Answer: False
Explanation:
Unguided medium employs an antenna for transmitting through air or vacuum.
For guided mediums the transmission is in the form of twisted copper wires, shielded twisted copper wire and optical fibres. They henceforth do not depend upon antennas for transmission through air using antennas.
That would be Open DataBase Connectivity (ODBC).

Answer:
Written in Python:
num1 = 10
num2 = 15
print(num1)
print(num2)
print(num1 * num2)
Explanation:
The programs requires that two number be assumed and multiplied.
The program uses num1 and num2 to represent the two numbers (line 1 and line2)
These numbers were then initialized to 10 and 15, respectively (note that, you can replace these numbers with any number of your choice)
The next two lines then print num1 and num2
The last line prints the result of their multiplication
However, line by line explanation is as follows:
<em>This line initializes num1 to 10</em>
num1 = 10
<em>This line initializes num2 to 15</em>
num2 = 15
<em>This line prints num1</em>
print(num1)
<em>This line prints num2</em>
print(num2)
<em>This line prints the product of num1 and num2</em>
print(num1 * num2)
