What is a NIC?
During an interview for a network engineering position at Cisco, you will be asked about the various hardware and software components of a network. Some of these will be very basic questions, while others may be more complex and detailed. This is an example of a simple one. Interviewers can ask these questions at any time during the interview. The best way to be prepared for these types of questions is to review the components of a network just before the interview so that they are fresh in your mind.
"A NIC is a Network Interface Card. It is sometimes known as a network adapter or ethernet card. It is a device installed in a computer that enables the computer to be connected to a network. Each NIC has a unique media access control, or MAC address, which helps identify the computer on a network."
