Big Data Has Taken The Business World By Storm
Big Data has taken the business world by storm. By 2020, it is expected that the amount of digital
information in existence will have grown from 3.2 zettabytes in 2014 to 40 zettabytes. Companies
are doing all they can to capture this digital information and turn it into actionable insights.
Currently, the total amount of data being captured and stored by industry is doubling every 1.2
years. Therefore, companies must find increasingly efficient solutions to store and analyze this
incredible amount of data. One solution that continues to grow in popularity is Apache Hadoop.

In 2014 AWS captured 28% of the worldwide market almost triple that of its closest competitor
Microsoft at 10%. One of the main reasons for this huge lead in market share is AWS' breadth of
offerings which have extremely wide business applicaiton. Their web services include core cloud
infrastructure services like virtual servers, object, block and archive storage, and virtual private
cloud. In addition they also have several services dedicated to mobile, enterprise, and analytics.
Listed first under the analytics section on their website is Hadoop. Amazon Elastic Map–Reduce is
the web service that provides a managed Hadoop framework. Amazon EMR is able to most big data
use cases including log analysis, web indexing, data warehousing, machine learning, financial
analysis, scientific simulation, and bioinformatics. Another aspect that puts Amazon at the front of
the IaaS industry is that they are continually updating their products. For example, this June they
announced that users could now run parallel Hadoop jobs on their Amazon EMR cluster using AWS
Data Pipeline. This ability to run parallel Hadoop jobs on their clusters allowed users to significantly
increase the utilization of their cluster. For other cluster management issues, there is Amazon ECS.
Amazon ECS focuses on the management of followers, dispatching of sub–tasks to the proper
location, and state inspection of the cluster are all

How could something like this happen on American soil? In quick retaliation, President George W.
Bush forcefully declared a war against terrorism and specifically against those responsible for the

People's imaginations start to go wild when they hear the word torture. However, there are enhanced
interrogation techniques that are more humane than others. Waterboarding, for example, simulates
the effect of drowning and is highly recommended by people such as former Vice President Dick
Cheney (Defrank). It is highly unpleasant, but breaks no bones and leaves no bruises. It also exposes
those performing the interrogation to lesser psychological strain than other methods that could be
used would. Torture is accused of being a cancer in society, but if regulated and reserved for the
"especially" bad guys, societal homeostasis would be maintained. Torture also has been accused of
not producing reliable information (Hajjar). People argue that people will confess to anything if
tortured and even reference events in history such as the Spanish Inquisition. It must be understood
that if torture were to be legalized, it would not be used often. It would be reserved for the select few
when occasion would arise, that have pertinent information that could help save lives. Bush even
mentioned out of the many people that they captured, only three people were subjected to "enhanced
interrogation." Results were proved reliable as the Al Qaida leader, who was planning an attack on
the tenth anniversary of 9–11, was found (Richey). Torture, when done right, can produce valid
intelligence. We have proven with the capture of Osama Bin Laden that we can

Wireless Communications, The Radio Industry
With the recent surge in wireless communications, the radio industry has seen an increase in the
number of different communication standards each requiring its own specific hardware and
processing. Our project addresses the need for radio interoperability with these various standards
through the development of hardware generators for a software defined radio (SDR) system. These
hardware generators will be created using Chisel, a hardware construction language. When given a
set of parameters or constraints, the hardware generators will automatically output circuit designs
for the given application thereby accelerating the hardware design process and introducing a new
method for multi–standard support. Specifically, our team will focus on the development of
generators for the system's beamforming and MIMO blocks. For this reporting period, our team was
responsible for updating our previous CORDIC block for incorporation in the carrier frequency
offset correction (CFO) block. To refresh, the CORDIC block is simply a set of hardware efficient
algorithms capable of performing hyperbolic and trigonometric calculations without the use of a
hardware multiplier. By avoiding use of hardware multipliers, the CORDIC architecture reduces the
number of logic gates required to perform these trigonometric calculations thereby saving
significant circuit power and area in exchange for less accuracy. The work breakdown for this task is
depicted in the diagram below (see Figure 1). This task

