What is an Operating System?

An Operating system is a program that acts as an intermediate between a user of a computer and the computer hardware.

An Operating System performs all the basic tasks like managing file, process, and memory.

Operating System is a collection of system programs that together control the operations of a computer system.

Some examples of operating systems are UNIX, MS-DOS, MS-Windows, Linux, Mac-OS etc.

It also has some basic function.

In large systems, it has even greater responsibilities and powers.

Nowadays there are three types of Operating Systems commonly used. The first is Monolithic OS, where the entire OS is working in kernel space. The second is Modular OS, in which some part of the system core will be located in independent files and the third is Micro OS in where the kernel is broke down into a separate process.

 

Examples of OS:-

Microsoft Windows (like Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP), Apple’s Mac OS (formerly OS X), iOS, Chrome OS, BlackBerry Tablet OS.

 

  Operating System Goals:-

  • Execute user programs and make solving user problems easier.
  • Make the computer system convenient to use.
  • Use the computer hardware in an efficient manner.
