Chapter 16.4, Problem 2OE

To determine

To find: the point that can send the data the most points.

Answer to Problem 2OE

Points $B,C\text{ and }D$ .

Explanation of Solution

Given:

To point From point $\left[\begin{array}{cccc}\stackrel{A}{0}& \stackrel{B}{0}& \stackrel{C}{0}& \stackrel{D}{1}\\ 1& 0& 0& 1\\ 1& 1& 0& 0\\ 1& 0& 1& 0\end{array}\right]=Y.$

  $\left(a\right)\text{point }A\left(b\right)\text{point }B\left(c\right)\text{ point }C\left(d\right)\text{point D}\text{.}$

Concept used:

The points A, B, C and D in the diagram represent four ships at sea that are within communication range. The arrows indicate the direction of radio transmissions. For instances ship D can communicate directly.

Calculation:

Point $A$ can only send data $1$ point.

Points $B,C\text{ and }D$ can all send data to $2$ points. Therefore, point $B,C\text{ and }D$ can send data to the most points.

Hence, points $B,C\text{ and }D$ .