The Security Research Of Cloud Database
The security research of cloud database
Hao Xu
Professor: Carol Auerbach
Course Number: EAP 6110 20
Date: 12/1/2014
1. Introduction
1.1 Background
In September, there was breaking news in the American entertainment world – private pictures of
Hollywood movie star Jennifer Lawrence and other celebrities were leaked online by hacker who
stole the pictures from their Apple's iCloud. People were shocked by this news, and a debate was
generated online on whether cloud technology is safe enough to upload private files. Despite this
incident, cloud database can be trusted as a secure space to store information as long as the users
have some basic safety awareness.
1.2 The concept of cloud database
"Cloud" is a popular concept in the world of technology today. "Put everything in the cloud" is a
popular statement used by cloud database vendors. A cloud database is a database that has been
optimized to create a virtualized computing environment.
Businesses and other organizations with large databases can benefit from putting their databases in
the cloud because it allows them to effectively support and use cloud–enable business applications
as part of a wider software–as–a–service (SaaS) deployment (Rouse, M). Furthermore, more and
more people are choosing to use cloud database to store and share documents, or even run some
software on the web, rather then installing it to their own computer. In addition, cloud database is
also convenient for mobile users.

It was seen with television that minimal archiving was performed and much film has been lost and
scenes from the beginning no longer exist. This can be prevented for videogames by the hardware
being preserved such as the cartridges, tapes, and code that build these games. It is never too late to
start preserving videogames since the materials of the games do start to deteriorate after a couple of
decades possibly even sooner. An emulated machine which allows videogames to be used on
consoles that are not their originals such as the Multiple Arcade Machine Emulator need to be

Essay on Theories addressing learning styles
Theories addressing learning styles
There are several different learning styles and theories about approaching them. Some students learn
better through one or more of the learning styles than another. As Rita Dunn of St. John's University
says, "A students best "modality" for learning may be visual, auditory, or tactile, according to the
speakers"(Walton,1991). An auditory learner may learn better through hearing material spoken. A
visual learner learns better by reading instructions to himself. And finally, a tactile learner will
usually learn most effectively when they are able to use models or things that they can touch or
manipulate. Technology supports these three learning styles; auditory, visual and tactile. Animated

Whether the student learns better through seeing, hearing or a hands on activity, whatever his or her
needs may be, technology is able to assist the student.
How assistive technology addresses special needs
Assistive technology also enhances the skills of students, especially those with certain disabilities.
There are several technological devices used to guide special needs students; particularly those
placed in special education classrooms. These devices are also used by students in mainstream
classrooms. There is such a device used by people who can not speak or write. There are words
programmed into this small tabletop machine which acts as a communication tool for the disabled.
There are large buttons with interchangeable pictures that portray the re–recordable words the
machine plays. These machines are great because they allow those who can not speak on their own
to speak in full sentences by using this. It is uncomfortable enough for special needs students to be
in a regular classroom. Not being able to communicate adds to their frustration. These devices allow
them to participate in a class discussion or to answer questions. There is another device called
AlphaSmart, it is similar in size to a laptop computer. It is a word processor also used by those who
are unable to speak. However, those who aren't special needs students also seem to benefit from
these word processing

Metric 1 : Baseline Defenses Coverage
Metric 1: Baseline Defenses Coverage. This security metric measures how well your organization is
protected against the most common threats. The security tools like Antivirus, Antispyware, and
Firewall should have coverage of 94 to 98 percent for an organization 's security tools to be working
properly, less than 90 percent coverage raises concern. It is best for the organization to run the
baseline defense coverage regularly to see if some of the security tools are slipping or staying up to
par. Metric 2: Password Strength. This metric is perfect for an organization that has a problem with
their password not being difficult enough to break. This system reduces the risk from invasion by
sifting out passwords that are weak and making them harder to break. The result is an organization
that is prepared for potential threats.
Metric 3: Legitimate E–Mail Traffic Analysis. This system takes into account all of the emails
incoming and outgoing. It analyzes the size and content of the email. This system also is very
helpful with determining and preventing unwanted junk mail from coming into an organization. It
also can distinguish if an employee is exposing intellectual property.
Q2:
Do you need to have a disaster recovery plan? If so what might it include?
It is imperative to have a disaster recovery plan, it is no longer safe for any business, small or big, to
have no protection against natural disasters or even getting hacked which is a common practice.

