**COMPUTERISED ACCOUNTING SYSTEM — QUICK REFERENCE**
**Definition:** Processing accounting transactions via hardware and software to produce financial records and reports (journals, ledgers, trial balance, Balance Sheet, P&L).
**Five Pillars of CAS:**
1. Procedure — logical sequence of actions
2. Data — raw input facts (date, amount, account name, code)
3. People — users and operators
4. Hardware — computers, peripherals, networks
5. Software — system and application software
**Data vs Information:**
• Data = smallest named unit (e.g. days worked = 5, rate = ₹100)
• Information = processed data answering decision need (e.g. amount to pay = ₹500)
**Accounting Cycle (still applies in CAS):**
Analyse → Record in Journal → Post to Ledger → Trial Balance → Adjustments → Adjusted Trial Balance → Financial Statements
**Accounting Equation (Foundation of CAS):**
Assets = Liabilities + Capital + (Revenues − Expenses)
OR A = L + C (before P&L adjustment)
**Salient CAS Features:**
• Simple & Integrated — automates all operations (sales, purchase, finance, inventory)
• Transparency & Control — day-to-day visibility and vital information access
• Accuracy & Speed — user templates, fast data entry, minimal errors
• Scalability — adjusts to business growth without system change
• Reliability — ensures critical financial data is accurate, controlled, secured
**Account Classification (Schedule III format):**
**EQUITY & LIABILITIES:**
• Shareholder's Funds: Share Capital, Reserves & Surplus, Share Application Money
• Non-Current Liabilities: Long-term Borrowings, Deferred Tax, Long-term Provisions
• Current Liabilities: Short-term Borrowings, Trade Payables, Current Provisions
**ASSETS:**
• Non-Current: Fixed Assets (Tangible, Intangible), Investments, Deferred Tax Assets, Long-term Loans
• Current: Inventories, Trade Receivables, Cash, Short-term Investments, Prepaid Expenses
**Key Principle:** CAS automates the accounting cycle but does NOT change GAAP or double-entry principles—it just speeds up, secures, and integrates the process.
Q1. Computerised Accounting System (CAS) refers to which of the following?
Answer: A — CAS is specifically the automated processing of transactions through hardware and software to generate journals, ledgers, trial balance, and financial statements, while maintaining GAAP principles.
Q2. Which of the following is NOT one of the five pillars of Computerised Accounting System?
Answer: C — The five pillars are Procedure, Data, People, Hardware, and Software; 'Report' is an output, not a foundational pillar of CAS.
Q3. In the context of CAS, what is the main difference between 'data' and 'information'?
Answer: B — Data is raw input (e.g. days worked, rate per day); information is when that data is processed to answer a business question (e.g. wages payable).
Q4. Which of the following is an example of a 'data element' in an accounting transaction according to CAS concept?
Answer: B — A transaction in CAS consists of four data elements: account name, accounting code, transaction date, and amount—these are the smallest named units of data.
Q5. The accounting equation that forms the foundation of CAS is?
Answer: B — The extended accounting equation includes the income statement impact (Revenues − Expenses) to show how profit changes capital, and this is the basis for classifying accounts in CAS.
Q6. Which salient feature of CAS allows the software to handle both small and large business transaction volumes without requiring system changes?
Answer: C — Scalability specifically refers to CAS's ability to change data processing volume in tune with business growth without major system modifications.
Q7. Which of the following steps in the accounting cycle comes IMMEDIATELY after posting journal entries to the ledger?
Answer: B — The sequence is: Journal → Ledger → Trial Balance → Adjustments → Adjusted Trial Balance → Financial Statements.
Q8. According to the accounting equation A = L + C, if a business has Assets of ₹5,00,000 and Liabilities of ₹2,00,000, what is the Capital?
Answer: B — Capital = Assets − Liabilities = ₹5,00,000 − ₹2,00,000 = ₹3,00,000.
Q9. Which of the following pairs correctly represents the classification of an account under 'Current Liabilities' in CAS?
Answer: B — Current Liabilities include Short-term Borrowings, Trade Payables, Other Current Liabilities, and Short-term Provisions; Long-term items belong to Non-Current Liabilities.
Q10. Which statement is CORRECT regarding the relationship between CAS and Generally Accepted Accounting Principles (GAAP)?
Answer: B — CAS is a tool that speeds up and automates the accounting cycle, but it does not change the fundamental requirement that financial statements comply with GAAP.
What is a Computerised Accounting System (CAS)?
CAS is the processing of accounting transactions through hardware and software to produce accounting records and reports following GAAP principles.
Name the five pillars on which CAS rests.
Procedure, Data, People, Hardware, and Software are the five core components of a Computerised Accounting System.
What is the difference between data and information in accounting?
Data is raw facts (e.g. days worked, rate per day); information is processed data that answers a specific decision-making question (e.g. amount to pay).
Define the accounting equation used in CAS.
Assets = Liabilities + Capital + (Revenues − Expenses), where all components must balance under double-entry system.
What are the main phases of the accounting cycle in CAS?
Analyse transactions, record in journal, post to ledger, prepare trial balance, make adjustments, prepare adjusted trial balance, then generate financial statements.
What is meant by 'Scalability' in CAS?
Scalability means CAS can adjust its data processing volume to match changes in business size and transaction volume without requiring system overhaul.
Name three salient features of CAS software.
CAS must be Simple and Integrated, provide Transparency and Control, ensure Accuracy and Speed, be Scalable, and maintain Reliability of financial data.
How does CAS ensure accuracy in financial reporting?
CAS uses user-definable templates for fast and accurate data entry, automated processing, and validation rules to minimize manual errors and ensure control.
What is the purpose of grouping accounts in CAS?
Grouping accounts into Assets, Liabilities, and Equity classifications helps organise large volumes of transaction data according to the accounting equation and GAAP.
Which accounts fall under 'Current Liabilities' in CAS classification?
Current Liabilities include Short Term Borrowings, Trade Payables, Other Current Liabilities, and Short Term Provisions.
Define 'Computerised Accounting System' and state any two advantages of using CAS in modern business. [2 marks]
Define CAS as processing transactions via hardware/software; mention advantages like speed, accuracy, real-time access, reduced errors, or better decision-making.
Explain the five pillars of Computerised Accounting System with a brief example of each. How do these pillars work together to ensure effective financial accounting? [5 marks]
Describe each pillar (Procedure, Data, People, Hardware, Software) with one short example; then explain integration—e.g. software processes data (entered by people) following procedures using hardware to generate reports. Show how all five are interdependent.
The accounting equation is the foundation of CAS. Starting with the basic equation A = L + C, derive the extended equation that incorporates revenues and expenses, and explain how this extended equation helps in classifying accounts in a Computerised Accounting System according to Schedule III format. [6 marks]
Start with A = L + C; explain that capital changes due to profit/loss, so extend to A = L + C + (R − E); show how each component (Assets, Liabilities, Equity, Revenue, Expense) is classified into sub-groups (Non-Current/Current, Fixed/Current Assets, Shareholder Funds/Borrowings) in CAS, making data entry and report generation systematic and GAAP-compliant.
