description: The Data Encryption Standard (DES) is a symmetric-key block cipher that was widely used for encrypting data. It takes a fixed-size block of plaintext and transforms it into ciphertext using a secret key. Although DES has been superseded by more secure algorithms, it remains relevant in legacy systems.
explanation: DES is classified as an Encryption Algorithm because its primary function is to secure data transmission through encryption processes.  The text explicitly states its use for 'encrypting data' and describes its mechanism of transforming plaintext into ciphertext using a key.
