TLE – ICT – CSS Quarter 4 – Module 1-4:

1

This module covers the knowledge, skills and attitudes on networking, using

tools and LAN cabling. The scope of this module permits it to be used in many

different learning situations. The language used recognizes the diverse vocabulary

level of students. The lessons are arranged to follow the standard sequence of the

course. But the order in which you read them can be changed to correspond with

the textbook you are now using.

The module is divided into four lessons, namely:

• Lesson 1 – Computer Networking

• Lesson 2 – Common Tools for Networking

After going through this module, you are expected to:

• Identify necessary network materials in accordance with established

procedures and check against system requirements.

• Check tools, equipment, and testing devices in accordance with established procedures.

• Install network cables and cable raceways in accordance with established

procedures and installation requirements.

• Follow OHS standards and 5S principles according to enterprise requirements.

• Configuring client device systems.

Lesson

1 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

5

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

6

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

I have learned that ____________________________________________________.

I have realized that ___________________________________________________.

I will apply ___________________________________________________________.

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.

What is It

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.

14

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.
