Hardware refers to various computer components such as monitors, motherboards, CPUs, RAM, expansion cards, power supplies, optical disk drives, hard disks, keyboards, and mice. It provides essential functions like displaying visual information, serving as the main circuit board that holds other components, processing instructions, providing data storage, adding new capabilities, supplying power, reading optical discs, long-term storage, text input, and pointing/selecting onscreen. Hardware is critical infrastructure that allows computers to function.

1. Hardware is a general term for equipment such as keys , locks , hinges , latches , handles , wire , chains, plumbing supplies, tools , utensils , cutlery and machine parts. Household hardware is typically sold in hardware stores . Made by: Sergio López Domínguez Juan Antonio Del Pino García Hardware

2. Monitor A monitor or display (sometimes called a visual display unit ) is an electronic visual display for computers . The monitor comprises the display device, circuitry , and an enclosure. The first computer monitors used Cathode ray tubes (CRTs), which was the dominant technology until they were replaced by LCD monitors in the 21st Cent

3. Motherboard In personal computers , a motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, providing connectors for other peripherals.

4. CPU An Intel 80486DX2 from below The central processing unit ( CPU ) is the portion of a computer system that carries out the instructions of a computer program , to perform the basic arithmetical, logical, and input/output operations of the system.

5. RAM Random-access memory (RAM) is a form ofcomputer data storage. Today, it takes the form of integrated circuit that allow stored data to be accessed in any order with a worst case performance of constand time.

6. Expansion card The expansion card in computing is a printer circuit board that can be inserted into an expansion slot of a computer motherboard or back planeto add functionality to a computer system via the expansion bus.

7. Power supply A power supply unit ( PSU ) supplies direct current (DC) power to the other components in a computer. It converts general-purpose alternating current (AC) electric power from the mains (110 V to 120 V at 60 Hz [115 V nominal] in North America, parts of South America, Japan, and Taiwan

8. Optical disk drive In computing , an optical disc drive ( ODD ) is a disk drive that uses laser light or electromagnetic waves near the light spectrum as part of the process of reading or writing data to or from optical discs .

9. Hard disk A hard disk drive ( HDD ; also hard drive or hard disk is a non-volatile, random access digital magneticdata storage device. It features rotating rigid platters on a motor-driven spindle within a protective enclosure.

10. keyboard A key being pressed on a computer keyboard. Incomputing, a keyboard is a typerwrite style keyboard, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches.

11. Mouse A computer mouse with the most common standard features: two buttons and a scroll wheel, which can also act as a third button Incomputing, a mouse is a pointing divice that functions by detecting two dimensional motion relative to its supporting surface.
