Q1. Explain the functional units of the 8086 Microprocessor and discuss the role of Bus Interface Unit (BIU) and Execution Unit (EU).

Ans 1.

The Intel 8086 is a 16-bit microprocessor introduced in 1978. It was the earliest member of the x86 family and became the base for current personal computing designs. The 8086 can be internally split into two independent, operational units that are parallel: the Bus Interface Unit (BIU) and the Execution Unit (EU). This division permits instructions fetching and execution to work together, dramatically increasing the speed of execution compared to previous processors.

Q2. Discuss the problem of forward references in a single pass assembler. How are undefined symbols handled?

Ans 2.

An assembly converts programming into machine code. Most assemblers operate in two successive passes through the source code. A two-pass assembler can resolve all symbols definitions during the initial pass, and then generates object code during the second. An assembler that is single-pass, attempts to generate object code with just one pass through the source code. While this is faster and more efficient with memory However, it presents a serious

Q1. a. Explain the dual aspect concept and the matching concept in accounting.

1. Explain the importance of financial statements. 5 + 5

Ans 1.

1. Dual Aspect Concept

The dual aspect concept is the foundation of modern double-entry accounting. It states that every business transaction has two aspects—a giving aspect and a receiving aspect—which must be recorded equally. This concept ensures that the accounting equation Assets = Liabilities + Capital always remains in balance. For example, when a business purchases machinery worth ₹50,000 for cash, there is an increase in assets (machinery) and a decrease in another asset (cash). Similarly, if goods are sold on credit, the business receives a debtor and gives away stock. This dual effect maintains accuracy, prevents manipulation, and ensures that financial books reflect the true financial position. It also forms the basis for preparing trial balances and financial

Q5. Explain the principles of pipelining and analyze potential hazards (Structural, Data, and Control) that can impede instruction throughput. Compare the Superscalar and VLIW (Very Long Instruction Word) models regarding their approach to instruction-level parallelism and scheduling

Ans 5.

Part A: Pipelining and Hazards

Pipelining is a method that lets multiple instructions be handled simultaneously, by splitting the execution into steps. Each stage is responsible for a specific part of an instructions’ execution. As one instruction is performed, another is decoded and the next one is fetched. The overlap can increase instruction speed substantially, but does not necessarily increase the rate of the clock.

The classic five-stage pipeline comprises Instruction Fetch, Instruction Decode, Execute,

Q.4. a) Define a List in Python. Explain list operators and built-in functions used with lists. b) What are Sets and Dictionaries? Write the syntax for creating and calling a function in Python. (5+5 = 10 Marks)

Ans 4.

1. a) Python List — Operators and Built-in Functions

In Python a List is an ordered collection of items that supports heterogeneity of data types and can be indexed or iterated, and is mutable. Lists are made with square brackets.Square brackets are used to make lists. Example: nums = [10, 20, 30, 40, 50]. Lists can have duplicate values, and

Q.5. Explain try-except statements, multiple exceptions, and raise exceptions with examples. Write a program to create custom exception in Python. (10 Marks)

Ans 5.

In Python, exception handling is a well-defined and robust way to identify, handle, and recover from runtime errors (exceptions) gracefully, avoiding abrupt program termination and offering meaningful error messages to the users and developers. If the programmer fails to write exception handlers, the program would crash on the fly, lose any unsaved data and user

Q.6. a) Explain database connectivity in Python using SQL. b) What are Python packages? Explain use of pandas and numpy in data handling with example. (5+5 = 10 Marks)

Ans 6.

1. a) Database Connectivity in Python using SQL

Python connects to relational databases using the DB-API 2.0 standard. The most popular library for MySQL is mysql-connector-python. If using the built-in SQLite, which is included with Python, it needs to be installed. When the database connection process is performed, it takes the following steps:

The Python database connectivity is based on the PEP 249 standard (DB-API 2.0), making it

Q.1. Discuss the evolving role and characteristics of software and explain how different software development models such as Linear, Iterative, Incremental, and Concurrent models address modern software development challenges. (3+3+4 = 10 Marks)

Ans 1.

Evolving Role and Characteristics of Software

Software has grown from a simple batch processing programs in the 1950s, to more complex, interconnected systems that underpin the entirety of life in the present. Modern software is distinguished by its increasing complexity, its distributed structure, requirements for real-time processing important for business operations as well as safety-critical system. Key characteristics

Q.2. Explain the concept of software reliability and discuss how software design principles including system models and architectural design contribute to improving reliability and overall software quality. (3+3+4 = 10 Marks)

Ans 2.

Software Reliability

Software reliability relates to the possibility that software will perform its functions in a correct manner under stipulated conditions for a specific duration of time, without causing failure. It’s one of the main aspects of software’s quality, specifically in safety-critical systems like aviation, medical devices banks, telecommunications, and other fields. It is different from the accuracy A

Q.3. Describe Object-Oriented Design concepts such as object interface design, service usage, and structural decomposition. Further, evaluate the assessment of process life-cycle models and the importance of business models in software engineering. (3+3+4 = 10 Marks)

Ans 3.

Object-Oriented Design Concepts

Object-Oriented Design (OOD) extends analysis using Object-Oriented Design to create specific design specifications for software components that are identified in the study. Object Interface Design defines the particular interfaces that every class or object exposes its service to objects of other types, listing the signatures of methods, input parameters, return types, as well as post-

Q.4. Explain Software Configuration Management including change management, version and release management, and software maintenance. Discuss white-box, black-box testing, and boundary value analysis. (2+3+3+2 = 10 Marks)

Ans 4.

Software Configuration Management (SCM)

Software Configuration Management is the process of consistently monitoring and controlling the changes made to software products through the entire life cycle of software. Its aim is to preserve the integrity and traceability of software throughout the entire lifecycle of development and maintenance history.

Change Management

Change management establishes a procedure for making and approving, evaluating, the

Q.5. Discuss Software Testing Assurance including Verification & Validation, test planning, and testing tools. Explain unit testing, top-down and bottom-up integration testing. (5+5 = 10 Marks)

Ans 5.

Software Testing Assurance

Software Testing Assurance encompasses all processes that make sure software meets the specifications and exceeds the expectations of users prior to and following deployment.

Verification and Validation (V&V)

Verification asks ‘Are we building the product right?’ • ensuring that software correctly implements the specified design through reviews, inspections, and walkthroughs of the

Q.6. Compare traditional and modern software engineering approaches and analyse the role of software technology as an enabling and limiting business tool. Discuss how diversified problem-solving strategies contribute to effective software development. (3+3+4 = 10 Marks)

Ans 6.

Traditional vs Modern Software Engineering

The traditional software engineering approach, as illustrated through the Waterfall model, focuses on thorough initial planning, detailed documentation, a rigid phase gate, and continuous execution. Specifications are set before design begins, and changes following development start are expensive and can be disruptive. Traditional approaches work well in projects that have solid expectations, well-understood specifications and lengthy delivery timelines such as large
