Software

• Software also called programs consists of
  organized sets of instructions for controlling
  the computer.
• Some programs exist for the computer's use, to
  help it manage its own tasks and devices.
• Other programs exist for the user, and enable the
  computer to perform tasks for you, such as
  creating documents.

15
Data

• Data consists of raw facts, which the computer
  can manipulate and process into information that
  is useful to people.
• Computerized data is digital, meaning that it has
  been reduced to digits, or numbers. The computer
  stores and reads all data as numbers.
• Although computers use data in digital form, they
  convert data into forms that people can
  understand, such as text, numerals, sounds, and
  images.

Users

• People are the computer's operators, or users.
• Some types of computers can operate without much
  intervention from people, but personal computers
  are designed specifically for use by people.
