AIS Fundamentals & Core Concepts (Questions 1-10)
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
Correct 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
Correct 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
Correct 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
Correct 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
Correct 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
Correct 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
Correct 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
