Q: 1 _________ are conceptual and non-physical entities that may be formulas, representation or model of a real system.
Physical Systems
Abstract Systems
Deterministic Systems
Probabilistic Systems
[ Option B ]
Abstract Systems are conceptual and non-physical entities that represent ideas, models, or formulas of real systems. They do not exist physically but serve as representations or theoretical constructs to study, analyze, or simulate how a real system functions.
Abstract Systems are conceptual, meaning they do not have a physical form. They exist as ideas, models, formulas, diagrams, or representations of a real system. Examples included, mathematical formulas, economic models, organizational charts, logical flow diagrams, theoretical computer models etc.
| TYPE OF SYSTEM | DESCRIPTION |
|---|---|
| Physical Systems | Tangible and material systems that exist in reality. |
| Abstract Systems | Conceptual or non-physical models or representations of real systems. |
| Deterministic Systems | Systems where outputs are precisely determined by inputs without randomness. |
| Probabilistic Systems | Systems with inherent randomness or uncertainty in outputs. |
| Open Systems | Systems that interact with their environment and exchange matter, energy, or information. |
| Closed Systems | Systems that do not interact with their environment. |
| Static Systems | Systems with outputs dependent only on current inputs, not time or past states. |
| Dynamic Systems | Systems where outputs depend on time and history of inputs, exhibiting behavior over time. |
Q: 2 The process of organizing subsystems so as to reduce the number of interconnections is termed as ________________.
Decomposition
Simplification
Regrouping
Decoupling
[ Option B ]
Simplification is the process of organizing subsystems in such a way that the number of interconnections between them is reduced. In system design, when a large system is broken down into smaller subsystems, each subsystem interacts with others through interfaces.
Simplification aims to minimize these connections, making the system easier to understand, maintain, and modify.
Q: 3 _______________ are computerized information systems that were developed to process large amount of data for routine business transactions such as payroll and inventory.
Knowledge Work Systems (KWS)
Group Decision Support System (GDSS)
Transaction Processing Systems (TPS)
Office Automated System (OAS)
[ Option C ]
Transaction Processing Systems (TPS) are computerized information systems designed to process large amounts of data related to routine business transactions such as payroll, inventory management, order processing, and billing.
TPS ensures efficient, reliable, and accurate processing of business transactions in real-time or batch mode. They maintain data integrity, rapid response, and controlled processing.
TPS SYSTEMS FOCUS ON:
Q: 4 Which of the following is not a characteristic of software?
Software is developed, not manufactured.
Software deteriorates over time.
Software wears out like hardware.
Software is intangible.
[ Option C ]
Unlike hardware, software does not physically wear out but may require updates due to evolving user needs or environment changes.
Q: 5 Mr. X is a member of System Development Team who visits his client company XYZ Ltd. frequently to interview its employees to gather the details regarding the drawbacks of the existing system in the company XYZ Ltd. and understand their future requirements. Identify the role Mr. X is performing.
Programmer
Project Leader
System Analyst
Project Manager
[ Option C ]
A System Analyst plays a key role in system development. Their primary responsibility is to study the existing system, understand its problems, and gather requirements for the new system.
Q: 6 The goal of requirements _______________ is to collect and document what various stakeholders want from the software that is to be built.
analysis
gathering
list
specification
[ Option B ]
The goal of Requirements Gathering is to collect and document the needs, expectations, and desires of various stakeholders regarding the software to be built. Requirements gathering is a critical early phase in software development focused on understanding what stakeholders want from the system. The collected information forms the basis for analysis, design, and implementation.
Q: 7 A ___________ is a record of historical data that remains in a file, used for reference and serves as control on key details.
Rewrite form
Report form
Memory form
Record form
[ Option C ]
Q: 8 ____________ refers to the automation of anything that humans do to develop systems and supports virtually all phases of Traditional System Development Process.
Decision Tree
Computer-Aided-Software Engineering (CASE)
System Flow Charts
Data Flow Diagram
[ Option B ]
System Development involved manual processes which were time-consuming and prone to errors. CASE tools provide an environment where activities such as diagramming, code generation, version control, and testing are partially or fully automated.
Computer-Aided Software Engineering (CASE) refers to the use of software tools that automate many activities humans perform during system development.
Compared to a Data Flow Diagram (DFD), which simply shows the movement of data in a system and is used only in the analysis phase, CASE tools work throughout all phases of SDLC.
Q: 9 The primary goal of System Analysis is to:
Design the system interface.
Understand user requirements and system needs.
Code the software program.
Implement the system.
[ Option B ]
System analysis focuses on gathering and understanding user requirements and identifying system problems before design and implementation begin.
Q: 10 Software Engineering is mainly concerned with:
Hardware development.
Ad-hoc programming.
Systematic software development using engineering principles.
Testing only.
[ Option C ]
Software Engineering applies engineering methods and systematic approaches to software development, ensuring quality and reliability.
Q: 11 The interconnections and interactions between the sub-systems are termed as ______________.
Connectors
Interfaces
Protocols
Links
[ Option B ]
In a system, you have multiple sub-systems (smaller parts) that work together. For these sub-systems to exchange data, signals, or control information, they must be connected in a meaningful way. This connection is called an Interface. An interface specifies:
Q: 12 Which one of the following correctly defines a System?
System may be defined as a group of two or more interrelated components or sub-systems that serve a common purpose.
System may be defined as a group of two or more interrelated components or sub-systems that function independently of the others and do not contribute to the common goal.
System may be defined as a group of two or more interrelated components or sub-systems that do not serve a common purpose.
System may be defined as a group of elements that operate in a predictable manner.
[ Option A ]
A System is fundamentally a collection of interrelated components working together to achieve a common goal. These components or subsystems interact and depend on each other to produce a unified output or outcome.
