Chapter 2 — Computer Parts
A computer has different parts and devices that help us use it. Each part has a different job. Some parts help us see information, some help us enter information, and others help us hear or print information.
In this chapter, you will learn about common computer parts such as the monitor, keyboard, mouse, speakers and printer. You will also learn about some other devices that can be connected to a computer.
Why This Chapter Matters
Knowing the different parts of a computer helps us understand how a computer works and how to use it correctly. Each device has a specific purpose, so recognising the right part helps us choose the correct device for a task.
Different computer parts help us perform different tasks.
Learning about these devices will prepare you to use the mouse, keyboard and other computer equipment safely and confidently.
What You Will Learn
- What a monitor is and what it does.
- What a keyboard is and how it is used.
- What a mouse is and what it does.
- How speakers are used with a computer.
- What a printer does.
- Examples of other common computer devices.
- Why different computer parts have different jobs.
Before You Begin
Before starting this chapter, you should know that a computer is made up of different parts and devices. You should also remember that each part can have a different purpose.
You do not need to remember every technical detail. The goal is to recognise common computer devices and understand their basic uses.
Understanding the Learning Sequence
The lessons introduce the most common computer parts one at a time. You will first learn about the monitor, followed by the keyboard and mouse. You will then learn about speakers, printers and other common devices.
This sequence helps you understand the purpose of each device before learning how to use some of them in later chapters.
