System Analysis And Design Quiz 1

A subsystem is a much smaller system that is subsumed in a larger system.

This statement is true because a system is indeed a collection of interconnected elements that work together to perform a specific activity, function, or operation. These elements can be physical components, software, or even abstract concepts. The interconnections between these elements allow them to communicate and cooperate in order to achieve a common goal or purpose. Therefore, the given statement accurately defines what a system is.

Data refers to "raw" unevaluated figures taken from the environment that could be used to produce information. It is the collection of facts, statistics, or information that can be analyzed or interpreted to gain insights or knowledge. Data is the foundation upon which information is built, and it needs to be processed, organized, and analyzed to become meaningful and useful.

A system analyst is a trained professional who can assist an organization in planning for system change for improved services. They have the expertise to analyze the current system, identify areas for improvement, and suggest solutions that can enhance the organization's services. They play a crucial role in understanding the organization's needs, gathering requirements, and designing new systems or making modifications to the existing ones. Their goal is to ensure that the system changes align with the organization's objectives and result in improved efficiency and effectiveness.

The correct answer is "data file". A data file is a body of information that is organized for a particular application or limited series of applications. It is a collection of related data stored in a structured format.

The given question is asking for the term that matches the description of "The observance, understanding, and evaluation of the interactions which routinely occur as part of the job investigation which the analyst much achieve". The correct answer is "assessment objective" because it aligns with the idea of evaluating interactions and understanding job investigations.

A computer program is a set of electronic instructions that tells the computer what to do. It is a sequence of commands and statements written in a programming language that the computer can understand and execute. It is the term commonly used to refer to this set of instructions.

The term "query" is used to refer to a valid electronic request for record search and retrieval in an information system. It is a common term in databases and information retrieval systems where users can input specific search criteria or parameters to retrieve relevant data. "Search criteria," "search option," and "data request" are not specific terms used to denote this type of electronic request.

A database system is a type of business software that allows users to accept, store, and retrieve data based on specific criteria. This software is designed to efficiently manage and organize large amounts of data, making it easy for users to access the information they need. With a database system, operators can input data, store it in a structured manner, and retrieve it later by applying filters or search criteria. This functionality makes it an essential tool for businesses to manage and analyze their data effectively.

The explanation for the given answer is that locality refers to a specific area or region, rather than a world where all systems interact. Therefore, the statement that locality is referred to as a world where all systems interact is incorrect.

Ada Augusta Lovelace is considered as the first programmer because she is credited with writing the world's first algorithm for a machine, specifically for Charles Babbage's Analytical Engine. She recognized the potential of the machine beyond mere calculations and understood that it could be used for various purposes, including creating complex programs. Her work laid the foundation for modern computer programming and she is often referred to as the "Enchantress of Numbers."

System Analysis is the correct answer because it involves studying the network of interactions within an organization and assisting in the development of new and improved methods for performing necessary work. This process helps in identifying inefficiencies, bottlenecks, and areas for improvement within the organization's systems and processes. By analyzing the existing systems and workflows, system analysts can recommend changes and enhancements to optimize performance, increase productivity, and achieve organizational goals.

Feedback is the information gained by the system after it has created and sampled its output to determine its effect. This information is used to apply corrective action if necessary. Feedback allows the system to evaluate its performance and make adjustments to improve its output or behavior. It is an essential component in the process of continuous improvement and optimization.

The statement is false because the word "system" in system analysis does not necessarily mean either a computer system or a group of computer programs. System analysis is a broader concept that involves analyzing and understanding any kind of system, whether it be a computer system, a business system, or any other type of system.

The main storage area of an electronic information system is referred to as a repository. This is where all the data and information are stored and organized. The repository serves as a central location for accessing and managing the information within the system. It is typically a dedicated storage system designed to handle large amounts of data and provide efficient retrieval and storage capabilities. The other options mentioned, such as hard disk, backup drive, and network drive, are all types of storage devices or locations that can be used to store data, but they do not specifically refer to the main storage area of an electronic information system.

The statement is false because system analysis is not a comprehensive process that includes system implementation. System analysis focuses on understanding and defining the requirements and objectives of a system, while system implementation involves the actual development and deployment of the system.

An open system is a characteristic of a system that interacts with its environment by receiving inputs and producing outputs. Unlike a closed system, an open system is dynamic and adaptable, allowing for the exchange of information, energy, and resources with its surroundings. This interaction with the external environment enables the system to respond to changes, learn from feedback, and evolve over time.

The use of computers in an organizational system is not required solely for the purpose of structuring information. While computers can certainly aid in organizing and storing information, they also serve many other functions such as data analysis, communication, automation, and decision-making support. Therefore, it is not true to say that the sole purpose of using computers in an organizational system is to structure information.
