Did you know that the first computer mouse was made of wood and had only one button? A computer mouse may appear to be a simple device, yet it has an important effect on how we use computers every day. In this article, we’ll explain what is mouse, how it works, and why it’s so useful for people of all ages.
What is a Mouse?
A mouse is a small device that lets you move the cursor on a computer screen. It helps you navigate files, websites, and programs by clicking, selecting, and scrolling. It makes using a computer quicker and easier by allowing you to move around and choose what you want to do.

History of the Mouse
Douglas Engelbart invented the computer mouse in 1964. His first version was a wooden box with two wheels and a single button. It was nothing like the slick styles we see now. The mouse developed popularity in the 1980s after Apple began utilizing it with their computers. Later, other corporations integrated the mouse into their systems. It progressed from having a ball inside (to track movement) to using laser and optical sensors. Today’s mice are faster, more accurate, and typically wireless, making them more convenient to use at home, work, or school.
Parts of a Mouse
A computer mouse has a few basic parts that help it work smoothly:
- Buttons: Most mice have two major buttons: left and right. You can use these to click, select, and open items on your screen. Some mice include additional buttons for specific functions.
- Scroll Wheel: Located between the buttons, the scroll wheel lets you move up and down on a page quickly. Some wheels can also be clicked like a button.
- Body: This is the main part you hold. It is shaped to fit comfortably in your hand.
- Sensor: On the bottom of the mouse, the sensor detects movement. Older mice used a rolling ball, but today’s mice use optical or laser sensors for more accuracy.
- Cable or Wireless Receiver: Some mice connect to the computer with a cable, while wireless mice use a small receiver or Bluetooth to connect without wires.

Types of Mouse
There are several types of computer mice, each designed for different needs:
1. Wired Mouse
This mouse connects to your computer with a cable. It’s reliable and doesn’t need batteries. Many people use wired mice for gaming or office work.
2. Wireless Mouse
A wireless mouse connects without cables, usually through Bluetooth or a small USB receiver. It gives you more freedom to move, but it needs batteries or charging.
3. Optical Mouse
This type uses a light sensor to detect movement. It works well on most flat surfaces and is very common today.
4. Laser Mouse
A laser mouse uses a laser sensor to track movement with high accuracy. It performs effectively on practically any surface, even glass and glossy desktops, where traditional mice may struggle. This makes it an excellent alternative for users who want precise control, such as gamers, designers, and professionals.
5. Ergonomic Mouse
An ergonomic mouse is designed to fit your hand comfortably and relieve strain when using it. It helps to avoid wrist and finger pain during hours of computer usage. This mouse is suitable for persons who frequently use computers and wish to minimize discomfort or injury.
