Network Protocols and Layers
Networking protocols define rules and conventions for communication. Protocols determine the speed of transmission, size of the message, error checking methods and type of transmission (synchronous or asynchronous). The protocols are established between sender and receiver before starting communication. This is done by handshaking, which is the process of negotiation between the sender and receiver by an exchange of messages. Once handshaking is complete, data packets travel from sender to receiver through various routers. Data packets are exchanged between various routers; this is called packet switching.
This GCSE Computer Science module introduces network protocols and layers to your students, explaining:
- Network Addressing
- Protocols
- Network layers
- What is encapsulation of data
- Transfer of data
