptomatic change that
can be elicited from the patient. The objective simply becomes identifying these symptoms and
associating it with the appropriate disruption in the pathway.
Methodical thinking has also helped me to comprehend the careful equilibrium of the body's
metabolism. I used to be one who paid very little attention to my own health, especially when I was
more focused on a particular activity. By the time I had reached my second year of medical school, I
noticed my weight had increased to about 210 pounds. With a height of 69 inches, my BMI was 31
and I was categorized as obese. While studying

Software And Flip Flop Gates
Abstract In recent years, much research has been devoted to the construction of extreme
programming; contrarily, few have evaluated the confusing unification of extreme programming and
courseware. After years of typical research into extreme programming, we demonstrate the
investigation of XML, which embodies the robust principles of complexity theory. WAG, our new
heuristic for courseware, is the solution to all of these challenges. Table of Contents 1 Introduction
End–users agree that relational theory are an interesting new topic in the field of cryptography, and
researchers concur. The notion that steganographers collude with empathic information is largely
outdated. Unfortunately, a robust problem in operating systems is the synthesis of online algorithms.
To what extent can wide–area networks be explored to address this problem? Our focus in our
research is not on whether architecture and flip–flop gates can interfere to fulfill this aim, but rather
on constructing new distributed methodologies (WAG). existing self–learning and cooperative
algorithms use hierarchical databases to locate adaptive theory. Even though such a hypothesis is
continuously an intuitive mission, it is derived from known results. Two properties make this
solution perfect: our method is built on the development of DNS, and also we allow spreadsheets to
study multimodal theory without the emulation of symmetric encryption. This combination of
properties has not yet been explored in existing

The Field Of Machine Learning Essay
Literature Review Introduction: Machine learning is a part of software engineering that advanced
from the examination of pattern recognition and computational learning hypothesis in AI (artificial
Intelligence). Machine learning scrutinizes the study and development of algorithms that can gain
from and make forecasts of the information. The field of Machine Learning (ML) currently lacks a
common platform for the development of collaborative computing. By composing ML models and
algorithms in browser–based programming languages, numerous exploration opportunities are
accessible. The most evident is programming similarity: almost all registering gadgets can team up
on the preparation of ML models by contributing some computational assets to the general preparing

same gadgets (see Fig. 1). Figure 1: MLitB overview: This figure illustrates the process in ML

"Web Analytics is the study of the impact of a web site on its users" (Webopedia.com–Definition).
In this, web analytics software is used to gain insights such as number of visitors to the web site, the
way they reached the site, key words used while searching, time spent, etc. It is carried out to
monitor, correct and create a better user experience. Allen and McQuown defined web analytics "as
a process of analysing the behaviour of visitors to a web site" (Techtarget.com). They agree that web
analytics helps a firm to attract more visitors and retain them for goods or services. While Kaushik,

Web Analytics : A Tool For Business And Market Research
Web analytics is the study of how users interact with the websites by recording user related data,
which helps in identifying different aspects of user's behaviour. It is the measurement, collection,
analysis and reporting of web data for the purpose of understanding and optimizing web usage. Web
analytics can be used as a tool for business and market research and to assess and improve the
effectiveness of a website.
Web analytics essentially involves data collection and data can be collected in two ways, the
traditional method is a web server log file analysis and the second method is page tagging, which
uses JavaScript embedded in the web page. The collected data is processed to produce web traffic
reports. The companies use different web analytics softwares like Google Analytics, Omniture,
Coremetrics etc. to find out information about their visitors, including how they interact with the
pages in a site, how long they stay on their site, how many people visited their site, how many of
those visitors were unique visitors, how they came to the site and what links they clicked on and
when they left the site. Web analytics can give a significant competitive advantage to a company;
one of the best examples is 'Amazon'. Amazon uses analytics at every level and scale. Amazon has
it's own analytics tool called 'Amazon Web Services', which collects the data about the customers
who visit their site, analyzes the data collected to uncover the buying patterns of different customers

