Encoding and Decoding :

In computers, encoding is the process of putting a sequence of characters (letters, numbers, accentuation, and certain symbols) into a particular organization for efficient transmission or storage. Decoding is the contrary process - the transformation of an encoded design again into the original sequence of characters. Encoding and decoding are utilized in data communications, networking, and storage. The term is especially pertinent to radio (wireless) communications frameworks.


The code utilized by most PCs for text files is known as ASCII (American Standard Code for Information Interchange, pronounced ASK-ee). ASCII can delineate uppercase and lowercase alphabetic characters, numerals, accentuation marks, and normal images. Other commonly-used codes include Unicode, BinHex, Uuencode, and MIME. In information communications, Manchester encoding is a special form of encoding in which the binary digits (bits) speak to the changes amongst high and low logic states. In radio communications, various encoding and decoding methods exist, some of which are used just by specialized groups of people (amateur radio operators, for instance). The most established code of all, initially employed in the landline telegraph amid the 19 th century, is the Morse code.

The terms encoding and decoding are regularly utilized in reference to the procedures of analog-to-digital conversion and digital-to-analog conversion. In this sense, these terms can apply to any type of data, including content, pictures, sound, video, sight and sound, PC programs, or signals in sensors, telemetry, and control systems. Encoding ought not be mistaken for encryption, a procedure in which data is deliberately altered in order to cover its content. Encryption should be possible without changing the specific code that the content is in, and encoding should be possible without deliberately hiding the content .
