A client asks or requests information from the server. When it sends a request - it sends it to the server with its own (client) address so that the information will be returned to the correct location.
Client software has to match up to a specific kind of server software and each server requires a specific kind of client software. If you are looking for a web page - you would use a web client to access a web server. If you are want to get your e-mail - you would use a e-mail client. Netscape and Internet Explorer have several different clients built into them. They can actually act as clients for web, gopher, FTP and e-mail to name a few.
Question: Does it matter what kind of computer I have?
