Help me please.... I have a test.. "Computers Communications."?

Question

Help me please I am very confused about computers Comunicatios

1) I konw many companies in order to be more productive use a process Known as electronic data interchange (EDI). Since I am interested in opening my own business could you explain what this process is and how it could maybe make my business more productive.

2)I heard the term handshaking used when the network people were talking about computers communicating with one another. I know what a handshake is when talking about people. However, I never heard the term used when talking about computers. What does this term mean.

3)The small company I work for is expanding its network. I heard the networks engineers talk about a T1 and a T3 line.

What do they mean ty these lines. Does this mean the company has to lay new wire and dig up the grounds around the building?

4)Are instant messaging and e-mail the same thing. I think they are but friend says no way. who's right? If there is a difference, what is it?
