How many kilobytes will a 384-character 16-character alphabet message make?

Note: K is the number of characters in the message, I is the informational weight of the message, i is the informational weight of 1 character, N is the power of the alphabet. 1 byte = 8 bits, 1 KB = 1024 bytes.

Given:

K = 384 characters

N = 16 characters

Find: I.

Decision:

N = 2 ^ i;

16 = 2 ^ i;

i = 4 (bits) – informational weight of 1 character;

I = K * i = 384 * 4 = 1536 (bit) = 1536/8/1024 KB = 0.1875 KB.

Answer: 0.1875 KB.
