Computer Information And Networking Career Paper
Computer Information and Networking is a large and growing field that provides those with the appropriate skills and education a wide range of
possible job opportunities. The BYU Idaho catalog has the following to say about careers in Computer Information Technologies: Careers in CIT are
dynamic. New challenges and opportunities await you every day. Working in a team, you will interact cooperatively with the management, customers,
clients, and other information technology professionals to determine what the solution needs to do, what it needs to look like, and how it should
work. One day, you may be meeting with customers and clients, the next designing software, and the next designing a database. The next day you
may be involved in designing a complex network to allow your organization to communicate more effectively using the web, mobile devices, and
computers. The next day you may be setting up a clustered set of web servers. CIT is a very interactive and interesting career in which to work.
(Brigham Young University– Idaho) The focus of this paper is to delve into possible career opportunities that might be available with the skills and
education that I am gaining at BYUI and especially from my CIT 240 networking class. The current curriculum of courses I am taking at BYU–Idaho
are required as part of 2 certificate programs in computer information technology (CIT programming emphasis and CIT web emphasis). Knowing this
fact one would think that I am preparing for an

Telecommunication Structure And Computer Networking...
As Chief Information Officer (CIO) of a small but growing firm, the organization is outgrowing the current architectural centralized telecommunication
structure along with the computer networks. The task at hand is to protect the valuable information, but remain flexible enough for employees to
perform their daily duties. The enhancements need to address security aspects such as remote data access, enterprise mobility, and internal
communications such as email. When accommodating a growing organization, a distributed architecture is more in line with the needs of the future.
Sueur, Deneubourg, & Petit (2012) stated, "Any decision made by an individual is influenced by the relationships he or she has with people in different
circumstances" (p. e32566). By analyzing the organization 's telecommunication structure and computer networking security measures, we can evaluate
the strengths and weakness of the centralized and distributed architecture and determine which will be the best approach for the growing organization.
To determine which may be the better architectural fit, first, let's explain the differences between the two options that may support the goals of the
organization. In a centralized organizational structure, the decision–making falls on only one person to make those decisions for the company along
with providing direction for the enterprise. A centralized structure is mostly used for small business because the owner of the company usually has the

Computer Operating And Networking Systems
Identify the computer operating and networking systems used in the company
We are using windows 7 and 8 on all PC for our company, 2003 network servers. It comes a time for change and IPv6 is it, so we have to be prepared
for it. Our company has about 100 personnel who needs network access. If we are in need more IP's or the company grows, we might be in trouble.
We need to quickly change to the latest version, from IPv4 to IPv6 in order to keep the network and company in a place for future growth. IPv6 has
been around since about 1995, and some companies have been testing it, it is installed on the unit, and enabled by default, but most people have not
activated it. Windows 7 and 8 and servers 2003 all are ready for upgrade to the IPv6 network setting. As we know IPv4 only give you 4 billion some
user and are completed, the new version IPv6 has an unlimited number of addresses to use, with hope of not running out.
The pros and cons of IPv6 over the use of IPv4 IPv6 are better security, since the security for IPSEC is built into IPv6 upgrade; more available IP
address, since we are switching from a 32 bit system to a 128 bit protocol; IP address can be close to an unlimited number and should not run out,
but as with IPv4, it could happen; better and faster service for video screaming, games, and video conferencing since the UDP will work much better
for screaming of video quality of services; and an auto configuration of all router on the system and it has a larger

Computer Networking and Communication
A computer networking and data network is a telecommunication network that allows the computers on a network may be linked through cables,
telephone lines, radio waves, satellites, or infrared light beams. This facilitates communication and resources sharing within huge amount of people in
deferent location. Best known as Internet, is the computer network established using either cable media or wireless media. The only system been used
before 19th century was postal system, and it would take several days depending distance between sender and the receiver. But now a day by the
access of Internet you can communicate with people within seconds, and doesn't matter where they live or the distance between sender and receiver.

