An operating system is a software that manages the computer hardware. 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.

Is a core set of programs that control and supervise the hardware of a computer and provide services to other system software, application software, programmers and users of a computer. It acts as an intermediary between users of computer hardware.

A computer system has many resources (hardware and software), which may be require to complete a task. The commonly required resources are input/output devices, memory, file storage space, CPU etc. The operating system acts as a manager of the above resources and allocates them to specific programs and users as necessary for their task.

An Operating System (OS) is a crucial software layer that serves as the interface between computer hardware and users or application programs. It manages and coordinates hardware resources such as the CPU, memory, storage, and input/output devices, ensuring efficient and effective utilization.

Systems Design refers to the process of defining the architecture, components, modules, interfaces, and data for a system to meet specified requirements. It is the blueprint for how the system will operate and interact with other systems or users. This phase follows the analysis phase in the systems development life cycle (SDLC). Systems Implementation is the phase where the designed system is developed, tested, and deployed. It involves translating the plans into an operational system that meets user needs. Implementation often includes installation, configuration, training, and ongoing support.
