Hi, Primary 3 students! Welcome back to Basic Science & Technology, Computer Studies. In our previous lesson, we learned about computer keyboards and mice. Today, we’re going to learn about different types of keyboards.
Objectives
By the end of this lesson, you should be able to:
- Mention different types of keyboards.
- Identify different arrangements of keys.
- Mention the different keys on the keyboard, including alphanumeric keys, function keys, numeric keypad, system keys, and navigation keys.
Types of Keyboards
There are various types of computer keyboards, each with its own unique features. Some of these types include:
- QWERTY Keyboard: This is the most common type of keyboard, named after the first six letters in the top row of keys. It’s used in most computers and laptops.
- Dvorak Keyboard: This keyboard layout is designed to be more efficient for typing, with frequently used letters placed closer to the home row. It’s less common than the QWERTY layout.
- Ergonomic Keyboard: These keyboards are designed to reduce strain on the wrists and hands. They often have a split design or curved keys.
- Gaming Keyboard: These keyboards are designed for gamers, with features like extra keys, customizable lighting, and faster response times.
- Virtual Keyboard: This is a keyboard displayed on a computer screen, often used on touchscreens or devices without physical keyboards.
Identifying Keys
The keys on a keyboard are grouped into different categories, each with a specific function. Some of these categories include:
- Alphanumeric Keys: These keys include letters, numbers, and punctuation marks.
- Function Keys: These keys are located at the top of the keyboard and are used to perform specific tasks, such as printing, saving, or opening files.
- Numeric Keypad: This is a separate section of keys on the right side of the keyboard, used for entering numbers quickly.
- System Keys: These keys are used to perform system-related tasks, such as switching between windows or restarting the computer.
- Navigation Keys: These keys are used to move the cursor around the screen, such as the arrow keys, Page Up, and Page Down keys.
- Special Keys: These keys are used to perform specific actions, such as the space bar, Enter key, and Shift key.
Key Arrangements
The arrangement of keys on a keyboard can vary depending on the type of keyboard and its intended use. The most common arrangement is the QWERTY layout, but other layouts like AZERTY, DVORAK, and QWERT are also used. The arrangement of keys can affect typing speed and efficiency.
Evaluation Questions
Now that you’ve learned about different types of keyboards, let’s see if you can answer these questions:
- What are two types of computer keyboards?
- What are some of the different groups of keys found on a keyboard?
- Why is it important to know the arrangement of keys on a keyboard?
- What are some of the features of a gaming keyboard? 5. What is a virtual keyboard and when is it used?
Conclusion
Today, we learned about different types of keyboards, the different keys on a keyboard, and how they are arranged. Knowing about different keyboards and their features is important because computers are an integral part of our daily lives. Keep exploring and learning about computers! See you in the next lesson!
