Operating System Definition

windows and linux
We realize it or not, every days we work with this one, Operating System, usually called OS. There are so many variances of OS, e.g. Windows, Linux, Unix, and others. We commonly hear are Windows ( any versions ) and Linux ( any distro ). The main different between this 2 OS is from license. Windows is paid OS and Linux variances is free one. For this posting we aren't talk about different at all, it's just a prologue, but we'll talk about what OS is.

OS has many definitions, but we can't say one is the good definition. We'll list it below :
  • OS is a resource allocator
    Manages all resources
    Decides between conflicting requests for efficient and fair resource use
  • OS is a control program
    Controls execution of programs to prevent errors and improper use of the computer
There is no universally accepted definition for this. “The one program running at all times on the computer” is the kernel. Everything else is either a system program (ships with the operating system) or an application program.
