Parts of computer for kids (9+)

Last Updated on September 1, 2022 by Circular Guru

Parts of  computer for kids include the monitor, keyboard, mouse, printer, CPU, motherboard, memory, storage, and graphics card.

Most computer users are familiar with the most common parts of a computer: the motherboard, CPU, RAM, hard drive, and graphics card. But what are those other parts and how do they work together to make a computer run? In this article, we’ll take a closer look at each part and what it does.

Personal computers come with a variety of different components. Each component plays an important role in how the computer operates and is essential for tasks like browsing the internet, writing documents, or playing video games.

Some of the most common components are the monitor, keyboard, mouse, printer, motherboard, processor, RAM, graphics card, hard drive, and optical drive.


Monitors are a type of computer display that is used to output video and images. There are two main types of monitors, CRTs, LCDs, and LEDs.

LCDs (liquid crystal displays) are the most common type of flat-screen monitor. They use a thin layer of crystal liquid to create images and are available in sizes ranging from 10 inches to more than 60 inches.

LED is a newer type of LCD monitor that uses light-emitting diodes (LEDs) instead of fluorescent tubes to backlight the display. This results in a thinner monitor with improved image quality and energy efficiency.

CRTs (cathode ray tubes) were once the most common type of monitor, but they are now largely obsolete. They use an electron beam to scan an image onto a phosphor screen, resulting in a bulky, heavy monitor that consumes a lot of energy.

Plasma monitors were once popular, but have been largely replaced by LCDs and LEDs.


A computer keyboard is a device used to enter text into a computer. There are several different types of keyboards, including the traditional desktop keyboard, the laptop keyboard, and the virtual keyboard. The traditional desktop keyboard has a number of different keys, including the alphanumeric keys, the function keys, and the arrow keys.

The laptop keyboard is similar to the desktop keyboard, but it is smaller and has fewer keys. The virtual keyboard is a software program that allows you to enter text using your mouse or trackpad.

A mouse is a small pointing device that is used to control the movement of a cursor on a computer screen. It is typically connected to the computer via a USB port, but can also be connected wirelessly. The mouse has two main buttons and a scroll wheel in the middle. It can be used for many purposes, such as clicking on icons, selecting the text, and scrolling through documents or websites.


Printers are output devices that take digital data and create a hard copy of the document on paper. In personal and small business environments, printers are essential for printing documents, photos, and other items. Printers come in a variety of types, including inkjet, laser, and dot matrix. They also come in a range of prices, with some models costing less than $100 and others costing more than $1,000.

There are three main types of printers: dot-matrix printers, ink-jet printers, and laser printers. Each has its own set of benefits and drawbacks.

Dot-matrix printers are the oldest type of printer. They work by striking an ink-soaked cloth ribbon against a series of pins to create characters on a sheet of paper. This type of printer is very cheap, but the print quality is not very good.

Ink-jet printers work by spraying tiny droplets of ink onto the paper. This results in high-quality prints, but they are also the most expensive type of printer.

Laser printers work by heating up toner particles and then blasting them onto the paper. They produce high-quality prints at a relatively low cost, but they are also the slowest type of printer.


A motherboard, sometimes called a mainboard, is the foundation of a computer. It is the biggest board in most computers and it houses many of the key components that make your computer run.

The motherboard contains the CPU, RAM, graphics card, and ports for connecting peripherals. It also includes connectors for attaching drives (such as hard drives and optical drives), fans, and other components.

Motherboards come in a variety of shapes and sizes, depending on the form factor. ATX and microATX form factors are the most prevalent. ATX motherboards are larger than microATX motherboards, so they can accommodate more components. However, microATX motherboards are more common because they are smaller and fit in tighter spaces.


The central processing unit (CPU) or processor is the brain of a computer. It is an integrated electronic circuit that does the calculations that are needed for the computer to work.

The processor is mounted on a small circuit board called a motherboard. The motherboard also contains other key components such as Random Access Memory (RAM), the graphics card, and the hard drive.

The processor is usually described by its clock speed, which is measured in gigahertz (GHz). A higher clock speed means that the processor can perform more calculations per second. Some of the latest processors can reach speeds of 5GHz or more.

The processor is surrounded by a heatsink and fan to keep it cool. If it gets too hot, it can damage or even destroy the computer.


A RAM is a computer component that stores data temporarily. This allows the computer to access the information quickly, which is why it’s called random access memory. When you turn off your computer, the data in the RAM is erased.

Graphics Card

A computer’s visual memory can be improved with a device called a graphics card. A computer’s graphics card helps it show pictures, movies, and games on the monitor.

The main goal of a graphics card is to boost the system’s 3D performance by making geometry calculations and rendering go faster. One could also use more than one graphics card in SLI or Crossfire mode to improve their 3D gaming experience even more.

Hard Drives

A hard drive is a device that stores digital data on a computer. It is a component of the computer’s storage system, which also includes the motherboard, Random Access Memory (RAM), and other devices.

The hard drive is usually a metal cabinet that sits inside the computer case. Inside a traditional hard drive are one or more spinning disks – called platters – on which data is stored.

There are three main types of hard drives: hard disk drives, solid-state drives, and NVME solid-state drives. 

A hard disk drive is a storage device that uses magnetic disks to store data. They are the most common type of hard drive and are usually less expensive than other types of hard drives. Hard disk drives usually have a lower storage capacity than other types of hard drives but offer faster data access speeds. 

A solid-state drive is a storage device that uses flash memory to store data. They are typically more expensive than other types of hard drives but offer significantly faster data access speeds and longer battery life. Solid state drives typically have a lower storage capacity than other types of hard drives. 

NVME solid-state drives are a newer type of solid-state drive that offers even faster data access speeds than traditional solid-state drives.


Computer basic, a computer is made up of five main parts: the monitor, the keyboard, the mouse, the CPU, and the system unit. Each of these parts has a specific purpose in order for the computer to function. By understanding what each part does, you can troubleshoot problems and maintain your computer more effectively.
