💻 Computer Basics

Explanation: 1 terabyte = 1024 gigabytes (binary). In decimal (SI units), 1 TB = 1000 GB. Hard drive manufacturers often use decimal, while OS typically uses binary.

Explanation: GPU stands for Graphics Processing Unit. It handles rendering graphics and images. Modern GPUs are also used for AI, machine learning and scientific computing.

Explanation: A keyboard is an input device — it sends data to the computer. Output devices display results (e.g., monitor, printer). The CPU is the processing unit.

Explanation: RAM (Random Access Memory) is volatile temporary memory used by the computer to store data for currently running programs. It is much faster than a hard drive but loses data when power is off.

Explanation: An operating system (OS) is system software that manages computer hardware, software resources and provides services for programs. Examples: Windows, macOS, Linux.
