What hardware is needed to connect the computer to the LAN?

The hardware required to connect a computer to a LAN is a network card; a network card is a basic device necessary to form a network and is used to connect computers and communication cables together. Therefore, each computer connected to a LAN needs to install a network card. .

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

To connect a computer to a LAN, the minimum hardware you need is a network card.

The network card is the basic equipment necessary to form a network. It is used to connect computers and communication cables. Therefore, each computer connected to the LAN needs to install a network card; the hub is the basic connection device of the LAN: gateway It is used to connect two different networks; the router is the main device used to interconnect the local area network and the wide area network.

Network interface controller (NIC), also known as network interface controller, network adapter, network card, or LAN receiver, is a piece of equipment designed to Computer hardware that allows computers to communicate on a computer network.

Because it has a MAC address, it belongs to layer 1 of the OSI model. It allows users to connect to each other via cable or wirelessly. Each network card has a unique 48-bit serial number called a MAC address, which is written in a ROM on the card. Every computer on the network must have a unique MAC address. No two network cards produced have the same address.

This is because the Institute of Electrical and Electronics Engineers (IEEE) is responsible for assigning unique MAC addresses to network interface controller vendors.

Network cards used to be plugged into the computer bus as expansion cards, but due to their low price and the ubiquity of the Ethernet standard, most new computers have integrated network interfaces on the motherboard.

These motherboards either integrate Ethernet functionality into the motherboard chip, or use a cheap network card connected to the motherboard via PCI (or the newer PCI-Express bus). Unless multiple interfaces are required or other types of networks are used, a separate network card is no longer needed. Even newer motherboards may have built-in dual network (Ethernet) connectors.
