The message size is 11 Kbytes. The message contains 11,264 characters. What is the cardinality of the alphabet with which the message is written?

Given:
I = 11 KB
K = 11264 = 11 * 2 ^ 13
Find: N -?
Decision :
find out how many bits are allocated for 1 character. for this we translate the message volume into bits
11 KB = 11 * 2 ^ 13 and divided by the number of characters
1 character is 11 * 2 ^ 13/11 * 2 ^ 13 = 2 ^ = 8 bits
power of the alphabet = 2 ^ 8 = 256 characters
Answer: 256 characters
