Question

19. Which of the following characteristics distinguishes computer processing from manual processing? A. Computer processing virtually eliminates the occurrence of computational error normally associated with manual processing. B. Errors or fraud in computer processing will be detected soon after their occurrence. C. The potential for systematic error is ordinarily greater in manual processing than in computerized processing. D. Most computer systems are designed so that transaction trails useful for audit purposes do not exist. 20. An entity has the following invoices in a batch: Invoice Number Product Quantity Unit Price 201 F10 150 $ 5.00 202 G15 200 10.00 203 H20 250 25.00 204 K35 300 30.00 Which of the following most likely represents a hash total? A. FGHK80 B. 4 C. 204 D. 810

Answer 1

1. Answer (a) is correct because the high degree of accuracy of computer in computation virtually eliminates the occurrence of computational errors.

2. Answer (D) is correct because hash control is used to verify the completeness of the inputted data. Hash total can be employee numbers, or invoice numbers. Thus, the hash total of invoice numbers is 810 (201 + 202 + 203 + 204).
