System software is a type of computer program designed to run a computer’s hardware and application programs. In simple terms, it manages and controls computer hardware so application software can function.
It acts like the foundation of a house — you don’t always see it, but without it, nothing else can stand or work properly.
Key Features of System Software
- Interface between user and hardware
- Controls and coordinates hardware components
- Boosts system performance
- Handles system-level security and permissions
- Runs continuously in the background
Types of System Software
Here are the main types of system software with simple explanations:
1. Operating System (OS)
The core of system software. It manages hardware, software resources, and provides a user interface.
Examples:

2. Device Drivers
These are special programs that let your OS communicate with hardware devices like printers, keyboards, or graphics cards.
Examples:
- Printer driver
- Audio driver
- Display driver
3. Utility Software
Helps maintain, analyze, and optimize a computer system.
