What are two differences between switches and hubs? (Choose two.)
A . Switches are slower than hubs because of the extra addressing functions that switches perform.
B . Switches send data to all of the computers that are connected to them for efficiency.
C . Switches are capable of sending and receiving data at the same time.
D . Switches identify the intended destination of the data that they receive.
Answer: AD
Explanation:
Hubs repeat everything they receive and can be used to extend the network. Switches control the flow of network traffic based on the address information in each packet. A switch learns which devices are connected to its ports (by monitoring the packets it receives), and then forwards on packets to the appropriate port only. This allows simultaneous communication across the switch, improving bandwidth.