Pros And Cons Of New Media
Old media like cassette tapes are becoming second–tier goods since the public would like to listen to
music through social media feed or visit their favorite music site with a cup of coffee in hand. The
new media technology makes people's lives more convenient in favor of the old ways of consuming
the music types such as social platforms and specific applications. I spend most of my time listening
to music on my smartphone applications whereas my dad spends his time with his old cassette tapes.
In this essay, I will identify the notion of overcoming limits in both physical and social aspects that
new media give us.
Generally, Cassette tapes are a magnetic tool for recording and playback. Over the last decade,
cassette tapes still offer do–it–yourself musicians, who record their original music in tapes and mail
to companies. My dad loves the cassette tapes because he is a rock lover who firmly believes that
the cassette tapes have magic behind it. A lot of the music applications lack a physical, tactile
sensation and collection. However, he sees my music application, which includes all the songs in the
1980s with lyrics and easy to find such as Spotify and Apple Music. For example, one of my dad's
bookshelf is full of the cassette tapes. It is hard to find a specific song or album in short time and to
get tangled up with tape afterward. I just type the name of the song in the search engine, usually is a
blank box at the very top. Then all the relative songs will form a list

Questions On Cloud Computing Fundamentals Essay
2.1 Cloud Computing Fundamentals: Cloud computing is a model for allowing convenient on–
demand access from anywhere to a shared pool of computing resources. These can include servers'
storage, networking, applications, and services that can be rapidly and easily provisioned and
released. The cloud model includes five essential characteristics: On–demand self–service: This
allows users to quickly and automatically get access to the IT resources that they want without
requiring any additional human interaction. Broad network access: This is the ability to access the
service from any standard device that 's connected to the network including PCs laptops mobile
phones or tablets. Resource pooling: Compute networking and storage are pooled and shared across
multiple customers. Rapid elasticity: This allows you to quickly scale or shrink the capabilities of
your cloud to match the level of user demand. Metering: This tracks and controls the level of
resource usage or the cost of that usage. Customers generally choose one of three options for their
cloud deployments either public, private or hybrid cloud. Private cloud: Is provisioned for the
exclusive use of a single organization. The infrastructure is usually owned managed and operated by
the organization within its own firewall. Public cloud: Is an infrastructure that is open for use by the
general public. This type of cloud is owned, managed and operated by a cloud service provider and
runs on the provider 's

Music Industry Research Paper
The music industry has changed in very quickly in so many ways it almost seems impossible.
Thomas Edison recorded the first voice in 1877 and now we listen to hundreds of different types of
music on devices that hold more information than the computers that sent the first astronaut to the
moon. People have been getting music in tons of ways for the past hundred plus years and when the
internet came into the picture, the music industry sky rocketed. People could get their own music out
and be heard just by clicking a few measly buttons and using the internet to stream millions of songs
with high speed. But even though the internet has helped the music industry by making it easier to
distribute, advertise, and produce music, it still has its disadvantages.
Thomas Edison was the first to record sound while he was experimenting with his new telegraphing

Sound Recording In Canada
Sound Recording in Canada, not regulated by the Government
Introduction
Sound recording was initially invented in 1857 by Edouard–Leon Scott de Martinville. The
development of sound recording has gone through multiple stages to become what it is today. From
phonographs to magnetic tapes and further developments, sound recording has been used within the
music industry for ages. The government does not regulate the process of sound recording, however
conflicts regarding copyright infringements are present.

Broadcasting is "$14 billion industry that includes radio and television, as well as the distribution
services of cable, satellite, and, increasingly the Internet and mobile devices" (Gasher, Skinner,
Lorimer 218). The Canadian government regulates broadcasting because "it serves national, cultural,
and political goals" (Gasher, Skinner, Lorimer 219). The reason for comparing regulations between
sound recording and broadcasting is the fact that a great proportion of radio broadcasting is recorded
music. "There is a significant symbiosis between radio broadcast policy and policies designed to
encourage the production and dissemination of Canadian music" (Gasher, Skinenr, Lorimer 225).
Radio broadcasters are required to have a license in order to broadcast music through their channel.
The Canadian Radio–television and Telecommunications Commission (CRTC) is in charge of
issuing these licenses to broadcasters. "Today, the CRTC's duties in the broadcasting field include:
issuing and renewing licenses, up to a maximum of seven years, modifying existing license
conditions, and suspending or revoking licenses" (Gasher, Skinner, Lorimer 221). It is evident that
the use of sound recordings within the field of broadcasting is strictly regulated. This further
develops an idea that the sound recording industry will become regulated within the future, as it is
present in such a vast

