039. protocols: the language of machines (ks5)
Analyse network protocols to understand the strict rules and standards that govern how different computer systems communicate and share data globally.
For a smartphone in Tokyo to load a webpage hosted on a server in London, both devices must speak the exact same language. This is achieved through network protocols - a strict set of rules governing digital communication. In this advanced module, we will dissect these protocols, exploring how the layered TCP/IP stack ensures reliable, standardised data transmission across heterogeneous networks.
