Question 1

Using CASE tools,UML,and other software to build working models of system components so that they can be quickly tested and evaluated is known as prototyping.

Accepted Answer

This statement is true. Prototyping is the process of using CASE tools, UML, and other software to build working models of system components that can be tested and evaluated quickly.

Question 2

During system implementation,the fifth phase of the SDLC,hardware,software,and files are converted to the new system,and users are trained.

Accepted Answer

During the implementation phase, hardware, software, and data are converted to the new system, and users are trained on how to use the new system.

Question 3

If the old and new systems are operated side by side until the new system has proven itself,this type of system conversion plan is parallel implementation.

Accepted Answer

Parallel implementation involves running the old and new systems simultaneously for a period of time until the new system has been thoroughly tested and proven to be successful.

Question 4

In the make-or-buy decision,the systems analyst decides whether to have a program custom written or to purchase an existing software package.

Accepted Answer

The make-or-buy decision involves deciding between custom programming and purchasing an existing software package, and the systems analyst is usually involved in this decision-making process.

Question 5

During the systems design phase,data is gathered,analyzed,and a report is written.

Accepted Answer

During the systems design phase, the focus is on defining how the system will work to meet the requirements identified in the systems analysis phase. Data gathering and analysis primarily occur in the systems analysis phase, not the design phase.

Question 6

CASE tools are used only in the systems analysis phase of the SDLC.

Accepted Answer

CASE tools can be used in various phases of the SDLC including requirements gathering, design, coding, testing, and maintenance.

Question 7

Modeling tools allow systems analysts to present graphic representations of a system.

Accepted Answer

Modeling tools like flowcharts, data flow diagrams, entity-relationship diagrams, and UML diagrams allow systems analysts to visually represent the components, processes, and relationships of a system.

Question 8

During systems design,the third phase of the SDLC,the systems analyst acquires the new software and hardware,and then tests the system.

Accepted Answer

During systems design, the third phase of the SDLC is actually the design phase, where the systems analyst creates the blueprints for the new system based on the requirements gathered from the previous phase. The acquisition of software and hardware and testing of the system typically occur in the next phase, which is the implementation phase.

Question 9

If the performance of a new system's individual parts is examined using test (made-up or sample)data,this is called component testing.

Accepted Answer

The answer of If the performance of a new system's...

Question 10

In the fourth phase of the SDLC,if a new system's parts are linked and test data is used to see if the parts work together,this is called system testing.

Accepted Answer

System testing is the process of testing the complete system once all of its components have been integrated to ensure that it meets its requirements and operates as expected. Test data is used to validate if the different parts of the system work effectively when combined.

Question 11

Prototyping,or building working models of new systems,is used in the first phase of the SDLC.

Accepted Answer

Prototyping is typically used in the later phases of the System Development Life Cycle (SDLC) to refine requirements and design, not in the first phase, which is usually dedicated to planning and requirements analysis.

Question 12

In the third phase of the SDLC,a detail design proposes how a proposed information system will deliver the general abilities that were described in the preliminary design of the first phase.

Accepted Answer

In the third phase, the detail design specifies how the proposed system will provide the intended functionalities identified in the preliminary design phase.

Question 13

Computer-based programs that automate various activities of the systems development life cycle in most phases of the SDLC are called computer-aided software engineering tools (CASE).

Accepted Answer

Computer-aided software engineering tools (CASE) are designed to automate various activities of the systems development life cycle in most phases of the SDLC.

Question 14

If a new system is being custom-written,then programming is part of the fourth phase of the SDLC.

Accepted Answer

Programming is part of the implementation phase, which is the fourth phase of the SDLC.

Question 15

The SDLC is the step-by-step process of systems analysis and design.

Accepted Answer

The SDLC (Systems Development Life Cycle) is indeed a step-by-step process used in systems analysis and design to ensure the development of a high-quality system that meets user requirements.

Question 16

During the systems design phase of the SDLC,a preliminary design,or a "rough draft," of the new system is done; then a detail design is done,and a report on the work is presented.

Accepted Answer

During the systems design phase, both a preliminary design and a detailed design are done, and a report on the work is presented.

Question 17

The first step of the SDLC is to design a new system.

Accepted Answer

The first step of the SDLC is usually to identify the problem or opportunity, followed by conducting a feasibility study and analysis before moving on to the design phase.

Question 18

A data flow diagram is not a modeling tool used to represent a new system.

Accepted Answer

A data flow diagram is a modeling tool used to represent the flow of data in a new system. It is a graphical representation that shows how data is input, processed and output in a system.

Question 19

A limited working system developed to test design concepts is a data flow model.

Accepted Answer

A limited working system developed to test design concepts is known as a prototype, not a data flow model. A data flow model is used to represent the flow of data through a system.

Question 20

SDLC stands for Systems Development Lifecycle Control.

Accepted Answer

SDLC stands for Systems Development Lifecycle, but "Control" is not part of the acronym.
