Computer Network Introduction
- When data transmission(Audio/Video/Files) takes place only between two or more computer through a communication medium such as Wires/Cables is known as a Computer Network.
- When data transmission(Audio/Video/Files) takes place only between two or more Mobile devices through a communication medium such as Wires/Cables is known as a Mobile Network.
- When data transmission(Audio/Video/Files) takes place between Computers and Mobile devices through a communication medium such as Wires/Cables is known as a Device Network
- Sender, Receiver, Communication medium/Channel, Protocol and Message are the five components of any computer network. The sender is one who sends the data packets through the communication medium by following protocols and the data packets are received by the receiver.
- Hence, a network can be defined as the set of devices(mobile/computer) connected through a communication link.
