What does the acronym LAN stands for?

• Local Arena Network

• Local Area Networking

​Computer Laboratory

There are different types of computer network namely;

LAN (Local Area Network) - A type of computer
network within a specific area or vicinity. For example,
computers inside the school connected to one another
is considered as LAN.

MAN (Metropolitan Area Network) - A type of
computer network within the town or city.

WAN (Wide Area Network) - This type of computer
network is the largest because it it a global
interconnection of computers. An example of this is the
Internet.

Multiple Select

Select the devices that you think can be setup in a computer network.

What are the Equipment, tools and materials
needed in Connecting two computers using

wired connection?

Sherwin C. Maningas

RJ45

RJ means Registered jack. This is a standard physical Network Interface used for
connecting telecommunications equipment commonly, a computer networking
equipment.

UTP CABLE

The cheapest cable use in computer in networking is the UTP (Unshielded
Twisted Pair) cable. Other use the STP (Shielded Twisted Pair) cable which is
cost much than UTP but more reliable.

CRIMPER

Crimping tool is used to join the RJ-45 and RJ-11 connectors to the both ends of
either phone or CAT5 cable.

Sherwin C. Maningas

WIRE STRIPPER

A tool designed to remove the protective covering (jacket)
off of a cable to expose the inner wires. Because different
wires come in different shapes, there are dozens of
different wire strippers available.

LAN TESTER

A cable tester is a
device that is used to
test the strength and
connectivity of a
particular type of cable
or other wired
assemblies.

Interface Card Adapter

Sherwin C. Maningas

Short for Network Interface Card,
the NIC is also referred to as an
Ethernet card and network
adapter. It is an expansion card
that enables a computer to
connect to a network;
