What is coding decoding

Dear Student

The process of representing information in a definite standard form is called coding and the inverse process of recovering the information in terms of such a representation of it is called decoding.
You will generally use  it in Reasoning.
An encoding (coding) is a mapping of an arbitrary set AA into the set of finite sequences (words) over some alphabet BB, while the inverse mapping is called a decoding.
Example-   In certain language A,B,C and all alphabets can coded as 1,2,3 etc. and you can use this coding in writing different words or even your name and many other things.
