Hi, young learners! Welcome back to Primary 4 Basic Science And Technology, Computer Studies. In our previous lesson, we learned about Data. Today, we’re going to learn about Computer Hardware.
Objectives
By the end of this lesson, you should be able to: * Define computer hardware. * List examples of computer hardware.
Computer Hardware
Computer hardware refers to the physical parts of a computer, like the monitor, keyboard, and mouse.
What is Computer Hardware?
Computer hardware is the tangible, physical components of a computer system. These are the parts you can touch and see. They are responsible for carrying out the instructions given by the software.
Examples of Computer Hardware
Some of the main components of computer hardware include:
- Monitor: This is the screen that displays the output of the computer.
- Keyboard: This is used to input text and commands into the computer.
- Mouse: This is used to control the cursor on the screen and interact with the computer.
- Printer: This is used to print documents and images from the computer.
- Central Processing Unit (CPU): This is the brain of the computer, responsible for processing information.
- Hard Disk Drive (HDD): This is where the computer stores its data and programs.
- Random Access Memory (RAM): This is temporary memory that the computer uses to store data that is being actively used.
- Motherboard: This is the main circuit board of the computer, connecting all the other components.
- Graphics Card: This is responsible for processing and displaying images on the monitor.
- Sound Card: This is responsible for playing sound from the computer.
- Network Card: This allows the computer to connect to a network.
Evaluation Questions
Now that you’ve learned about computer hardware, let’s see if you can answer these questions:
- What are the physical parts of a computer called?
- Can you name five examples of computer hardware?
- Why is it important to understand computer hardware?
- What is the function of the CPU?
- What is the difference between RAM and HDD?
Conclusion
We have learned that computer hardware refers to the physical parts of a computer. These parts work together to allow us to use computers for various tasks. Don’t forget to check the comments section if you have any questions, and use the navigation to move to the next lesson. See you in the next lesson!