The Construction Of Red Black Trees
1 Introduction
In recent years, much research has been devoted to the construction of red–black trees; nevertheless,
few have refined the confusing unification of Internet QoS and active networks [3,13,23,18,8]. The
impact on random robotics of this has been adamantly opposed. An essential problem in hardware
and architecture is the synthesis of checksums. To what extent can hash tables be developed to
address this question?
Statisticians never enable the Turing machine in the place of robots. Such a hypothesis is mostly a
confirmed aim but fell in line with our expectations. Indeed, Web services [22] and public–private
key pairs have a long history of interacting in this manner. Indeed, operating systems [30] and RAID
have a long history of interacting in this manner [35,22,19,33]. The basic tenet of this method is the
visualization of hierarchical databases.
Another essential riddle in this area is the emulation of cache coherence. It should be noted that
LactylMuset locates local–area networks. However, large–scale configurations might not be the
panacea that systems engineers expected. Even though similar approaches improve the memory bus,
we achieve this goal without harnessing the compelling unification of operating systems and
context–free grammar.
LactylMuset, our new heuristic for perfect archetypes, is the solution to all of these grand
challenges. The disadvantage of this type of method, however, is that the foremost large–scale
algorithm for the exploration

Impact Of Cloud On The Organization 's Network Infrastructure
Introduction:
The central theme of this essay focuses on the impact of cloud on the organization's network
infrastructure. While going through the impact we will also analyze how to optimize network
performance for cloud and we will also discuss about how the cloud impact the lifecycle
orchestration and the organization. The key aspect o the cloud is discussed in detail with suitable
examples.
Background:
The cloud computing is noting but storing the data and information n the internet, instead of saving
the data on the computer hard drive. Since the data and information are stored in the cloud, it
becomes easy to access the data from anywhere in the world (Griffith, 2016). Due to the data
availability the data integrity is affected in the cloud. Cloud provides a flexible bandwidth, if the
organization demands increases we can scale up the cloud capacity. The maintenance cost is low
(cloud , 2015). Due to this reasons the organizations are moving towards the cloud.
Due to the changing need of the IT the cloud also changed, it has combined with WAN and SD–
WAN. Due to this the managing if cloud in a large organization has become easier. In summary we
will discuss in detail about cloud as organizational WAN. The other aspects like optimizing the
network performance is also discussed in detail.
Optimizing network performance for the cloud:
The cloud makes a few organizations overlook the essentials of IT, things like capacity
management, change control, and network

Future Implementations Of The Service
future implementations of the service instead coupling the service an an expected path URI scheme.
A disadvantage of query string style parameterization over path style is that the latter is more likely
to be cached by modern browsers. We provide a reference implementation
[14] of embedding the service in the OpenWayback interface12 (Figure 10), invoked by specifying
the access=wayback query parameter.
When a user queries the service, the URI parameter is used to build a request to the Internet Archive
(IA) using Memento. The service receives the response from
IA, adhering to the patterns described in the Memento
RFC [21], and proceeds to extract relevant information from the TimeMap to build the local
structures for client–side data management. From this list of URI–Ms, each is queried and when the
DOM is fully loaded, the
HTML is returned to the service for further analysis.
Complete loading of the target memento is necessary to allow any DOM modification by embedded
JavaScript script to be executed. From each memento's HTML, a SimHash value is created and a
Hamming distance calculation is performed with k = 4, as determined to be optimal by AlSum [2].
When the set of eligible mementos has been established, a template is returned to the client as a user
interface with placeholders for the screenshots to be generated asynchronously. From
12 https://github.com/iipc/openwayback those mementos that meet the threshold, a subsequent
request is sent to IA using PhantomJS13 (a

Software optimization is process of changing a software system to enable some aspect of the process
to work more efficiently using less memory storage and less power.
Profiling and timing code execution:
We need to identify portions of code that run frequently which are called hotspots and make these
identified hotspots run faster.
In Profiling the first step is to understand the code in terms of its computations and requests.
Next we need to identify any bottlenecks that may disrupt the performance.
Third we need to set objectives.
Finally we need to improve the performance cycles.

More the requirements implies slower network solution.
In order to do this we need to consolidate the CSS and the JS files, Embedding CSS images into
CSS which reduces extra space, load images only as they scroll into our view.
Next we need to reduce the bytes which also leads to slower network solutions.
For this we need to enable zip compressions, compress images fully and resizing the images as per
the screen size.
Slower javascript leads to weaker CPU:
For this we need to make sure that javaScript is async to the page load.
Asynch avoids delay.
We need to also remove the unused codes.
Numerical methods:
Linear programming:
The objective function is a real–valued function which is defined on a polyhedron. Main function is
finding a point in the polyhedron that has the smallest or the largest values if and when a point like
that exists.

