Information Technology and Application

Notes Disadvantages

1. Not as much security as a LAN
2. If the Hub goes down your network goes down
3. Less reception with a WAN than a LAN

Self Assessment

State whether the following statements are true or false:
6. A local area network is a computer network that covers a broad area i.e., any network whose
communication links cross metropolitan, regional, or national boundaries.
7. CANs stands for campus area networks.
8. WANs are used to connect LANs and other types of networks together so that users and
computers in one location can communicate with users and computers in other locations.

8.4 Summary
A local area network (LAN) is a computer network that connects computers and devices in
a limited geographical area such as home, school, computer laboratory or office building.
ARCNET was developed by Data point Corporation in 1976 and announced in 1977.
A metropolitan area network (MAN) is a computer network that usually spans a city or a
large campus.
A wide area network (WAN) is a computer network that covers a broad area (i.e., any network
whose communications links cross metropolitan, regional, or national boundaries).
WANs are used to connect LANs and other types of networks together, so that users and
computers in one location can communicate with users and computers in other locations

8.5 Keywords

Implementation : It is the realization of an application, or execution of a plan, idea, model, design,
specification, standard, algorithm, or policy. In computer science, an implementation
is a realization of a technical specification or algorithm as a program, software
component, or other computer system through programming and deployment.
Enthusiasm : A strong feeling of excitement or interest.
WAN : A wide area network (WAN) is a telecommunication network that covers a
broad area (i.e., any network that links across metropolitan, regional, or national
boundaries).
LAN : A local area network (LAN) is a computer network that interconnects computers
in a limited area such as a home, school, computer laboratory, or office building.
MAN : A metropolitan area network (MAN) is a computer network that usually spans
a city or a large campus.