But using this entire social network human is becoming less emotional and sometimes your life cannot be private anymore. Advance technologies
and networking are leading us to lack of job in society. Before we used to see a person called "postman" but now a day we no longer use this postal
system. Now a day in countries like United State people use online shopping, and the reason often obtain by people is because online shopping
saves them time and money. They find more offers online, but as a result there are less shops and less shop means less people working in those
shops. Internet and computers are considering being addictive, same as alcohol and drugs. Internet addiction is a huge problem facing our world
right now, specially in countries like South Korea, where over 210,000 children are internet addicted who spends up to 18 hours a day on the
internet. According to Professor Susan Greenfield of Oxford University "christened this 'infantalisation' or childlike behavior due to a lack of social
skills. The reduced social interaction that occurs due to increased use of communications technology can result in a lack of social learning. Common
courtesy such as tact, politeness and listening skills may become obsolete". For students, Internet is the best way to conduct their research or
homework. Doesn't matter the topic it will be in the palm of your hand just by one click. But there are lots of consequences of

Research Projects Assessment Task 1: Data communication types historically used, developments leading to Local Area Network, current data
communication, and trends from emerging developments. Communication among humans has always been there from the very start and the modes of
communication developed as they moved further apart from each other. The early centuries records of people messengers who were used to transport
messages as fast as they could. Pigeons were trained to transport messages. There is indications that Heliographs were used for serious signaling
purposes. A code book was issued by the 16th century for British navy including flags with different meanings to communicate during the war. Then
there were watchman who had the responsibility of data transmission. There were various ways of transmitting data without the help of electricity
(Holzmann and Pehrson, 2015).
The age of electric telegraphed information came into picture in the late 1800's when the first Trans–Atlantic cable was laid. The basic elements of
Morse code were used. "Mr. Watson, come here, I want you." These were the first words spoken by Alexander Graham Bell while working with his
invention, the telephone. The wireless telegraph was a major breakthrough in the development of broadcast communication (Holzmann and Pehrson,
2015).
The turn of the nineteenth century saw the invention of tele typewriter. Tele printer

The Importance Of Making Valid Decision And Strategizing...
1
I still remember the days in my universities as if it were yesterday. In those days I worked with lot of national and international organizations, which
are working in varied sectors and bringing change by modern methodologies. In second year of my under–graduate, I founded a Non–Governmental
Organization named Fep–Si (Forum for Empowering people through Social Innovation and Entertainment) and worked with another organization
named Alexis Foundation as research associate for designing public policy driven by Big–Data. From the experiences of working in these
organizations I learnt about the importance of making valid decision and strategizing on business, polity and market front by providing accurate and
up–to–date information and performing data–driven decision making at minor level. On the other hand exposure of working with United Nations
Envoy on Youth also helped me in evolving as a leader who has the quality of thinking analytically towards global problems. During these days I have
felt many times that a lot of these problems can be solved by integrating computer technology into data collection and management of resources, energy,
capital and various other things which are generally done by old methodologies. These instances motivated me to believe that in the complex and
interconnected world of international business and its strategizing, the science of information management is ever more important.
My interest in analytical thinking and science dates back to my

Computer Networking
INTRODUCTION
Computer networking is the engineering discipline concerned with the communication between computer systems or devices. A computer network is
any set of computers or devices connected to each other with the ability to exchange data. It is sometimes considered a sub–discipline of
telecommunications, computer science, information technology and computer engineering since it relies heavily upon the theoretical and practical
application of these scientific and engineering disciplines. There are three types of networks namely: Internet, intranet, and extranet.
A computer network, often simply referred to as a network, is a collection of computers and devices connected by communications channels that
facilitates ... Show more content on Helpwriting.net ...
The major characteristics of LANs, include their higher data transfer rates, smaller geographic range, and no need for leased telecommunication lines.
Current Ethernet or other IEEE 802.3 LAN technologies operate at speeds up to 10Gb. This is the data transfer rate. IEEE has projects investigating
the standardization of 40 and 100Gb.
Wide area network
A wide area network (WAN) is a computer network that covers a large geographic area such as a city, country, or spans even intercontinental distances,
using a communications channel that combines many types of media such as telephone lines, cables, and air waves. It usually uses transmission
facilities provided by common carriers, such as telephone companies. WAN technologies generally function at the lower three layers of the OSI
reference model: the physical layer, the data link layer, and the network layer.
The Internet is considered the largest network in the world. The PSTN (Public Switched Telephone Network) also is an extremely large network that is
converging to use Internet technologies, although not necessarily through the public Internet.
A Wide Area Network involves communication through the use of a wide range of different technologies. These technologies include Point

Wireless Technology Essay
Wireless technology has become the wave of the future. From cellular phones to wireless point of sale devices, wireless networks and technology is all
around us. In order to jump on the wireless train, one must first understand the different standards. To properly and safely utilize wireless technology
the user also must understand the various types of wireless security. Once grasping these technologies and standards, anyone can implement a wireless
network in their home. First, the 802.11b wireless networking standard, which is the most common consumer based standard. The 802.11b standard's
frequency is in the 2.4 GHz range which is common with most cordless land line telephones and some microwave ovens. There are not really many ...

