Learn Operating System describes as an interface between user and machine. It gives an environment to the user. The user can perform different tasks in a suitable and efficient way.
Learn Operating system behaves like a manager of the resources such as software and hardware which need to perform different tasks. Therefore, the Operating system is the resource manager. It can manage the resources of a computer fundamental system Internally. The resources are memory, processor, files, and input and output devices. However, In a simple way, the Operating system is the interface between the user and the hardware.
Operating System Management Tasks:
- Processor Management requires adding the task into order and pairing them into manageable sizes before they to the Central Processing Unit (CPU).
- Storage management Directs stable data storage.
- The application allows standard communication between software and Machine.
- Memory Management synchronizes the data from Random Access Memory (RAM) and modifies the need for virtual memory.
- Device Management Gives an interface between attached devices.
- The user interface allows you to communicate with your Machine.
Functions of Operating System
- It implements basic computer tasks. Such as, managing the many peripheral devices like mouse and keyboards.
- It boots the computer
- It gives a user interface, such as a graphical user interface (GUI), Command line.
- OS holds Operating system resources like computer memory and sharing of the CPU time by many peripheral devices or applications.
- It gives file management which refers to the way that the operating system operates, stores retrieve, and save data.
- Error Handling is completed by the operating system. It takes preventative measures whenever needed to avoid errors.