Location Doesn't Necessarily Influence Knowledge
Scott Carlson's "For Making the Most of College, It's Still Location, Location, Location" was first
published in The Chronicle of Higher Education on February 4, 2013. Carlson attempts to utilize his
article to illustrate the ongoing (and future) success of traditional universities in contrast to
increasingly popular (and modestly priced) virtual campuses. Early on he mentions an article he
wrote in 2001 about the desertion of libraries in a world of the latest technology and compares how
human interaction and modernization alone could save them both. Carlson clearly states his stance
on the subject after asking whether "campuses and traditional teaching (could) disappear because we
now have MOOCs (massive open online courses)?" After which he answers his own question in the
same paragraph by saying: "No because that defies the human yearning for meaningful places and
the real benefits that come with them. We see it in the migration to cities and in walkable

Generally speaking, the limit is above 200ms, below that duration, loudness is affected by sound's
length. (5)
Direction
The directional perception of sounds in the space is made possible thanks to a subconscious
comparison of the nerve signals coming from both ears (Binaural Effect).
The four factors determining such phenomenon are delay time and intensity difference of the signals
perceived by each ear, together with phase and timbre.
To get into more detail, the delay time, or time of arrival, for each ear, is different whether the sound
source is in front of the listener (0ms of delay between the ears) or next to him or her (up to 0.6 ms),
while the intensity of the signal reaching the closer ear is obviously higher.(6)
The signal perceived by each ear also has a different phase, but only if its bandwidth is greater than

the distance between the ears, I.e. below 500 Hz.
Finally, the timbre is also important, as the signal will lose high frequencies while reaching the
farthest ear.

The Definition Of E Learning
Definition of e–Learning
Today people need to learn new concepts and new techniques that change rapidly, so people have an
overwhelming need to learn, sometime they also need to work while learning and their resources are
limited therefore they need the power of technology to overcome the limitations of time, distance
and resources. E–Learning provide people from one or different organizations anytime and
anywhere learning possibilities, providing the resources to teach them. Different e –
Learning methods exist to support the different learning styles of different people who learn in
different ways and at different times. According to Mindflash.com (2015) "E–Learning is a range of
information technologies that schools and corporations use for education and training." In e–
Learning courses, instructors and students who are too often located in different physical places
receive the information through computer networks, so they are provided the same material via their
computers.
According to Hung Jui–long, (2012), some scholars define e–learning as an instruction delivered by
all electronic media. Among them is Govindasamy (2002, p. 288) who stated that e–learning
"includes instruction delivered via all electronic media including the Internet, intranets, extranets,
satellite broadcasts, audio/video tape, interactive TV, and CD–ROM."
Significant developments in e–Learning over the past ten years
One of the most significant developments in e–learning is the introduction of

Figurative Language In Ray Bradbury's 'The Veldt'
"The Veldt"
As Billy Cox once stated, "Technology should improve your life...Not become your life." This
factual quote also applies to the theme of "The Veldt", by Ray Bradbury. Technology should never
be trusted and this short story very well proves this claim. It highlights the theme of preventing
technology from overtaking the human society, and this is explained by the brilliant use of figurative
language, such as imagery and personification. In "The Veldt," ; the parents own a nursery that
contains a machine. However, their children get attracted to the machine. Subsequently, the parents
attempt to stop the children –before it's too late–. Unfortunately, the children terminate their parents

society. For instance, the house is personified when Peter speaks to it, '"Don't let them do it!' wailed
Peter at the ceiling, as if he was talking to the house,the nursery. 'Don't let Father kill everything.' He
turned to his father. 'Oh, I hate you! 'I wish you were dead!'"(Bradbury) It specifically explains the
behavior Peter has toward his father, simply unacceptable and rude. The cause of Peter acting like a
spoiled brat has to do with technology controlling his mind, plus the extreme addiction of it, thus,
making Peter have a spoiled behavior towards his father. Milne agrees that,"By turning the house
into a living, breathing entity through personification, Bradbury heightens the tension and the threat.
Now the parents are not only fighting their children, they are also pitted against a technological
monster that is working to destroy them:" (Milne).
All in all, Ray Bradbury uses the key concepts of figurative language, such as imagery and
personification to outline the theme. His brilliant usage of imagery and personification shows, and
gives us a better understanding of the theme; to never trust technology, and don't let it overtake
society. It's just like what Bill Cox states about technology; "Technology should improve your
life...Not become your life." If not controlled or stopped, it terminates the human society. (as shown
when Peter and Wendy eliminate

