41. Why is the NIC considered the “gatekeeper”?
ANSWER:
The NIC’s responsibility is to examine every frame that is received and either allow it access
to the computer or reject it. In order for the frame to be accepted, the destination MAC
address must match the NIC’s MAC address, or it is refused. There are two exceptions to this
rule. If the destination MAC address is a broadcast, then the NIC accepts it. If the NIC is put
in promiscuous mode, then it will accept all frames.

42. What are the major differences between a hub and a switch?
ANSWER:
The major difference is that switches are intelligent. They examine each frame that they
receive for the destination MAC address and then send the frame out the correct port for that
address. A hub simply accepts a frame from one of its ports and then sends it out all ports. A
switch also keeps a table of MAC addresses so that it knows where to send a frame. Because
a switch can control where it sends a frame, devices that are connected to a switch can
communicate at the same time, allowing each device to access the full network bandwidth.
With a hub, only one device can transmit at a time so the bandwidth is shared among all
connected devices. Also, because a switch controls the flow of frames, there is little chance
of a collision. In a hub, collisions might occur frequently when under heavy use.
