Hardware

Hardware refers to all the physical parts of a computer or digital device that can be touched and observed. It includes components such as the processor, memory, storage drives, screen, keyboard, battery, and many other electronic elements.

Unlike software, which consists of programs and instructions, hardware forms the material structure that allows a device to operate. Each component has a specific role, and they work together to process information, store data, and perform tasks requested by users.

Computer hardware has changed greatly over time, becoming smaller, faster, and more efficient. Modern devices contain tiny electronic circuits capable of carrying out billions of operations per second.

Some hardware components are found inside the device, such as the processor and memory, while others are external accessories, such as printers, headphones, or external drives. Understanding hardware helps explain how digital technologies function and how engineers design, improve, and repair electronic systems.
