DES Modes - Electronic Code Book (ECB)
Traditionally,
each block of ciphertext is independent of other blocks
and is most frequently used for the coding of data on some storage medium
(such as a disk or transmitted via a network).
DES Modes - Cipher Block Chaining (CBC)
The notion of chaining ensures that each block
is dependent on earlier blocks:
Now, an intruder can neither insert nor delete any block without detection.
Cipher block chaining is hence typically used in networking applications.
