A definition of a network is:
''Information system implemented with a collection of interconnected nodes''
Computers on a network are sometimes called 'nodes'.
There are many different ways to network computers together. A group of two or more computer
systems linked together. There are many types of computer networks, including:
В· Local–area networks (LANs): The computers are geographically close together (that is, in the
same building).
В· Wide–area networks (WANs): The computers are farther apart and are connected by telephone
lines or radio waves.
WHAT ARE THE BENEFITS FROMNETWORKING?

There are many possible reasons that a company might need or benefit from a network. In order to
understand your particular company, you should start by exploring the following questions. You
may need to ask a variety of people in the company their perspectives on these questions. Some of
the people you may need to interview include the chief executive or the owner, the chief financial
officer, and the key departmental heads within the company, such as manufacturing, retail
operations and so on. The range of people you interview will depend on the type of business (or at
home the users); in this case it is a small and large company.

Improving Network Performance
Nowadays, it seems that everyone has a computer and is discovering that communication
technologies are necessary. E–mail, Internet, and file transferring has become a part of the modern
world. Networks allow people to connect their computers together and to share resources. They allow
people to communicate and interact with each other. The days of the lone PC are diminishing.
At the same time, computers are getting faster than ever. The most powerful PC five years ago
couldn't be sold for half of its original price today. This poses some problems to the consumer.New
technologies can't be driven by older technology. As innovations continue to be invented, the
computer of yesterday is fast outpaced by the...show more content...
Modems, a popular communications device, typically have throughput rates from 9600 baud (See
Glossary) to 28800 baud. Modems use an RS232 or serial port connection.
One solution to this transmission speed is the parallel or Centronics port. This port transmits eight
bits at a time instead of one with a serial port, which is how they got their names. Because it sends
eight bits at a time, a parallel port can achieve transfer rates of up to 40,000 bits or 5000 characters
a second (Seyer 64). Parallel ports are commonly used to connect to printers and external storage
devices.
The main problem with modems and parallel ports is that only two computers can be connected at
one time. Networks were invented to solve this. They allowed a group of computers to
communicate and to share resources such as hard disk space and printers. Different types of
networks have different throughput rates, but all are higher than either serial or parallel ports. The
type of network used at Banks High School is an Ethernet network with software from Novell. This
network has the capability of supporting transfer rates up to ten megabits per second (Bennett 1).
Although this seems like a lot, remember that all of the computers on the network are using this
connection at the same time and each computer has to share with every other computer. There are a
few ways to speed up a slow Ethernet network, however. Splitting the responsibility from one server
to many is one way, and using more than one

Essay on Network
Introduction
"It is certainly safe to say that computers have become as integral to modern life as fast food, cell
phones, and sport utility vehicles". (Joe, 2004) We are living in the information–exchanged age. It
has been dramatically changed since last decades. How could this happen? The answer will be
network. A network can be anything from a simple collection of computers at one location which
have been tied together using a particular connectivity medium (such as network cabling) to a giant
global network, e.g. internet, which uses several different connectivity media, including microwave
and satellite technology. Once, the network is going to falling apart which will be disaster for us.
Thus, we should know what will cause of...show more content...
Sometimes, a disconnected cable or unplugged hub will be causing the problem on the LAN. For
example: network cables have experience disconnection, breaks, shorts and other problems. So,
Joe Habraken (2004) pointed out "physical cabling is always suspected when you are connectivity
problems". Diagnosing these types of problems is done using various tools which is named as
"digital voltmeter". "A voltmeter is an instrument used for measuring the electrical potential
difference between two points in an electric circuit". (Wikipedia, 2011) A digital voltmeter is a
device to test the cable for a break or a short by connecting to a cable. It can tell whether the cable is
bad or not and whether a short or break. If the cable has a break, the cable should be traced to find
where the break has occurred. If there is a short which just replace it.
II.Software
Software can be one of reason which can cause the disconnection in the network. Robert Hudyma and
Deborach I. Fels (Unknown) pointed out: "Network software failures can be caused by faulty device
drivers, subtle differences in protocols implementation and handling and operating system faults and
anomalies". There is some much different software which can cause the disconnection. However, it
is an example will be given. It happens frequently, two computers inadvertently configured with the
same IP address will knock each other off the network. It can be

Essay on Wide Area Networks
Wide Area Networks
The creation of wide area networks links mass communication from people all over the world with
a vast variety of different uses. "A wide area network is telecommunications networks covering a
large geographic area." The internet is the biggest example of a wide area network and has
influenced our daily lives all around the world. Wide area networks are connected to local area
networks to enable computers to share, send, and access information on a larger scale. These recent
technologies over the past 20 years have affected the way we communicate, how businesses operate,
and many other factors that we take for granted. Wide area networks are a fast growing
telecommunications business which are developing new...show more content...
These five types of connections are Point–to–Point Links, Circuit Switching, Packet Switching,
WAN Virtual Circuits, and WAN Dialup Services. "Point
–to–point links provide a single,
pre–established WAN communications path from the customer premises through a carrier network,
such as a telephone company, to a remote network." The lines are designated for this connection
and usually run on leased lines but are typically more expensive than a service which is shared.
Circuit switching enables data connections when the user goes to access another network. Like a
telephone line the connection is linked by a router and when this information is allowed by circuit
switches the router accesses the data transmits a connection. This connection actually makes a call
and connects similar to a phone call. Once the information is translated and sent the user cancels the
connection when they are finished. "Packet switching is a WAN technology in which users share
common carrier resources." Packet switching has carrier networks that allow people with this
feature to share from this network. These carrier networks hold packets of information that can be
accessed by many customers at any time. WAN virtual clients work with a virtual circuit which is a
logical circuit created within a shared network between two

