COMPUTER FUNDAMENTALS

Detailed explanation-1: -The connected ethernet cable can be plugged into a network switch in order to connect your computer to other devices within a network, for example, other computers, servers, printers, security cameras, etc. The cable can also be plugged into a router to connect the computer to the internet.

Detailed explanation-2: -A wired NIC usually connects a node onto a network with an Ethernet or fiber optic cable; a wireless NIC often comes with a small antenna, which uses radio waves to communicate with the access point to get involved in a wireless network.

Detailed explanation-3: -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-4: -Working as an interface at the TCP/IP layer, a NIC card can transmit signals at the physical layer and deliver data packets at the network layer. No matter what layer the network interface controller lies, it acts as a middleman between a computer/server and a data network.

Detailed explanation-5: -A network interface card (NIC) is a hardware component without which a computer cannot be connected over a network. It is a circuit board installed in a computer that provides a dedicated network connection to the computer. It is also called network interface controller, network adapter or LAN adapter.
