Big Dat The Good And The Ugly

Big Dat The Good And The Ugly
Big Data: The Good and the Ugly Richard Springs Texas A&M University San Antonio Abstract
Intro into Big Data Big data is a term that describes a large volume of data. This data comes in the
form of structured and unstructured data. Structured data is information taken and sorted in rows and
columns while unstructured data is pictures, tweets, videos, and location–based data. It is not
surprising to see many businesses today utilizing data for financial gain. Businesses are harnessing
data and using it to make investment decisions, marketing strategies, fraud reductions, and much
more. These businesses and organizations can expect to become more profitable, effective, and
efficient, but pushes the limits ... Show more content on Helpwriting.net ...
Velocity – Data streams at a groundbreaking amount of speed and must be measured in a timely
matter. There are new methods today which are used to measure big data in real time. Volume –
Businesses and organizations collect data from a large selection of sources. These include business
transactions, social media and information from sensor or machine–to–machine data. Storing these
data collections would have been a problem in the past, but with emerging technologies like cloud
computing, it has become easily possible. Variety – The format of data comes in many forms. These
forms include numeric data, text documents, email, video, audio, etc. How big data is mined In
order for business to harness big data, we must first look at how big data is created and stored.
Computers throughout the world obtain data through their hardware and software. The end results of
this collection of data as of 2014 is 11.2 zettabytes. Only one half percent of the 11.2 zettabytes of
data is structured and utilized today. This means that most data is not valuable because it is not
sorted. A business cannot utilize big data unless it is structured in a way to help a business reach a
goal. A way for the data to become useless is through data mining. Data mining is the practice of
examining large databases in order to generate new information. This new information is practical
and structured. The hardware The data cannot be mined

Advantages And Disadvantages Of Camelcase And Underscoc
Two naming conventions that can be used for the coding of this application is camelCase and
underscore_case. A particular naming convention is used for an easy identification of variables,
function and types. camelCase is the typographical convention where a name is formed up of many
words each having a capital letter at the start barring the first word eg. payPal, startTheFunction
(whatheco.de, 2017). This convention is mostly used in JavaScript and python however can be used
with practically all programming languages.This unique capitalisation process makes the name
easily readable. An advantage of cameCase is that any programming language where the letters in a
name must be contiguous (such as a variable), a more meaning full name can ... Show more content

Responsibilities of a user or developer
Discuss the different methods and structures the developers could use to back–up the development
of this application to protect against loss
One of the many responsibilities a developer or user has, is to back up the files. Three methods of
data backup include the RAID system, cloud, and grandfather father son.
RAID (redundant array of independent disks), is a method of staring virtual data on separate disk
drives that combine to make a single logical unit for the purpose of data redundancy. Data is
distributed to across the drives depending on the required level of performance and redundancy.
There can be up to 6 RAID levels. RAID level 1 consists of data mirroring without parity. Data is
written identically to two drives. When the data is requested to every drive in the set then it will be
serviced by the drive that read the information first. This method is slow because if one drive needs
updated then the other drive will need to be too. If one drive fails to function, it does not matter
because the second drive can still produce the same output. RAID 2 consists of bit–level striping

Child Care Setting

This is one of qualities digital information clearly lacks. One of the reasons why many people are
reluctant to digitize their paper documents. Also the digital storage has vulnerabilities like data
corruption, viruses, accidental deletions, software/hardware failures. Especially in a small childcare
setup, the additional cost of making such a transition can be a decisive factor. On the other hand
Paper storage require proper storage space and care to refrain from damage. Therefore striking a
balance between paper or digitized records in a childcare setting entirely depends on the business
size and its requirement. The provider has to decide, which method is most suitable for a particular
setting. Whichever method is chosen, the provider must ensure that the system is safe, secured,
accessible, accurate, legible, and meets all the statutory

