Introduction to Operating System
- An operating system is a low-level software that manages the hardware like the mouse, keyboards, CPU, network interface cards.
- It also manages logical resources such as process, files, memory, I/O, schedulers, etc.
- They acts as an interface between the user’s program and the computer hardware and provides an environment in which users can develop and build their applications.
- It is made up of several components where each component works together for a full -fledged operating system.
- Application programs use the system API (system calls) to get the service of an OS.
- Thus in a nut shell an operating system is the manager which manages all the different resources of a system
