1. Which of the following best describes the primary purpose of an Accounting Information System (AIS)? A) To automate all management decision-making processes B) To collect, process, store, and report financial information for decision-making C) To eliminate all business risks and threats D) To manage human resource operations exclusively Answer: B Rationale: An Accounting Information System (AIS) integrates people, processes, data, and technology to collect, process, store, and communicate financial and accounting information. The system supports operational activities, management decision-making, regulatory compliance, and financial reporting. It does not replace management functions nor eliminate all business risks . ________________________________________ 2. What are the six components of an Accounting Information System (AIS)? A) Hardware, software, networks, databases, procedures, and reports B) People, procedures and instructions, data, software, IT infrastructure, and internal controls C) Input, processing, output, storage, control, and feedback D) Journals, ledgers, worksheets, financial statements, controls, and audits Answer: B Rationale: The six components of an AIS are People (users), procedures and instructions, data, software, information technology infrastructure, and internal controls and security measures. An AIS is more than just software—it encompasses the people who use it, the procedures that guide its use, the data it processes, the technology that supports it, and the controls that protect it . ________________________________________ 3. What is the difference between data and information? A) Data is always numerical while information is always textual B) Data are raw facts about events and transactions; information is data that has been organized and processed to provide meaning and improve decision-making C) Data is processed while information is unprocessed D) There is no meaningful difference between the two terms Answer: B Rationale: Data are raw facts about events and transactions. Information is data that has been organized and processed to provide meaning and improve decision-making. This is a foundational concept in information systems—data alone has limited value; it must be processed into information to be useful for decision-making . ________________________________________ 4. What are the three types of data processing? A) Manual, automated, and hybrid B) Batch processing, online/real-time processing, and hybrid processing C) Sequential, random, and indexed D) Input, processing, and output Answer: B Rationale: The three types are batch processing (transactions grouped and processed periodically), online/real-time processing (transactions processed immediately), and hybrid processing (a combination of both methods). The choice of processing method affects the timeliness and accuracy of information . ________________________________________ 5. What is batch processing? A) Processing transactions immediately as they occur B) A method where transactions are accumulated over a period and processed together as a group at scheduled intervals C) Processing transactions one at a time in sequence D) Processing transactions without any internal controls Answer: B Rationale: Batch processing is a method where transactions are accumulated over a period and processed together as a group at scheduled intervals, such as daily or weekly payroll processing. Batch processing is cost-effective for high-volume, repetitive transactions where real-time updates are not required . ________________________________________ 6. What is real-time processing? A) Processing transactions in batches at the end of the day B) Processing transactions immediately as they occur, providing instant updates and immediate feedback C) Processing transactions only at month-end for reporting purposes D) Processing transactions weekly in groups Answer: B Rationale: Real-time processing processes transactions immediately as they occur, providing instant updates to the system and immediate feedback to users, such as ATM withdrawals. Real-time processing provides current information but requires more system resources and is typically more expensive to implement . ________________________________________ 7. What are master files in an AIS? A) Temporary files containing transaction data B) Permanent files containing relatively stable data about entities such as customers, employees, inventory items, and vendors C) Files containing only financial statements D) Files containing budget information Answer: B Rationale: Master files are permanent files containing relatively stable data about entities such as customers, employees, inventory items, and vendors that are updated periodically. Master files serve as the authoritative source for key business data and are updated as transactions occur . ________________________________________ 8. What are transaction files? A) Permanent files containing master data B) Temporary files containing data about business events and transactions that update master files C) Files containing only financial statements D) Files containing budget projections Answer: B Rationale: Transaction files are temporary files containing data about business events and transactions that update master files, such as sales orders, purchase orders, and cash receipts. Transaction files capture the day-to-day business activities and are used to update the master files . ________________________________________ 9. What is data redundancy? A) The process of backing up data for security purposes B) The storage of the same data in multiple locations within an information system C) The process of deleting duplicate data D) The encryption of sensitive information Answer: B Rationale: Data redundancy is the storage of the same data in multiple locations within an information system, which can lead to inconsistencies and inefficiencies. Redundancy increases storage costs and can create data integrity issues when updates are not properly synchronized across all locations .
