What FTP (File Transfer Protocol) is
The standard method for downloading and uploading files over the Internet. With FTP, you can login to a server and transfer files (meaning you can "send" or "receive" files). Some sites have public file archives that you can access by using FTP with the account name "anonymous" and your e-mail address as the password. This type of access is called anonymous FTP. Macintosh owners use a program called Fetch; one of the best FTP programs for Windows is called WS-FTP. Knowing FTP is necessary (and easy) if you want to create your own Web site.
Note: You may also hear this noun used as a verb. For example, "I just finished FTP'ing the last of the files." Or, "I FTP'ed the new images to the site last night."
The meaning of Network
The term actually has many different meanings depending on the person, company, or context in which it is being used. Basically, it is a collection of two or more computers and associated devices that are linked together with communications equipment. Once connected, each part of the network can share the software, hardware, and information contained in the other parts.
The most common types of network are LANs (Local Area Networks, in which the computers share the same office space, room, or building) and WANs (Wide Area Networks, in which LANs are connected at different geographic locations by telephone lines or radio waves, as in wireless communications). Network connections are established by twisted-pair cable, coaxial cable, fiber-optic cable, connectors, or NICs (network interface cards). Network computing depends on protocols that work with a variety of operating systems and network hardware (see: IEEE and ISO). When you hear someone talking about "sharing network resources," they are referring either to client/server networks or peer-to-peer networks.
Also, you may hear Internet companies refer to their "network of Web sites," a group of associated sites that's analogous to a television network or cable TV network. If you have a small business that uses a network for Internet access and file sharing, be sure to have a firewall installed, to protect yourself from unauthorized access.