Computers And Humans Technological Advances
Computers and Humans Technological advances have clearly been faster in recent years than in all
human history. Artificial intelligence is growing at such a rate that the possibility that it will, one
day, exceed human intelligence is becoming more conceivable. The last decades have undoubtedly
been the most prolific in the scientific and technological field. Never in human history has it been
possible for such progress that led to profound changes in our societies. In 2012, IBM, an American
technology company, announced in a report, IBM 5 in 5, that it would develop cognitive systems
that will allow computers and smartphones to use the five human senses. According to IBM (2012),
the sense of touch will be created by using haptic technology that generates a vibration when the
user touches the screen. As for the sense of sight, currently, computers can see images, but do not
understand them. IBM (2012) predicts an evolution in a near future where computers will be able to
develop this sense. This will benefit several fields such as the medical and agricultural fields.
Olfaction will also benefit these fields. Hendrik Hamann (2012), a research manager at IBM
affirmed that this will be possible thanks to sensors that can analyze gases and other molecules in
the air. Computers will detect if a user is developing cold or other illness symptoms. They will also
have gustatory perception. The sense of taste will be acquired by using algorithms to analyze the
molecular structure

software application that monitors network system activities for malicious activity or policy
violations and produces reports to a management station (Kashyap, Agrawal, Pandey, Keshri, 2013),
additionally there are three types of IDS:
Host based IDS – monitors a computer system on which it is installed in order to detect intrusion or

The Impact of Enterprise Storage Strategies
Introduction
When a business started, the related data has been generated. Along with the development of the
business, the data becomes larger and accumulates day by day. The accumulated data can be
transferred to meaningful information for the managers' decision makings. Storing and protecting
the data is essential to the development of the enterprise business. Today, almost all enterprises use
computer storage to store their data instead of the hard copy papers. In the past, hard copy papers
stored the data for the enterprise, but it existed too many potential risks, such as data loss, data
stolen, data destroy, or cannot sharing with others. In 1990s, more companies started to use
computer hard drive to store their business data; this change impacted the later development of the
storage strategies. Along with the technology development and the data becomes bigger and bigger,
big data problems appear. How can enterprise store such large data and manage such large data
effectively? Currently there are several classic storage strategies to help enterprise solve their data
storage problems, such as spinning media, flash, and cloud. The enterprise also can select onsite or
offsite option as their considerations based on their business environment. Security issues are
popular discussion topics as well in this paper.

Technology evolvement direction focused on storage devices and by 2012, the company now re–
named BOLDFlash, focused on flash memory with significant customer base in OEM (Original
Equipment Manufacturer) and direct to–consumer markets. As one of the most respected company,
BoldFlash build its reputation for quality with both competitors and customers. The company held
over 600 patents in the U.S alone with strong ongoing research lead by PhD–level scientist (Beer &
Shelton, 2012).
The company, although respected, has come under fire for not using their research for product
improvements or customer needs. BOLDFlash flaws have become apparent with the release of latest
product, the A23–B flash drive. BOLDFlash technical communication practice is affecting product
quality, delivery timeliness, efficiency, costs, and customer satisfaction. The company went through
major reorganization of divisions, experiencing rapid sale growth, high productivity of products, and
fast pace development of new products (Beer & Shelton, 2012).
The changes within BOLDFlash increased the challenge for an effective communication between
division teams, suppliers, partners, and customers. BOLDFlash technical communication practice is

A Short Note On Scsi Test Vehicle ( Stv )
Introduction
SCSI Test Vehicle (STV) is a project to develop an FCP Storage emulator using FICON Express
16G channel adapter present on System z machine. STV is a specialized Firmware (FW) load into a
channel adapter that provides the function of a FCP Target (Fibre channel SCSI Storage Control
Unit). STV emulates IBM shark disk storage.
This document is intended at describing the design and implementation of STV Emulation support
on Power Servers/Blades. The scope of this document is mainly limited to STV component in STV
Type FC channel firmware. This document contains information collected from other documents
and design discussions. STV Emulation support on Power Servers/Blades enables qualification/test
floor teams to use the STV Type channel firmware to test SCSI stream protocol capable devices not
just on system z but other servers such as zBX and zFX as well. Problem Statement
The Current STV based storage emulator requires a FICON express I/O Hardware and system z for
emulation. This is useful for testing in a System z environment but proves uneconomical in regular
zBX or zFX qualification. Moreover since STV uses the resources within the FICON express
module, which are limited. Emulation of Enhanced features such as multipath or increased LUNs is
not possible. This limits the test coverage of the test team. This project tries to work around some or
most of the limitations by moving STV emulation to a Power server.

Abstract Today's computers have different ways to store data. Some examples of these ways are
devices as the hard disk (aka magnetic disk), floppy disk, RAM, CD ROM, tape, and the flash (aka
jump drive, USB memory stick, and thumb drive). Storage devices come in two different sources;
primary or secondary. Each of these devices causes the computer to process data at different speeds.
This paper will show how each of these devices store data and how they affect the speed of the
computer.

