Parts of Computer with Their Fucntions and Images
CPU (Central Processing Unit):
The CPU is the brain of the computer. It handles all instructions and calculations. Everything you do on your computer goes through the CPU.
Motherboard:
This is the main circuit board. All the computer parts connect to it, like the CPU, RAM, and hard drive. It holds everything together and makes sure they work smoothly.
RAM (Random Access Memory):
RAM is like the computer’s short-term memory. It helps the computer store data temporarily while you’re working on something, like opening apps or files. The more RAM, the faster your computer works
Hard Drive (HDD/SSD):
The hard drive stores all your files, programs, and the operating system (Windows, macOS). SSDs are faster than HDDs, meaning programs and files open quicker.
Power Supply Unit (PSU):
The PSU gives power to all the computer parts. It takes electricity from the wall and turns it into the type of power the computer parts need to run.
Graphics Processing Unit (GPU):
The GPU handles images and videos. If you play games or work with graphics, the GPU makes sure everything looks smooth and clear.
Optical Drive (DVD/CD):
This is where you insert CDs or DVDs. It reads or writes data from/to the discs. Nowadays, many computers don’t come with this drive.
Sound Card:
The sound card allows the computer to produce sound. It connects to speakers or headphones so you can hear audio from music, videos, or games.
Cooling System (Fans, Heatsinks, Liquid Cooling):
The cooling system keeps the computer from getting too hot. Fans or liquid cooling systems lower the temperature so the computer works properly and doesn’t overheat.
Case (Chassis):
The case holds all the computer parts inside. It also protects them from dust and damage.
Keyboard:
The keyboard lets you type letters, numbers, and symbols. You use it to write emails, search the internet, or do any typing tasks.
Mouse:
The mouse allows you to move the pointer on the screen. You can click, drag, and scroll to interact with the computer.
Monitor:
The monitor shows you what’s happening on the computer. It displays text, images, and videos, like your computer’s TV screen.
Network Interface Card (NIC):
The NIC connects your computer to the internet or other networks. You can use a cable (Ethernet) or Wi-Fi to get online.
USB Ports:
USB ports let you connect devices like flash drives, printers, and external hard drives to your computer.
HDMI/Display Ports:
These ports connect your computer to a monitor or TV, allowing you to display videos and images on a larger screen.
Ethernet Port:
The Ethernet port connects your computer to the internet using a wired connection. It’s faster and more stable than Wi-Fi.
Speakers:
Speakers produce sound from your computer. You can listen to music, watch videos, or hear notifications.
Webcam:
The webcam lets you make video calls or record videos. It’s useful for online meetings or chatting with friends and family.
Touchpad (for laptops):
The touchpad acts like a mouse on a laptop. You can move the pointer by sliding your finger on it.
BIOS/UEFI:
The BIOS/UEFI is a special program that helps start your computer. It checks all the hardware and gets everything ready before the operating system (Windows, macOS) starts.
Expansion Slots:
Expansion slots allow you to add extra parts, like more memory or a better sound card, to improve your computer’s performance.
Printers:
Printers let you print documents, photos, or anything you want on paper from your computer.
Power Cables:
Power cables connect your computer and other devices to the power outlet, providing the electricity they need to work.
Wi-Fi Adapter:
The Wi-Fi adapter connects your computer to the internet without wires. It allows you to use the internet anywhere within range of a Wi-Fi network.
