Computer Network

1. LAN=Local Area Network is a collection of devices connected together in one physical location, such as a building, office, or home. 

2. WAN=Wide Area Network is a telecommunications network that extends over a large geographic area for the primary purpose of computer networking.

3. CAN=Campus Area Network is computer Network made up Of interconnected of two of more And this is largerthan LANS and smaller than WANs.

4. PAN=Personal Area Network is a computer Network use for communication among various electronic devices such as personal computer and mobile In a close proximity.

5. MAN=Metropolitan Area Network is also collection of Local Area Network Metropolitan Area Network connect computer located in the same geography area such as a coty or town.

6. There are 5 main types Of Computer Network

6.1. LAN

6.2. WAN

6.3. CAN

6.4. PAN

6.5. MAN

7. There are 4 types of Network Topology.

7.1. Star Topology

7.2. Ring Topology

7.3. Bus Topology

7.4. Mesh Topology

8. STAR TOPOLOGY a telecommunications network that extends over a large geographic area for the primary purpose of computer networking.

9. RING TOPOLOGY In a ring topology the nodes are Connected in a closed loop so that each device is connected to two other devices, one on either side. The computer in a ring topology are Conne- cted in the shape of a closed ring.

10. BUS TOPOLOGY In a bus topology All the nodes are Connected to a Single continues Cable called bus. Transmission from Any nade travels the bus in both Direction and can Be received by all The others nodes In the network.The bus has terminators At either ends which Absorb the Single, Removing it from The bus.

11. MESH TOPOLOGY In a mesh topology, All the nodes are Interconnected with One onther which Allow each nodes To have a direct Connection with All other nodes In the network.
