Chapter 16.4, Problem 1OE

To determine

To find: the name of the destination to which point can send the data.

Answer to Problem 1OE

  $\left(a\right)D;\left(b\right)A,D;\left(c\right)A,B;\left(d\right)A,C.$

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:

If there is a $1$ , that means a point can transfer data to another specific point.

  $a:$ point $A$ can send data to point $D$ .

  $b:$ point $B$ can send data to points $A$ and $D$ .

  $c:$ point $C$ can send data to points $A$ and $B$ .

  $d:$ Point $D$ can send data to point $A$ and $C$ .

Hence, $\left(a\right)D;\left(b\right)A,D;\left(c\right)A,B;\left(d\right)A,C.$
