Complete Question:
Recall that with the CSMA/CD protocol, the adapter waits K. 512 bit times after a collision, where K is drawn randomly. a. For first collision, if K=100, how long does the adapter wait until sensing the channel again for a 1 Mbps broadcast channel? For a 10 Mbps broadcast channel?
Answer:
a) 51.2 msec. b) 5.12 msec
Explanation:
If K=100, the time that the adapter must wait until sensing a channel after detecting a first collision, is given by the following expression:
The bit time, is just the inverse of the channel bandwidh, expressed in bits per second, so for the two instances posed by the question, we have:
a) BW = 1 Mbps = 10⁶ bps
⇒ Tw = 100*512*(1/10⁶) bps = 51.2*10⁻³ sec. = 51.2 msec
b) BW = 10 Mbps = 10⁷ bps
⇒ Tw = 100*512*(1/10⁷) bps = 5.12*10⁻³ sec. = 5.12 msec
Answer:
False
Explanation:
Be safe and make good choices!!
True Offset printing is more expensive.
Offset printing often has a longer turnaround and is more expensive to set up, so that for short print runs, the cost per unit is higher than digital printing.
Answer:
10.
Explanation:
Binary search divides the array to be search each in half according to the value of the element.
The worst case time complexity of binary search is O(logN).
In this case the time complexity will come out to be log₂(1024)=10.
So the binary search can divide this array in half maximum of 10 times.
Hence the main loop will executes 10 times.
Answer:
a. A syntax error occurs because the method signatures do not match.
Explanation:
The method signature does not match as the method argument is wrong and so the compiler would issue a syntax error. Trying to override an inherited method from a class and not getting the method syntax correct would mean that the overide operation would not be successful as there would be a syntax error therefore it is paramount that the method argument is properly inputted in the above statement in order to successfully overide the inherited class method.
