RBSE Class 12th 2011 Business Information System & Application-SS-37-1-2011 Previous Year Papers

सही उत्तर (Correct Answer): (अ) औपचारिक (A) Formal

व्याख्या (Explanation): मानव निर्मित सूचना तंत्र (Manmade Information System) औपचारिक (Formal) होता है क्योंकि यह संगठन द्वारा निर्धारित नियमों और प्रक्रियाओं पर आधारित होता है। अनौपचारिक तंत्र मानव निर्मित नहीं होता, बल्कि सामाजिक संबंधों से उत्पन्न होता है।

सही उत्तर (Correct Answer): (द) इनमें से सभी (D) All of these

व्याख्या (Explanation): नियंत्रण प्रणाली (Control System) में इनपुट (Input), प्रक्रिया (Processing), और आउटपुट (Output) तीनों कार्य शामिल होते हैं। यह प्रणाली इनपुट लेती है, उसे प्रोसेस करती है, और आउटपुट उत्पन्न करती है, जिससे नियंत्रण संभव होता है।

सही उत्तर (Correct Answer): (अ) प्रबंधीय नियंत्रण सूचनाएँ (A) Management control information

व्याख्या (Explanation): मध्यम स्तरीय प्रबंध (Middle Level Management) प्रबंधीय नियंत्रण सूचनाओं (Management Control Information) से संबंधित होता है, जो संगठन के मध्यम स्तर पर नियोजन और नियंत्रण में सहायता करता है। युक्तिय नियोजन सूचनाएँ उच्च स्तर पर और संक्रियात्मक सूचनाएँ निम्न स्तर पर उपयोग होती हैं।

सही उत्तर (Correct Answer): (स) (अ) तथा (ब) दोनों (C) Both (A) and (B)

व्याख्या (Explanation): निर्णय लेने के लिए डाटा सही प्रक्रिया द्वारा (By correct process) प्राप्त होना चाहिए और पूर्णतः शुद्ध (Completely accurate) होना चाहिए। दोनों शर्तें आवश्यक हैं ताकि निर्णय सटीक और विश्वसनीय हो सके।

Answer: A processor (or system) is a set of interrelated components that work together to achieve a common goal. It takes input, processes it, and produces output. In computing, a processor (CPU) is the central unit that executes instructions and performs calculations.

Answer: Structured design is a systematic approach to designing a system by breaking it down into smaller, manageable modules or components. It emphasizes top-down decomposition, modularity, and clear interfaces between modules to ensure maintainability and clarity.

Answer: An organisation is a structured group of people working together to achieve common objectives. It involves defined roles, responsibilities, and relationships, along with processes and resources to coordinate activities effectively.

Answer: D.S.S. stands for Decision Support System. It is an interactive computer-based system that helps managers make decisions by using data, models, and analytical tools to solve semi-structured or unstructured problems.

Answer: Post-implementation review is the process of evaluating a system after it has been deployed and is in use. It assesses whether the system meets its objectives, performs as expected, and identifies areas for improvement or modification based on user feedback and operational data.

Answer: Management Information System (M.I.S.) provides several benefits to an organisation. Four key benefits are:

1. Improved Decision-Making: M.I.S. provides timely, accurate, and relevant information to managers, enabling better and faster decisions.
2. Enhanced Efficiency: It automates routine tasks, reduces manual effort, and streamlines data processing, leading to higher operational efficiency.
3. Better Coordination: M.I.S. integrates information from different departments, facilitating communication and coordination across the organisation.
4. Strategic Advantage: By providing insights into trends and performance, M.I.S. helps organisations identify opportunities and gain a competitive edge.

Answer: A system consists of several key elements that work together:

• Input: Resources (data, materials, energy) that enter the system for processing.
• Process: The transformation or conversion of inputs into outputs through defined operations.
• Output: The final result or product generated by the system.
• Feedback: Information about the output that is used to adjust and control the system's performance.
• Control: Mechanisms that monitor and regulate the system to ensure it meets its objectives.
• Environment: External factors that influence the system but are outside its direct control.

Answer: Information is processed data that is meaningful, useful, and relevant for decision-making. It is data that has been organized, structured, or interpreted to add value.

Characteristics of information:

• Accuracy: Information must be correct and free from errors to be reliable.
• Timeliness: It should be available when needed to support decisions.
• Relevance: Information must be pertinent to the user's needs and context.
• Completeness: It should provide all necessary details without gaps.
• Consistency: Information should be uniform and not contradictory across sources.
• Accessibility: It should be easily retrievable and understandable by the intended user.

Answer: The differences between planning information and control information are:

Answer: A system is a set of interconnected components that work together to achieve a common goal. It takes inputs, processes them, and produces outputs while interacting with its environment.

Difference between open and closed systems:

Answer: In system design, logical and physical design are two stages:

• Logical Design: This focuses on the conceptual structure of the system, defining what the system does without considering implementation details. It includes data flow diagrams, entity-relationship models, and process specifications. It answers "what" the system needs to accomplish.
• Physical Design: This translates the logical design into actual hardware, software, and technical specifications. It includes database schemas, programming languages, network configurations, and user interfaces. It answers "how" the system will be built and implemented.

Answer: Information gathering tools are techniques used to collect data for system analysis and design. Common tools include:

• Interviews: Direct conversations with stakeholders to gather detailed insights.
• Questionnaires: Structured forms to collect data from a large number of respondents.
• Observation: Watching processes and user interactions to understand current workflows.
• Document Analysis: Reviewing existing reports, manuals, and records to extract relevant information.
• Focus Groups: Group discussions to explore opinions and ideas.
• Sampling: Collecting data from a representative subset of the population.

Answer: A feasibility study is an assessment of the practicality and viability of a proposed system or project. It evaluates whether the project can be successfully implemented within given constraints.

Types of feasibility study:

• Technical Feasibility: Assesses whether the required technology, hardware, software, and technical expertise are available or can be acquired to build the system.