The Flash (aka Jump Drive, USB Memory Stick, and Thumb Drive) is a small device that plugs
directly into a USB port on the outside a computer. It has made the transfer of data information very
easy. The flash can be used easily to access large reports, presentations, spreadsheets, etc. without
experiencing any slow response times trying to retrieve stored data on a computers' hard disk. It is
becoming a more preferred type of storage today because of its sturdy build making it easy to be
carried in a pocket, on a keychain, or even on a lanyard. This is another option that is an inexpensive
type of storage. As earlier defined, RAM provides fast access storage when a computer is on.
However, if there is too many things open at once RAM can become sluggish. Every time an
application or program is opened the RAM has that much more information and data to sort through
while trying to process the request. For the computer to run at an optimal speed, unused applications
or programs should be closed. This has an effect on the computers clock speed also. According to
Webopedia – Clock Speed (n.d.), "Also called clock rate, the speed at which a microprocessor
executes instructions. Every computer contains an internal clock that regulates the rate at which
instructions are executed and synchronizes all the various computer components." In conclusion
these comparisons discuss some of the different storage

has different functionality in the context of computational needs. These are mainly divided in to
primary and secondary storages. 2) The primary storage devices are generally volatile devices such
as Random Access memory (RAM), cache memory etc. which cannot hold data for long periods. 3)
The secondary storage devices are nonvolatile devices such as hard disks, floppy disks, magnetic
tapes etc. which can hold data for long periods. 4) The characteristics that define the storage devices
are speed, volatility, access method, portability, cost, and capacity. These characteristics vary
between different storage devices. 5) These characteristics leads to a memory hierarchy in which
primary storage stands in the position in the hierarchy with faster access speeds and higher costs per
bit of storage, and secondary storage tends to be in the lower portion of the hierarchy, with slower
access speeds and lower costs. 6) Magnetic storage devices store data by using magnetic charges. A
read/write head with magnetic field is used to read/write the magnetic storage medium. 7) The major
disadvantage with this magnetic storage is magnetic decay and magnetic leakage whereas the
magnetic charge may lose its charge over time and leakage tends to cancel the charge by different
data

6. What advantages do fuel cells offer batteries for use in portable electronic devices? Do they have
any disadvantages?
Fuel Cells generate electricity by consuming fuel (often methanol), while traditional batteries store
electricity and release it through a chemical reaction. A spent fuel cell is replenished in moments by
simply refilling its reservoir or by replacing the spent fuel cartridge with a fresh one.
Benefits of Fuel Cell:
 Because there is no combustion in a fuel cell, fuel is converted to electricity more efficiently than
any other electrical generating technology available today.
 There are no moving parts in a fuel cell stack, making them more reliable and quieter than
generators. Even the ancillary systems (fans, pumps, controls, etcetera) in a complete fuel cell unit
are relatively mature and simple technologies that should prove extremely reliable.
 Unlike batteries that must be disposed of once their chemicals are used up, fuel cell reactions do
not degrade over time and can theoretically provide continuous electricity.
 Traditional power plants must be large in order to gain efficiency, but fuel cells can achieve
higher efficiencies at any scale, making them perfect for small portable, residential, and
transportation uses.
 Because fuel cells are clean and efficient at any size, they can be located almost anywhere,
including dense urban areas where both air quality and

Data Archiving and Cold Storage
When data professionals say they want cold storage, it means that the data are not going to be
accessed very often, but they still want to keep that data. Cloud service providers and enterprises are
experiencing dramatic growth of data being stored in private and public cloud. Due to this, single
high–performance storage tier is often used for all cloud data which is causing the data storage costs
to rise at a higher rate. Most of the information is 'cold data'. That is infrequently accessed data. And
the only way to reduce cloud costs is by moving this data to a lower–cost cold storage tier. Due to
the cost factor involved in storing a large amount of information in the cloud, cold storage is rising
as a significant trend. It is a low– cost storage that provides an optimal, reliable, and secure data
storage solution for data. Cold storage files can be backed up with the rest of the records instantly

An OnDemand system has one library server and one or more object servers. An object server can
operate on the same server or node as the library server or on a different server or node than the
library server.
OnDemand client programs operate on personal computers running on Windows. Using the client
program, users can construct queries and search for reports, retrieve documents from OnDemand,
view, print, and fax copies or pages of documents, and attach electronic notes to pages of a
document. OnDemand servers manage control information and index data, store and retrieve
documents and resource group files, and process query requests from OnDemand client programs.
The documents can reside on disk, optical, and tape storage volumes.
When a user submits a query, the client program sends a search request to the OnDemand library
server. The library server returns a list of the documents that match the query to the user. When the

user selects a document for viewing, the client program retrieves a copy of the document from the
object server where the document is stored, opens a viewing window, and displays the document.