An upgrade to 802.11b is 802.11g which offers some of the same technology as 802.11b but with significant upgrades and improvements. The most
significant improvement over the 802.11b standard is the speed. 802.11g supports speeds upwards of 55mbps which is a huge increase over the
11mbps of 802.11b. This standard operates at 2.4 GHz which is the same frequency that the 802.11b standard operates at. Another great thing
about the 802.11g technology is it is backwards compatible with a 802.11b wireless card so there is no need to go out and buy a new wireless
network card for your computers. Finally a brand new standard that is still in its infancy stages and still has yet to be ratified by the IEEE is
802.11n. 802.11n will be a huge step towards equality amongst wireless and wired networks. First, the standard sets a speed requirement of at least
100mbps which is common amongst most wired computer networks. It is most likely that the throughput will be in the 200mbps range with a
maximum being set in the 600mbps range. Looks like the 802.11n standard will be operating at both 2.4 GHz and 5 GHz frequencies. Look for the
final 802.11n draft out in April of 2009. After choosing a particular standard to go with and buying the equipment to support that standard, one need to
know the method of security they wish to implement on their

Another helpful piece of advice that Vakil noted was, when using Internet browser windows, to check the address line to see if the "http" is
replaced with "https" and to look for a small padlock in the status bar at the bottom of the browser window (Vakil, 2005). This will tell you if the web

site you are accessing is secure. It is also recommended that a consumer use a personal firewall and the most up–to–date virus protection software
(Breeding, 2005). Based on my research I concluded that if consumers use the most up–to–date and secure wireless network protection, they can
connect to their wireless network and conduct business safely and confidently.

II.OBSTACLES IN WIRELESS SENSOR SECURITY
Wireless sensor nodes[2] have limited resources such as limited memory and limited power. There is unreliable communication in wireless sensor
network that leads to threat to sensor security. The security of network depend on communication which relies on protocol.
Energy Constraint: Energy requires converting input to output (sensor transducer), communication among the sensor nodes and computation. Security
levels depend upon the cost of energy.
Memory Limitations: Sensor nodes have small amount of memory and storage. Sensor nodes require simple algo–rithms because they do not have
enough space to store complicated algorithms and executed them.
Unreliable communication: – Unreliable communication occurs due to unreliable transfer, conflict and latency. Unreliable communication occurs due
to connectionless packet based routing in wireless sensor network. Even if channel is

Wireless technologies in the Oilfield
Introduction
In this research paper I will be exploring the new digital oilfield. This is defined by Sidney Hill of plantengineering.com as "an oilfield that harnesses
information technology in ways that allow an oil company to capture and analyze data about all of its operations, ideally in real time, thus maximizing
production while minimizing costs."[1] I will cover why this technology has been brought in, what benefits it brings with it, how they are using it, and
the possible threats that are holding it back.
According to the International Energy Agency, the United States is looking to become the world's top producer of oil by 2017, a net exporter of the
fuel by 2030 and possibly self–sufficient by 2035.[2] This shows how big the oil industry has become and how much more it could grow. Over the
past several years the United States has seen in explosion of exploration and new drilling operations being started in remote and geographically
challenging areas where communication options are limited. Due to this, many oil companies are looking into the advantages of using wireless
technologies to improve their profitability, both in these new projects and in their existing operations. With the understanding that 75% of oil
companies having wireless networks in place, Vodafone Global Enterprises, a worldwide telecommunications company, teamed up with equipment
maker Huawei to conduct a survey with over 100 oil and gas leaders to gauge

