What is the difference between a USB plug-and-play connection and a PS/2 port connection?

The PS/2 port connection predates the USB plug-and-play connection but is still available for computer users who prefer reduced latency issues and the n-key rollover ability for unlimited simultaneous key presses. Connecting a keyboard via a USB connection provides the flexibility to switch, disconnect and reconnect a keyboard.

What if my computer does not have an available USB port?

You can purchase a PS/2 to USB adapter for a USB keyboard.

How do I determine the best wired keyboard for my needs?

Ergonomic keyboards help reduce risk of injury, increase comfort and range from a palm rest to a curved keyboard design. Backlit keyboards are useful when working or gaming in dimly lit areas. Mechanical keyboards increase speed and durability for gaming and high usage due to the individual key switches and strong metal springs.
