FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Operating systems define how a computer stores files, switches between different applications, manages memory, keeps itself secure, and interacts with peripherals like printers and cameras.

Detailed explanation-2: -All data is stored in files, within folders, within drives. The file management system does this by creating a virtual file structure of the physical components. It is a hierarchical structure starting with the root directory, a bit like an upside-down tree.

Detailed explanation-3: -The operating system constantly swaps out the unused parts for the parts being used. This gives each process its own space and keeps them from corrupting one another. This technique is called virtual memory management.

Detailed explanation-4: -Operating systems use two components to manage computer programs and applications: The kernel is the core inner component that processes data at the hardware level. It handles input-output management, memory and process management. The shell is the outer layer that manages the interaction between the user and the OS.

Detailed explanation-5: -An operating system is the most important software that runs on a computer. It manages the computer’s memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer’s language.