Wireless Networking Essay
Wireless Networking
The term wireless networking is a technology that enables two or more computers to communicate
using standard network protocols without network cabling. The industry standard mainly used for
wireless networking is IEEE (Institute of Electrical and Electronic Engineers) 802.11. What this
standard is could be described as a wireless network with hardware that requires the use of
technology, which deals with radio frequencies as well as data transmission.
There are two kinds of wireless networks, Ad–Hoc (Peer to Peer), or access point (base station).
Ad–Hoc (Peer to Peer) consists of a number of computers each equipped with a wireless networking
interface card. Each computer can communicate to other wireless enabled...show more content...
A software access point does not limit the type or number of network interfaces you use. It is very
flexible in providing access to different network types such as different types of Ethernet, Wireless,
and Token Ring networks.
As mentioned before, software access points can offer more features like Internet access, web
caching or content filtering, which are useful to some users and administrators.
The range of a wireless network is finite. With this limitation overlapping of access points are
needed for seamless use. Use of wireless networking indoors can range from 150 to 300 feet;
outdoor range can be up to 1000 feet (depending on vender of equipment). Other variables of
performance are the environment and building construction. The further you are from an access
point the performance will also degrade.
Multiple access points are needed for roaming building a steady network connection by monitoring
the signal strength from in range access points and locking on to the one with the best quality. The
amount of connections that can use an access point depends on the manufacturer. Some are limited
to ten and other more expensive access point's support up to one hundred connections. Using more
computers than recommended will degrade the performance and reliability of all the connections at
that access point. It is

How to Get Leads on An Event
Are you wondering how you can rock and get leads, the next time you head to a trade show,
conference or even a networking event? This article outlines a couple of pointers to help you on the
same
Whether you are new in an industry or a multi–year veteran, networking events can be valuable tools
for leads generation. It is the best place to get your next client, referral source or even a friend who
might eventually result in new business. However, without a well–thought–out strategy, the time and
resources you invest will not result in quality leads.
Generating event based primes is very simple with a given etiquette and approach. Here are a few
tips on how to get leads on your next networking or marketing event...show more content...
Be more specific and engaging on what you do
A person should be more specific on what one does by asking himself/herself why people they are
connecting with should care about what they are saying. After that craft an engaging conversation
which will create a rapport between the two of you. Also, to be more appealing, use your body
language like nodding to show you are still listening and following which will develop a trust. All
these give you individual control over what happens, and it would not be a wonder if your prospects
ask for contact information next.
Targeted mingling A person should always set a goal to meet 2–5 people and not try associating and
talking to everyone in the event. It is even said that sometimes, one solid connection is plenty. A
pre–planning on whom to meet and talk to should be done. After that a serious research on the
selectively chosen leads should be done before the conference, to ensure that you understand what
they do and get ways in which your business can improve that. Through targeted mingling, one has
higher chances of generating meaningful leads which will build and grow his/her brand
Consider your leads networks
When choosing whom to talk to, always remember that people can help you get leads indirectly from
someone in their network. As you approach and make connections with new people, you should
thoroughly engage with them. You should not leave unfinished conversations just because you have

In the last decade, the number of computers in use has exploded. For quite some time now,
computers have been a crucial element in how we entertain and educate ourselves, and most
importantly, how we do business. It seems obvious in retrospect that a natural result of the explosive
growth in computer use would be an even more explosive (although delayed) growth in the desire
and need for computers to talk with each other. For quite some time, businesses were primarily
interested in sharing data within an office or campus environment, this led to the development of
various protocols suited specifically to this task.
Within the last five years, businesses have begun to need to share data across wide areas. This has

Unfortunately, none of the current solutions scale particularly well. Two general approaches
dominate this area:
1. Virtual Private Networks: When a virtual private network is implemented, the lowest levels of
the TCP/IP protocol are implemented using an existing TCP/IP connection. There are a number
of ways to accomplish this which tradeoff between abstraction and efficiency. The advantage this
gives you in terms of secure data transfer is only a single step further away. Because a VPN gives
you complete control over the physical layer, it is entirely within the network designer's power to
encrypt the connection at the physical (virtual) layer. By doing this, all traffic of any sort over
the VPN will be encrypted, whether it be at the application layer (such as Mail or News) or at the
lowest layers of the stack (IP, ICMP). The primary advantages of VPNs are: they allow private
address space (you can have more machines on a network), and they allow the packet encryption
/translation overhead to be done on dedicated systems, decreasing the load placed on production
machines.
2. Packet Level Encryption: Another approach is to encrypt traffic at a higher layer in the TCP/IP
stack. Several methods exist for the secure authentication and encryption of telnet and rlogin sessions
(Kerberos, S/Key and DESlogin), which are examples of encryption at the highest level of the stack
(the application layer). The advantages to encrypting

