Answer of the question

Question A

When B is sending to A, what other communications are possible?

The answer is

In that case B packet will not seen by D.other nodes cannot send to D because the packet from this nodes will interface the packet from B to A.other communication is not possible at the same time.

Question B

When A is sending to C, what other communications are possible

Answer is

when A sending to c in that case all station will seen as packet.it will interface with the receipt of any other packet by any other station.so no other communication is possible in that time.

Consider an overlapping set of four circles A, B, C, D. One would like to position the circles so that every possible subset of the circles forms a region, e.g., four regions each contained in just one (different) circle, six regions formed by the intersection of two circles (AB, AC, AD, BC, BD, CD), four regions formed by the intersection of three of the four circles, and one region formed by the intersection of all four circles. Prove that it...

There are four persons A, B, C, D in a room, and one of them is a foreign spy. Other three participants share a secret using the Shamir’s threshold scheme with secret in Zp, where p = 11. Any two of them can recover the secret. The foreign spy chooses his share randomly. As a result, these four participants have the following four shares: A : (1, 7), B : (3, 0), C : (5, 10), D : (7, 9)....

   Marathon petroleum distribution company manages 600 gas stations in Michigan. Each gas station typically has four underground storage tanks (UGST), three for gasoline and one for diesel. The UGST some times develop leaks due to corrosion or changes in soil conditions. Based on historical data, Marathon estimates that the probability that a given UGST develops a leak during a given year is 0.002 for gasoline storage tanks and higher at 0.003 for diesel storage tanks potentially due to higher density...
