An extension cable is a type of cable that extends the reach of a connection between devices or peripherals. It provides additional length to existing cables, allowing devices to be placed further apart while maintaining connectivity.

Extension cables are available in various types to suit different needs. Common types of extension cables include USB, HDMI, Ethernet, power, audio, and video extensions. These cables allow for the extension of connections in various scenarios, providing flexibility and convenience.

The primary purpose of an extension cable is to extend the length of existing cables, accommodating different setups and distance requirements. By using an extension cable, devices can be placed at a greater distance from each other while still being connected.

Extension cables offer flexibility in device placement and organization, reducing cable clutter and providing a neater and more organized setup. They allow for easy cable management by extending cables to desired locations, making it easier to arrange devices and cables in a way that suits the user's needs.
