How many bytes per character in ASCII system?
A
0.5
B
1
C
1.5
D
10
Explanation: 

Detailed explanation-1: -Each character is encoded as 1 to 4 bytes. The first 128 Unicode code points are encoded as 1 byte in UTF-8. These code points are the same as those in ASCII CCSID 367.

Detailed explanation-2: -Digit characters have code values that differ from their numeric equivalents: the code value of ‘0’ is 48, that of ‘1’ is 49, that of ‘2’ is 50, and so forth.

Detailed explanation-3: -We call 8 bits a byte. The very common ASCII system makes each letter of the alphabet, both capital and small (plus punctuation and some other symbols) correspond to a number from 0 to 255 (for example a=97, b= 98 and so on), so one letter can be expressed with one byte.
