Encapsulation
(1) In programming, the process of combining elements to create a new entity. For example, a procedure is a type of encapsulation because it combines a series of computer instructions. Likewise, a complex data type, such as a record or class, relies on encapsulation. Object-oriented programming languages rely heavily on encapsulation to create high-level objects. Encapsulation is closely related to abstraction and information hiding.
(2) In networking, same as tunneling.

- encode
The phrase used to describe the method of preparing data for storage or transmission. Encoding data usually means redundancies are eliminated and complexity in the data is reduced. Compression algorithms are also based on one or more encoding methods.
- encoder

- Encoding
(1) In computer technology, encoding is the process of putting a sequence of characters into a special format for transmission or storage purposes. (2) The term used to reference to the processes of analog-to-digital conversion, and can be used in the context of any type of data such as text, images, audio, video or multimedia.
- Encryption
The translation of data into a secret code. Encryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Unencrypted data is called plain text ; encrypted data is referred to as cipher text. There […]
- encryption algorithm
A mathematical procedure for performing encryption on data. Through the use of an algorithm, information is made into meaningless cipher text and requires the use of a key to transform the data back into its original form. Blowfish, AES RC4, RC5, and RC6 are examples of encryption algorithms.
