Protocols are important on a network because without protocols computers would not be able to talk to each other and so the internet would be useless. For example if you are in France, and did not speak French you would not be able to talk to anyone because you wouldn’t be able to understand them, and they could not understand you if they did not speak your language. This is the same for Internet protocols. If one computer wants to talk to another then they would need to understand the same protocol. So basically Protocols are the rules that allow communication between two or more computers.
The main internet protocols are;
HTTP (Hyper Text Transfer Protocols)
HTTP helps us display webpages. If the computer did not know this protocol, then you would not be able to view the webpage because the computer would not understand the code used and so it would be unable to display the webpage.
FTP (File Transfer Protocol)
FTP helps us send and receive files sent from other computers. If either of the two computers did not understand this protocol then you would not be able to send and receive files because the computer would not know the “language” and so sending a file would be impossible.
SMTP/POP3 (Simple Mail Transfer Protocol & Post Office Protocol)
SMTP and POP3 is the protocol for sending E-mails SMTP allows you to send emails, and its usually POP3 that allows you to receive them.
There are lots of different network standards that computers use. There are standards for hardware, for Ethernet and for signaling, wireless. IEEE 802.11g is a wireless network standard that is used to say how strong the signal is, and the specifications for the type of radio used. A standard for Ethernet which is known as IEEE 802.3 is the standard for hardwired networks. It defines what type of wiring can be used, the connector styles and the power requirements.
So in conclusion Protocols are needed so your computer can interact with other computers for things such as using the internet and sending and receiving files and emails. Protocols are the “language” computers use to talk to each other. Standards are important so all networks have to follow the same rules. Standards are a set of guidelines on how different companies need to make their equipment.
