| Protocol | Purpose |
|---|---|
| TCP/IP | |
| HTTP |
Complete the table. [4]
(c) Explain why protocols are necessary for devices to communicate on a network. [1]
Answer Details
(a) A network protocol is a set of rules that governs how data is transmitted and received across a network, ensuring devices can communicate with each other. [1]
(b) The completed table:
| Protocol | Purpose |
|---|---|
| TCP/IP | Manages the routing of data by breaking it into packets, sending them across the network via the most efficient route, and reassembling them at the destination in the correct order. It is the fundamental protocol suite of the internet. [2] |
| HTTP | Defines how web browsers request web pages from web servers and how the server responds by sending the requested page content back to the browser. It governs all standard web browsing communication. [2] |
(c) Why protocols are necessary:
Without a common set of rules, devices from different manufacturers using different operating systems would not be able to understand each other's data formats and communication methods, making network communication impossible. [1]