Categories for The MAC Protocols for Wireless Sensor Networks
The MAC Protocols for wireless sensor networks are divided into two categories:
1.Contention–based: The Contention based protocols are used to avoid the hidden terminal problem. But the problems with these are idle listening,
collision avoidance, and overhearing. IEEE 802.11, S–MAC are examples of this category
2.Reservation–based: TDMA protocols are based on reservation and scheduling. They have less energy–consumption compared to Contention based
Protocols. Bluetooth is an example of TDMA based protocol
A.IEEE 802.11 Distributed Coordination Function
IEEE 802.11(DCF) is widely used contention–based protocol in wireless sensor networks. The DCF is a random channel–access scheme where every
station begins its transmission based on ... Show more content on Helpwriting.net ...
Besides there is possibility of re–transmission of collided packets
The above three reasons are major sources for energy–wastage in conventional protocols They are avoided in Sensor MAC using two techniques:
Periodic Sleeping and Adaptive Listening
Periodic Sleeping:–
Node must first listen to their neighboring nodes before starting their own listen and sleep schedules .There are two options for the Sensor Node
1.If the sensor node listens the schedule of any of the neighboring node ,then it becomes follower
2.If the sensor node doesn't listen to any schedule from the neighboring nodes then it frames its own schedule and becomes Synchronizer. It broadcasts
its own schedule
If the nodes don't aware of each other, Periodic Neighboring node discovery solves the problem Advantages
Due to Periodic Sleeping there is Reduction in Energy Consumption
Disadvantages
Due to periodic sleeping increase in latency occurs
Adaptive Listening:–
Adaptive Listening reduces the delay caused by Periodic Sleeping. In this technique, if the node overhears its neighbor's transmission, it wakes up at
the end of transmission for a short period of time. if

Wireless Fidelity
In the last few years the world has undergone a tremendous and unprecedented technological change with the attack of the Information Technology
revolution. Earlier it was e–mail that changed the way people communicate, and then online shopping became the order of the day, gradually online
banking caught up and the list goes on and on. The new trend, Wi–Fi, or Wireless Fidelity, allows you to connect to the Internet from your couch at
home, a bed in a hotel room or at school, all without wires. As author Harold Davis nicely puts, "Wi–Fi is a wireless technology just like a mobile

IEEE 802.11b defines the physical layer and media access control (MAC) sublayer for communications across a shared, wireless local area network
(WLAN). As Theodore Rappaport states, "At the physical layer, IEEE 802.11b operates at the radio frequency of 2.45 gigahertz (GHz) with a
maximum bit rate of 11 Mbps. It uses the direct sequence spread spectrum (DSSS) transmission technique. At the MAC sublayer of the Data Link
layer, 802.11b uses the carrier sense multiple access with collision avoidance (CSMA/CA) media access control (MAC) protocol" (35). A wireless
station with a frame to transmit first listens on the wireless medium to determine if another station is currently transmitting (this is the carrier sense
portion of CSMA/CA). If the medium is being used, the wireless station calculates a random backoff delay. Only after the random backoff delay
elapses can the wireless station again listen for a transmitting station. By instituting a random backoff delay, multiple stations that are waiting to
transmit do not end up trying to transmit at the same time (this is the collision avoidance portion of CSMA/CA).
Collisions can occur and, unlike with Ethernet, they might not be detected by the transmitting nodes. Therefore, 802.11b uses a Request to Send (RTS)
/Clear to Send (CTS) protocol with an Acknowledgment (ACK) signal to ensure that a frame is successfully transmitted and received.
The 802.11b

Computer Networks And The Network
A computer network is any computer or group of computers that are linked to another computer or systems of computers so they can communicate.
There are several careers that involve knowledge of computer networking. Each of these positions require a particular set of skills. While the positions
may sound the same, they are not. For example, the network engineer manages and designs computer networks, upgrading them and tests their security
while the network administrator keeps the network running. The network analyst is responsible for supporting the overall infrastructure of the computer
network, writing software and other programs that are needed. The information systems administrator is responsible for designing, delivering, and
maintaining the infrastructure that makes up the network, usually in an organization. The network technician is the one who sets up the network,
troubleshoots problems and services the network to keep it running. The network information systems manager is responsible for the technicians,
administrators, analysists and engineers while also planning for the network into the future (Computer Networking Majors Guide).
The career that I would choose, at least for now, would be a network technician because I like to build things and enjoy the hardware side of

