Parts of Computer Names and Their Functions

Central Processing Unit (CPU)

Often referred to as the “brain” of the computer, the CPU processes instructions and carries out tasks. It’s responsible for executing programs and ensuring your computer runs efficiently.


The motherboard is like the backbone of a computer. It houses the CPU, RAM, and other essential components, providing connections so they can communicate with each other.

Random Access Memory (RAM)

RAM is the computer’s short-term memory. It temporarily stores data that the CPU might need quickly. The more RAM a computer has, the faster and more efficiently it can perform tasks.

Hard Drive

The hard drive is the computer’s long-term storage. It retains all your files, documents, and software, even when the computer is turned off.

Graphics Processing Unit (GPU)

Also known as a video card, the GPU renders images and videos. It’s essential for tasks that require high-resolution visuals, like gaming or video editing.

Power Supply Unit (PSU)

The PSU converts electricity from your wall outlet into a form that the computer’s components can use. It ensures that each part gets the right amount of power.

Optical Drive

Though becoming less common in modern computers, optical drives read and write data on CDs, DVDs, and Blu-ray discs.

Sound Card

This component processes audio information, allowing you to hear sounds on your computer, whether it’s music, a video’s audio, or the ding of a notification.

Network Interface Card (NIC)

The NIC, often integrated into the motherboard, allows computers to connect to networks, including local area networks (LAN) or the internet.

Cooling System

Computers generate heat, especially when performing intensive tasks. The cooling system, which includes fans and sometimes even liquid cooling, ensures the computer doesn’t overheat.

Expansion Slots

These are slots on the motherboard where additional cards, like a GPU or sound card, can be added to enhance the computer’s capabilities.

Ports and Connectors

These are the various inputs and outputs on a computer. They include USB ports, HDMI outputs, and audio jacks, allowing you to connect external devices like flash drives, monitors, or headphones.

Keyboard and Mouse

While technically peripherals, the keyboard and mouse are essential for interacting with a computer. The keyboard allows for data input through typing, while the mouse navigates the computer’s interface.


The monitor displays the computer’s visual output, allowing you to see everything from your desktop background to the intricate details of a video game.

Case or Tower

This is the outer shell that houses all the internal components of a computer. It not only provides protection but also ensures proper ventilation.

BIOS (Basic Input/Output System)

This is the software embedded on the motherboard. It initializes and tests system hardware components and loads the operating system when you start the computer.

CMOS Battery

A small battery on the motherboard that powers the BIOS memory, ensuring settings like the system clock’s time and date are retained even when the computer is turned off.

SSD (Solid State Drive)

A newer form of storage, SSDs are faster than traditional hard drives because they don’t have moving parts. They use flash memory to store data.

PCIe (Peripheral Component Interconnect Express)

A type of connection standard used for connecting high-speed components like graphics cards and SSDs to the motherboard.


A component that works alongside the cooling system. It’s a metal structure with fins that dissipates heat away from the CPU or GPU.

RAID Controller

This device manages hard drives grouped into RAID arrays, distributing data across multiple drives for redundancy or performance.


A device that modulates and demodulates digital signals, allowing computers to communicate over telephone lines.

Wi-Fi Card

An internal component that allows computers to connect wirelessly to networks.


A device that expands a single USB port into several, allowing multiple devices to be connected simultaneously.

I/O Shield

A metal plate that fits on the back of a computer case, providing openings for the motherboard’s ports and connectors.

Thermal Paste

A compound applied between the CPU and the heatsink to improve heat conduction.

VRM (Voltage Regulator Module)

Located on the motherboard, the VRM ensures the CPU or GPU receives the correct voltage.

M.2 Slot

A slot on the motherboard designed for M.2 form factor devices, like certain SSDs.


A set of electronic components on the motherboard that manage data flow between the CPU, RAM, and other devices.

SATA (Serial Advanced Technology Attachment)

An interface used to connect hard drives, SSDs, and optical drives to the motherboard.

External Drive Bays

Slots on the computer case where additional storage devices or optical drives can be added.
