Many computers are general purpose and support a wide variety of tasks. Six basic types of computers are designed Second, software Programs, a series of related instructions, organized to achieve a common goal, tell the computer what tasks to perform and how to do them. Without software, a computer can't do anything at all. When a computer uses a particular program, it is said to be running or executing that program.
