What is Coding and Decoding?

  • Coding is a process used to encrypt a word, a number in a particular code or pattern based on some set of rules. Hence Coding is the process of sending data from one person to another person in such a way that only the sender and receiver can understand the meaning without letting anyone else know the meaning of it. 
  • Decoding is a process to decrypt the pattern into its original form from the given codes.
  • Coding-Decoding is a system of signals to transmit the information in the form of signals or code without it being known to a  third party.

  • Coding decoding concepts can work in our real life. 

For example, if you notice that your kid can learn their letter sounds in kindergarten it means what sound to make when the letter is written on the board. The kid progresses to identify the constant vowel words, which helps to read loudly such as cat, dog, sun.

Kids will move to learn decoding words with consonant clusters, such as st, tr, cr, sk kids will learn to identify the words easily and kids is to phonics the words and phoneme to the words easily. 

Types of Coding and Decoding

1.Letter Coding
2.Number/Symbol Coding
3.Substitution Coding

Letter Coding

Letter coding-decoding in which the letter of words is replaced by certain other letters according to specific patterns/rules to form a code.
Example for Letter coding-decoding.
Detect the coding pattern /rule and answer the question below.
If BROWN is written as ‘ZPMUL’, then VIOLET is coded as     

  • TGMJCR
  • SGMJCQ
  • TGMJCQ
  • TGWCQ


Answer: In this question, the alphabet is replaced with another alphabet with some directions. The first letter B is coded as Z means that it moves backward with 1 letter similarly R is coded as P, O is coded as M,W is coded as U, and N is coded as L. So VIOLET is coded as TGMJCR.

Number/Symbol coding

Number coding-decoding in which either the numerical code values are assigned to a word or alphabetical code letters are assigned to the numbers.
Example for Number/Symbol coding-decoding.
If CHAIR is written as ‘12345’, RENT is written as ‘5678’,    and then     REAR is written as.

  • 5635
  • 5356
  • 5365
  • 5653

Answer:

In this question each alphabet is coded as a number. So that CHAIR is coded as 12345 and RENT is coded as 5678 and the REAR is coded as 5635.

Substitution coding

Substitution coding-decoding in which some particular words are assigned with certain substituted names.
Example for Substitution coding-decoding.
If a dog is called “cat”, cat is called “lion”, lion is called “rat”, then which of these lives in a forest?

  • Rat
  • Lion
  • Dog
  • Cat

Answer: In this question, lion lives in the forest but lion is called a rat so rat lives in a forest is the answer.

What is coding and decoding?

What are the different types? 

Reading is the key skill for the learning process of, ability to letter-sound relationships to pronounce the written words. In reality, the children will usually express their frustration and difficulties in a general way, with statements like “I hate reading”.  Coding-Decoding is essential to reading, it allows kids to figure out most words and Coding-Decoding is the foundation of reading instructions like fluency, vocabulary, reading comprehension, phonics, and phonemic to words.

Coding-Decoding helps the children to give knowledge of letter-sound relationships, and successfully recognize familiar words quickly and figure out words.

Coding-Decoding

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. Coding is, therefore, a method of transmitting a message between sender and receiver which cannot be understood or comprehended by a third person. The Coding and Decoding test is mainly to judge the test-taker’s ability to decipher a particular word/message by breaking the code or decoding the same.

Miscellaneous examples for coding-decoding

Question 1: If the desk is called “chair”, chair is called “blackboard”, blackboard is called “duster”, duster is called “chalk”, and then where do you sit in the classroom?

  • Blackboard
  • Chair
  • Desk
  • Duster

Answer: In this question, we clearly know that in the classroom we sit on a  chair.And as the chair is called a blackboard, the answer is blackboard.

Question 2: If cake is called “egg”, if egg is called “coffee”, coffee is called “tea”, then which is white in colour?

  • Cake
  • Egg
  • Coffee
  • Tea

Answer: Egg is of white colour.But egg is called coffee so coffee is the answer.
