Answer:
D. infrared.
Explanation:
Wireless technology for communication uses electromagnetic wave to transmit signals between location. It eliminates the need of cables for connecting network devices.
In previous wireless technology implementation, Infrared rays were used (in tv remotes), which needed to be in the line of sight to its destination. Although it was fast, it has many limitations for a long-haul transmission like its short transmission range, easily blocked by objects and its uni-directional properties.

Answer: A keyframe is a location on a timeline which marks the beginning or end of a transition. So for example, you have a movie and it transitions to another scene, keyframes tell it when and where to start the transition then when and where to stop the transition.
Reasons why the height of a VHF radio antenna is important is because VHF radios work by the line of sight principle.
Line of sight its a line from observers eye to a distant point.its a line between two points specifically the straight path between a transmitting antenna (as for radio or television signals) and receiving antenna when unobstructed by the horizon.
Complete Question:
Assume that an array of Integers named a that contains exactly five elements has been declared and initialized. In addition, an int variable j has also been declared and initialized to a value somewhere between 0 and 3.
Write a single statement that assigns a new value to the element of the array indexed by j. This new value should be equal to twice the value stored in the next element of the array (i.e. the element after the element indexed by j ). Do not modify any other elements of the array!
Answer:
a[j] = 2 * a[j+1];
Explanation:
Since the array is named a and its indexes are referenced by the variable j
it means the elements of the array will be a[j] for (j=0; j=1;j=2).
The first element in the array (j=0) will be a[0], second element will be a[1] and so on.
The statement a[j] = 2 * a[j+1]; assigns a new value to the element of the array indexed by j, the value is equal to twice the value stored in the next element of the array (j+1).
