What is the abstract view of the components of a computer system?
A computer system consists of many resources like hardware and software, which are useful to complete a task. The common required resources are input/output devices, memory, file storage space, CPU etc.
The operating system acts as a manager for all the above resources and allocates them to specific programs and users, whenever necessary to perform a particular task. Therefore, the operating system is the resource manager that means it can manage the resources of a computer system internally. The resources are processor, memory, files, and I/O devices.
An operating system is the interface between the user and the machine. Before there were operating systems, people only used computers using Analog signals and digital signals. Along with the development of knowledge and technology, currently there are various operating systems with their respective advantages.

Hardware − The hardware is the physical part which we can touch and feel, the central processing unit (CPU), the memory, and the input/output (I/O) devices are the basic computing resources of a computer system.
Application programs − Application programs are user or programmer created programs like compilers, database systems, games, and business programs that define the ways in which these resources can be used to solve the computing problems of the users.
Users − There are different types of users like people, machines, and even other computers which are trying to solve different problems.
Operating system − An operating system is the interface between the user and the machine which controls and coordinates the use of the hardware among the various application programs for the various users.
