A USB Wi-Fi adapter or dongle is used to connect a computer or laptop to a Wi-Fi network. If your computer does not have an integrated network card, this type of device lets you connect without the need to install a card in your computer.
These devices are called USB dongles and add features to the computer or machine that were not built in by the manufacturer. This can include the ability to connect to wireless networks, transfer data from the computer to the dongle, and increase a system's security.
