Detailed explanation-1: -Monoalphabetic cipher is a substitution cipher in which for a given key, the cipher alphabet for each plain alphabet is fixed throughout the encryption process. For example, if ‘A’ is encrypted as ‘D’, for any number of occurrence in that plaintext, ‘A’ will always get encrypted to ‘D’.
Detailed explanation-2: -All that being said, while codes and ciphers are different, the terms are often used interchangeably. Morse code, for example, it technically a cipher, not a code. Nonetheless it is called Morse code, not Morse cipher.
Detailed explanation-3: -There are many different monoalphabetic substitution ciphers, in fact infinitely many, as each letter can be encrypted to any symbol, not just another letter.
Detailed explanation-4: -This is kind of related to Morse code, but only in a way. By itself, Morse is a substitution cipher, where “.” replaces “e”, “-” replaces “t”, “–” is “o”, “…” is “s”, and so on.
