Computer hardware can be defined as the physical components that a computer system needs to function.
This distinguishes it from software, which consists of written instructions telling physical components what to do. Laptop Laptop computer Touchscreen Core Inch Laptops Ghz Pci Case Adapter Full-hd Burner Ports Macbook Gtx Intel Core Geforce Pc gamer Bluetooth
Internal and external hardware components
The components that make up the hardware can be classified as internal or external. Internal components are those installed inside the computer, typical examples being the motherboard, power supply and central processing unit (CPU). External components are those connected to the outside of the computer, they can also be called peripherals or peripherals, common examples being the monitor, keyboard and mouse.

I will explain each of the components listed in more detail below.
The motherboard (known colloquially as the mobo) is the main circuit board of a computer. It houses the processor and functions as a hub through which all other hardware passes. It allocates power to the other components, coordinates them and allows communication between them.

2. Central Processing Unit (CPU)
The central processing unit, or CPU for short, is responsible for processing all the information from the programs run by your computer. Each CPU has a clock speed, which is the number of instructions it can process in a given second, measured in gigahertz. The quality of a computer's processor has a major effect on the overall performance of the system.
3. Power supply
The main role of the power supply is to convert alternating current (AC) from an outlet into direct current (DC). The computer's components need DC to function normally. The power supply also controls the voltage to avoid overheating problems.

4. Random Access Memory (RAM)
Random access memory (RAM) is the physical hardware inside a computer that temporarily stores data. It is normally located in the memory slots on the motherboard. Its role is to serve as the computer's "working memory" for information created by programs. Generally speaking, the faster the RAM, the faster the processing speed at which the memory moves data to other components.
5. Hard disk drive (HDD)
The hard disk is the primary data storage device in a computer. It is where the operating system, software titles, and most files are stored. Unlike RAM, hard drives are non-volatile, which means that they retain their stored data even when they are turned off.

6. Video Card
The video card (also known as the graphics card) is an expansion card that allows the computer to send output images to a video display device such as a monitor. The video card is usually installed via a slot on the motherboard.
7. Solid-State Drive (SSD)
SSDs are designed to be housed inside the computer as an alternative to traditional hard drives. Although they look almost identical to traditional hard drives from the outside, they have no moving parts. This means they use less power, access data faster and are generally more reliable.

8. Optical disc drive (e.g. BD drive, DVD drive, CD drive)
An optical disc drive (ODD) uses laser light or electromagnetic waves to read or write data to optical discs. Common optical media designed for use with these types of drives are compact discs, DVDs and Blu-ray discs. Optical disc drives may also be referred to as disk drives, CD drives, DVD drives and BD drives.
9. Card reader (e.g. SD, SDHC)
Most personal computers and tablets have built-in memory card readers. This allows them to read data from memory cards, which are portable electronic storage devices used to store digital information. Most contemporary memory cards use flash memory, although other memory technologies are currently being developed.

10. The screen or monitor
The monitor is a hardware device that displays video and graphics information generated by the computer via the video card. Monitors can also be called video display units, video display terminals or simply screens. Older monitors were bulky and built using cathode ray tubes, but nowadays they normally use LCD technology and are lighter and thinner.

The keyboard is a typewriter-like device that allows users to interact with their computer. Users enter text, characters and other commands by pressing special buttons called keys. Although the keyboard is normally considered an external hardware component, it is an essential part of most computer systems.
The computer mouse is a handheld pointing device used to manipulate objects on a computer screen. The standard modern mouse is capable of directing a cursor using optical sensors. Most mice also have two buttons (left click and right click), used for selection and access to menus, and a scroll wheel.
Printers are output devices that generate hard copies of electronic data stored on the computer, usually in the form of text or images on paper. The most common types of modern printers use inkjet or laser technology and connect to the computer via the computer's USB port or via WI-FI.
Computer speakers are a common output device and are used to listen to music, movies and other audio. They are available in a range of qualities and prices, with the more sophisticated versions having an additional subwoofer to provide enhanced bass output.
15. External hard drive
An external hard drive is a drive that usually connects to the computer's USB port. Some are powered by the computer via the data cable, others need an AC wall connection. The main advantage of an external drive is its portability, you can carry relatively large amounts of data with you or transfer data between different computers.

16. Desktop Image Scanner
A desktop image scanner is an input device that transfers images or text to a computer using optical technology. The computer converts the signal into a digital image, allowing it to be edited, emailed or printed.
Projectors are external hardware devices that allow a room full of people to experience images generated by a single computer. They can "project" still or moving images onto a blank wall, screen or other surface. Modern digital projectors are often used to watch movies, enhance presentations or as an educational aid. They connect to a computer via the HDMI port.
A joystick (also known as a control column) is an input device used by a gamer to interact with a computer game. Joysticks are also used to control a variety of real-world vehicles, such as airplanes, trucks, wheelchairs, surveillance cameras, and unmanned underwater vehicles, which are becoming increasingly computerized.
Headphones are a hardware output device used to listen to audio. Typically, they plug into a computer line out or into speakers. They allow the listener to enjoy music, movies, or other audio privately and without disturbing others nearby.
20. USB flash drive
A USB flash drive is a portable data storage device. Unlike optical drives, flash drives have no moving parts, making them more durable. A flash drive has a built-in USB interface and connects to the computer via a USB port.
