A network interface card contains an Ethernet adapter for connecting the computer to a wired network. A NIC can provide a faster, more reliable and more secure connection than a wireless network card. However, NICs are less portable and often less convenient than using a wireless radio to access the Internet. That’s why many computers, including laptops, provide both a NIC and a wireless radio, which gives you the option to choose the way you connect to the Internet depending on the circumstances.
