VERIFIED ANSWERS /EXPERT VERIFIED /ALREADY GRADED A+
Question 1
Which component of an Information System is considered the "bridge" between the computer-
side (hardware/software) and the human-side (people/procedures)?
A) Data
B) Networking
C) Input Devices
D) Middleware
E) Operating Systems
Correct Answer: A) Data
Rationale: Information systems consist of five components: hardware, software, data,
procedures, and people. Hardware and software are the technical side, while people and
procedures represent the human side. Data serves as the bridge between these two worlds;
it is stored and processed by the technology but created and used by the people following
specific procedures.
Question 2
A company uses a system that integrates all aspects of their business, including finance, human
resources, and manufacturing, into a single, unified database. What is this type of system called?
A) Customer Relationship Management (CRM)
B) Enterprise Resource Planning (ERP)
C) Decision Support System (DSS)
D) Transaction Processing System (TPS)
E) Knowledge Management System (KMS)
Correct Answer: B) Enterprise Resource Planning (ERP)
Rationale: ERP systems are designed to integrate internal and external management
information across an entire organization. By using a single database, an ERP allows
different departments (like accounting and production) to share information in real-time,
reducing data silos and improving operational efficiency.

Question 3
Which of Porter’s Five Forces is most concerned with the ease with which a customer can stop
buying from one company and start buying from a competitor?
A) Threat of New Entrants
B) Bargaining Power of Suppliers
C) Rivalry Among Existing Competitors
D) Threat of Substitutes
E) Bargaining Power of Buyers
Correct Answer: E) Bargaining Power of Buyers
Rationale: The Bargaining Power of Buyers refers to the pressure customers can exert on a
business. If "switching costs" are low—meaning it is easy and cheap for a customer to
move to a competitor—the buyer power is high. Information systems, such as loyalty
programs, are often used to increase switching costs and reduce buyer power.
Question 4
What does Moore’s Law suggest about the progression of computer hardware?
A) The cost of data storage doubles every 18 months.
B) The speed of internet connections increases tenfold every decade.
C) The number of transistors on a microchip doubles approximately every two years.
D) Software complexity increases at the same rate as hardware speed.
E) Battery life in mobile devices will decrease as processors get faster.
Correct Answer: C) The number of transistors on a microchip doubles approximately every
two years.
Rationale: Named after Gordon Moore, this observation has held true for decades, leading
to the exponential increase in processing power and the simultaneous decrease in the cost of
computing. This trend allows Information Systems to become smaller, faster, and more
affordable over time.
Question 5
Which of the following is an example of an "As-Is" process in business process management?
A) A diagram showing how the process currently functions.
, 3
B) A plan for how the process will be improved next year.
C) A simulation of a theoretical process.
D) A list of requirements for a new software system.
E) A benchmark comparison against a competitor's process.
Correct Answer: A) A diagram showing how the process currently functions.
Rationale: In Business Process Modeling, the "As-Is" model represents the current state of
the process without any changes. This is a critical first step because a team must fully
understand the current workflow and its bottlenecks before they can design the "To-Be"
(improved) process.
Question 6
A Decision Support System (DSS) is primarily intended to assist which level of management?
A) Operational (Lower) Management
B) Tactical (Middle) Management
C) Executive (Upper) Management
D) External Stakeholders
E) Both A and D
Correct Answer: B) Tactical (Middle) Management
Rationale: While DSS can be used at various levels, it is most characteristic of middle
management. DSS helps managers deal with "semi-structured" problems (like budgeting
or sales forecasting) by combining data with analytical models to explore different "what-
if" scenarios.
Question 7
Which type of software is responsible for managing the computer's hardware resources and
providing a platform for application software to run?
A) Firmware
B) Utility Software
C) Operating System
D) Enterprise Software
E) Database Management System
, 4
Correct Answer: C) Operating System
Rationale: The Operating System (OS), such as Windows, macOS, or Linux, acts as the
primary interface between the user, the application software, and the hardware. It manages
the CPU, memory, and storage, ensuring that multiple applications can run simultaneously
without crashing the system.
Question 8
Which cloud computing model provides only the basic building blocks like servers, storage, and
networking, leaving the user responsible for installing the operating system and applications?
A) Software as a Service (SaaS)
B) Platform as a Service (PaaS)
C) Infrastructure as a Service (IaaS)
D) Data as a Service (DaaS)
E) Desktop as a Service (DaaS)
Correct Answer: C) Infrastructure as a Service (IaaS)
Rationale: IaaS offers the most flexibility and control. The provider hosts the hardware, but
the client must manage everything from the OS level up. In contrast, PaaS provides a
platform for developers to build apps without managing the OS, and SaaS provides a fully
finished software product over the web.
Question 9
What is the primary purpose of a "Primary Key" in a relational database table?
A) To encrypt the data in the table.
B) To connect two different databases together.
) To uniquely identify each record (row) in the table.
D) To sort the data in alphabetical order.
E) To provide a description of the table's contents.
Correct Answer: C) To uniquely identify each record (row) in the table.
Rationale: In a relational database, every row must be unique. A Primary Key (such as an
Employee ID or Social Security Number) ensures that no two rows are identical and allows
the database to create relationships between different tables (via Foreign Keys).
