What type of coding uses abbreviations or letters to represent specific information like "SJ" for Sales Journal?

(A) Sequential Code

(B) Block Code

(C) Mnemonic Code

(D) Numerical Code

Choose the correct answer from the options given below:

Mnemonic Code is a coding system that uses abbreviations, letters, or combinations of letters that are easy to remember and directly relate to the information they represent.

In the given example, "SJ" stands for Sales Journal - the letters are derived from the first letters of the words, making it easy to recall and associate with the actual journal.

Other types of codes work differently:

• Sequential Code assigns numbers in order (1, 2, 3...)
• Block Code reserves number ranges for categories (100-199 for one group, 200-299 for another)
• Numerical Code uses only numbers

Since "SJ" uses letters as abbreviations to represent information in a memorable way, it is specifically a Mnemonic Code.
