Informatics System Analysis and Design (C798)

Correct Answer

A. Server clustering

Explanation

A server farm is a collection of networked servers that work together to provide computing resources and services. This is an example of server clustering, where multiple servers function as a single system to improve performance, scalability, and reliability. In a cluster, if one server fails, others can take over its tasks, ensuring continuity of service.

Why other options are wrong

B. Redundant servers

While redundancy is a feature of server farms, a server farm itself is not just about redundancy. Redundant servers are specifically extra backup servers that are available in case of failure, whereas a server farm is a larger-scale setup that improves processing power and efficiency.

C. Multiple servers

Although a server farm consists of multiple servers, this option is too general. The defining characteristic of a server farm is that the servers are clustered and work together to handle workloads efficiently.

D. Server fault tolerance

While server farms often include fault tolerance mechanisms, a server farm itself is not just about fault tolerance. Fault tolerance refers to a system's ability to continue functioning despite failures, whereas a server farm is a broader concept involving multiple interconnected servers working together.

Correct Answer

b. Project Plan

Explanation

The planning phase is crucial for setting the foundation of a project, and one of its key outcomes is the Project Plan. This document outlines the project scope, timeline, resources, budget, and risks. It serves as a roadmap for project execution, ensuring all stakeholders are aligned on objectives, responsibilities, and schedules. The Project Plan helps mitigate risks and provides a structured approach for completing the project successfully.

Why other options are wrong

a. Feasibility Analysis document

While this document is indeed part of the planning phase, it is not the only outcome. It primarily evaluates whether the project is viable, but it does not provide a structured execution roadmap like the Project Plan does.

c. System specification document

This document is produced in the design phase, not the planning phase. It provides a detailed technical description of how the system will be implemented but is not used for project scheduling or resource allocation.

d. System proposal document

The system proposal document is typically developed in the analysis phase. It presents findings from feasibility studies and system requirements but does not serve as a planning tool for project execution.

e. Business Process document

While business process documentation can be part of system analysis and requirements gathering, it is not a primary output of the planning phase. It focuses more on workflow optimization rather than project management and execution.

Correct Answer

b. The number of transistors on an integrated circuit chip will double approximately every two years.

Explanation

Moore’s Law, formulated by Gordon Moore in 1965, predicts that the number of transistors on a microchip will double roughly every two years, leading to exponential growth in computing power. This observation has driven rapid technological advancements and cost reductions in semiconductor manufacturing over the decades.

Why other options are wrong

a. The processing speed of computers will increase by 50% every year.

While transistor growth contributes to improved performance, Moore’s Law specifically refers to the doubling of transistors, not an exact increase in processing speed.

c. The cost of producing integrated circuits will decrease by 10% annually.

Moore’s Law does not directly state cost reductions. While production costs have decreased over time due to advancements in semiconductor technology, this is an indirect effect rather than a direct prediction of Moore’s Law.

d. The size of integrated circuits will remain constant over time.

On the contrary, integrated circuits have become smaller and more powerful over time, allowing for greater transistor density and improved performance.

Correct Answer

b. Communication.

Explanation

Systems analysis and design primarily focus on understanding business needs and translating them into functional technology solutions. Effective communication is crucial for gathering requirements, working with stakeholders, and ensuring that the final system meets business objectives. Analysts must communicate with users, developers, and management to align expectations and provide clarity throughout the development process.

Why other options are wrong

a. Technical prowess

While technical skills are valuable, systems analysis and design are more about problem-solving, communication, and understanding user needs rather than purely technical expertise.

c. Project management

Project management is important in guiding system development, but it is a separate discipline. Systems analysis and design involve broader responsibilities beyond just managing timelines and resources.

d. Adhering to processes no matter what

Processes provide structure, but flexibility is necessary to adapt to changes and new requirements. Strictly adhering to processes without considering user needs and system requirements can result in ineffective solutions.

Correct Answer

C. System

Explanation

System software is a collection of programs that manage hardware operations and provide a platform for running application software. It includes operating systems, utility programs, and device drivers, which ensure that hardware and software components function together efficiently.

Why other options are wrong

A. Application

Application software is designed for end-users to perform specific tasks, such as document editing or web browsing. It does not control hardware directly but instead operates within the framework provided by system software.