Wondershare Data Recovery
Ever since media storage devices were introduced, their risks were born along with them. The
storage of important data is one of the most important things one may need now a days. In order to
back up data, users use all kinds of ways. One of the ways to back up and store data is through
external hard drives on MAC. In here, you're going to get an overview and a step by step guide to
recover deleted external hard drive files on MAC. Part 1: Why would you need data recovery
software for MAC? We would need a data recovery software for MAC in order to recover deleted
external hard drive files on mac as well as recovering deleted files from MAC itself. The data
recovery software provides enough room for us in order to be able to recover deleted files from
almost anywhere where data is stored. This includes ... Show more content on Helpwriting.net ...
While data recovery process is mainly applied to accidental deletion of files from external hard
drive. There occur issues when the data is instead lost due to corruption etcetera of files. For this
situation, Wondershare data recovery offers a solution. Go to the standard mode of Wondershare
data recovery software and instead of the normal wizard mode, choose the 'Standard mode' and click
on the "Lost file recovery". The process of scanning will begin and soon, all the lost files will be
recovered. Looking for RAW files? No problem. Wondershare provides a whole another recovery
mode through which you can specifically search for the .RAW files stored on your external hard
drive. Do no want to wait long for the scanning to be completed? Don't worry. Wondershare data
recovery provides a solution for this as well. If you cannot wait for the long process of scanning to
be completed before being able to actually recover deleted external hard drive files on MAC,
Wondershare data recovery can save the scanning results and then you can resume the recovery
process by loading the previously saved scan

The Characteristics Of Computer Memory And Information...
Computer memory (an information storage device, a storage device) is a part of a computer, a
physical device or a data storage medium used in calculations for a particular time. Memory, like the
CPU, is an unchanged part of the computer since the 1940s. Memory in computing devices has a
hierarchical structure and usually involves the use of multiple memory devices having different
characteristics.
Computer memory provides support for one of the functions of a modern computer, the ability to
store information for a long time. Together with the central processor, the storage device is a key
part of the so–called von Neumann architecture, the principle underlying most modern computers of
general purpose (Tsien 52–59). The first computers used storage devices solely for storing the
processed data. Their programs were implemented on the hardware level in the form of hard–coded
executable sequences. Any reprogramming required a huge amount of manual work on the
preparation of new documentation, re–computation, the rebuilding of blocks and devices, etc. The
use of von Neumann architecture, which provides storage of computer programs and data in shared
memory, radically changed the situation. Any information can be measured in bits and therefore,
regardless of what physical principles and in what number system the digital computer (binary,
ternary, decimal, etc.) functions, numbers, text information, images, sound, video and other types of
data can be represented by bit string

The Invention Of Usb Flash Drive Or Usb Stick Driver
The invention of USB flash drive or USB stick driver is based on PC connectors condition at that

Invented the USB Flash Drive?, USB mass storage devices were first developed by a group of
computer companies including Intel, Compaq, Microsoft, Sony, DEC, IBM, and Northern Telecom.
They want to make a special basic device connection protocol to standardize the PC connectors; this
will facilitate data transfer and connection between devices. Universal Serial Bus or better known as

In securing data storage, information, and applications, USB flash drives use biometric software and
encryption as a liability or as a norm. The on–the–fly encryption system or OTFE is used to encrypt
large amounts of data in a transparent manner. An example is IEEE 1667, According to Brenda
Barron in his article IEEE 1667 format makes for cross–platform USB drive security, this is one of
the efforts to create a generic authentication platform that has been supported by Windows 7 and
Windows Vista, Service Pack 2 with hotfix. This explains that USB flash drive is one of artificial
intelligence, which can mimic cognitive function or human mind to learn to read data or interpret
complex data, store and recall data or encryption. In addition, smart routing on the content delivery
network. In some cases even in law enforcement, there is also software working on USB flash
drives, such as the Computer Online Forensic Evidence Extractor or COFEE application developed
by Microsoft. This is a set of applications used to search and extract digital evidence on computers
and USB flash drives. In addition, software or applications such as FreeOTFE are used for storing
data, configuration information, and others on a USB flash drive without the host computer 's
registry. In 2005, most USB flash drives support machine learning, which uses predesigned model
design and algorithms that match predictions for predictive analysis. Such as a

