C
An 80×80×25 mm computer fan
- Card reader [2][3][4] – a data input device that reads data from a card-shaped storage medium.
- CD/DVD reader/writer
- Combo drive
- DVD Multi
- SuperDrive
- Super Multi – a type of DVD drive that can read and write all DVD formats.
- Central processing unit (CPU) [2] – the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.
- Computer case – the enclosure that contains most of the components of a computer (usually excluding the display, keyboard and mouse).
- Computer data storage [2] – a technology consisting of computer components and recording media used to retain digital data. It is a core function and fundamental component of computers.
- Computer keyboard [5]
- Computer fan
- Computer monitor [2] – an electronic visual display for computers. A monitor usually comprises the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) or a flat panel LED display, while older monitors used a cathode ray tubes (CRT).
D
E
A PCI digital I/O expansion card
- Expansion card – a printed circuit board that can be inserted into an electrical connector, or expansion slot on a computer motherboard, backplane or riser card to add functionality to a computer system via the expansion bus. An expansion bus is a computer bus which moves information between the internal hardware of a computer system (including the CPU and RAM) and peripheral devices. It is a collection of wires and protocols that allows for the expansion of a computer.

- Hard disk drive [2][6] – a data storage device used for storing and retrieving digital data using one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. The platters are paired with magnetic heads arranged on a moving actuator arm, which read and write data to the platter surfaces.[7]
- Apple ProFile – the first hard drive produced by Apple Computer, initially for use with the Apple III personal computer
- Jaz drive
M
- Memory card
- Microphone
- Modem [2][8]
- Motherboard [2] – the main printed circuit board (PCB) found in general purpose microcomputers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals.
N
- Network interface controller [9] – also referred to as LAN card and network card
O
P
- Power supply unit (PSU) – converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.

- Random access memory (RAM) – a form of computer data storage that allows data items to be accessed (read or written) in almost the same amount of time irrespective of the physical location of data inside the memory. RAM contains multiplexing and demultiplexing circuitry to connect the data lines to the addressed storage for reading or writing the entry. Usually more than one bit of storage is accessed by the same address, and RAM devices often have multiple data lines and are said to be '8-bit' or '16-bit' etc. devices. In today's technology, random-access memory takes the form of integrated circuits.

- Solid state drive [6] – a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently. It is also referred to as a solid-state disk, but it contains neither an actual disk nor a drive motor to spin a disk.
- Sound card – an internal expansion card that facilitates economical input and output of audio signals to and from a computer under control of computer programs. It is also referred to as an audio card.
- SuperDisk – a high-speed, high-capacity alternative to the 90 mm (3.5 in), 1.44 MB floppy disk. The SuperDisk hardware was created by 3M's storage products group Imation in 1997,
T
V
- Video card – also referred to as a graphics card and several other names, a video card is an expansion card which generates a feed of output images to a display (such as a computer monitor).
W
Webcams typically include a lens (shown at top), an image sensor (shown at bottom), and supporting circuitry.
- Webcam [2][11] – a video camera that feeds or streams its image in real time to or through a computer to computer network. When "captured" by the computer, the video stream may be saved, viewed or sent on to other networks via systems such as the internet, and email as an attachment.
