Answer:

Sir William Crookes invented the cathode ray tube in 1878, but these discoveries took many years to merge into the common ground of television. ... His mechanical system used a scanning disk with small holes to pick up image fragments and imprint them on a light-sensitive selenium tube. A receiver reassembled the picture.

<em>Television is really a three-part invention: the TV camera that turns a picture and sound into a signal; the TV transmitter that sends the signal through the air; and the TV receiver (the TV set in your home) that captures the signal and turns it back into picture and sound. </em>

In the program below, what is the scope of strFirst?
MAXImum [283]

First, we have to understand what scope is. When variables are declared, they are only available in the code block they're declared in, unless they're global variables (this doesn't apply here).

strFirst is declared in usernameMaker and that is the only place it is available in.