The Virtue Of Forgetting Of The Digital Age
Delete The Virtue of Forgetting in the Digital Age – Viktor Mayer–Schonberger
Chapter one is entitled " Failing to Forget the Drunken Pirate." This chapter starts off giving
examples of real people that have professional jobs that posted something online that later on came
back and ruined their lives in some way. One person was a woman by the name of Stacey Snyder
who was a 25 year old aspiring teacher. After completing all the coursework needed to become an
educator, university officials denied her of her certificate because of a picture that she posted on her
private Myspace account. The picture was captioned "drunken pirate" and she was holding a red
cup, the university officials claimed her behavior was "unbecoming." Although her page was
private, it was still easy for the officials to find this one image that ruined Stacey's career. In this
chapter it is stressed how easy it is to find information on anyone. Google actually keeps individual
records of people 's search history, web pages browsed, and keywords that they often search. Google
used to keep these records forever, but as of recently that changed and they are only kept for a short
period of time. Also in this chapter it is stated that there is no more privacy. Cell phones have GPS
receivers which allows our location to be tracked all day everyday. Because of this you can now
even track someone through GPS from a photo they've take. In chapter two "Importance of

digital devices to avoid altering, damaging, or destroying the digital evidence. Avoid using any tools
or materials that may produce or emit static electricity or a magnetic field as these may damage or
destroy the evidence" (Mukasey, 2008). The first item that I would collect as digital evidence would
be the external hard drive. It may contain all types of evidence such as: files, logs, pictures,
recordings, or even video logs. Before collecting it as evidence I would take pictures of the hard
drive, making sure to get the manufacturer and serial numbers, and then document it. Once
complete, I would seal it in an anti–static bag and label that as well. The second item that I would
collect would be the laptop. This could have all of the same type of information that the hard drive
has and also may contain copies, pictures, or the source code itself from "Product X." The laptop
may show whether or not he was sharing files or trade secrets with outside sources, or even if he

Computer Crime Investigations Essay
In simple terms, computer or digital forensic evidence analysis is the scientific collection of data
that is either retrieved or held by a computer storage device that can be used against a criminal in a
court of law. For the information to be used in court it should be collected before it is presentation;
therefore, there are a number of recommendations proposed to make sure that information collected
meets the intended integrity.
Information collected digitally from computers or media storage applications has protocols that need
be followed during the process. The order of collecting digital information mostly determines the
life expectancy of information collected (Eoghan, 2004, p. 74). There is a need to change

Some of the most important procedures used in collection of information to be used in a court of law
include collecting live data from the RAMs images. Such live recovery of information can be
collected from the F–Response which can collect data from the networks of a computer. Information
can be collected when the computer is logged on or connected to the network or when the computer
is executing (Carrier, 2006, p. 56). The other procedure that can be used in the collection of
information for forensic purposes is the encryption of hard disks. Encryption of the hard disk creates
logical images that can be collected using the F–Response (Eoghan & Gerasimos, 2008, p. 95). The
other important procedure for collection of information is making sure that all data storage devices
are kept away from magnets and any other devices that might destroy data stored in them. It is
important that the handling individuals obtain the information collection manuals that help them
collect information effectively (Eoghan & Gerasimos, 2008, p. 94).
It is important that a financial crime investigator obtains all information generated by the computer
by analyzing the caches left in the hard disks. Data recovery from the RAM and any other external
drives makes data collected effective and applicable in a court

The Convergence Of Methods Of Storing Files
Americans today have seen the progression from old media to new media; majority, experiencing
for themselves the transition from pagers to cell phones, cassettes to iPods, or paper maps to GPS
devices. According to Henry Jenkins, who studies media convergence, this "Convergence [where old
and new media collide] represents a cultural shift as consumers are encouraged to seek out new
information and make connections among dispersed media content" (Jenkins 457). It is through the
help of convergence that old media has developed into the new media Americans see today. The
convergence of methods of storing files is an example of this. Storing files online, is taking the old

