Different types of Topologys

Physical topology's :

1. BUS  Topology
2. STAR  Topology
3. TREE Topology
4. RING  Topology
5. MESH Topology

Bus topology:

  In bus topology all computers attached to a single continues cable that is terminated at both ends 

• A “ T ” connector is inserted in the main cable whenever a station need to connect 
• To avoid the loops and to generating signals we will use terminators at both ends of the cable

Types & Ways of Communications

Types of communications :

1: Simplex communication:  It is a only one way communication.

 Ex: television, radio

Types of network

Types of network:

1. PAN - personal area network
2. CAN - campus area network
3. LAN - local area network
4. MAN - metropolitan area network
5. WAN - wide area network

PAN:

A personal area network is a computer area network used for data transmission among devices such as computers, modems, and printer.

LAN:

A local area network is a computer network that interconnects computers within a limited area such as home, school or organisation within a moderate sized geographical area. The speed of LAN is very fast.