Quadratic programming:
QP is minimizing/maximizing a quadratic function which consists of variables that are subject to LC
on these very variables.
Stochastic programming:
This is mainly used for modeling problems that have uncertainity. Almost all of the Real world
problems include unknown parameters(atlleast few).
Advanced optimization:
Hill climbing:
Hill climbing is used for reaching the end state from the first (start) node. Decision of the next nodes
from the starting nodes, can be done by various algorithms.
There are two variants of hill climbing which are simple hill climbing

The Choice Of Cpu And Intel Core I7
1.0 Choice of the CPUs
The choice of CPU will influence the other decisions one makes about the ability to find a
compatible motherboard, CPU cooler and (to some extent) power supply. The Intel Core i7 4820K
and the Intel Core i5 –4670K can be easily differentiated. The main Characteristics of both are
explained as follows:
a) General Characteristics of Intel Core i7 4820K
1. The Operating frequency is higher in Intel i7–4820K.
2. The Intel Core i7–4820K is not "locked", that is, the processor can be easily over clocked on most
motherboards for better performance.
3. This processor includes Advanced Encryption Standard technology which provides AES
encryption acceleration to secure the disk data.
4. The i7 is hyper threaded, which means that it can handle twice the amount of threads than i5,
putting it at a capacity of eight simultaneous threads. b) General Characteristics of Intel Core i5
4670K
1. The Intel Core i5 comes with higher operating frequency than the Core i7.
2. Power usage of the microprocessor is better.
3. AVX, AVX2, F16C and FMA3 instructions are included in the Core i5–4670K. These extensions
are not widely used in applications.
4. The i5–4670K combines Graphics Processing Unit that can be used for casual gaming and 3D
apps, but it is not too fast to run latest games at full resolution.
5. The i5–4670K uses The Socket 1150, which is still effectively supported by Intel.
1. b Performance
CPU performance of Core i5 parts is slower than that of Core i7.

Web Analytics : Information Gateway For Customers
In today's world, for almost every business, it is essential to have a website which serves as an
information gateway for customers to gain insights into the business. In return, a website is also a
tool through which business analysts can understand more about the behavior of customers. This
would mean that tracking and analyzing website data is crucial to making sound business decisions,
hence the growing favor for Web Analytics. Web analytics is the practice of measuring, collecting,
analyzing and reporting on Internet data for the purposes of understanding how a web site is used by
its audience and how to optimize its usage. There are five steps in this continuous and repetitive
process: Collect, Measure, Report, Analyze, and Optimize. First of all, the analyst needs to identify
the client's goals and objectives. This is to make sure that both of them are on the same page and
looking to achieve the same target. Any discrepancy or misunderstanding in this step can cost a huge
amount of time and efforts later when they move along with the project. The goal categories are
Revenue, Acquisition, Inquiry, and Engagement – the larger business objectives that most
campaigns seek to accomplish. Some typical objectives can be, for example, leverage brand image
or boosting sales. Second, the analyst uses web analytics software to collect relevant data. This web
analytics software can be Google analytics, a free tool that is provided by Google. Next, the data is
to be compiled in

Scalability at Youtube
Scalability at YouTube
Problems Youtube was facing
First of I will start talking about the problems they faced at YouTube was facing. YouTube has faced
a lot of problems in its life time so far and the main issues they faced were with scalability. The
main reason YouTube faced so many issues was due to its large and rapid growth, YouTube went
from a small website to a technology giant and large player in the IT industry practically overnight.
The solution to dealing with this large and sudden growth was to keep things simple, by using
simplicity this allowed YouTube to cope with the large growth. The simplicity approach was used to
conquer a lot of problems. Make it simple, look for the simplest solution to a problem, sure the
problem ... Show more content on Helpwriting.net ...
At YouTube the use of python makes doing this easier as the dynamic nature of python makes it
easier to do. In other words "no matter how bad your API is you can stub or modify or decorate your
way out of a lot of problems".
Other scalability techniques used by YouTube would be to say that they cheated a little or to say
instead of data being correct it is approximate correctness. What is meant by cheating is that not all
of their servers are consistent at the same time a good example of this is that if a user writes a
comment on a video then instead deploying that comment to all servers in the network and keeping
all data consistent what they have done at YouTube is they done it so that the system does not have
to have globally worldwide consistent transactions. Meaning that when the a user rights a comment
on a video he/she sees that comment instantly however someone on the other side of the world may
not see that comment for a couple milliseconds, in other words the cheat. The data will be consistent
in the end, the comments are not financial transaction therefore it is essential that you know when to
cheat, for example if it was a financial transaction where a user is purchasing something then it is
not good enough for the data must be consistent. Another main part of the cheating technique is
knowing when to fake data, for example to say that "The fastest function call is the one that doesn't"
or hasn't