Dropbox is a cloud storage service; a business that overlooks a users' data and makes that data
accessible online. Because Dropbox has introduced people to the idea of accessing wireless data,
this reveals how this type of new media has changed the way that content is produced, distributed,
and consumed. Although the use of either a USB Flash Drive (old media) or Dropbox (new media)
maintains the same objective, that is, to provide people with alternate methods of storing data,
Dropbox is becoming a standard way of accessing data with the use of the internet as a platform.
This in turn, benefits Dropbox users somewhat.
One benefit of transitioning from a USB Flash Drive to Dropbox is that Dropbox allows easy access
to documents. "Dropping" files into Dropbox essentially stores these files on the online cloud, where
users can access their files anywhere and at any time as long as users have access to internet
connection. There are three methods in which Dropbox users can easily access their documents. The
first is through the Dropbox website. Users could simply sign–in and upload a document they would
like to save or download an already saved file, make revisions to it, and upload the revised
document. Another way Dropbox allows easy access to documents is by linking a users' Dropbox
account to their mobile device. This could

Fire Wire Advantages And Disadvantages
Fire Wire is a standard high–performance cable, used to connect multiple devices together or to a
computer. Fire Wire is also capable of very high speed communications and quick real–time data
transfer. It is also called the 'IEEE 1394'. The number of pins on a Fire Wire cable can vary, it can
either have 4,6 or 9 pins. The maximum voltage it can carry is 30 volts. The data exchange rates on
a standard Fire Wire 400, also called the 'IEEE 1394a', can go as high as 400 mbps. However the
new Fire Wire 800, also called the 'IEEE 1395b', has data transfer rates of up to 800 mbps. In the
future the data exchange rates can go up to 1600 mbps and 3200+ mbps. A Fire Wire cable is very
easy to use. It is a plug and play environment which means that the wire can be used as soon as it is
plugged in, no need for system configuration. Using Fire Wire cable is as easy as plugging or
unplugging a your computers power cord. There are quite a few benefits of Fire Wire. Fire Wire has
faster data exchange rates (100 Mb/s) in comparison to USB 2.0(60 Mb/s). A Fire Wire port can
easily be found on most laptops and computers. However there are som down sides to this. The data
exchange rates are very slow in comparison to newer, more widely available connections like USB
3.0 ( 625 Mb/s) or Thunderbolt (1.25 Gb/s). The use of Fire Wire is becoming very limited, most
new computers don't even feature them anymore like Mac's ( even though Apple made them). USB

Private Vlan Must Be Made Of Primary Vlans
private VLAN must be made of primary VLANs, which will contain promiscuous ports and
secondary VLANs which will contain isolated and community ports (Santana, 2014, p. 80). 6. Site
VLAN: Site VLANs are used on only one site for the purposes of "discovery and adjacency
maintenance between edge devices" (Santana, 2014, p. 358). 7. Voice VLAN: This VLAN is
exclusively for Voice over IP (VoIP). The network must be customized for this traffic by having
adequate bandwidth, giving the VoIP traffic precedence over other network traffic, and minimal
delay (Cisco, 2014, Section 3.1.1.4). b. VRF VRF stands for Virtual Routing and Forwarding
(Santana, 2014, p. 89). This technology allows the router to run more than one routing instance at a
time, saving money on equipment and increasing efficiency. It also separates the traffic on the router
automatically on the device, which increases security for the network (Patterson, 2009, para. 1). c.
Data segmentation: Methods of Network Segmentation Network segmentation is dividing parts of a
network for performance and security purposes (Cordray, 2015, para. 2). Companies need to
separate departments based on the security levels of the employees within those departments to
ensure that no employee can access information that they do not need. Segmentation is also done to
provide security from outside attacks by setting up a number of boundaries the attacker would have
to go through to reach confidential data (Peterson, 2016, Section 2).

A Brief Note On The Twisted Pair Cables
2.3.3 Twisted Pair
There are two types of Twisted Pair Cables, Shielded Twisted Pair (STP), and Unshielded Twisted
Pair (UTP). Shielded Twisted Pair Cables have a very thin wire mesh that shield and protect the
transmission. STP cables are used for the older phone networks, as well as data and network
communications which are clearer and have less interference with the outside. Whereas Unshielded
Twisted Pair Cables have no wire mesh and are therefore not protecting the transmission in the
wiring. UTPs are mainly used for Local Area Networks (LAN) as well as telephone connections,
however these are more vulnerable than STPs (Shielded Twisted Pair).
3. Backing Storage
3.1 Types 3.1.1 Disks
You can back up your storage on a separate Hard Disk and on other forms of Disks such as a Floppy
Disk. Using another Hard Disk to back–up your storage is useful because it means that you can
back–up everything that is stored on the Hard Disk you want to back–up. However it all depends on
the size of Hard Disk you get. If it's much smaller than your current Disk, then you will only be able
to back–up the more important stuff that is stored on the Disk. Whereas if you got a Hard Disk that
is bigger than your current Disk, then you will have room to back–up the whole Disk, as well as add
extras when you need to back–up more recent data.

