the Internet each separate computer (to be called) a host: besides it may be your own computer,
your host, even though you may not share resources with the rest of the Internet.
      When you have your own computer, you (to interact) by using the keyboard, screen, and a
mouse. These devices (to be) parts of the computer. With a multiuser computer
(многопользовательский компьютер), each person (to have) his own terminal to use. A ter-
minal has a keyboard, screen, perhaps a mouse, and not much more. All the terminals (to be con-
nected) to the host, which (to provide) the computing power (вычислительная мощность) for
everybody. This arrangement is called a time-sharing system (система разделения времени).
      So, within the Internet each computer is called a host. Within a time – sharing system, the
main computer that (to support) each user on a separate terminal is also called a host.
