Program Development Life Cycle (PDLC) Part 2

What are the key components of a computer system?

• Hardware, Software, Data, User, Network

• Monitor, Keyboard, Mouse, Printer

• Operating System, Application Software, Firmware, Middleware

• Router, Switch, Hub, Modem

What are sub-routines in software development?

• Modular components of a program that perform specific tasks or functions within a larger application.

• Randomly generated code snippets that execute without a defined purpose.

• Large blocks of code that handle all aspects of a program's functionality.

• Visual representations of data flow in software architecture.

What is the purpose of abstraction in top-down design?

• To allow for a clear understanding of what each module should accomplish.

• To increase the complexity of the design process.

• To eliminate the need for documentation.

• To ensure that all modules are identical.

What is the 'Output' in the context of problem decomposition?

• The process of breaking down a problem into smaller parts.

• The end result or output that should look like once the problem is solved.

• The initial step in problem-solving methodology.

• The tools used to analyze the problem.

What is stepwise refinement in top-down design?

• Breaking down a problem into smaller, manageable parts.

• Refining the top-level module into sub-modules and further into sub-sub-modules.

• Creating a detailed project timeline and milestones.

• Designing a user interface for the software application.

What is the function of the storage subsystem?

• It includes hard drives, SSDs, and other storage devices used to store data and software.

• It manages the CPU and memory resources of a computer.

• It provides a user interface for interacting with the operating system.

• It connects different hardware components to enable communication.

What does the principle of 'Divide and Conquer' refer to in top-down design?

• Dividing the problem into smaller, more understandable parts.

• Ignoring the problem and focusing on the solution.

• Combining multiple problems into one large problem.

• Solving the problem in a linear fashion.

What is the networking subsystem responsible for?

• It manages network connections and data transmission in a networked computer system.

• It handles user interface design and user experience.

• It stores data in a database and manages queries.

• It processes graphics and renders images for display.

What does 'Storage' refer to in problem decomposition?

• Considering where and how data should be stored during the process.

• The method of processing data in real-time.

• The technique of compressing data for efficiency.

• The analysis of data patterns and trends.

What is the significance of testing and integration in top-down design?

• Ensuring that each part of the system functions correctly before integrating it into the whole.

• To minimize the cost of development by skipping testing phases.

• To allow for rapid prototyping without any testing.

• To ensure that the final product is visually appealing.
