INFORMATION SHEET 2.1-1
Computer Network Concepts
Learning Objectives:
After reading this information sheet, you must be able to:
1. Understand the use of computer networking
2. List the various types of network and network categories
3. Identify the different network hardware used in computer systems and
networks
A computer network is a group of computer systems and other
computing hardware devices that are linked together through
communication channels to facilitate communication and resource-sharing
among a wide range of users. Computers in a network are called nodes. A
connection between computers can be done through cabling most commonly
the internet cable or wirelessly through radio waves.
Networks are used to:
 Facilitate communication via email, video conferencing, instant
messaging, etc.
 Enable multiple users to share a single hardware device like a printer
or scanner
 Enable file sharing across the network
 Allow for the sharing of software or operating programs on remote
systems
 Make information easier to access and maintain among network
users.

A server is the computer on the network that manages the
network resources such as the shared files, programs and printers.
Local Area Network (LAN) is a computer network covering a
small geographic area, like a home, office, or group of buildings.
The majority of networking, particularly at the corporate
level, is done using the internet standard. At the center of the basic
diagram of a wired network is either a hub or a switcher and
computers are connected to the hub, much like spokes of a wheel or
star. Each connection is called a port.
FOUR BASIC NETWORK CATEGORIES
 Personal Area Network (PAN) - it let devices communicate over the
range of a person. A common example is a wireless network that
connects a computer with its peripherals. Almost every computer has
an attached monitor, keyboard, mouse, and printer.
So many new users have a hard time finding the right
cables and plugging them into the right little holes
(even though they are usually color coded) that most
computer vendors offer the option of sending a
technician to the user’s home to do it. To help these
users, some companies got together to design a short-
range wireless network called Bluetooth to connect
these components without wires. The idea is that if
your devices have Bluetooth, then you need no cables.
You just put them down, turn them on, and they
Bluetooth PAN Configuration
 Local Area Network (LAN) – the smallest of the three network types,
consists of PCs connected together within a limited area, such as
within the same building, floor or department. A sample LAN layout is
given below:

 Metropolitan Area Network (MAN) – is a network that spans no more
than 50 miles. It is design to connect LANs spanning a town or city. A
MAN usually spans multiple buildings or even a city. For e.g. a MAN
can connect multiple campuses of the same university spread across
different parts of the city. MAN usually spans an area larger than LAN
but lesser than a MAN.
A sample MAN layout is given below
 Wide Area Network (WAN) – is used to distribute information of miles
among
thousands of users. This also called as Internet. Typically, any
network hop that is larger 10km is classified as a WAN, but this
distance is not very strictly adhered to. Even the last mile link that
connects a home network to a local ISP (Internet Service Provider) is
considered as a WAN link. A WAN is a wired or wireless
telecommunication link that has the capability to carry data over long
distances.
A sample WAN layout is given below:

Network Terms:
 Network Server – is a powerful computer
whose sole purpose is to serve network
clients.
 Host – any computer sharing the same
protocol layer with another computer.
 Peers – any computer whether mainframe,
server or even PC that acts as an information
source on a network.
 Workstation – any network computer that
connects to and request resources from
network.
 Protocol – refers to the specific standards
governing the sending and receiving of data.
Types of Network
 Server / Client Network – use a network
operating system to manage the entire work.
A client server network is one where a client machine requests for a
specific service from a server and the server responds back with the
requested service.
A typical client server message interaction is given in the diagram
below:
 Peer-to-Peer Network – no centralized computer oversees the
networks, no server, and computer simply connect with each other in
a network group to share files, printers, and internet across.

A typical peer-to-peer network message exchange is given
below:
The Basic Rule
The basic rule for network design is known as the 5-4-3 rule. It states that
in a 10mbps Ethernet network:
 You can have a maximum of five cable segments between any two
computers.
 You can have a maximum of four repeaters (hubs, switchers, wireless
access points, etc.) between any two computers.
 Of the five cable segments (maximum) between any computers, only
three of these can terminate in computers.
Network Hardware
 Network Interface Card (NIC) – a printed circuit board, an adapter
that plugs into the computer’s motherboard when connected with a
network cable, provides the physical link between your computer and
the network.
 Network Hub – a hardware that all PCs on a network are connected to
by cabling. The hub manages receiving and transmitting data from
networked services.
 Wireless Hubs - are hubs designed for the home.
o Standalone Hubs – are single products with a number of ports. It is
usually included some method of linking them to other standalone
hubs for network expansion.
o Stackable Hubs – work just like standalone hubs, except that
several of them can be “stacked” (connected) together, usually by
short lengths of cable.
o Modular Hubs – are popular in networks because they are easily
expanded and always management option. It is purchased as chassis,
or card cage, with multiple card slots, each of which accepts a
communication card, or module.

