Operating System
An operating system (OS) is system software that manages a computer's hardware and software resources, acting as an intermediary between the user and the computer's hardware. It handles fundamental tasks such as memory and process management, file management, and controlling input/output devices, allowing other programs to run and users to interact with the computer in an intuitive way.
Key functions of an operating system
Resource management: Manages and allocates computer resources like the CPU, memory, and storage space among various programs and users.
Process management: Controls the execution of applications, schedules tasks, and manages interruptions to ensure smooth operation.
File management: Organizes and keeps track of files and directories on the disk.
Hardware abstraction: Provides a consistent and user-friendly interface for applications to interact with the hardware, eliminating the need for users to understand complex machine code.
User interface: Provides a means for users to communicate with the computer, such as a graphical user interface (GUI) or a command-line shell.
Common services: Offers common services to other software, such as networking and security features.
