WHAT IS NETWORK?
• A network is a group of two or
more computer systems linked together.
There are many types
of computer networks.

• Local Area Network
• A local-area network (LAN) is
a computer network that spans a relatively
small area. Most LANs are confined to a
single building or group of buildings,
however, one LAN can be connected to
other LANs over any distance via
telephone lines and radio waves
• Its distance is from 0km to 2 km.
Here, Laptops are connected with
host computer .This type of network
is known as LANs.
• METROPOLTIA AREA NETWORK.
• Short for Metropolitan Area Network, a data network
designed for a town or city. In terms of geographic
breadth, MANs are larger than local-area networks
(LANs), but smaller than wide-area networks
(WANs). MANs are usually characterized by very
high-speed connections using fiber optical cable or
other digital media.
• Its distance is about 2km to 50 km.
• WIDE AREA NETWORK.
A computer network that spans a relatively large
geographical area. Typically, a WAN consists of
two or more local-area networks (LANs).
• Computers connected to a wide-area network
are often connected through public networks,
such as the telephone system. They can also be
connected through leased lines or satellites. The
largest WAN in existence is the Internet.
• Its distance is from 50km to infinite.
THIS TYPE OF NETWORK IS KNOWN AS
WANs. Example-OUR INTERNET THROUGH
• HOME AREA NETWORK .
• A HAN is a network contained within a user's
home that connects a person's digital devices,
from multiple computers and their peripheral
devices to telephones, VCRs, televisions, video
games, home security systems, "smart"
appliances, fax machines and other digital
devices that are wired into the network .
• THIS IS TYPE OF LAN .
-CAMPUS AREA NETWORK
-Campus-area network. An interconnection
of local-area networks within a limited
geographical space, such as a school
campus or a military base.
-THIS IS FOR THE BUILDINGS,SCHOOLS
AND COLLEGE CAMPUS.
THIS IS AN EXAMPLE
OF THE CANs. Here
Is the campus where

• TOPOLOGY : The geometric
arrangement of a computer system.
Common topologies include a
bus, star, and ring.
TYPES OF TOPOLOGY?
• THERE ARE SIX TYPES OF TOPOLOGIES.
• Devices are
connected with many
nodes. In a true
mesh topology every
node has a
connection to every
other node in the
• All devices are connected to a central cable,
called the bus or back-bone.
• RING TOPOLOGY : All devices are
connected to one another in the shape of
a closed loop, so that each device is
connected directly to two other devices,
one on either side of it. Ring topologies
are relatively expensive and difficult to
install, but they offer high bandwidth and
can span large distances.
