There are many types of computer mice that differ in size, shape and function. A wired mouse is a good choice for users who want fast response time and a stable connection. There are models with PS/2 connector and models with USB connector. However, a wireless mouse is more convenient and offers more freedom of movement. There are also Bluetooth mice that work without a cable or dongle. Some mice have additional features like programmable buttons or a scroll wheel. They come in different sizes and shapes to accommodate different hand sizes and grip styles.
