Detailed explanation-1: -A NIC provides a computer with a dedicated, full-time connection to a network. It implements the physical layer circuitry necessary for communicating with a data link layer standard, such as Ethernet or Wi-Fi. Each card represents a device and can prepare, transmit and control the flow of data on the network.
Detailed explanation-2: -A network interface controller (NIC, also known as a network interface card, network adapter, LAN adapter or physical network interface, and by similar terms) is a computer hardware component that connects a computer to a computer network.
Detailed explanation-3: -Most laptop computers have both an Ethernet and a WiFi connection, while smaller devices typically only have a WiFi connection. The NIC controls both types of connections, so, whether you use an Ethernet or WiFi connection, you can use your computer for the same tasks regardless of the type of connection.
