Coding/Decoding Practice Exercises
A code is “a system of signals”. Coding is, therefore, a method of transmitting a message between the sender and the receiver which third person cannot understand or comprehend. The coded message can be deciphered or decoded by the receiver as he or she knows the rule or method which are employed in encoding the message. Thus, the CODING-DECODING test is given to judge the candidates ability to decipher the rule which is applied for coding a particular message and break the code to reveal the message. In this type of questions some words or a group of letters and their coded forms are provided and you are required to find out the rule of coding so that you can either encode or decode another word or another group of letters in similar fashion. Any word or message or a group of letters can be coded in a variety of ways. Generally, each question is based on a particular rule of coding. Therefore, clues of a particular question are not applicable to the other questions.
We have already mentioned that several types of questions can be asked on CODING-DECODING. Each type of questions has its own coding patterns. The coding patterns may be based on individual alphabet/words and digits/numbers. The code of a particular letter could be following or preceding letter, the letters of a meaningful word can be jumbled to generate code and so on. In order to have a clear insight into the questions on coding-decoding, it is better to discuss each type of questions separately.
Type – 1:
Code based on English alphabets
Type – 2:
Code consisting of a group of words
Type – 3:
Code consisting of digits or vice-versa
Type – 4:
Code consisting of symbols
