What Are Communication Protocols?

We have learned that a communication protocolRules, such as the format of information, for communication. is a set of rules for communication. In this exercise, we have encountered several actual rules in use.

• For HTTPA communication protocol that provides the mechanism for viewing web pages., it is necessary to organize the location of web page files in a format like Item: /joho1/internet.html, such as Item: Content.
• For TCPA communication protocol that divides data into packets and performs various controls to ensure reliable delivery of information. If data is lost during transmission, it is retransmitted., information is divided into packetsIndividual pieces of information divided to facilitate communication. of every 100 characters.
• For IPA communication protocol for managing the destination of information., the destination is managed using IP addressesA network address used by IP to manage destinations and communication routes..
• For EthernetA communication protocol that performs controls such as matching the high and low voltage of cables to the binary 1 and 0 when using LAN cables., the high and low voltage of the cable corresponds to the binary 1 and 0.

By learning these specific examples of rules, have you gained a more concrete image of communication protocolsRules, such as the format of information, for communication.?
