True.
Explanation:
Wide area network (WAN) can be defined as a telecommunication network that covers a wide range of geographical locations such as countries or regions across the world for the purpose of communication and sharing information and data between different users.
Hence, a network that has locations in different countries is considered a wide area network (WAN).
Generally, wide area network (WAN) makes it possible for various organizations to interconnect with their branch offices, headquarters and other multiple locations across the globe. Wide area network (WAN) usually span over a distance of 50 kilometers.

Showing all formulas in all cells
To show formulas in all cells press CTRL+` (that little mark is the grave accent mark key). When the formulas are visible, print your worksheet as you normally would. To switch back to showing formula results in all cells, press CTRL+` again.
1.)
<span>((i <= n) && (a[i] == 0)) || (((i >= n) && (a[i-1] == 0))) </span>
<span>The expression will be true IF the first part is true, or if the first part is false and the second part is true. This is because || uses "short circuit" evaluation. If the first term is true, then the second term is *never even evaluated*. </span>
<span>For || the expression is true if *either* part is true, and for && the expression is true only if *both* parts are true. </span>
<span>a.) (i <= n) || (i >= n) </span>
<span>This means that either, or both, of these terms is true. This isn't sufficient to make the original term true. </span>
<span>b.) (a[i] == 0) && (a[i-1] == 0) </span>
<span>This means that both of these terms are true. We substitute. </span>
<span>((i <= n) && true) || (((i >= n) && true)) </span>
<span>Remember that && is true only if both parts are true. So if you have x && true, then the truth depends entirely on x. Thus x && true is the same as just x. The above predicate reduces to: </span>
<span>(i <= n) || (i >= n) </span>
<span>This is clearly always true. </span>
