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

  1. Application – Deals with the production and packaging of data.
  2. Transport – Deals with making and breaking connections via routers
  3. Internet – Deals with providing links across different network types
  4. Link – Deals with passing data to the physical network
