Chapter 7 Accounting Information Systems QUESTIONS 1. The five fundamental principles of accounting information systems are: (a) control principle, (b) relevance principle, (c) compatibility principle, (d) flexibility principle, and (e) cost-benefit principle. 2. The five components of an accounting system are: source documents, input devices, information processors, information storage, and output devices. 3. Source documents contain data about business transactions or events that are put into the accounting system and processed. Examples of source documents are invoices from suppliers, checks received from customers, and payroll forms filled out by employees. 4. An input device is used to transfer data from source documents to the information processor(s). Examples of input devices for computer systems include keyboards, scanners, and bar-code readers. 5. Data stored "off-line" are not immediately available to the information processor(s), while "online" data are immediately available. 6. Output devices provide the means by which information is taken from the accounting system and made available for use. 7. Four types of transactions usually recorded in special journals are: (a) sales on credit, (b) purchases on credit, (c) cash receipts, and (d) cash disbursements. 8. The (a) initial and (b) page number of the journal from which the amount is posted is entered in the Posting Reference column of the ledger account. 9. The double posting does not cause the trial balance to be out of balance because only one credit is posted to the general ledger—the subsidiary ledger posting and its balances are not part of a trial balance (they give details of general ledger accounts). 10. When copies of the sales invoices are used as a sales journal, each invoice total is posted to the proper customer account in the subsidiary Accounts Receivable Ledger, after which the invoices are bound in numerical order. Then at the end of the period the bound invoice copies are totaled and the total is debited to Accounts Receivable and credited to Sales. This method is called direct posting of sales invoices .

11. Both kinds of credits must not be placed in the same column because the sum of the credits to the customer accounts must be posted to the Accounts Receivable controlling account (the Other Accounts column total is not posted—instead, each amount is individually posted to its general ledger account). Placing these credits in separate columns makes it possible to post the Accounts Receivable column total to its controlling account. 12. Immediate recording and posting of credit sales and cash receipts from customers provides up-to-date information for use in decisions about granting credit to customers. Also, up-to-date account balances are needed if customers inquire about their balances. 13.
