FAQs on Printable Worksheet Solutions: Computer Mouse - International Computer Science Olympiad Class 1

1. What is a computer mouse and how does it work?
Ans. A computer mouse is a handheld input device used to interact with a computer. It typically has two buttons and a scroll wheel. When the mouse is moved across a flat surface, it detects movement and translates it into cursor movement on the screen. The buttons allow the user to select and interact with items on the computer.
2. What are the different types of computer mice available?
Ans. There are several types of computer mice, including mechanical mice, optical mice, laser mice, and wireless mice. Mechanical mice use a ball to detect movement, while optical and laser mice use light sensors. Wireless mice connect to the computer via Bluetooth or a USB receiver, providing more freedom of movement.
3. How do you clean a computer mouse?
Ans. To clean a computer mouse, first unplug it or turn it off if it's wireless. Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the exterior. For the optical sensor, use a cotton swab to gently clean the area. Avoid using harsh chemicals, as they can damage the mouse.
4. Why is it important to use a mouse pad?
Ans. A mouse pad provides a smooth surface for the mouse to glide over, improving accuracy and responsiveness. It can also protect the mouse's bottom from wear and tear. Additionally, a mouse pad can help prevent dust and dirt from interfering with the mouse's sensors.
5. What are the benefits of using a computer mouse over a touchpad?
Ans. A computer mouse offers several advantages over a touchpad, including greater precision and comfort, especially during prolonged use. It allows for quicker navigation and can reduce hand fatigue. Additionally, a mouse often has additional buttons that can be programmed for specific functions, enhancing productivity.