Pen drives can be used to back up data by putting them into the USB port of the device you wish to

Advantages And Disadvantages Of Primary Memory
Random–Access Memory (RAM), Cache, Hard Disk, Read–Only Memory (ROM)
(i) The main disadvantages of primary memory are that it has a relatively smaller storage capacity
and is volatile which means data stored in the primary memory is temporary and is lost when the
computer or laptop is shut down and is no longer powered. Primary memory devices are also
relatively more costly to purchase and install in the computer.
(ii) The main disadvantages of secondary memory are that it is located further away from the
Central Processing Unit (CPU) and therefore, the speed at which data stored in secondary memory
can be accessed is slower.
Combining the two types of memory into one single memory device is not likely to be feasible as
the two memory devices (primary and secondary) are designed to form a memory hierarchy in the ...
Show more content on Helpwriting.net ...
Thus, the hierarchical system of accessing data in the primary and secondary memory devices at
different speeds will not work. This may result in an overall reduction in the speed at which data in
the memory device is accessed by the
CPU, thus decreasing the performance of the CPU.
A single memory device may also result in overheating and a higher energy consumption. Also, a
single memory device that incorporates the features of both the primary and secondary memory
devices may be costly to manufacture and thus, may not be affordable for all users.

The fans normally suck in air from the back and discharger of the front, also air vents in the sides of
the PC cases will help the air flow keep the PC cool. The power supply is the component to a
computer that will supply power to all the other devices and components. The power supply 's
voltage depends on what kind/advanced you're other components need and if you give your
computer more than you need then it may over heat and if you give your computer less it may run
slowly and keep on crashing/freezing. The power supply in constantly feeding power to the
computer and will gain heat very fast, to stop the power supply from overheating or becoming too
hot there are built in fans to keep it cool. The power supply gets all of its electricity power from the
mains in your house/office which means that some old power supplies could break from power cuts
or surges, todays versions have a fuse in to stop the supply from breaking so easily. Primary storage
is basically the computer's memory that is accessed by the CPU. Some examples of primary storages
can be ROM, RAM and the processor cache. The reason why there are so many storage devices is
because some are much faster to access, for example applications will load through your RAM as it
is faster than getting it through your storage device. RAM is used every time to open a program
from the hard drive, this is because it's faster. The ROM is storage the computer uses to start/boot up
your computer when you

Knowing this can help you save in cost. A business normally will look for a better file access speed.
G&J Consultation might need a fast performance storage since they are providing consultant
services to customers which the date stored might be use frequently and need to response to
customers very quickly. Transfer speed over the network is the primary indicator of a NAS because
it uses file–level protocol when uploading or downloading large files. NAS can provide performance
benefits. For example, NAS can take over the work of serving the email data, freeing resources on
the email server for email–specific processes. Scalability Scalability is important in terms of both
computing power and storage capacity. The performance and capacity should scale independently of
one another. Scalability is important because the ability of the storage would need to be expanded in
future in order to cope with increased use. NAS is a suitable storage which suggested for G&J
Consultation Sdn Bhd because it is easy to set up and easy to use, even a non IT based staff can
manage the NAS. Reliability Reliability of storage also is one of the factors which is very important
and need to be concerned. Reliability is important because the loss of data and downtime can lead to
loss in revenue and threaten the survival of the business. In today's world, most of the people
demand a highly reliability, shared storage device that is accessible to multiple network

