Computer System
Two major components of a computer system
1. Hardware
The components of a computer system that are tangible are called hardware.
2. Software
The intangible components of the computer system are called software. These intangible components are programmed or coded to execute with the help of synced hardware. The software is used to obtain the Desire useful output after its execution.
Two Types Of Software
1. System Software
The type of software that acts as an interface between the application Software and the Hardware.
Example-
- Operating System
- Windows 7
- Windows 10
- Linux
- Unix
- DOS (Disk Operating System)
- Device Driver
- Printer Driver
- Sound Driver
2. Application Software
Application Software is a type of software that acts as an interface between the user and system software.
Example-
