An operating system acts as an intermediary between the user of a computer and computer hardware. In short its an interface between computer hardware and user.
- The purpose of an operating system is to provide an environment in which a user can execute programs conveniently and efficiently.
- An operating system is software that manages computer hardware and softwares. The hardware must provide appropriate mechanisms to ensure the correct operation of the computer system and to prevent user programs from interfering with the proper operation of the system.
- Operating system is a program running at all times on the computer (usually called the kernel), with all else being application programs.
- Study of operating system is an essential to understand the overall working of
computer system, tradeoffs between performance and functionality and the division of jobs
between hardware and software. This course introduces the concepts of memory management,
device management, process management, file management and security & protection
mechanisms available in an operating system. The course helps the learner to understand the
fundamentals about any operating system design so that they can extend the features of operating
system to detect and solve many problems occurring in operating system and to manage the
computer resources appropriately.
