WebLook at the 12-hour clock in your room. You see 12 numbers on the clock. Here, the modulus is 12 with the twelve remainders 0,1,2,..11. So, when you give the time you actually give a remainder between 0 and 11. Again, the modulus m=12 is in charge of these reminders. What time is it 50 hours after midnight?

WebIn cryptography, a cipher (or cypher) is a method for protecting data through encryption and decryption. Most ciphers require a specific key for encryption and decryption, but some ciphers like the ROT13 or Atbash ciphers have fixed keys.