Network Design Essay
In designing a network, it is essential to first determine the scope of the project by asking key
questions that will aid in the design and build. Questions such as how many servers and computers
will be connected, what is the intended purpose of the network, and how much money is available
are basic questions that come immediately to mind. Other questions such as security considerations,
and how will the physical architecture of the building affect the design are often ignored but are
equally important to the success of the network. Once these questions have been answered, the
process of network design can begin. As the design of the network affects both media choices and
performance, it is crucial that a design which takes current...show more content...
Category 5 TP cable is rated for speeds up to 100Mbps, operating at 100Mhz, however an
enhancement to this, Category 5e cable, is rated for 1Gbps at the same frequency. The latest
advancements for TP cabling have improved its speed from 100Mbps to 1Gbps. This speed
increase requires the use of a minimum Category 5e rated cable, but is optimized for Category 6
cable, rated at 1Gbps, operating at 200Mhz. Unlike TP cable, Fiber–optic cable does not have
Categories. It is rated at speeds up to 1Gbps and is identified by its type of connection, ST for
Straight Tip, and SC for Straight Connection are two of the most common. Both TP and Fiber–optic
cables are commonly integrated together in a network design. As TP is limited to a maximum
distance of 100m, Fiber–optic cable is typically used as a high–speed backbone, extending the
network to points farther than 100m.
The cost of cabling and ease of installation is an important factor when deciding what types of
cable to run and how long the length of cable will be. By far the easiest and cheapest of the two to
install is TP, and can be used to connect all nodes on the network quickly and fairly inexpensively.
However, Fiber–optic is expensive to install, requiring specialized equipment to ensure correct
termination and is typically used to create a high speed backbone. The design of the network now
includes the layout of the building, the type of cable to be used

INTRODUCTION TO NETWORKING
Abstract
One problem seen with people today is that they are unaware what of a computer network is. They
might have heard of a computer network, but they are clueless as to how it works or why it works.
People have basic questions that need to be answered. The goal of this paper is to give basic
network information that will hopefully answer those questions. To give people an understanding
about computer networks there are several areas that we must discuss. Definitions of some network
nomenclature will be provided. Many people may have heard or seen these words, but never knew
what they meant. Another part that is important is...show more content...
Demand for the services of these large computers increased which meant upgrades had to be made
frequently to keep the processing power ahead of the user need. These systems, called Mainframes,
had been designed to provide computing power, but did not have the flexibility to satisfy the
growing set of applications." (Jones, 2001, Personal Computers History and Development)
Also, in the 1960's the military used networks to communicate to one another. It worked like the
time–sharing network. They needed this network to communicate between cities, bases, and states.
"There was also a concern about a nuclear war. If there was a nuclear war how would people
communicate? There needed to be a network that would be able to work after a nuclear strike. They
came up with a "hot potato network. Basically the information would be tossed like a hot
potato from user to user until it reached its destination. The actual route it took was not important.
This meant that if big parts of the network were destroyed the message would try another route. It
becomes apparent this was not as efficient compared to the traditional telephone system." (Jones,
2001, Personal Computers History and Development)
During the 1970's and 1980's, networking was continuously being upgraded. Businesses, schools,
and the government needed faster networking capabilities to handle all the people that were using
the basic "time–sharing" network. "In 1975, the first personal

1. What is network security?
Network security has changed significantly over the past years. There is more and more data to
monitor and analyze in order to detect the activity of your data and systems. Securing a network has
many variables. Password authentication, network access, patches, anti–virus protection, intrusion
detection, firewall and network monitoring tools are just a few of the things you can do to protect
yourself.
Threats to your network is becoming more complex and it is requiring lots of money, time and
sacrifices to keep up with the growing amount of potential attacks. Companies cannot protect
themselves with just a firewall anymore. Now it's requiring a full security department that...show

It's the same type of the thing, protecting your computer data from getting in the wrong hands.
Who are these wrong hands? The familiar term is hacker which Webster's dictionary describes as
"3: an expert at programming and solving problems with a computer 4: a person who illegally gains
access to and sometimes tampers with information in a computer system". One of the main reasons
for the high level of network security is because of the bad part of the computer hacking world.
2. How to protect yourself? Protecting yourself is only effective if you know what you are
protecting your against and how to protect. There are a couple ways to start getting you more
protected. The first is installing the default operating system. This would have a default
password, no security patches and no virus protection. The second thing you don't want to do is
use simple and common passwords like for example, password. In the 10 immutable laws below,
one of the laws is someone is always trying to guess your password so make sure it's unique. A
third suggestion would be to keep as many ports that you don't need closed and a firewall can do
this which is covered in the 3rd section on Security Technologies. Finally, make sure you don't
click on any email that you don't recognize or looks suspicions. Many viruses get spread by
opening emails or clicking on the link inside. This rule would help decrease the spread
