An Operating System (OS) acts as an interface connecting a computer user with the hardware of the computer. An operating system falls under the category of system software that performs all the fundamental tasks like file management, memory handling, process management, handling the input/output, and governing and managing the peripheral devices like disk drives, networking hardware, printers, etc.
Some well-liked Operating Systems are Linux, Windows, OS X, Solaris, OS/400, Chrome OS, etc. Archiver 3 0 0 download free. https://pcngl.over-blog.com/2021/01/arcsoft-camera.html.
Features of Operating System
Here is a list of some significant functions of an Operating System, which is found common, is almost all operating system:
- Memory Management
- Processor Managing
- Device Managing
- File handling
- Security Handling
- System performance controlling
- Job accounting and handling
- Error detecting and handling
- Synchronization with other software and users
Objectives of Operating System
An operating system consists of a special program that controls the execution of the application program. The OS acts as an intermediary between applications and hardware components. Marvell 91xx config ata device driver for mac. OS can be thought of as having three objectives. These are:

IBM was slow to introduce operating systems: General Motors produced General Motors OS in 1955 and GM-NAA I/O in 1956 for use on its own IBM computers; and in 1962 Burroughs Corporation released MCP and General Electric introduced GECOS, in both cases for use by their customers. The first operating system to introduce system calls was University of Machester's Atlas I Supervisor. The operating system could have additional reasons to rotate through jobs, including giving higher or lower priority to various jobs (and therefore a larger or smaller share of time and other resources).

Many of the ideas in MULTICS were subsequently used at Bell Laboratories in the design of UNIX OS.
- Convenience: It makes a computer more suitable to use.
- Efficiency: It provides the computer system resources with efficiency and in easy to use format.
- Ability to develop: It should be built in such a way that it permits the efficient development, testing, and installation of new system functions without interfering with service.
