Q.Define accounting and explain the four functions covered by the AICPA definition.

Accounting is usually explained through the AICPA definition, which packs four separate steps into one sentence.

The American Institute of Certified Public Accountants (AICPA) defines accounting as "the art of recording, classifying and summarising in a significant manner and in terms of money, transactions and events which are, in part at least, of a financial character, and interpreting the results thereof."

This definition covers four distinct steps:

1. Recording — every transaction of a financial nature is entered, date-wise, in the Journal, the book of original/prime entry.
2. Classifying — the recorded transactions are grouped by nature into separate accounts in the Ledger (e.g. all transactions with a debtor collected under that debtor's account).
3. Summarising — the classified data is presented in a form useful to readers — the Trial Balance, Trading and Profit & Loss Account, and Balance Sheet.
4. Interpreting — the summarised results are analysed (e.g. through ratios and trends) to draw conclusions about the profitability and financial soundness of the business, so users can take informed decisions.

The phrase "in terms of money" is key — only events measurable in money enter the accounting process at all.

Students often stop at 'recording and classifying' and forget that summarising and interpreting are equally part of the definition — a common exam slip is describing only book-keeping (recording + classifying) and calling it 'accounting'.
