I. Choose the Best Answer (MCQs)

Q1. The most popular accounting software in India is (a) QuickBooks (b) Tally (c) SAP (d) Zoho Books

Answer(b) Tally — Tally (now Tally Prime) is the most widely used accounting software in India, especially for small and medium businesses.

Q2. In computerised accounting, journal entries are automatically posted to (a) Trial balance only (b) Ledger accounts (c) Balance sheet only (d) Cash book only

Answer(b) Ledger accounts — In computerised accounting, when a transaction is entered, the software automatically posts it to the relevant ledger accounts, eliminating manual posting errors.

Q3. Which of the following is an advantage of computerised accounting? (a) High initial cost (b) Dependency on electricity (c) Speed and accuracy (d) Training required

Answer(c) Speed and accuracy — Speed and accuracy are the primary advantages of computerised accounting. High initial cost, power dependency, and training required are limitations.

Q4. GIGO stands for (a) Good Input Good Output (b) Garbage In Garbage Out (c) General Input General Output (d) Graphical Input Graphical Output

Answer(b) Garbage In Garbage Out — GIGO means that if wrong data is entered into the computer, the output will also be wrong. The computer processes whatever is input; it cannot judge the correctness of data.

Q5. Which module of accounting software processes employee salaries? (a) General Ledger (b) Accounts Payable (c) Payroll (d) Inventory

Answer(c) Payroll — The Payroll module handles salary processing, including basic pay, deductions (PF, ESI, TDS), net pay calculation, and payslip generation.

II. Fill in the Blanks

1. Computerised accounting uses accounting software to record and process financial transactions. 2. The most popular accounting software in India is Tally (Tally Prime). 3. In computerised accounting, posting to ledger accounts is done automatically. 4. The trial balance in computerised accounting is always balanced. 5. GIGO stands for Garbage In Garbage Out. 6. The payroll module processes employee salaries. 7. The inventory module tracks stock levels and valuation. 8. The main limitation of computerised accounting is high initial cost and dependency on technology. 9. In manual accounting, the trial balance may not balance due to arithmetic errors. 10. Password protection and audit trail are security features of computerised accounting.

III. True or False (with corrections for false statements)

Q1. Computerised accounting eliminates all types of errors.

AnswerFalse — Correction: Computerised accounting eliminates ARITHMETIC errors, but not logical errors. If wrong data is entered (GIGO), the output will also be wrong.

Q2. In computerised accounting, the trial balance is always balanced.

AnswerTrue — In computerised accounting, the trial balance is automatically generated from the ledger accounts and is always balanced because of the double-entry system built into the software.

Q3. Manual accounting is faster than computerised accounting.

AnswerFalse — Correction: Computerised accounting is much FASTER than manual accounting. Reports are generated instantly, and posting is automatic.

Q4. Audit trail is a feature of computerised accounting.

AnswerTrue — An audit trail records who made each entry, when, and any changes made. This feature helps in tracking and verifying transactions.

Q5. Computerised accounting does not require any accounting knowledge.

AnswerFalse — Correction: Computerised accounting requires accounting knowledge to understand what to enter, how to classify transactions, and how to interpret reports. The software only automates the mechanical tasks.

Q4. What are the main modules of accounting software?

Answer

1. General Ledger: Records all financial transactions 2. Accounts Payable: Manages creditor accounts and payments 3. Accounts Receivable: Manages debtor accounts and receipts 4. Payroll: Processes salaries and deductions 5. Inventory: Tracks stock levels and valuation 6. Reporting: Generates financial statements and analysis reports

VI. Answer in Detail (5-mark questions)

Q1. Explain the advantages of computerised accounting over manual accounting.

Answer

1. Speed and Efficiency: Transactions are processed instantly. Reports like trial balance, P&L, and balance sheet are generated in seconds. What takes hours manually can be done in minutes. 2. Accuracy: Automatic calculations eliminate arithmetic errors. The software ensures that debits equal credits for every transaction, so the trial balance is always balanced. 3. Automatic Posting: When a transaction is entered, the software automatically posts it to all relevant ledger accounts. This eliminates manual posting errors. 4. Instant Reports: Financial statements, trial balance, ledgers, and other reports can be generated at the click of a button. Customised reports can be created for specific needs. 5. Data Storage and Retrieval: Large volumes of data can be stored digitally in a compact form. Any transaction can be found instantly using search functions. 6. Multi-user Access: Multiple users can work on the same data simultaneously from different locations (in cloud-based software). 7. Security: Password protection, user-level access control, and audit trail ensure data security. Every entry is tracked — who made it, when, and any changes. 8. GST Compliance: Accounting software automatically calculates GST, generates GST reports, and helps in filing returns. 9. Automatic Bank Reconciliation: Bank transactions can be imported and reconciled automatically. 10. Backup and Recovery: Data can be backed up automatically and recovered in case of system failure.

Q2. Explain the limitations of computerised accounting.

Answer

1. High Initial Cost: Setting up a computerised accounting system requires investment in hardware, software, and infrastructure. This can be expensive for small businesses. 2. Training Required: Staff need to be trained to use the accounting software. Without proper training, errors can occur. 3. Power Dependency: Computerised accounting cannot work without electricity. Power failures can disrupt work and cause data loss if not saved. 4. System Failure: Computer crashes, viruses, and hardware failures can lead to data loss. Regular backups are essential. 5. Security Risks: Data can be hacked, stolen, or manipulated by unauthorised persons. Strong password policies and security measures are needed. 6. GIGO (Garbage In, Garbage Out): If wrong data is entered, the output will also be wrong. The computer cannot detect logical errors — it only processes what is input. 7. Reduced Human Judgement: The software cannot handle unusual or complex transactions without human intervention. It follows rules rigidly. 8. Obsolescence: Software needs regular updates. New versions may not be compatible with old data. Annual subscription or update costs apply. 9. Dependency on Vendor: The business becomes dependent on the software vendor for updates, support, and troubleshooting. 10. Loss of Manual Skills: Over-reliance on computers can lead to a decline in manual accounting skills, making it difficult to work without the software.

Common Mistakes to Avoid

Saying computerised accounting eliminates ALL errors: It only eliminates arithmetic errors. Logical errors (wrong classification, wrong data entry) still occur (GIGO).
Confusing modules: General Ledger = recording transactions; Payroll = salary processing; Inventory = stock management. Don't mix them up.
Forgetting limitations in comparison: When comparing manual vs computerised, don't only list advantages. Always mention limitations too (cost, training, power dependency).
Not understanding GIGO: GIGO means that the computer processes whatever data is given. If the input is wrong, all reports will be wrong. Human verification is still essential.
Saying "computerised accounting doesn't need accounting knowledge": You still need to understand debits, credits, classification, and financial statements. The software automates the mechanical tasks, not the thinking.
