Define Operating system.
Answers
An operating system (OS), in its most general sense, is software that allows a user to run other applications on a computing device. While it is possible for a software application to interface directly with hardware, the vast majority of applications are written for an OS, which allows them to take advantage of common libraries and not worry about specific hardware details.
The operating system manages a computer's hardware resources, including:
Input devices such as a keyboard and mouse
Output devices such as display monitors, printers and scanners
Network devices such as modems, routers and network connections
Storage devices such as internal and external drives
The OS also provides services to facilitate the efficient execution and management of, and memory allocations for, any additional installed software application programs.
consider the analogy of car:
A driver (user) drives the car (computer).
But actually it’s the engine (OS) which rolls the car
Driver DO NOT interact with the engine directly
Instead he/she interacts with steering, brake, accelerator, clutch, gear etc. (other softwares)
These are then connected with the engine and let’s the driver control the car.
