ABSTRACT

Although the term “high-speed network” has many definitions, most people would agree that high-speed networks are collections of two or more connected high-speed computers. When these computers are joined in a network, people can share files and peripherals such as modems, printers, tape backup drives, or CD-ROM drives (see Exhibit 1). When networks at multiple locations are connected using services available from phone enterprises, people can send e-mail, share links to the global Internet, or conduct videoconferences in real-time with other remote users. Every high-speed network includes:

At least two computers

A network interface on each computer (a device that lets the computer talk to the network), usually called a network interface card (NIC) or adapter

A connection medium, usually a wire or cable, although wireless communication between networked computers and peripherals is also possible

Network operating system software, such as Microsoft Windows 2000 or Windows NT, Novell NetWare, AppleShare, or Artisoft LANtastic

Most networks (even those with just two computers) also contain a hub or switch to act as a connection point between the computers.
