System Analysis And Design MCQ Questions & Answers | Computer Science

The correct option is "response time".

Elapsed time between initiating a query and receiving the response is defined as response time.

It measures how quickly the system reacts to a user’s request and provides the output.

Why not the others?

"Waiting time" refers to the time a process spends in the ready queue before execution, not the query-response gap.

"Processing time" is only the time taken by the CPU to process instructions, not including the full elapsed query-response duration.

"Turnaround time" is the total time taken from submission of a process to its completion, which is broader than just query-response.

"None of the above" is incorrect because "response time" exactly matches the definition.

Therefore, the most accurate answer is "response time".

The correct answer is (B) controlling.
Let's break down why:

System Study Overview: A system study involves a thorough examination of an existing system (or a proposed new one) to understand its strengths, weaknesses, and areas for improvement.

Now let's look at the options in the context of a system study and management's role:

(A) planning: While planning is important, during the system *study* itself, the main activity isn't creating new plans. Planning happens more before and after the study.

(B) controlling: Controlling, in this context, means ensuring that the system study is conducted properly, stays on track, meets its objectives, and aligns with the organization's goals. Managers oversee the process, monitor progress, and make adjustments if needed. They are making sure the study is yielding useful information.

(C) directing: Directing involves telling people what to do. While managers provide some direction, during a study, their primary role is to *oversee* and *monitor* (control) the process, not micromanage every step.

(D) organizing: Organizing, like planning, is something that happens *before* the system study really gets going. It involves setting up the team, resources, and structure for the study.

(E) None of the above: This is incorrect because 'controlling' accurately describes the management role during the system study.

Therefore, executive vice-presidents and other managers are exercising their responsibility of *controlling* the system study process to ensure it's effective and beneficial for the organization.

A modular approach is a desirable characteristic of good system design.

Modular design involves dividing a system into smaller, manageable modules or components, each of which can be developed, tested, and maintained independently.

This approach enhances the flexibility, scalability, and maintainability of the system, making it easier to troubleshoot, upgrade, and extend.

Therefore, Good system design = Modular approach.

The correct option is "manual operation symbols".

In a systems flowchart, the manual operation symbol is used to represent activities that are performed by a person rather than a machine or automated system.

When input data is kept manually in an online system, it indicates human involvement in recording or handling the data. This is exactly represented by the manual operation symbol in flowcharting standards.

Why not the others?

"Online storage symbol" represents data stored in an online medium, not the manual act of keeping data.

"Online keyboard symbol" is used for data entry through a terminal or keyboard, not for manual handling of records.

"Keeping operation symbols" is not a recognized standard in system flowcharting.

"None of the above" is incorrect because the correct symbol exists and is manual operation symbols.

Therefore, the correct answer is manual operation symbols.
