What is an operating system software or hardware?
An operating system is a generic term for software that interfaces and buffers between the users and user application programs and the computer hardware which includes memory, disk drives, etc.It can be as simple as the old(er) named Disk Operating System (MSDOS, PCDOS, DRDOS, DOS-11, DOS/360, etc) and Tape operating system (TOS) which had no restrictions on what a running program could do but loaded programs into memory, start them, and did respond to requests by programs for system functions such as finding, reading and writing files.It can be as complex as a multiuser, multiprogramming, multiprocessing system where it manages memory, CPU(s), device assignment, security, communications and other functions as in Z/OS. IBM I, OpenVMS, Unix implementations, Linux, or Windows.It is software. You can install and uninstall operating systems as you like, without changing any hardware inside your computer.The operating system is the system your using such as Microsoft's Windows versions (Windows XP, Windows vista, Windows 7, etc.), Apples Mac OS X snow leopard, Linux distributions.The OS is a system software which provides services for application software. The OS controls Hardware and software like MS word, Photoshop and wordpad.It is the software of your system that allows you to do pretty much everything. Run programs, go onto the Internet or even look at pictures.The Operating system is a software consisting of programs and data that runs on computers and manages the hardware resources and also provides a platform for various application software.An operative system is software serving as a foundation for processes on your computer. The operating system undertakes memory management and important security and stability enhancing tasks that is required for other software to run correctly. Computer hardware often differ in design and function and part of the operative systems's job is to minimize the design work needed by the other layers software to support each type of hardware.
