What are the advantages and disadvantages the mouse?

Answer 1

As opposed to having a proprietary bus mouse (only found in very old computer systems), a serial mouse allows you to use a standardized interface and protocol, meaning you can easily replace the mouse if it breaks. The disadvantages of a serial mouse are:

1. It occupies the serial port, barring it from use for other devices, such as a modem. If you only have one serial port and no internal modem, you cannot use a dial-up modem and the mouse at the same time.
2. They are not always detected automatically or correctly by the operating system.
3. They can't be used with many newer computers without purchasing an adapter, as newer computers often lack a serial port.
4. They were introduced at a time when few optical (laser) mice were available. As such, you are usually limited to only ball mice, which some people do not like.
5. They often have lower / fixed acceleration speeds, meaning it takes them longer to move across the screen or they require a larger movement of the mouse.
