There are (a) types of frequency bands used on wireless routers.
The (a) GHz range is a longer frequency that can travel through physical barriers like walls and floors.
The (a) GHz range has a faster transfer rate, allowing it to move data more quickly.
This allows the data stream to be more unpredictable from outside the network, making it harder to intercept and eavesdrop on.
Direct sequence spread spectrum
Orthogonal frequency division multiplexing
Frequency hopping spread spectrum
it can avoid interference if certain channels are blocked within that frequency.
Direct sequence spread spectrum
Frequency hopping spread spectrum
Orthogonal frequency division multiplexing
Makes the transmitted bandwidth signal wider than the data stream needs.

Wireless networks use (a) multiple access/collision avoidance (CSMA/CA) to control access to avoid (rather than detect) collisions.
Wireless communication operates in (a) (shared two-way communication).
The sending device listens to the media to make sure that no other device is (a) .
If no other device is transmitting, the sending device (a) a request to send (RTS) message to the receiver or AP.
The receiving device responds with a (a) (CTS) message.
The sending device (a) the data.
After the time interval specified in the RTS and CTS has (a) , other devices can start the process to attempt to transmit.
A wireless network interface card sends and receives radio signals.
True
False
A wireless bridge connects three APs into a single network or connects a wireless AP to a wired network.
True
False
Devices must take turns using the transmission channel.
True
False