State Of Statement Of Purpose For Computer Science
Statement of Purpose
[Purpose]
During my under graduation, I nurtured an idea to shape my career in the way of doing research, in which period of time, has turned into my career
goal. I am convinced that I should pursue a career in research and teaching as my profession. I wasn't quite sure of what area of research I should get
involved in, since I was interested in multiple areas of study until my high school. Taking a multi disciplinary undergraduate major has helped me to
realize that computer science and logic are the areas which fascinates me the most when compared to others. By the end of under graduation I am
crystal clear and confident in setting my priorities over computer science. Research at PhD level would be the best bet to satisfy my long term goal. I
opine that completing masters and doing research at masters level would qualify me with the required skills in computer science and would set a
perfect platform for my entry into PhD. Thus, after a careful consideration of my interests, abilities & goals, I decided to pursue masters degree in the
field of Computer Science. [My Background]
Since childhood I always excelled at quantitative and logical abilities. Thus, I had a strong inclination for mathematics and physics. This led me to opt
for mathematics, physics and chemistry as my majors at higher secondary level (10+2). After completing high school with outstanding grades, I was
interested in pursuing my further studies ... Show more content on Helpwriting.net ...
I feel that I need much more enhanced knowledge. Infact, I am more interested in doing research. In the next five years I hope to complete PhD with
intense research experience. I have a strong passion for teaching which may lead me to take the path of teaching after PhD. But my immediate short
term goal is to complete masters with good grades and with research which would be a learning

Although I mentioned a 1 terabyte SSD, they're somewhat rare. Typically you'll find SSD's sized from 128 to 512 gigabytes. These lower sized
drives aren't sufficient for organizations or individual users who store photos, music, and video content locally. Therefore, the lack of storage
space, and lack of availability make the traditional HDDs more attractive as they are certainly more plentiful (Domingo, 2014). Recommendation
or not for consideration of SSDs. The Delaware Health and Social Services is running a risk of pushing its existing system to the limit because of
health care legislation. It would be better for this government agency to proceed with upgrading to SSD drives in place of the 15,000 rpm drives.
The agency is involved in a great deal more of SQL databases and the use of an SSD offers significance performance over traditional drives. As for
the Disabled American Veterans nonprofit organization, they're already using the technology on a smaller and have a very good sense of how it can
benefit the organization. They should continually monitor the cost of flash technology and if it continues to fall in price, they should consider getting
a preapproved budget so it will already be in place by the time their next upgrade is due. Both organizations clearly see the benefit of the newer
technology, but cost is a factor. However, the benefits should be taken into consideration and in time the initial cost can be

INTRODUCTION OF LAN
LAN known as a local area network is a computer network that connected computer within a small area such as a school, collages, a hospitals and an
office building using network media. In contrast to wide area network (WAN) this covers the huge area. In LAN, there is a main computer called
server and distance computers called clients. With the help of LAN users can access internet, can exchange file with connected users, and also can
communication between users via electronic mails and others applications.
MANAGEMENT OF ACCESS TO A LAN
The resources on a local area computer network needs to be managed for their efficient use and maintenance. They include local computers, printers,
telephones, routers/internet access etc. To manage this resource a system administrator/Network administrator can use multiple management software
like active directory authentications, User and group policies, physically restricted access to devices etc.
RESOURCES WHOES ACCESS CAN BE MANAGED

Computer Networking is Revolutionizing Our Society
The Internet, a combination of technology, communication, and media, is a developing and unique medium in its infancy. Technology and tools of
communication are still in the process of development as technology continues to advance. As a site of cultural, political, and ideological discussion, it
has unquestionably contributed to a culture and lifestyle dependent on technology. The World Wide Web has reconfigured people's perception of the
world, allowing access to an extensive amount of information that previously has been inaccessible to them. In addition to enabling users to gain access
to a plethora of information, the Internet is a tool of globalization in which ideas, knowledge, and thoughts are instantaneously shared on a worldwide
scale. While some have portrayed the Internet as a powerful tool for free expression on the global network, others have highlighted the potential of
networks with which the government can constrain the power of organizations through collective online actions and surveillance. With increasing
advancements in technology comes greater and easier access to information and control. In a democratic nation, the Internet's ability to facilitate access
to information about another person violates privacy rights. With the Internet, existing laws are ambiguous about what standards apply for different
kinds of surveillance. Computer networking is revolutionizing our society in an affirmative way. Technological advances like the Internet facilitates

Wireless Network
Introduction Wireless network is indicated to a telecommunication network whose interconnections between nodes are implemented without the use of
wires, such a computer network. Nowadays, wireless network has become the important thing in telecommunication. This sort of technology has been
used for over a century and remains synonymous with radio. In 19th century, Guglielmo Marconi invented a radio and made his made his mark in the
world of wireless technology. At that moment, Marconi was about to produce detect radio waves from long distance. In 1896, the Wireless Telegraph
and Signal Company Limited was established and became the first radio actor in the world. The first wireless signal was sent using Morse Code.