3 Basic Hub Types
 Passive Hubs – simply connects various cables
 Active Hubs – amplify or boost signals
 Intelligent Hubs – select which path a specific signal will
travel
 Repeater – a device that strength signals and allow them to stay clear
over longer distances.
 Network Bridge – divides network into smaller, more manageable
sections helping reduce network traffic.
 Network Switch – it helps determine how data moves over large
networks.
 Router – a device that forwards data packets between Local or Wide
Area Network groups.

Occupational Health and Safety Policy
In the school as a computer teacher you must be aware of
how your students
behave when they are working in the computer laboratory, as well as
implementing a
safe way of accomplishing every task. Safety practices should be learned
early and
always adhered to when working with any electrical device, including
personal
computers and peripherals. This is for the protection of not only the
people working
with them, but also for the devices themselves. The basis for this process
begins with
your Occupational Health and Safety Policies.
Occupational health and safety (OHS) is a planned system of
working to
prevent illness and injury where you work by recognizing hazards and
risks. Health
and safety procedure is the responsibility of all persons in the computer
and
technology industries. You must identify the hazards where you are
working and
decide how dangerous they are. Eliminate the hazard or modify the risk
that it
presents.
Safety Procedure is a common task. It is a general knowledge in our
workplace. In most cases, one must be trained to apply safety procedures in
particular place or in an environment of a certain work, such as factory
where there are heavy machineries, electronics and high voltage facilities.
Safety Procedures may be able to promote a great stability of
a company, to ensure safety of their own products, their facilities and
most especially their personnel during and after work responsibility.
Therefore, itis our goal and responsibility as a worker, in any field of our
skills and even in our great profession, to have these skill and knowledge
for future application in our workplace.

WHAT IS NETWORK COPPER CABLE?
A Network cable is one of the most popular forms of network cable
used on
wired networks. Copper cables connect devices on local area networks such
as PCs, routers and switches.
Unshielded Twisted Pair (UTP) cable
A popular type of cable that consists of
two unshielded wires twisted around each
other. Due to its low cost, UTP cabling is used
extensively for local-area networks (LANs) and
telephone connections.
RJ-45 Registered Jack-4
An eight-wire connector
used commonly to connect computers onto a local-area
networks (LAN), especially Ethernets. RJ-45 connectors
look similar to the ubiquitous RJ-11 connectors
used for connecting telephone equipment, but they are
somewhat wider.

PREPARE NETWORK COPPER CABLE AND TESTING
1.
U
nroll the required length of network cable and add a little extra wire,
just in case. If a boot is to be fitted, do so before stripping away the
sleeve and ensure the boot faces the correct way.

2. Carefully remove the outer jacket of the cable. Be careful when
stripping the jacket as to not nick or cut the internal wiring. One good
way to do this is to cut lengthwise with snips or a knife along the side of
the cable, away from yourself, about an inch toward the open end. This
reduces the risk of nicking the wires' insulation.

Locate the string inside with the wires, or if no string is found, use
the wires themselves to unzip the sheath of the cable by holding the sheath
in one hand and pulling sideways with the string or wire. Cut away the
unzipped sheath and cut the twisted pairs about 1 1/4" (30 mm). You will
notice 8 wires twisted in 4 pairs. Each pair will have one wire of a certain
color and another wire that is white with a colored stripe matching its
partner (this wire is called a tracer).
3.
I
nspect the newly revealed wires for any cuts or scrapes that expose
the copper wire inside. If you have breached the protective sheath of
any wire, you will need to cut the entire segment of wires off and start
over at step one. Exposed copper wire will lead to cross-talk, poor
performance or no connectivity at all. It is important that the jacket for
all network cables remains intact.

