Section 1: P2 – Add separate information sheets/leaflets/web page that describes why different network standards and protocols are necessary. Your examples should be realistic.

Different protocols and network standards are necessary for different systems to interact with each other. Protocols are used to communicate, authenticate and used for error detection and recovery.

The protocol allows computers to communicate with each other by setting the "ground rules". It allows for data to be retrieved back and fourth from computers.

TCP/IP (Transmission control protocol/internet protocol) is the most common protocol, and is actually two distinguished protocols, joined together (TCP (Transmission Control Protocol) and IP (Internet Protocol). Every protocol does a various "job". Others, such as FTP (File transfer protocol) are used for particular duties to be performed.

Network Standards are entirely separate, although related to each other. The network standard is the fundamental rules and regulation networks need to be abide by in order to run such as the types of certain cables, the amount of data they can transfer in order for the network to run efficiently.

This is usually done to ensure backwards compatibility and compatibility from vendor to vendor. If each company made its own "protocol standard" and didn’t allow it to talk with another’s "protocol standard". That company would become very rich by being the sole provider, or out of business because nobody would buy it because of its uniqueness.

To conclude standards and protocols are what allow different computers, from different companies, running different software to communicate with each other.