GMail Image Caching Measures the Effectiveness of an Email...
Why Gmail's Adding Image Caching is Important
Because image tracking can be used to measure the effectiveness of an email marketing campaign,
based in some part on the open rate, it has become a fundamental part of the email marketers took
kit. Therefore, Gmail's decision in December 2013, to add image cashing, seems to have created
concerns for a great many people, not all of these concerns can yet be answered. It is also worth
remembering that Gmail has in the past decided to roll things out, and then taken the decision to roll
them back in favour of a phased transition to deployment.
According to Google the reason they have made these changes is to "make messages more safe,
secure and faster than ever before" whether using your computer ... Show more content on

Reputedly, Google claim to have resolved the malware issue by hosting images via a proxy server.
This means that any embedded malware contained in an email won't show up. Security researchers
claim that this new technology poses an even more serious threat, in that Google are now able to
read its users messages both without their permission, and whether or not the messages have been
opened. There have also been claims that spammers are able to email the same image to everyone,
assigning every image with a unique url. Each url would then provide a tracking facility informing
spammers if the email had in fact been opened or not.
Google responded by saying they offer a feature that allow users to 'opt–out' of displaying any
images in emails. They also said that they can remove the proxy server if the image display was a
problem, and require the user to press 'show images.'
The Impact on Using Email Marketing for Businesses
For users of Gmail the changes simply mean that images contained in the emails they receive will be
automatically displayed in the messages, without the need to click on a link to view it.
Businesses that use email marketing, specifically analytical packages, the data of certain data could
be affected. The data will now be sourced from the Google proxy servers as opposed to previously
pulled directly from recipients directly opening the marketing messages. Whilst

following the questions:
– What are our online prospects viewing?
– What are our customers buying and not buying?
– What content are visitors viewing very briefly versus viewing for an extended period of time?
There are so many drill down possibilities from those 3 questions alone that can lead significant
website content improvement. The art of web analytics is used to answer those questions and many
more. The key to website analytics is to effectively track behavior so that it can be studied and

These metrics create a reasonable summary of how many different individuals are visiting a site
over a period of time. Individuals are a defined by a cookie ID that is assigned when a new IP
address attempts to access a website. It is visitor behavior that is studied for the goal of optimizing a
website a website. In 2012, the American Cancer Society utilized web analytics to understand how
visitors interacted with their site. The American Cancer Society used visitor data to isolate
individuals into three segments: information seekers, event participants and donors. Analytics
allowed the American Cancer society to determine if:
– Information seekers were gathering the necessary information by viewing the appropriate pages.
– Event participants were completing registration.
– A donation was made.
By looking at these areas quantitatively, the American Cancer Society was able to understand where
areas of improvements needed to be made. This is a very simplistic example of the metrics process:
Define, Measure, Analyze, Action, Improve or Eliminate. However the example shows that any
website can benefit from meaningful analytics. The American Cancer society utilized Google
Analytics to view and tracks those metrics. Google Analytics is the most widely used, free, web

The objective of this stage is to take the data and transform it into information, specifically metrics.
Developing KPI: This stage focuses on using the ratios (and counts) and infusing them with
business strategies, referred to as Key Performance Indicators (KPI). Many times, KPIs deal with
conversion aspects, but not always. It depends on the organization.
Formulating online strategy: This stage is concerned with the online goals, objectives, and standards
for the organization or business. These strategies are usually related to making money, saving
money, or increasing market share.
Web Analytical Tool:
There are various web analytic tools used such as Google Analytics, Clicky, Mint, Church Analytics,
Open Web Analytics, Click Tale, Crazy Egg, Piwik etc..,
Google is using web analytics techniques in Google Ad Sense products to find and identify the
unique visitors on a particular web page. Google gets to know if the visits on the webpage are
unique and genuine or if they are repeated visits from the same users. Google Ad Sense thus helps
its customers by providing correct information about the site visits and various logs.
There are various techniques which can be used to performance tune our websites.