B. Transitory

"Transitory software" is not a recognized category of software. While software may have temporary or short-lived processes, the term "transitory software" does not specifically refer to a type of software that manages hardware operations.

D. Open source

Open source refers to the licensing model of software rather than a specific type of software. System software can be open source (e.g., Linux) or proprietary (e.g., Windows), but "open source" itself is not the type of software that controls hardware operations.

E. Peripheral

Peripheral devices are external hardware components such as printers, keyboards, and external storage devices. The term "peripheral software" is not commonly used to describe system software, which manages the core operations of computer hardware.

Correct Answer

B. To assist in the planning, development, and maintenance of information systems

Explanation

A systems analyst plays a critical role in the IT department by assessing business needs, analyzing current systems, identifying areas for improvement, and designing solutions that align with organizational goals. They work closely with stakeholders to gather requirements, create system specifications, and ensure that information systems are effectively developed and maintained.

Why other options are wrong

A. To oversee the entire IT infrastructure

While a systems analyst may be involved in certain aspects of IT infrastructure, overseeing the entire infrastructure is typically the responsibility of an IT manager or chief information officer (CIO).

C. To manage the company's financial resources

Financial resource management is the role of finance professionals and accountants, not systems analysts. A systems analyst focuses on technology solutions rather than budgeting and financial management.

D. To conduct market research for new software products

Market research is usually performed by business analysts, product managers, or marketing teams. A systems analyst is more concerned with designing, implementing, and maintaining IT systems rather than researching new software for external markets.

Correct Answer

E. Commerce server

Explanation

A commerce server is a specialized system designed to handle e-commerce operations, including retrieving product data from a database, managing user sessions, handling the shopping cart, and coordinating the checkout process. It provides the necessary infrastructure for processing online transactions securely and efficiently.

Why other options are wrong

A. Database management system

A database management system (DBMS) is responsible for storing and managing data but does not handle transaction processes such as shopping cart management or checkout coordination. The commerce server interacts with the DBMS to retrieve data but performs additional functions related to e-commerce operations.

B. Web server

A web server is responsible for delivering web pages to users but does not manage e-commerce functionalities such as handling shopping carts or coordinating checkout. It primarily serves static and dynamic content but relies on other systems to process transactions.

C. Web browser

A web browser is the software used by users to access the website but does not play a role in managing e-commerce transactions. It simply displays the web pages and allows users to interact with the site.

D. Internet server

The term "Internet server" is too broad and does not specifically refer to a system designed to handle e-commerce transactions. Internet servers can host websites, provide email services, or manage networking, but they are not specifically used for processing online shopping transactions.

Correct Answer

C. Iterative

Explanation

The iterative methodology is well-suited for projects where requirements are somewhat unclear, and the technology is somewhat unfamiliar. By breaking the project into smaller cycles, teams can gradually refine the system based on feedback and learning from previous iterations. This approach is particularly useful for complex projects with high schedule visibility, as stakeholders can see progress at each iteration.

Why other options are wrong

A. Waterfall

Waterfall is a linear methodology best suited for projects with well-defined requirements and stable technology. It lacks the flexibility needed for unclear requirements and unfamiliar technology.

B. Parallel

Parallel development speeds up delivery by developing different system components simultaneously, but it does not inherently handle unclear requirements well. It works best when requirements are well-defined.

D. System prototyping

System prototyping is helpful for gathering user feedback but is less effective for handling complexity and unfamiliar technology since it focuses more on user interface aspects than overall system architecture.

E. Throwaway prototyping

Throwaway prototyping helps clarify requirements before full development but is not as effective for projects involving complexity and unfamiliar technology.

Correct Answer

a. Raw facts that describe some phenomenon.

Explanation

Data consists of raw, unprocessed facts and figures that lack context or meaning. It can include numbers, text, or images collected from various sources. Only when processed and interpreted does data become meaningful information.

Why other options are wrong

b. Records that are stored in a database or transaction file.

While data can be stored in databases or files, this answer describes storage rather than the fundamental definition of data.

c. A collection or set of information about a particular person, object, or event.

This definition aligns more with information, which is processed data with context and meaning.

d. Information that has a particular meaning within a specific context.

This describes information, not data. Data is raw and unorganized until it is processed into meaningful information.
