Question 5. Fill in the blank(s)

A Network Interface Controller converts data into a format suitable for transmission over the [[network medium]].

Question 6. Fill in the blank(s)

NICs operate primarily at the [[Data Link Layer]] of the OSI model.

Question 7. Fill in the blank(s)

The unique hardware address of a NIC used to route data is called the [[MAC address]].

Question 8. Fill in the blank(s)

Ethernet NICs connect devices using [[Ethernet cables]].

Question 9. Fill in the blank(s)

The ability of a NIC to send and receive data at the same time is called [[full-duplex]] mode.

Question 10. What is the main purpose of a Network Interface Controller (NIC)?

To allow a computer or device to connect to a network and transmit and receive data.

Question 11. Name two types of NICs used for different connection methods.

Ethernet NICs (wired) and Wireless NICs (wireless).

Question 12. What function does TCP Offloading provide in a NIC?

It offloads certain processing tasks from the CPU to the NIC to improve performance.

Question 13. Why might a network use Fiber Optic NICs instead of Ethernet NICs?

To achieve higher data transfer speeds and longer transmission distances.

Question 14. Explain what VLAN support in a NIC enables.

It allows the NIC to be used in virtual LANs, segmenting network traffic for security and efficiency.
