Step 1: Understand the question:
The question asks for two things: the meaning of codification, and the meaning of mnemonic codes with an example.
The answer is worth 3 marks, so we give three points: the meaning of code, the meaning of mnemonic codes and one example.
Step 2: Meaning of codification:
The term code means a system of letters or figures with arbitrary meaning, used for brevity and for machine processing of information.
So a code is an identification mark.
Codification is the process of giving such codes to items, accounts or transactions so that a computer can handle them quickly.
Step 3: Meaning of mnemonic codes:
Mnemonic codes consist of alphabets or abbreviations used as symbols to codify a piece of information.
They are easy to remember because the letters hint at the item.
Step 4: Give the example:
The letters SJ are used for the Sales Journal in accountancy.
A user needs a reference list to understand these codes, because the letters alone do not state the full meaning.
Final Answer:
Codification is giving codes, which are systems of letters or figures with arbitrary meaning used for brevity and machine processing.
Mnemonic codes use alphabets or abbreviations as symbols, for example SJ for the Sales Journal.
