Q. We have categorized access methods into _______ groups.

View solution

Q. In ___________ methods, no station is superior to another station and none is assigned the control over another.

View solution

Q. In ______, the chance of collision can be reduced if a station senses the medium before trying to use it.

View solution

Q. __________ augments the CSMA algorithm to detect collision.

View solution

Q. In ________, a station monitors the medium after it sends a frame to see if the transmission was successful. If so, the station is finished. If, however, there is a collision, the frame is sent again.

View solution

Q. To avoid collisions on wireless networks, ________was invented.

View solution

Q. In _______, collisions are avoided through the use of three strategies: the interframe space, the contention window, and acknowledgments.

View solution

Q. In _______ methods, the stations consult one another to find which station has the right to send.

View solution

Q. In _______ methods, a station cannot send unless it has been authorized by other stations.

View solution

Q. There are ______ popular controlled-access methods.

View solution

Q. In the ________ method, a station needs to make a reservation before sending data. Time is divided into intervals.

View solution

Q. In the _____ method, time is divided into intervals. In each interval, a reservation frame precedes the data frames sent in that interval.

View solution

Q. In the ______ method, all data exchanges must be made through the primary device even when the ultimate destination is a secondary device.

View solution

Q. In the _______ method, the primary device controls the link; the secondary devices follow its instructions.

View solution

Q. In the _______ method, the stations in a network are organized in a logical ring.

View solution

Q. In the _______ method, each station has a predecessor and a successor.

View solution

Q. In the _________ method, a special packet called a ______ circulates through the ring.

View solution

Q. _________ is a multiple-access method in which the available bandwidth of a link is shared in time, frequency, or through code, between different stations.

View solution

Q. There are ________ channelization protocols.

View solution

Q. In ________, the available bandwidth is divided into frequency bands.
