Character encoding is used to represent a repertoire of characters by some kind of encoding system. Depending on the abstraction level and context, corresponding code points and the resulting code space may be regarded as bit patterns, octets, natural numbers, electrical pulses, etc

Encoding:
Encoding is the process of converting the data or a given sequence of characters,
symbols, alphabets etc., into a specified format, for the secured transmission of data
A process to translate the discrete set of sample values to more appropriate form.
Requirement:
For making the transmitted single more robust to noise, interference & other channel
impairments.

Why do computers use binary?
Binary is still the primary language for computers for the following reasons.
•It is a simple and elegant design.
•Binary's 0 and 1 method is quick to detect an electrical signal's off or on state.
•The positive and negative poles of magnetic media are quickly translated into binary.
•Binary is the most efficient way to control logic circuits.
What does Binary Code mean?
Binary code is the most simplistic form of data. It is represented entirely by a binary
system of digits consisting of a string of consecutive zeros and ones. Binary code is
often associated with machine code in that binary sets can be combined to form raw
code, which is interpreted by a computer or other piece of hardware.

Following is the list of advantages that binary code offers.
•Binary codes are suitable for the computer applications.
•Binary codes are suitable for the digital communications.
•Binary codes make the analysis and designing of digital circuits if we use the binary
codes.
•Since only 0 & 1 are being used, implementation becomes easy.
