Explanation
The given statement is true. S.A.D stands for System Analysis and Design. This field involves studying and analyzing existing systems and designing new ones to improve efficiency, productivity, and overall performance. System Analysis and Design professionals use various techniques and tools to identify system requirements, develop models, and create solutions that meet the needs of organizations.

Explanation
The statement is true because in every system, there are three major components: input, processing, and output. Input refers to the data or information that is entered into the system, processing involves manipulating or analyzing the input data, and output is the result or outcome of the processing. These components are essential for the functioning of any system as they enable the flow of information and the execution of tasks.

Explanation
The statement is false because the System Life Cycle is indeed an organized process of developing and maintaining a system. It involves different phases such as planning, analysis, design, implementation, and maintenance, which are followed in a systematic manner to ensure the successful development and functioning of a system.

Explanation
The statement is true because the System Development Life Cycle (SDLC) and the Software Development Life Cycle (SDLC) are often used interchangeably to refer to the same process. Both terms describe the systematic approach to developing software, which includes stages such as requirements gathering, design, coding, testing, and maintenance. The SDLC encompasses the entire process of developing a system, which includes software development as one of its components. Therefore, it is correct to say that the SDLC means the SDLC.

Explanation
A preliminary study is not the second phase of the life cycle. The term "preliminary" suggests that it is an initial or preparatory stage that comes before the actual phases or stages of the life cycle. Therefore, the correct answer is false.

Explanation
A feasibility study is indeed a test of the proposed system. It is a process that evaluates the practicality and viability of a project or system. It assesses various factors such as technical, economic, legal, operational, and scheduling aspects to determine if the proposed system can be implemented successfully. The study helps in identifying potential risks, benefits, and limitations of the project, enabling stakeholders to make informed decisions about its feasibility. Therefore, the statement is correct.

Explanation
Interviews, onsite observation, and questionnaires are commonly used tools for conducting a detailed system study. Interviews involve direct communication with stakeholders to gather information and insights. Onsite observation allows researchers to observe the system and its users in their natural environment, providing a deeper understanding of the system's functioning. Questionnaires are a structured way to collect data from a large number of participants. These tools are valuable in gathering comprehensive information and analyzing the system's requirements, processes, and user needs. Therefore, the statement is true.

Explanation
The statement is incorrect because system analysis is indeed a process of collecting factual data. System analysis involves gathering information about the existing system, understanding its components, and identifying its strengths and weaknesses. This data collection is essential for analyzing the system and proposing improvements or designing a new system. Therefore, the correct answer is False.

Explanation
System analysis is the process of studying and understanding the current business processes in order to identify areas for improvement or optimization. By analyzing the system, the objective is to find answers or solutions to the problems or inefficiencies in each business process. Therefore, the statement "The major objective of system analysis is to find answers for each business process" is true.

Explanation
System Design typically proceeds in multiple phases, not just three. The number of phases may vary depending on the specific methodology or approach being followed. However, it is common for system design to involve several stages such as requirements gathering, analysis, architectural design, detailed design, implementation, and testing. Each phase has its own objectives and activities, contributing to the overall development process. Therefore, the statement that system design normally proceeds in three phases is incorrect.

Explanation
Programming and coding are often used interchangeably, but they are not the same thing. Coding refers to the process of writing instructions in a specific programming language to create a software or application. On the other hand, programming encompasses a broader set of activities that include problem-solving, algorithm design, and planning the overall structure of the software. Therefore, programming is indeed a part of coding, making the given answer "False" correct.

Explanation
The statement is true because in order to have a functional system, the design needs to be implemented. System design involves planning and organizing the various components and processes of a system to ensure it meets the desired requirements and functions effectively. Without implementing the design, the system would not be able to perform its intended tasks and would not be considered workable. Therefore, the correct answer is true.

Explanation
Before implementing a new system into operation, it is common practice to conduct a test run of the system. This allows for any potential issues or bugs to be identified and resolved before the system is fully implemented. By conducting a test run, organizations can ensure that the system functions as intended and meets the requirements of the users. This helps to minimize disruptions and maximize the effectiveness of the new system once it is implemented.

Explanation
During the implementation stage of a project, the theoretical plans and strategies are put into action. This is the phase where the project team executes the tasks, utilizes the resources, and applies the techniques to achieve the project objectives. It involves the actual implementation of the project plan and the practical application of the project methodologies. Therefore, the statement "Implementation is the stage of a project during which theory is turned into practice" is true.

Explanation
Maintenance is necessary to eliminate errors in the system during its working life. Without regular maintenance, errors can accumulate and cause system failures or malfunctions. Regular maintenance helps identify and fix any issues or errors that may arise, ensuring the system operates smoothly and efficiently. Therefore, the statement that maintenance is not necessary to eliminate errors in the system is false.

Explanation
Structured Design refers to the process of creating a plan or blueprint for a computer system solution to a specific problem. It involves breaking down the problem into smaller components and designing the system in a logical and organized manner. This approach helps in creating a clear and efficient solution that can be easily implemented and understood. Therefore, the statement "Structured Design is a blueprint of a computer system solution to a given problem" is true.

Explanation
System testing is an essential part of the implementing process. It involves testing the entire system as a whole to ensure that all components work together correctly and meet the specified requirements. This testing phase helps identify any issues or defects in the system before it is deployed to users. Therefore, it is incorrect to say that system testing is not a part of the implementing process.

Explanation
System Analysis and Design is a discipline that focuses on the process of developing software systems. It involves activities such as gathering requirements, designing system architecture, creating detailed specifications, and implementing and testing the software. Therefore, it can be concluded that System Analysis and Design primarily deal with software development activities.

Explanation
The statement is true because return on investment (ROI) refers to the measure of profitability or efficiency of an investment. It calculates the return or gain on an investment relative to its cost. In this context, ROI is used to determine the resources required to complete a detailed investigation, implying that it helps assess the potential benefits and costs associated with the investigation. Therefore, the statement accurately states that ROI defines the resources needed for the investigation.

Explanation
The statement is true because studying the performance of a system is indeed an important part of maintenance. By analyzing the system's performance, one can identify any issues or areas that need improvement. This allows for proactive maintenance and helps ensure that the system operates efficiently and effectively.
