How Does a Computer Actually Work?

07.05.2025

A computer is an electronic machine designed to process information according to specific instructions. At its core are components like the CPU (central processing unit), which acts as the brain, and RAM (random access memory), which temporarily stores data for quick access. The hard drive or SSD keeps your files and programs even when the device is turned off, while the mainboard connects all parts and enables communication between them. The graphics card handles the rendering of images and videos, especially important for gaming or design. When you press the power button, a small program called the BIOS starts the system and loads the operating system. This process enables the computer to interpret your actions, whether you're typing, watching videos, or coding. Understanding how a computer functions is essential for anyone interested in technology or programming.
