To make a network work effectively protocols need to be put in place
What are protocols?
A protocol is a set of rules
The rules that govern data transmission can be simplified to the TCP/IP stack
What is the TCP/IP stack?
TCP/IP divides how a network should pass data into layers so that each layer can be individually dealt with
There are 4 layers that need to be considered
- Application – Deals with the production and packaging of data.
- Transport – Deals with making and breaking connections via routers
- Internet – Deals with providing links across different network types
- Link – Deals with passing data to the physical network
