We just learned about the Sound Card.
Another part of a computer is the Network Card, also called a network interface controller (NIC), network adapter or LAN adapter, where LAN means local area network.
When you are on your computer and you want to connect to the internet to send a message, chat or play games, you use the computer's network card.
These days the network card is just part of the computer's motherboard, but a long time ago you had to buy a special card for your computer.
With wifi and cell phones it is very easy now to get on a network and share messages, but it used to be a lot of work!