802.11a distribute a range of approximately 33 meters or about 100 feet. This standard uses much frequency and high frequencies have their
limitations. It does not break through the walls as good as lower frequencies and they require need more energy to power the devices. The clarity of
signal is normally good and less interference than the other 802.11 standards. The cost for 802.11a is more expensive than both 802.11b and 802.11g.
However, it is very worth because it provides the great speed. 802.11a is not compatible with other types of standard. The users have to have theWi–Fi
card to receive the 802.11a signals.
2.802.11b
802.11b is the type of standard that is less expensive, faster, and easier to use than the other kind of standard. This technology includes a wireless
router that is able to send radio signals over the air to other computers or electronic devices. Generally, Wi–Fi router is connected to computer server or
broadband internet connection. 802.11b can distribute speeds up to 11 mega bytes per second. This standard delivers a signal for about 50 meters
(150 feet). The range depends on the area and condition whether you are in an apartment building, having your router on another floor than your
computer or being in open area. 802.11b has the good signal because it has the lower frequencies, so it will be able to move through the walls and
other obstacle. The cost expended for this technology is affordable.

Queuing delay and packet loss. Many packets can arrive at a packet switch roughly at the same time. If these packets need to be forwarded on the
same outbound link, all but one will have to "queue," that is, wait to be transmitted. This waiting introduces a queuing delay. Furthermore, if the
queue of packets becomes very large, the packet switch's buffer may become exhausted, causing packets to be dropped or "lost." Queuing delay and
packet loss can severely impact the performance of an application. Protocol layers. A typical computer network makes use of many protocols–easily
hundreds. To deal with this complexity, the protocols are organized into layers. These protocol layers are arranged in a "stack." For example, the
Internet organizes its protocols into five layers–namely, from top to bottom: application layer, transport layer, network layer, link layer, and physical
layer. The protocols of layer n use the services provided by the protocols at the layer n– 1 (the layer below). This abstract concept, 4 STUDY

HOME AREA NETWORK
A Home Area Network is an interconnection in which some networking devices are connected with each other for sharing resources between them with
the help of internet. The main advantage of Home Area Network is that you can share different type of content i.e. videos, audios etc. among
different users. A computer with large storage memory can be used as server which can be easily accessed by the clients and users can easily access
the data whenever they wanted to access. As in Home Area Network everything i.e. Resources, Data, Information etc. is shared so each user can use
devices like Printers, Scanners which will be very cheap. Also another main advantage of Home Area Network is that there is no need to buy several
different Public IP Address's for different devices, administrator of network can only have single Public IP Address and assign this public IP address to
a modem or a router, while a modem or a router in turn assigns a private IP address to each device to access the internet.
Many people are turning to their home computers for both work and entertainment. Some companies

Computer Networks And The Network
Computer Network Careers A computer network is any computer or group of computers that are linked to another computer or systems of computers
so they can communicate. There are several careers that involve knowledge of computer networking. Each of these positions require a particular set of
skills. While the positions may sound the same, they are not. For example, the network engineer manages and designs computer networks, upgrading
them and tests their security while the network administrator keeps the network running. The network analyst is responsible for supporting the overall
infrastructure of the computer network, writing software and other programs that are needed. The information systems administrator is responsible for
designing, delivering, and maintaining the infrastructure that makes up the network, usually in an organization. The network technician is the one who
sets up the network, troubleshoots problems and services the network to keep it running. The network information systems manager is responsible for
the technicians, administrators, analysists and engineers while also planning for the network into the future (Computer Networking Majors Guide). The
career that I would choose, at least for now, would be a network technician because I like to build things and enjoy the hardware side of computing.
There are several skill sets that I need to perform this job. One of the required duties is to set up the network hardware that the business needs. This

Abstract– In this paper data aggregation using multipath routing is proposed. In existing system, under hybrid scheme, it each sensor nodes generates
information by sensing its physical environment and transmit to sink by multi hop communication. In network aggregation computation intermediate
forwarding nodes can substantially increase the network life time but amount of data contained in single packet and make the system vulnerability to
packet loss. Instead of retransmission it takes the additional time. Multi path routing multipath multi speed routing protocol is used to improving the
performance of data aggregation due to avoiding these problems.

