OS: Operating System

09/02/2022
An Operating System (OS) is the primary software that manages a computer’s hardware and software resources. It acts as an intermediary between the user and the computer hardware, ensuring that different programs can run simultaneously without interfering with each other.
Core Functions of an OS
The OS performs several critical tasks behind the scenes to keep a system running smoothly:
- Processor Management: It allocates the CPU’s power to different applications, deciding which process gets the processor’s attention and for how long.
- Memory Management: The OS tracks every byte of memory (RAM). It allocates space for programs to run and “reclaims” that space once the program is closed.
- File Management: It organizes how data is stored on hard drives or SSDs, managing files, folders, and directory structures.
- Device Management: It communicates with hardware like printers, keyboards, and monitors via software called “drivers.”
- User Interface (UI): It provides a way for you to interact with the machine, whether through a Graphical User Interface (GUI) with icons and windows or a Command Line Interface (CLI).
