CODING-DECODING is an important part of the Logical reasoning section in all aptitude-related examinations. Coding is a process used to encrypt a word, a number in a particular code or pattern based on some set of rules. Decoding is a process to decrypt the pattern into its original form from the given codes. Letter Coding In this type of question, the alphabets of a word are replaced by some other alphabets according to specific rules to form code. Number Coding In this type of question, a word is replaced by certain numbers according to some specific rule. Coding is a method of transmitting a message between the sender and the receiver without a third person knowing it. Before transmitting, the data is encoded and at the receiver’s side, the data is decoded in order to obtain original data by determining common keys in encoded data. Coding and Decoding forms a dedicated part of the Reasoning Section in various competitive exams but the level of questions differs in them. For example in SSC, the level of questions is easy to medium while in IBPS exams, the level of questions is difficult. In IBPS, coding and decoding questions come under Machine Coding and Decoding Topic.
How to solve coding and decoding? Observe alphabets or numbers given in the code keenly. Find the sequence it follows whether it is ascending or descending. Detect the rule in which the alphabets/numbers/words follow. Fill the appropriate letter/number/word in the blank given. Decoding is the process of reading words in a text. When a child reads the words ‘The ball is big,’ for example, it is necessary to understand what the letters are, the sounds made by each letter, and how they blend together to create words. Encoding is the process of using letter/sound knowledge to write.
