The major function of an operating system is to manage all resources of a system.
The special purpose of the operating system is to manage the computer hardware resources. The operating system also provides common services for the computer programs.
The operating system provides a way for the user to manage system hardware and resources while providing a reasonably usable interface for the user to be able to use it.
Unix internals refer to the algorithms and techniques used by the resident operating system to manage resources.
The primary function of Unix is the same as it would be for an Operating System - to manage resources and provide security.
Resources are the responsibility of the operating system (OS). The programmer can request resources from the OS, but must release them to the system as soon as they are no longer required. As such, the programmer must manage the resources required by the program.
If there is no OS, you can't boot your PC, and therefore, can't do anything but access BIOS until you install an OS. You can do nothing without an OS. problems if no operating system to manage computer system
The two primary objectives of an operating system are:1. to enable running of application programs.2. to manage the different computer resources.
The UNIX OS is an operating system, which has the primary responsibility of managing security and resources for users. It has the same "purpose" as any other operating system, such as Windows, z/os, VMS, etc.
so as to infom the processor of what it ought to do
One of the main things the operating system manages is the memory. The operating system contains a memory manager, dispenses memory to applications, and keeps track of what is used. It also consolidates and defragments the memory and returns relinquished memory back to the pool of available memory.The operating system uses drivers to match itself to the exact hardware that is in the system and to provide ways to use and manage the hardware.The operating system uses the storage drivers to provide APIs to manage disk I/O, and it uses file system drivers to manage the file systems needed to store files.
Operating systems are software written to provide a way to manage system resources and to provide a interface for the user to interact with and operate the computer.