Stephen Wright Technology Summary
"Technology" by H. Stephen Wright is a scholarly article detailing the inefficiencies of technology
dealing with cataloging in libraries. In this article, Wright's main argument surrounds the difficulty
of predicting future technological breakthroughs, specifically in libraries and the music industry. He
continually criticizes and undermines the power that modern technology possesses. He goes on to
find fault in the durability of technology because libraries have to constantly update its collection.
Granted that this article was written more than a decade ago, Wright's criticism still presents a
limited understanding of the possibilities of technological advancements.
Wright introduces the reader to Vannevar Bush's proposed idea of a machine called the "memex"
that allowed scholars to "search a vast repository of scholarly information, take notes, copy
information as needed, and create new scholarship–all with incredible ... Show more content on

In his example, he claims that the computer cannot know that "J.S. Bach" is the same person as
"Johann Sebastian Bach." According to him, "the computer is not necessarily capable of making
these simple deductions." However, the computer, along with the Internet, has continuously evolved
to become increasingly smarter. With the likes of search engines like Google or Yahoo, computers
are able to accurately predict and understand what the end user is attempting to locate. Wright
claims that the music libraries are showing signs of failure with its adaptation in the digital world.
He mentions that music libraries have transitioned to compact discs. His argument is incorrect on
the fact that digital music is the mainstream form of music consumption for the masses nowadays.
However, it does further prove Wright's claim of the difficulty in predicting newer technologies. He
uses an example from astronomer Clifford

The Cloud Security Allience ( Csa )
There are numerous ways one can gain unauthorized access to data maintained in the cloud's data
centers. The methods vary from physical theft to trickery and electronic attack. Common methods of
attack include cracking weak passwords, privilege escalation, exploiting unused database
functionality, targeting known unfixed software vulnerabilities, SQL injection, and stealing
unencrypted back–up tapes (Higgins, 2008).
The Cloud Security Allience (CSA), which promotes best practices for cloud computing security,
cites seven main threats to the cloud: "1) Abuse and nefarious use of cloud computing; 2) Insecure
application programming interfaces; 3) Malicious insiders; 4) Shared technology vulnerabilities; 5)
Data loss or leakages; ... Show more content on Helpwriting.net ...
Accountability refers to determining when a security breach occurs, who was responsible for the
breach, and where to place liability for any losses. Audibility is keeping tracking of who accessed or
changed data and ensuring that employees maintain the minimal access level required for job
success (Yang and Borg, 2012). However, it should be noted that these measures do not physically
prevent subversive actions and rely on the threat of future punishment as a deterrent.
Number four on the CSA list is shared technologies vulnerability. Shared technology vulnerabilities
are possible due to virtualization and multitenancy. Two independent virtual machines could be
operating on the same physical machine, potentially allowing one virtual machine to peek at the
other's data through the physical link (Wiley, 2012). A Denial of Service (DoS) attack can also be
instrumented through multitenancy by misappropriating resources from the shared platform
(Fernandes, 2013). One step that organizations can take to prevent a multitenancy leak is to ensure
the organization's web server is not on the same platform as its database. If someone were able gain
access to a web server that also had a database on it, they would have access to that database. While
this requires more resources to separate the two servers, the additional layer of security is worth the
expense to the organization ("Database Security," n.d.).

