Suppose an 802.11 b station is configured to always reserve the channel with the rts/cts sequence.

suppose this station suddenly wants to transmit 1,000 bytes of data, and all other stations are idle at this time.

as a function of sifs and difs, and ignoring propagation delay and assuming no bit errors, calculate the time required to transmit the frame and receive the acknowledgment.

3. (5 points) describe what would be printed by the code below or what error would occur. const char* cstr = "0123456"; const char* ptr = & cstr[4]; cout < < ptr[-1] < < ptr < < endl; 1 4. (5 points) theseus has been trapped in a maze with a minotaur, which is trying to capture him. each round, theseus and the minotaur move through the maze; theseus towards the exit, and the minotaur towards theseus. theseus can move in any of the four cardinal directions, or he can wait for a round to see how the minotaur moves. write code that creates a data type to represent the possible moves that theseus could make.
