A stable and flexible IT network should sit at the heart of virtually every modern business. Stability means security and the peace of mind of knowing that the data your business depends upon is safe, while flexibility means that the network you use can change and grow as your business does. Network cards have a vital part to play in this, and understanding why means answering the question: What is a network card?

IT Connectivity

In simple terms, a network card is used to build and expand the connectivity of your IT network. It goes without saying that the more devices and users that can connect to your network, the more effectively your business will function. In some cases, the answer to the question what is a network card is that it’s a relatively simple Ethernet PCI network card which connects a PC to a switch or router.

More advanced are those networking routers or switches which include Network Module Interface cards such as WIC cards, HWIC. HWIC stands for High speed WAN Interface Card, and WAN means Wide Area Network. These cards allow a router to connect and transmit data over a wider area.