Learner Support Challenges
Introduction
Allen (2004) states how learner support can be defined as the resources accessible to learners that
assist them in the process of learning. Power of Charity & Heart is a non–profit organization that
concentrates its efforts on improving the welfare of children. Their mission is met by delivering
distance education to learners in rural communities, underdeveloped countries, and crisis or
emergency zones around the world (Applewhite et al., 2016, p. 2). However, PCH is met by many
challenges. The main challenges consist of: illiteracy rates in some countries, poor infrastructure,
political conflict, and bureaucratic red tape (Applewhite et al., 2016, p. 5). These main challenges
result in inadequate teacher training; limited resources; ... Show more content on Helpwriting.net ...
PCH currently offers services such as: academic tutoring (learning centers and by phone), a learning
management system (Agora), fast track program, a virtual library, and a teacher portal (Applewhite
et al., 2016, p. 5). There are various elements that PCH identifies a need for and that should be put
into place now. Some of these elements are more appropriate for future development. These
elements for future development include: counselling, self–help tutorials and mentoring/advising.
With the growth of distance learning programs, it has been acknowledged that student support
services for distance education students should be similar to the needs of students at traditional
universities. Counselling is a major element that is needed for the students that PCH services. The
goal of counselling is to alleviate the distress, anxiety, and concerns that clients can present
(Richards, 2009, p. 233). Students in these areas are subjected to issues that a typical child in the
United States does not have to deal with. A counselling program for these children allows for them
to have an outlet where they can feel safe. They can express themselves and discuss their

Essay on The Rhetoric of Terror
The Rhetoric of Terror
From the writer: In the wake of September 11, the United States retreated into intense patriotism.
However, love for this country is something more than hanging an American flag outside your
home. True love of America is something more; it is civic virtue, practicing good citizenship. Vote
on Election Day, read the newspaper and write letters to members of Congress. Failing to take
advantage of freedom and democracy may lead to the rise of evil.
From the teacher, Vivian Rice: The events of September 11, 2001, dramatically affected the work in

At the same time, members of the same terrorist group flew a passenger plane into the Pentagon. On
that same day, Osama bin Laden, alleged leader of the Al Qaeda network and mastermind of the
September 11th attack, became something of a new age Hitler. Instantaneously, he became a
household name and later a target of a massive military operation.
Exiled from his native land of Saudi Arabia, Osama bin Laden resides in Afghanistan where he
administers his network of terror. He blames the United States and the West for the struggles of the
Muslim world. His goal is to create a society governed by Islam, free from the corruption of the
West, and the culmination of this dream is to drive the United States and the Jews from the Middle
East. He fights this war not only through terrorist action, but also with the power of language, and
the skills of rhetoric and propaganda to accomplish his goals.
Political scientist Harold Lasswell defines propaganda as "the management of opinions and attitudes
by the direct manipulation of social suggestion rather than by altering other conditions in the
environment or in the organism" (Finch). A propagandist manipulates a situation in the mind of the
subject instead of manipulating the situation itself. The propagandist is a spin doctor, who takes an
idea and makes it appear

In July 2000, Reed Hastings, chairman and CEO of NetFlix.com, Inc., faced a critical decision.
Three months earlier, following one of the worst episodes on record for the NASDAQ market,
NetFlix had submitted its S–1 filing for its initial public offering (IPO).1 As a result of the market
downturn, many Internet companies had been forced to withdraw their IPOs. Investment bankers
indicated to Hastings that NetFlix would need to show positive cash flows within a twelve–month

The NetFlix web site also integrated movies currently showing in theaters by providing the ability to
check local listings and show times, as well as the ability to view movie trailers on its web site. In
addition, the NetFlix web site kept track of each subscriber's preference for various types of movies
and provided an individualized predicted rating for all of the movies on the web site. Since
launching its web site in April 1998, NetFlix had experienced rapid growth. Revenues had grown
from $1.4 million in 1998 to $5.0 million in 1999. The number of full–time employees increased
from 46 in December 1998 to 270 in December 1999. By March 31, 2000, NetFlix had over 120,000
paying subscribers. Typical of most Internet startups, however, NetFlix had not yet earned a profit,
reporting net losses of $11.1 and $29.8 million in 1998 and 1999, respectively. Exhibit 1 and Exhibit

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).