4. Untwist the pairs so they will lay flat between your fingers. The white
piece of thread can be cut off even with the jacket and disposed (see
Warnings). For easier handling, cut the wires so that they are 3/4" (19
mm) long from the base of the jacket and even in length.
5.
Arrange the wires based on the wiring specifications you are following.
There are two
methods set by the TIA, 568A, 568B and crossover cable. Which one you
use will depend on what is being connected. A straight-through cable is
used to connect two different-layer devices (e.g. a hub and a PC). Two like
devices normally require a cross-over cable. The difference between the
two is that a straight-through cable has both ends wired identically with
568B, while a cross-over cable has one end wired 568A and the other end
wired 568B. For our demonstration in the following steps, we will use
568B, but the instructions can easily be adapted to 568A.
Put the wires in the following order, from left to right:

6. Press all the wires flat and parallel between your thumb and
forefinger. Verify the colors
have remained in the correct order. Cut the top of the wires even with
one another so that they are 1/2" (12.5 mm) long from the base of the
jacket, as the jacket needs to go into the 8P8C connector by about 1/8",
meaning that you only have a 1/2" of room for the individual cables.
Leaving more than 1/2" untwisted can jeopardize connectivity and
quality. Ensure that the cut leaves the wires even and clean; failure to do
so may cause the wire not to make contact inside the jack and could lead
to wrongly guided cores inside the plug.
7. PP---Keep the wires flat and in order as you push them into the RJ-
45 plug with the flat surface of the plug on top. The white/orange
wire should be on the left if you're looking down at the jack. You can tell
if all the wires made it into the jack and maintain their positions by
looking head-on at the plug. You should be able to see a wire located in
each hole, as seen at the bottom right. You may have to use a little effort
to push the pairs firmly into the plug. The cabling jacket should also
enter the rear of the jack about 1/4" (6 mm) to help secure the cable once
the plug is crimped. You may need to stretch the sleeve to the proper
length. Verify that the sequence is still correct before crimping.

8. Place the wired plug into the crimping tool. Give the handle a firm
squeeze. You should hear a ratcheting noise as you continue. Once you
have completed the crimp, the handle will reset to the open position. To
ensure all pins are set, some prefer to double-crimp by repeating this
step.
9. Repeat all of the above steps with the other end of the cable. The
way you wire the other end (568A or 568B) will depend on whether you're
making a straight through, rollover, or cross-over cable.
10. Test the cable to ensure that it will function in the field. Mis-
wired and
incomplete network cables could lead to headaches down the road. In
addition, with
power-over-Ethernet (PoE) making its way into the marketplace, crossed
wire pairs

could lead to physical damage of computers or phone system equipment,
making it
even more crucial that the pairs are in the correct order. A simple cable
tester can
quickly verify that information for you. Should you not have a network
cable tester
on hand, simply test connectivity pin to pin.

Network Cable Installation
1. Learn how to install prepared network cable.
2. Enumerate the steps in network cable installation
3. Apply the steps in network cable installation
TWO METHODS OF NETWORK CABLE INSTALLATION
Method 1: Router Network
1. Install a Network Interface Card (NIC) per computer you want to
connect.

 A NIC is a like a modem for your computer but it is used for a local
area network (LAN). You do not have to get an expensive network card;
as long as it has 100mbps it will work fine.
 To install it you must first unplug your computer and remove the
cover plate. Align the NIC over the slot that has the jack that is facing
toward the outside of the computer. Put the NIC into the slot and
press down firmly to secure. Replace the cover and unplug the
computer back in.
 Your NIC should come with a disk that will instruct you how to
complete the software installation for the appropriate drivers. Follow
the instructions to finish the installation of the NIC.
2. Connect Network cables to the central location.
 You also need 1 Network patch cable per computer. These Network
cables are blue cables that look like they have phone line plugs at
the end. They will have 4 pairs of plugs rather than 2. Make sure
that the cables that you purchase are long enough to reach from the
central location to the computers. The central location is where all
the cables will go to access the same information and will probably
be where your Internet feed is. The cables will plug into each NIC.
3. Plug all the Network cables to the router.
 A router will make all the computers connected to be part of the
same network. You will need a router that is at least 100mbps. If you

want to be able to access the Internet from all computers, you will
need to have your Internet connection plugged in the router’s uplink
port or WAN port.
Method 2: Hub Network
1. Use a crossover cable to connect two computer’s network
ports.
 In a hub network, to connect two computers that don't have access
to a shared network, you can use a Network cable to make a direct
connection between the two computer's network ports. You are
merely connecting each device to the medium to the main hub via a
crossover cable. Since there is no router involved in this Network
setup, the other computer is not connected to the Internet. It can
share files and documents from the main computer and print from
the same printer.
 Some computers require a special cable called "crossover cable." This
is a specialized cable that is wired in reverse. Ethernet ports have
both inputs and outputs, and the crossover cable is switched so that
the output from one computer connects to the input of the ot
