What are the classification of computer software and definition?

Answer 1

Software is a set of programs used to operate computers and related devices.

The two main classifications of software:

• System software
• Application software

1) System software - software designed to operate the computer hardware and to provide a platform for running application software.

Operating Systems are a collection of programs that make the computer hardware conveniently available to the user and also hide the complexities of the computer's operation.

Utility programs are small, powerful programs with a limited capability, they are usually operated by the user to maintain a smooth running of the computer system.

Library programs are a compiled collection of subroutines

Translator software (Assembler, Compiler, Interpreter)

1. Assembler translates assembly language programs into machine code (A binary code that a machine can understand).
2. Compiler translates high level language code into object code (which is the machine language of the target machine).
3. Interpreter analyses and executes a high-level language program a line at a time. Execution will be slower than for the equivalent compiled code as the source code is analyzed line by line

2) Application software - software designed to help the user to perform specific tasks.

• General purpose application software.
• Special purpose application software.
• Bespoke application software