UGC's use of Television for Education
For over two decades University Grants Commission (UGC) of India has been using television for

imported or locally produced, were telecast for the benefit of undergraduate and post graduate
students across the country. The need for using television for higher education was necessitated due

Popularly known as Virtual Classrooms, these terminals enable students, scholars and teachers
across the country share their knowledge and experience. Each day lectures on selected topics,
involving reputed experts, are delivered through EDUSAT. Each lectures is followed by a live
interaction, through two way audio/video, among the participants across the country. UGC has
successfully used the virtual classrooms for conduct of workshops, training programs and online
courses. In addition to the VYAS and the Virtual Classrooms CEC has taken up many serious
initiatives to engage academics, media professionals and multimedia experts in packaging of
knowledge in various forms. These initiatives include: Development of e–Content, Multimedia,
Training of teachers in e–content development, Development of Learning Object Repository (LOR),
Conduct of On–Line Courses using VYAS, EDUSAT and Internet, Production of syllabus oriented

In fact, digital music has been a major contributor to the music industry's revenue increase since its
recent emergence. Subscriptions to online music services and online radios, such as Pandora and
Spotify, have also assisted in raising the industry's overall profits by over $200 million during the
past 5 years (Degusta). Nonetheless, despite the overall transition to digital format, physical music
sales still account for a substantial proportion of industry revenues in major markets. Physical
formats account for more than half of all global revenues, while digital formats now account for
39% of total industry global revenues and a majority of revenues in 3 of the world's top 10 markets
(Smirke). Aside from the aforementioned factors, there are numerous others that are taken into
account when determining the industry's profitability as a whole. Some of the many various revenue
streams include physical format or record sales, digital downloads, performance rights, and
synchronization revenues. While profits from one variable may face a sharp increase, another may
see a major decrease. For example, between 2003 and 2009, U.S. revenue for single downloads
increased by over $1.2 billion and by nearly $0.8 billion for album downloads. On the other hand,
during this 6–year time frame, CD sales in the United States dropped over $1.6 billion and cassette
tape revenues practically reached zero by the end of 2009. Evidently, one of the most vital revenue

even greater revelation because most of these mono mixes have never been heard before on CD and
some of them have actually never been released in any format before (not even vinyl LP!) This box
set does not include Yellow Submarine, Let It Be, or Abbey Road because those final three albums
were only mixed in stereo. These original mono mixes are how many purists believe these songs
were "meant to be heard." And they have a good point! Those mono mixes were the ones that the
band themselves worked on. The stereo mixes were merely an afterthought in comparison. Another
thing that may make this box set a great gift is it's "collectible" status. There may be only limited

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

After the initial outlay for the drive, you'll be faced with the cost of the storage media the drive uses.
Keep in mind that what seems like a bargain may be a moneypit in disguise. For example floppy
disks are still the cheapest per–unit media at approximately 50 cents each, but on a per–megabyte
cost basis (around 35 cents per megabyte), they're the most costly form of storage. Also on the

expensive end of the spectrum are 640 MB, Mag–Optical disks, at about 5.5cents per megabyte, and

Intel And The 8086 Chip
In 1978, Intel came out with the 8086 chip. This chip had 29,000 transistors, 20 address lines, and
could "talk with up to 1MB of RAM ... designers never suspected anyone would ever need more
than 1 MB of RAM" (PCMech, 2001, para. 4). Intel continued to produce its 8000 series chips,
increasing the speed and the memory each time. In 1982, the 286 was the first processor to have
protected mode, which was later used by Windows and other operating systems to allow programs to
run separately but concurrently (PCMech, 2001, para. 8). In the late 1980s, Intel came out with the
386. The 386 was a huge step forward, as it had 275,000 transistors, came in a 33 MHz version,
worked with 4 GB of RAM, and could support a virtual memory of 64 TB (PCMech, 2001, para. 9).
In 2002, hyper–threading came out in the Pentium 4 HT, which meant that the CPU could be fooled
into thinking it had two CPUs for each one that it actually had. Using hyper–threading along with
additional cores has enhanced performance and speed because some cores are utilized for programs
while others perform background jobs (Hoffman, 2014, paras. 6,7). Another way CPUs have been
able to increase speed is by raising the number of cores per CPU socket, and utilizing an I/O Hub
"called QuickPath Interconnect" (Santana, 2014, p. 565). The use of multiprocessing has been the
key for the development of today's CPUs. Memory Memory has undergone many changes over the
years. In 1949, Jay Forrester developed the first