Web Analytics : Online And E Commerce Activities
Web Analytics: Web analytics is a set of strategic methodologies implemented to maximize online
and e–commerce activities. Web analytics extracts and categorizes qualitative and quantitative data
to identify and analyze on–site and off–site patterns and trends. Analytic techniques and
requirements vary according to organizational requirements. Web analytics services may be
supplemented with related sources, including email marketing response rates, direct mail, sales and
website performance data. With the help of Web analytics admin can be able to determine the
number of users hit the website and how long they were on the site during the visit. Using the web
analytics administrators can monitor whether the site is working fine or not, determine the area of
interest of customer in the site and where they do not get traffic. It provides the administrators and
publishers, the data that can be used to modify the website for the better user experience. Page
Caching: The amount of real–time(dynamic) information that displays in web pages will correlate
directly to the server resources, memory, and processing cycles that are being used, which affect the
effective speed of the page loading. By caching the pages, they are saved in their fully rendered
state, by which we can achieve performance that nears that of static web pages. Page caching is a
process of storing (caching) this HTML on the server, during the time of generation of these
WebPages, so that the next time

Web Analytics Analysis And Reporting Of Web Data For...
Web analytics is the measurement, collection, analysis and reporting of web data for purposes of
understanding and optimizing web usage. It is used to enable a business to attract more visitors,
retain or attract new customers for goods or services, or to increase the dollar volume each customer
spends. Web analytics is often used as part of customer relationship management analytics. The
analysis can include determining the likelihood that a given customer will repurchase a product after
having purchased it in the past, personalizing the site to customers who visit it repeatedly,
monitoring the dollar volume of purchases made by individual customers or by specific groups of
customers, observing the geographic regions from which the most and the least customers visit the
site and purchase specific products, and predicting which products customers are most and least
likely to buy in the future. The objective is to promote specific products to those customers most
likely to buy them, and to determine which products a specific customer is most likely to purchase.
This can help to improve the ratio of revenue to marketing costs. In addition to these features, Web
analytics may include tracking the clickthrough and drilldown behavior of customers within the Web
site, determining the sites from which customers most often arrive, and communicating with
browsers to track and analyze online behavior. The results of Web analytics are provided in the form
of tables, charts, and graphs.

Role Of The Frame Table And The Disk Map Data Structures
CH 8
1. In a 5–stage pipelined processor, upon a page fault, what needs to happen in hardware for
instruction re–start?
When there is a page fault during fetching an instruction pipeline must be drained, so that the
instructions which are already executing show be finished first. After this we cater the page fault and
restart instructions.
Otherwise if there is a situation that page fault occur during MEM operation the instructions which
are in other states such as in instruction fetch, instruction decode or execute can be condensed as
they won't be making any changes to the registers. After this we can handle the page fault.
2. Describe the role of the frame table and the disk map data structures in a demand paged memory
manager.
Frame tables are used as a reference as we can get to know that which frames are available and
which are already taken and which process they are allocated.
Whereas the disk map data structures are used to know about the frames which are being swapped
from the disk and where they can be relocated again.

Computer Specification
The user's computer specification may be an element that influences the performance of a website
that the user is trying to load. There are a few factors in computer specification that may influence
the performance of a website.
ISDN
ISDN was the advanced version of a dial up connection. For example dial up had an average speed
of 56 Kbps but ISDN had more than double that speed and could be as quick as 128 Kbps. This was
the first method for extremely quick access to the web inside your own home. Some say that ISDN
was the start to the main methods we use now to connect to the web (Broadband and DSL). This
was a big step into making the internet popular and into what we have today.
DSL
This form of connection is the use of digital lines for connection to the internet. The most popular
type of DSL is ADSL and is 8 Mbps which is much quicker than ISDN. This form of connection is
effective because you can use the same line to use the internet and telephone at the same time.

