Basic Operational Concepts

Instructions take a vital role for the proper working of the computer.

An appropriate program consisting of a list of instructions is stored in the memory so that the tasks can be started.

The memory brings the Individual instructions into the processor, which executes the specified operations.

Data which is to be used as operands are moreover also stored in the memory.

operating system has three main functions: (1) manage the computer's resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software. Keep in mind, however, that much of the work of an operating system is hidden from the user; many necessary tasks are performed behind the scenes. In particular, the first listed function, managing the computer's resources, is taken care of without the user being aware of the details. Furthermore, all input and output operations, although invoked by an applications program, are actually carried out by the operating system. Although much of the operating system functions are hidden from view, you will know when you are using an applications software package, and this requires that you invoke-call into action-the operating system. Thus you both establish a user interface and execute software.
