Frequently Asked Questions
How do you calculate the binary code of a text character?
To calculate binary from a letter: find the letter's decimal ASCII value (e.g. 'C' = 67), then convert that number to base-2 by dividing by 2 successively: 67 = 64 + 2 + 1 = 01000011 in 8-bit binary.
What is the binary representation of uppercase vs lowercase letters?
In ASCII, uppercase and lowercase letters differ by exactly one bit (the 6th bit, value 32). For example, uppercase 'A' is 01000001 (decimal 65) and lowercase 'a' is 01100001 (decimal 97).
What is the binary code for a space character?
The standard ASCII space character has a decimal value of 32, which is 00100000 in 8-bit binary.