Online Marketing Efforts And Increase Roi
Web analytics is the objective tracking, collection, measurement, reporting, and analysis of
quantitative Internet data to optimize websites and web marketing initiatives. The Web Analytics
Association (WAA) defines Web analytics as the measurement, collection, analysis, and reporting of
Internet data for the purposes of understanding and optimizing Web usage. Web analysts can reign in
data from "big" to "good," and make sense of it all. They sort the real–time data into good metrics,
useful metrics. They organize it into reports and analyze those reports to find insights to improve
their online marketing efforts and increase ROI. Web analytics can lead to a deeper understanding of
your target audience. Tracking and analyzing the behavior of consumer traffic on your website
paints a more insightful picture of how to build relationships with your audience. If you have solid,
accurate data to back up your strategies and decisions, then your chances of creating and executing
successful marketing campaigns increase exponentially. Web analytics is the study of visitor,
navigation, and traffic patterns to determine the success of a given web site. Focusing only on the
amount of traffic might only be helpful in evaluating your bandwidth usage and server's capabilities,
which is not its only purpose. Web analytics focuses on in–depth comparison of available visitor
data, referral data, and site navigation patterns. It also tells us the amount of traffic we

Cache And Various Mapping Technique
Abstract– This paper begins with the discussion about cache and various mapping technique. Then
we shift our focus on compressed caching which is the technique that tries to decrease paging
request from secondary storage. We know that there is a big performance gap in accessing the
primary memory (RAM) and secondary storage (Disk). The Compressed caching technique
intercepts the pages to be swapped out, compresses them and stores them in pool allocated in RAM.
Hence it tries to fill the performance gap by adding new level to virtual memory hierarchy. This
paper analyze the performance of virtual memory compression. Further to avoid various categories
of cache misses we discuss different types of cache technique to achieve higher performance. Lastly
we discuss few open and challenging issues faced in various cache optimization techniques.

Basically, cache is the smallest and fastest memory component in the hierarchy. It is aimed to bridge
the gap between the fastest processor to the slowest memory components at a reasonable cost. It
maintains the locality of information and support the reduction of average access time. The address
mapping converts physical address to the cache address. But when it comes to virtual memory
systems, swapping turns out to be the greatest factor for reduce in performance. Disk latency is

seldom is relational across multiple analysis models. Thus, one study doesn 't really relate to another
one from a database perspective.
In previous versions of our software, we often stored the data relationally in Access, SQL Server, or

didn 't really relate to one another, load the data in some form of hierarchial structure either with
ADO or COM object trees, work with the data, and then run expensive updates across myriads of
records with varying data types. In a desktop environment, you can get away with the extra

protocols, as it is very costly in ... Show more content on Helpwriting.net ...
The route cache may be containing the stale routes which can affect for the performance of DSR
protocol. The stale routes in the route cache of DSR protocol may take several adverse effects such
as long delay, packet loss. Route cache can be divided to the three different strategies cache
structure, cache capacity and cache timeout.
The DSR (Dynamic Source Routing) routing protocol dependent on the cache memory for every
node to store the routing path from source to destination. It is a new algorithm using DSR routing
cache technique to improve the routing between mobile nodes to reduction the effect of mobility in
link transmitting that can solve link broken problem.
2. PREVIOUS WORK DONE:
[W. Lou and Y. Fang 2002] proposed that the stale route in the cache of the DSR can be removed by
the Adaptive link cache procedure and then compare it with the path of cache structure. [B. Y. He,
2002] proposed "Active Packet" to resolve the problem of stale route in cache route in DSR
protocol. It depends on the link cache structure, which the active packet travels around the network,
and gathers routing information that has found by network topology. [J. Chen 2010] proposed Tiding
Active Packets (TAP) to improve the active packet method. [A. K. Dwivedi 2009] describe the

Website Analysis : Web Analytics
Web Analytics is a relatively new phenomenon in the business world, and while it is not a
mandatory requirement for organizations to compete in today's marketplace it is becoming
increasingly important as organizations strive to optimize their web presence. So what is web
analytics and how can it help companies achieve a better web presence? Web Analytics is defined by
the Web Analytics Association as, "The practice of measuring, collecting, analyzing and reporting
on Internet data for the purposes of understanding how a web site is used by its audience and how to
optimize its usage." (ClarkU, p. 1) To simplify this definition we can say that web analytics is the
process of determining how your website most effectively turns site visitors into customers.
Web Analytics can be broken down into two distinct categories which are Onsite analytics and
Offsite Analytics. Onsite Analytics gives you the narrow view of your website as it only measures
the visitor circulation on your website. This type of analytics would give your organization an idea
of what pages on your website are most successful in turning visitors into customers and on the flip
side which are the least effective pages. Offsite Analytics gives your organization a big picture view
into how your company's website compares to the websites of your closest competitors. While both
categories are very important to companies who are engaged in web analytics, I believe that offsite
analytics are much more important to an
