Wired connections include all connection methods that require physical contact between the device and the computer using a cable. This is most often done with the classic USB-A connector, but less commonly with the USB-C variant. Although this form of connection usually offers a faster and more reliable connection, it can restrict freedom of movement and contribute to desk clutter, especially due to the length of the cable, which is often around 1.8 metres.

USB (Universal Serial Bus) is a standard interface for connecting various peripheral devices to computers. It is known for its versatility, speed and ability to transfer both data and electricity.

Anti-ghosting is a feature of keyboards that allows multiple simultaneous keystrokes to be recorded flawlessly. This feature is essential for gamers and professional users who require fast and accurate inputs, for example for using complex keyboard shortcuts. "Ghosting" occurs when multiple keys are pressed simultaneously and the keyboard is unable to correctly record each press, which can lead to incorrect or unrecorded input. Anti-ghosting keyboards are designed to prevent this problem. They use advanced circuit designs or individual diodes for each key, this ensures that every keystroke is correctly and reliably registered no matter how many keys are pressed simultaneously.

Optical mice use LED light and a sensor to detect motion on the surface. They are popular for their reliability and high accuracy in common applications. They work well on surfaces where light reflects well, meaning if you have a shiny or rough surface, it's better to use a mouse pad. Compared to laser mice, they can have a lower DPI resolution.

The RGB backlighting of the mouse allows users to customize the color lighting from a wide range of colors. For gaming mice, this type of backlighting can be synchronized with other gaming equipment such as keyboards or headsets.
