The PS/2 ports on a computer are used for which types of devices?

PS/2 ports are primarily used for connecting input devices, specifically a keyboard and a mouse. These ports were widely utilized in older computer systems for their simplicity and versatility in connecting these types of peripherals.

The design of PS/2 ports allows for a direct and reliable connection between the computer and input devices. When a mouse is connected via a PS/2 port, it can communicate effectively with the computer, facilitating user interaction. The other options listed—printer, monitor, and scanner—do not utilize PS/2 connections. Printers typically connect via USB or parallel ports, monitors connect via VGA, HDMI, DisplayPort, or similar video ports, and scanners often connect through USB or network connections. This specificity of the PS/2 ports for input devices emphasizes their role in user input rather than peripheral devices involved in output or data processing tasks.
