3.2. Network Topology and Type

Network Topology is the schematic description of a network arrangement, connecting
various nodes (sender and receiver) through lines of connection. Networks can be

arranged in three ways:

• Star topology

• Bus topology All About Cloud
• Ring topology

• Star topology: All computers and devices are connected to a network switch and
this is one of the common topologies nowadays.

• Bus topology: In this arrangement computers and devices are connected to a
single linear cable called a trunk.

• Ring topology: Computers and devices are connected to a closed-loop cable.

3.3. Types of Area Network

The Network allows computers to connect and communicate with different computers

via any medium. LAN, MAN and WAN are the three major types of the network
designed to operate over the area they cover. There are some similarities and

dissimilarities between them. One major difference is the geographical area they
cover, i.e. LAN covers the smallest area; MAN covers an area larger than LAN and

WAN comprises the largest of all.
