What is the Operating System?
The operating system is an interface between the user and computer hardware. The hardware of the computer cannot understand the human-readable language as it works on binaries i.e. 0’s and 1’s. Also, it is very tough for humans to understand the binary language, in such case we need an interface which can translate the human language to hardware and vice−versa for effective communication.
Types of Operating System:
There are Three Types of Operating Systems. They are:
- Single User − Single Tasking Operating System
- Single User − Multitasking Operating System
- Multi-User − Multitasking Operating System
Single User – Single Tasking Operating System
In this type of operating system, only one user can log in to the system and can perform only one task at a time.
Single User − Multitasking Operating System
This type of Operating System supports only one user to log into the system but a user can perform multiple tasks at a time, browsing the internet while playing songs, etc.
E.g: Windows 98, ME.
Multi-User − Multitasking Operating System
This type of Operating System provides multiple users to log into the system and also each user can perform various tasks at a time. In a broader term, multiple users can logged into the system and share the resources of the system at the same time.
E.g: UNIX, LINUX etc.
