Networking term means when group of devices are connected to each other.So in computer network,interconnected computers are sharing resources.Resources like text,images,video,audio
,files,documents etc.In computer networking not only computer are connected but I/O devices,terminals are also connected and perform data communication.

What are the elements/components of data communication?

1)Message(content of data).

2)Sender(Devices that send data).
3)Receiver(Devices that receive data).
4)Medium(like wired,wireless etc.).
5)Protocol(set up rule of network).

Need/use/Objective/Advantages of Computer Network:-

1)It provide better communication between hardware and software.

2)Network provide sharing of resources.

3)Many times,error free transmissions are take place.

4)It provide good speed for transmission.

5)Networking is very cost effective.

6)Networking is very flexible. 

7)Video conferencing is also possible.

8)It provide good security.

Disadvantages of computer network:-

1)Sometimes,it may be costly.

2)Required lots of effort on installation.

Type of Computer Network:-

1)LAN:-LAN stands for Local Area Network.It is also called as Limited Area Network(But don't write this full form on your final examination).IN LAN,group of computer are connected to each other with in a building,office,school,home etc.

What is Topology?

Topology is the physical layout of network.It may be in the shape of ring,star,bus etc.

Computer Network devices:-

Some important networking devices are HUB,switch,modem,router,bridge,gateway etc.These devices are used in transmission of data. 

Transmission Media:-

Transmission Media are used to transfer data from one computer to another computer.

It may be of 2 type:-

Guided Media(Twisted Pair Cable,Co-axial cable and Fibre Optic Cable).

2)Unguided Media(Blue tooth,Infrared,satellite etc.).
