A USB to Ethernet Adapter is a device that allows you to connect an Ethernet cable (typically for wired internet access) to a computer or device through a USB port. This is commonly used when a computer lacks a built-in Ethernet port, or when you need to add additional Ethernet ports to your system. These adapters are often used for laptops, ultrabooks, or mini-PCs that only have USB ports but need a stable wired network connection.

The USB to Ethernet Adapter Windows driver is software that enables Windows to recognize and use the adapter. Without the proper driver, the adapter may not function correctly, and you may not be able to establish a wired connection.
