What is System Software and what are its types

System software is one of the category of software. The system software controls the computer. It communicates with computer's hardware ( key board, mouse, modem, sound card etc) and controls different aspects of operation. Sub categories of system software are :

1.   Operating system
2.   Device drivers
3.   Utilities software

Operating System

 An operating system ( sometimes abbreviated as "OS") is the program that manages all the other programs in a computer. It is a integrated collection of routines that service the sequencing and processing of programs by a computer. Note: An operating system may provide many services, such as resource allocation, scheduling, input/output control and data management.

Device Drivers 

 The device driver software is used to communicate between the devices and the computer. We have monitor, keyboard and mouse ( basic input/output), if we look at the properties of these devices we will see that the operating system has installed special software to control these devices. This piece of software is called device driver software. Whenever we attach a new device with the computer, we need software to communicate with this device. These kind of software are known as device drivers e.g Sound Card driver and Modem driver.

Utility Software 

 Utility software is a program that performs a very specific task, usually related to managing system resources. To understanding the use of utility software, depth knowledge of utility programs are required. For this there will publish another post for utility software.
