In this CompTIA Network+ training video, we’ll be looking at computer connectivity and two devices that allow a computer system to connect to the Internet or other network media. The two devices we’ll be looking at are modems and Network Interface Cards (NIC), which are two ways computers can connect to the Internet.
Modems are used for dial-up connections (up to 56kbps) over standard analog telephone lines. Modems, at least in this definition, can be integrated onto a system’s motherboard, an internal expansion card, or an external peripheral device.
Network Interface Cards are used similarly to connect systems to physical network media. This could be the Internet, local network, etc. They can be integrated onto a system’s motherboard or an internal expansion card.
