COMPUTER FUNDAMENTALS

Detailed explanation-1: -Ciphers, also called encryption algorithms, are systems for encrypting and decrypting data. A cipher converts the original message, called plaintext, into ciphertext using a key to determine how it is done.

Detailed explanation-2: -The formulas used to encode and decode messages are called encryption algorithms, or ciphers.

Detailed explanation-3: -What is a cipher? In cryptology, the discipline concerned with the study of cryptographic algorithms, a cipher is an algorithm for encrypting and decrypting data. Symmetric key encryption, also called secret key encryption, depends on the use of ciphers, which operate symmetrically.

Detailed explanation-4: -Algorithm has the same meaning in cryptography as elsewhere in computer science: a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer. This is the most general term on your list. A cipher is an algorithm you can use to encrypt or decrypt a message.

Detailed explanation-5: -Explanation: Cipher is an algorithm for performing encryption or decryption. In cryptography, a set of defined steps are followed to generate ciphers. These are necessary to prevent data breach.
