How computer communicate?
i m going to discuss here that how computers communicate large amounts of information over a single wire or communication channel:-
Protocol: A set of rules that are used to accomplish a task more quickly, more efficiently and more reliably.
Handshaking: An indication that the current task has been completed.
Encoding: Putting the information in a format that can be easily understood by the program or person receiving it.
Half Duplex: This is when you can only send or receive information at one time using communication medium.
Full Duplex: Being able to send and receive information simultaneously.
Packet: A group of information to be sent or received.
Address: A way of identifying each user. In the Internet this is the same as a web site url.
Arbiter: This is usually a software program that decides who gets to go first when multiple requests come for accessing the same information. On the Internet, this is what tells you that it failed to connect, try again later when many people are visiting the same site.
Node: This is a connection on the network. When you connect to the Internet, your computer becomes a node or connection on the World Wide Web.
Error detection/correction - these is what happens when you make a request for information or send an e-mail and it does not work.
Broadcast message: This is when one person talks and all others on the network are supposed to listen.
One to One message : This is where you establish a conversation with another person or computer much like a telephone conversation
