Contention slot used to make reservation for transmitting by placing a 1 if station wants to transmit is _______________.
A. 
B. 
Binary countdown protocol
C. 
Limited contention protocol
D. 
Carrier Sense Multiple Access with Collision Detection
2.
Initially all the nodes are allowed to try to aquire the channel, and if it is able to aquire the channel, it sends its frame. If there is collision then the nodes are divided into two equal groups and only one of these groups compete for slot 1. If one of its member aquires the channel then the next slot is reserved for the other group.

A. 
B. 
Binary countdown protocol
C. 
Limited contention protocol
D. 
Carrier Sense Multiple Access with Collision Detection

17.
When a central station is in range of two stations but these are out of each other's range and cannot sense each other's transmission, thus, one of the two stations transmitting would collide at the central station but not sensed by the other station from these two. The two stations are _____________.
A. 
B. 
C.
