Key Points to Remember:
A CODE is a system of signals.
Coding is a method of transmitting a message between the sender and the receiver without the third person knowing it.
Coding and Decoding test is ability to decipher the rule that codes a particular word or message and break the code to decipher the message.
The various types of Coding and Decoding are,
Type 1 : Letter Coding
Type 2: Direct Letter Coding
Type 3 : Number / Symbol Coding
Type 4 : Matrix Coding
Type 5 : Substitution
Type 6 : Deciphering Message Word Codes
Type 7 : Deciphering Number and Symbol Codes for messages
Let's see exercises for Type 1 Coding and Decoding.

If in a certain code, LUTE is written as MUTE and FATE is written as GATE, then how will BLUE be written in that code?
Answer is CLUE
Answer is CLUE
The first letter of the word is moved one step forward to obtain the first letter of the code, while the other letters remain unaltered.
Question 2:
In a certain code, MADRAS is coded as NBESBT, how is RANCHI coded in that language?
Answer is SBODIJ
Answer is SBODIJ
Each letter in the word s moved one step forward to obtain the corresponding letter of the code.
Question 3:
In a certain code language, OPERATION is written as NODQBUJPO. How is INVISIBLE written in that code?
Answer is HMUHTJCMF
Each of the four letters in the word is moved one step backward, while each of the last five letters is moved one step forward to obtain the corresponding letter of the code.