The availability of the system can be compromised through a variety of ways. The inattentive
maintenance worker can destroy the network connection by cutting the power to the system or
destroying the lines of electronic communication. The system can also be overrun by activity which
leads to shutting down the system. Companies try to mitigate their servers from crashing by using
more powerful hardware and streamlining the application systems to be as efficient as possible. The
accidental interruption of the flow of information can be frustrating and costly to business but the
intentional destruction of hardware, software, or other components must be mitigated through
continuous security efforts.
A denial of service attack is a malicious attack by hackers via the web on a system to overcome its
ability to properly handle the information that it is receiving. The purpose of the denial of service
attack is to prevent the authentic communication between parties and closing down the system. This
is accomplished by forcing requests to verify a connection, ping requests, at an ever increasing rate
until the system is tied up, flooding the system with connection requests that cannot be
accomplished, or by attacking the buffer. The Buffer Overflow attack provides excessive amounts of
information that exceed memory size of the buffer and allow the attacker to enter their own code in

efficient choice for customizing their PCS. This is the most important section of the document and it
deals with the assembling, configuration, and installation the PC components. Even though this task
cannot be detailed in a short document of this length, I will try my best to summarize the process in
a simplest possible manner. The assembling of the software components of PC can easily be done by
using some of the available online resources. Therefore, I have intentionally excluded those steps to
shorten the document. The users of this guide are urged to refer available online videos for
additional references concerning this subject and any other information they might need.
Customization of a PC can be done just by replacing a single component or multiple components.
Whether the customizing is for improving the performance or for replacing a broken component,
making a mindset for customizing comes in first place. Users are required to buy desired
component/components following the guidelines provided in the earlier section of this guide. Since,
customizing requires the installation of one or more components based on the user's preference and
necessities, I am giving brief guidelines for installing the system unit followed by its

Enterprise Storage Systems : A Efficient Repository For...
Enterprise class storage Earlier many organizations placed storage and backups at the bottom of the
IT Priority list. Only organizations in the World Trade Center that had robust data backup systems in
place managed to survive. Today, storage, backup, and disaster recovery is a high priority for every
organization. The two levels of storage system is live storage and backup where backup is
increasingly becoming more and more critical. Enterprise storage is the computer data storage
designed for large–scale, high–technology environments of modern enterprises. Enterprise storage is
a centralized repository for business information that provides common data management and
protection, as well as data sharing functions, through connections ... Show more content on

Through the SAN, multiple paths are created to all data, so that failure of a server never results in a
loss of access to critical information. Enterprise data storage has the story of transitions from one
medium to another as the IT industry searched for ways to hold data and deliver access to it fast
enough to keep processors busy. Here, the following are the statistics of earlier storage devices.

Storage is required by a computer because its memory loses all its data when it 's switched off;
DRAM is volatile. When a computer is first switched on its memory is empty and both code, which
tells the computer what to do, and data, the information that is processed, needs loading into
memory from a persistent – non–volatile – store.
Direct attached storage (DAS), storage area network (SAN), and network attached storage (NAS)
are the three basic types of storage. DAS is the basic building block in a storage system, and it can
be employed directly or indirectly when used inside SAN and NAS systems. NAS is the highest
layer of storage and can be built on top of a SAN or DAS storage system. SAN is somewhere
between a DAS and a NAS. Direct Attached Storage (DAS) the most basic storage subsystem that
provides block–level storage and it 's the building block for SAN and NAS. The performance of a
SAN or NAS is ultimately dictated by the

The Information Security Risk On The Life And Solutions
Introduction
In this generation of advance Information Technology, people exchange the information using
numerous devices to accomplish their task in routine life. Information which used to be recorded on
paper is now taking form of electronic record. Personal Information is now more feasible to access
or destruct for the attacker because of weak IT security like virus or attack to the system or network.
To protect the privacy, individual should secure their information. However, the only way to
determine flaws and recognize threats, weather it is technical or non–technical or any other, is to
find vulnerability and perform risk assessments. In this paper, we will discuss the information
security risk in the life and solutions to mitigate ... Show more content on Helpwriting.net ...
For the information security, it is essential to find risks related to the use, processing, storage, and
transmission of information or data and the processes and systems used for that.
Unauthorized access, usage, recording, modification, distraction, etc. are the risk to the information
security. There are many different ways through which personal information can be lost or accessed,
misused, modified, or disclosed. Common risks to the information security are described below:
Unauthorized access or misuse of records by a friend or colleague or any other familiar person.
Hacking or other illegal acquisition of system or device database or information by outsider.
By mistake disclosure or sending of information to wrong person or organization.
Failure to store or organize information properly and securely.
Loss or theft of portable storage devices, paper documents, computer or any other equipment
containing personal information.
In order to develop a proper security which can protects critical data, systems, and other resources,
individual must first understand what it is facing in terms of potential sources of harm that may
exploit existing vulnerabilities. Threat assessment identifies potential sources of attack to
information assets and estimating the probability and consequences associated with their action.
Understanding of the source of attacks, along with their likelihood of
