Hello, young learners! Welcome back to Primary 1 Basic Science and Technology, Computer Studies. In our previous lesson, we learned about Computer – System Unit. Today, we’re going to learn about the Functions of Alphabetic and Numeric Keys.
Objectives
By the end of this lesson, you should be able to:
- Identify the Alphabetic and Numeric keys on a keyboard.
- State the functions of the Alphabetic and Numeric keys.
Functions of Alphabetic and Numeric Keys
The keyboard is an essential part of a computer. It allows us to type letters, numbers, and symbols. There are two main types of keys on a keyboard: Alphabetic keys and Numeric keys.
What are Alphabetic Keys?
Alphabetic keys are the keys that represent letters of the alphabet. They are used for typing words and sentences.
Some of the functions of Alphabetic keys include:
- Typing letters: We use these keys to type all the letters of the alphabet, from A to Z.
- Forming words: We combine letters to form words, such as “cat”, “dog”, and “house”.
- Creating sentences: We use words to create sentences, which express complete thoughts.
What are Numeric Keys?
Numeric keys are the keys that represent numbers. They are used for typing numbers, performing calculations, and entering data.
There are a few types of Numeric keys:
- Number keys: These keys are used to type numbers from 0 to 9.
- Function keys: These keys are used to perform specific tasks, such as saving a document or printing a file.
- Navigation keys: These keys are used to move around the screen, such as the arrow keys and the Page Up and Page Down keys.
Evaluation Questions
Now that you’ve learned about the functions of Alphabetic and Numeric keys, let’s see if you can answer these questions:
- What are the functions of the Alphabetic keys?
- How are Numeric keys useful on a keyboard?
- What are some examples of words you can create using Alphabetic keys?
- What are some examples of numbers you can type using Numeric keys?
- Can you name some other keys on a keyboard besides Alphabetic and Numeric keys?
Conclusion
We have learned that Alphabetic keys are used for typing letters, forming words, and creating sentences, while Numeric keys are used for typing numbers, performing calculations, and entering data. Remember, the keyboard is a powerful tool that allows us to communicate and create on a computer. Keep practicing and exploring the different keys on your keyboard!
