The correct option is D 12.5
If 7 bits are used to
store a character, the percentage reduction of needed storage will be 12.5.
A byte is a unit of
data that is eight binary digits long. A byte is the unit most
computers use to represent a character such as
a letter, number.
An ASCII character in 8-bit, ASCII encoding is 8 bits (1
byte), though it can fit in 7 bits. The original ASCII table is encoded on 7 bits therefore it has 128.
