- BA MAC address is represented by binary digits that are organized in pairs.
- AA MAC address is a number in hexadecimal format that is physically located on the NIC.
5Which statement about NICs is accurate?
- AThe NIC plugs into a USB port and provides a port for connecting to the network.

8Which of the following statements about the functions of a hub are accurate? (Choose two.)
- AA hub extends an Ethernet LAN.
- BA hub reduces the size of a collision domain.
- CAdding a hub eliminates the need for users on a network segment to compete for the same bandwidth.
- DA hub is a data link layer device.
- EA hub amplifies the data signal before retransmitting it.

9Which of the following statements best describe collisions? (Choose three.)
- ACollisions occur when two or more stations on a shared media transmit at the same time.
- BLarger segments are less likely to have collisions.
- C. In a collision, the frames are destroyed, and each station in the segment begins a random timer that must be completed before attempting to retransmit the data.
- DAdding a hub to a network can improve collision issues.
- ECollisions are by-products of a shared LAN.
- FMore segments on a network mean greater potential for collisions.
