A mouse is typically connected to the serial port of a computer.

A joystick is a type of input device that is commonly used to play computer games. It allows the user to control the movement of objects on the screen by manipulating a stick or lever. This makes it an ideal device for gaming, as it provides more precise control than a keyboard or mouse. While keyboards, mice, and touch screens can also be used as input devices for gaming, a joystick is specifically designed for this purpose.

Explanation
A joystick is not an input device because it is primarily used for controlling movement in video games or flight simulators. It does not provide any means for inputting data or commands into a computer system. In contrast, a keyboard allows the user to input text and commands, a printer is an output device that produces hard copies of documents, and an optical character reader is a device that can scan and convert printed text into digital data.

Explanation
The keyboard is used to type in a computer. It is an input device that allows users to input text, numbers, and commands into the computer. The keyboard consists of a set of keys, including letters, numbers, symbols, and function keys, which are pressed to input the desired characters or commands. It is an essential tool for communication and data entry on a computer. The mouse, CPU, and ROM are not used for typing in a computer.
