This document discusses three types of system software: system control programs like operating systems and device drivers that control program execution and device functioning; system support programs such as utility programs that provide routine services to users and other programs including backup, data recovery, compression, and anti-virus utilities; and system development programs that assist in creating other computer programs, including programming languages and language translators.

1. Types of system
software

2. Overview:
 Types of system software.
 System control software.
 System support software.
 System development software.

3. Types of system software:
 Three types of system software