As many companies have such high expectations with regards to value, they really are simply not attractive prospects for public consideration. The end
result is, the tech–firms that would benefit the most and have a cash flow, are removed from the opportunity. One reason behind the trillion–dollar
volume in activities from mergers in 2013 is the premise that investors demanded more profits, hedge funds and wealth fund investors are bringing
large sums of ready cash assets to the table to invest in these joint ventures.
Another contrasting difference in the subject research is the impact the environmental conditions have with respect to the high–technology mergers.
Despite the variety in strategies among the various high–tech companies, one would expect merges would be straight forward. However, that is not the
case in many of these partnerships. Actually the merger often reveals many alternatives once the engagement happens. Why is it important to
understand the environment in which these pre–merger prospects exist? Technology strategies are very complex to execute and almost always involve
cultural and organizational change (Bettis & Hitt, 1995).

Abstract: In wireless sensor network, sensor nodes have limited power back–up. So, the main issue is to increase the network lifetime. The multi–chain
concept in PEGASIS and sink mobility increases the network lifetime in wireless sensor network. In this research paper, we have proposed a revised
multi–chain PEGASIS protocol by revising the position of the mobile sink to maximize the network lifetime. The simulation is done in MATLAB
R2008a and results are compared with MIEEPB (Mobile sink improved energy–efficient PEGASIS–based routing protocol). Also, we have simulated
revised multi–chain PEGASIS according to standard assumptions and results are shown satisfactory.

Cybersecurity Computer technology and networking have wide ranges of needs to keep it secured while providing fast service to its users. One way
this can be done is through cybersecurity, the protection of information by using technologies and processes to defend a computer or network from
attacks and unauthorized access. Many people don't exercise enough cyber protection and get security problems in multiple ways. There are the more
well–known hacking attempts where people get into other's accounts and steal information or, sometimes, money. There are also attacks that aren't
easily identified, like phishing emails that lure people to click links or send personal information with fake emails. There are many different types of
attacks that could harm individuals and businesses, but there are techniques used in cybersecurity that help to prevent and stop those assaults. An
example of an older, outdated approach is Wired Equivalent Privacy, or WEP, which is an encryption technology ratified in 1997 that is now easily
hackable. Newer technologies are coming out that can improve protection procedures and create a safer world. However, there are also methods and
hardware that are becoming popular that make it easier for cyber criminals to attack others and cause harm. Some newer technologies that are impacting
cybersecurity in many ways are artificial Intelligence, deception technologies, Graphics Processing Units, and quantum computing. Artificial

Introduction
As wireless technology has begun to mature, the demand for wireless products has increased as new applications for the technology are realized. One
application for wireless technology at the U.S. Naval Academy is to use the wireless capability to enhance classroom instruction. Currently the
Electrical Engineering and Physics Departments have wireless access points and wireless laptops/desktops available for classroom instruction. The
purpose of this report is to provide the technical research necessary to aid decision makers in determining which wireless technologies the Naval
Academy should invest.
Background
In a wireless network, computers communicate with the network through a radio ... Show more content on Helpwriting.net ...
Each access point can practically service between 32 to 64 users, depending upon manufacturer. The bandwidth will be shared by all users. The
number of radio channels associated with each technology will vary by technology and product manufacturer. Multiple channels allows for multiple
access points to be collocated in order to provide access for a larger number of users.
Current USNA Uses
The Electrical Engineering Department currently uses the Dell suite with a wireless access point and 24 wireless laptops. They use the wireless
network for "in class" projects where the use of either simulation (OPNET) or design software (PSPICE) is being taught and used.
The Physics department is using a LinkSys 802.11b wireless access point and LinkSys wireless NIC cards with desktop computers. Their primary use
is for internet access.
Recommendation

The best technology system for the Naval Academy would be the 802.11a standard. It has 54 Mbps throughput capability as well as adequate range,
sufficient for classroom use. Since the 54 Mbps is shared amongst all users, it would allow, at a minimum, 2 Mbps for each user in a class of 20
midshipmen operating simultaneously. It also has higher data rates at comparable distances
