Lesson

COMPUTER NETWORKING
Computer Networking
Many network administrators keep hearing that the network is down because
of some or the other reason. Various researches indicate that in many cases, the
network is down on account of inferior cabling systems. Installing standard
structured cabling systems can eliminate much of this downtime.
A network is two or more computers connected to share resources. In general
term, network can refer to any interconnected group or system. In other words,
network is a method of sharing information between two systems. Computers are
networked according to certain protocols, such as TCP/IP, which are the rules or
standards that allow computers on the network to communicate with one another.

What is It
Types of Network
Networks can be categorized by several methods, including the technology
used and the size of the network. When networks are categorized by size or physical
area they cover, these are the categories used:
1. Personal Area Network (PAN) – consists of personal devices
communicating at close range such as a cell phone and notebook
computer. PANs can use wired connections (such as USB or FireWire)
or wireless connections (such as Bluetooth or infrared). The reach of a
PAN is typically at least about 20-30 feet (approximately 6-9 meters),
but this is expected to increase with technology improvements.
Figure 2: Personal Area Network
2. Local Area Network (LAN) – covers a small local area such as a home,
office, other building, or small group of buildings. LANs can use wired
(most likely Ethernet) or wireless (most likely Wi-Fi, also called 802.11)
technologies. A LAN is used for workstations, servers, printers, and
other devices to communicate and share resources.
Figure 3: Local Area Network
4
3. Wireless LAN (WLAN) – covers a limited geographical area and is
popular in places where networking cables are difficult to install, such
as outdoors, in public places, and in homes that are not wired for
networks. They are also useful in hotel rooms.
Figure 4: Wireless Local Area Network
4. Campus Area Network (CAN) – a computer network made up of an
interconnection of local area networks (LANs) within a limited
geographical area. It can be considered one form of a metropolitan area
network, specific to an academic setting.
Figure 5: Campus Area Network
5. Metropolitan Area Network (MAN) – covers a large campus or city. (A
small MAN is sometimes called a CAN or campus area network.)
Network technologies used can be wireless (most likely LTE or WiMAX)
and/or wired (for example, Ethernet with fiber-optic cabling).
Figure 6: Metropolitan Area Network
5
6. Wide Area Network (WAN) – covers a large geographical area and is
made up of many smaller networks. The best-known WAN is the
Internet. Some technologies used to connect a single computer or LAN
to the Internet include DSL, cable Internet, satellite, cellular WAN, and
fiber optic.
Figure 7: Wide Area Network
7. Global Area Network (GAN) – specification is in development by several
groups, and there is no common definition. In general, however, a GAN
is a model for supporting mobile communications across an arbitrary
number of wireless LANs, satellite coverage areas, etc. The key challenge
in mobile communications is "handing off" the user communications
from one local coverage area to the next. In IEEE Project 802, this
involves a succession of terrestrial WIRELESS local area networks
(WLAN).
Figure 8: Global Area Network
8. Virtual Private Network (VPN) – a computer network in which some of
the links between nodes are carried by open connections or virtual
circuits in some larger network (e.g., the Internet) instead of by physical
wires. The data link layer protocols of the virtual network are said to be
tunneled through the larger network when this is the case. One
common application is secure communications through the public
Internet, but a VPN need not have explicit security features, such as
authentication or content encryption.

Figure 9: Virtual Private Network
Network Topology
The physical arrangement of the connections between computers is called
the network topology or the physical topology.
Types of Network Topology
1. Mesh Network
In a mesh network, each node (a computer or other device that
uses the network) on the network is responsible for sending and
receiving transmissions to any other node to which it wants to
communicate without a central point of communication. When each
node connects to every node on the network, the network is called a
fully connected mesh topology.
Figure 10: Mesh Network
2. Ring Network
In a ring network, nodes form a ring. Really old IBM Token Ring
networks worked by passing a token around the ring. This topology
is seldom used today because one down computer or a broken cable
can halt all communication on the ring.
Figure 11: Ring Network
7
3. Bus Network
Another old topology is a bus network whereby all computers are
connected in a sequential line. The bus network worked better than
a ring network because one down computer does not prevent other
computers from communicating on the bus. However, a broken cable
can still bring down an entire bus network.
Figure 12: Bus Network
4. Star Network
A star network uses a centralized device to manage traffic on the
network. This centralized device can be a switch or hub that offers
multiple network ports or wireless connections. (Hubs are not as
efficient as switches and no longer sold even though you might still
see a hub in use.) Star networks are almost totally used for LANs
today. An advantage of a star network is that one down computer or
one broken cable does not bring down the entire network. When a
star network uses multiple switches in sequence, the switches form
a bus network, and the network topology is called a star bus network
or a hybrid network.

What’s In
For every job there is the right tool. Make sure that you are familiar with the
correct use of each tool and that the correct tool is used for the current task. Skilled
use of tools and software makes the job less difficult and ensures that tasks are
performed properly and safely. Using tools properly helps prevent accidents and
damage to equipment and people.

List of Tools for Networking
Loopback Plug – can be used to test a network cable
or port. To test a port or cable,
connect one end of the cable to a
network port on a computer
or another device, and connect the
loopback plug to the other end of the
cable. If the LED light on the
loopback plug lights up, the cable
and port are good.
Cable Tester – is used to test a cable to find out if it is
good or to find out what type of cable it
is if the cable is not labeled. You can
also use a cable tester to locate the
ends of a network cable in a building.
A cable tester has two components, the
remote and the base.
13
Network Multimeter – is a multifunctional tool that
can test cables, ports, and
network adapters.
Wire Stripper – is used to build your own network
cable or repair a cable. Use the wire
stripper to cut away the plastic jacket
or coating around the wires inside a
twisted-pair cable so that you can
install a connector on the end of the
cable.
Crimper/Crimping Tool – is used to attach a
terminator or connector to
the end of a cable. It
applies force to pinch the
connector to the wires in
the cable to securely make
a solid connection.
Punchdown Tool – also called an impact tool, is used
to punch individual wires in a
network cable into their slots in a
keystone RJ-45 jack that is used
in an RJ-45 wall jack.
