Question 1

Define software. Enlist the characteristics of good software.

Accepted Answer

Software is a collection of executable computer programs, rigorous documentation, and operational procedures mathematically engineered to perform a specific computational task.

Question 2

Give the difference b/w FP and LOC.

Accepted Answer

LOC measures physical code size, while Function Points (FP) rigorously measure the actual computational functionality delivered to the end-user.

Question 3

What is SRS?

Accepted Answer

An SRS is a legally binding blueprint explicitly detailing the absolute functional and non-functional requirements of the proposed software system.

Question 4

Explain FSM model.

Accepted Answer

The Finite State Machine (FSM) model mathematically represents a software system as a strict set of states triggered by external events.

Question 5

Why accuracy is important attribute for a data dictionaries.

Accepted Answer

Accuracy in a Data Dictionary is critical because it acts as the singular, centralized source of truth for all database metadata.

Question 6

What is software Design. Write any Four Design principles.

Accepted Answer

Software design translates abstract requirements into a physical architectural blueprint using principles like abstraction, modularity, coupling, and cohesion.

Question 7

What is Input /Process/Output (IPO) approach in S/W Design.

Accepted Answer

The IPO approach strictly models every software subsystem as a black box receiving inputs, mathematically processing them, and generating outputs.

Question 8

What do you mean by OO concept. Write 3 OO principles.

Accepted Answer

Object-Oriented concepts model real-world entities using encapsulated data and behavior; core principles include Encapsulation, Inheritance, and Polymorphism.

Question 9

Explain the term Risk Analysis. Enlist Four major categories of Risk analysis.

Accepted Answer

Risk Analysis mathematically calculates the probability and financial impact of future project failures, categorized into Technical, Project, Business, and Known risks.

Question 10

Differentiate b/w object oriented analysis (OOA) and Object Oriented Design (…

Accepted Answer

OOA rigorously models "what" the system must do, while OOD aggressively defines exactly "how" the system will physically do it.

Question 11

What are the difference b/w verification and validation. Explain it with prop…

Accepted Answer

A definitive structural comparison between Verification ("Are we building the product right?") and Validation ("Are we building the right product?"), explaining their roles in the V-Model lifecycle.

Question 12

Explain Software Development life cycle model with appropriate diagram.

Accepted Answer

A comprehensive exploration of the Software Development Life Cycle (SDLC), detailing its strict sequential phases (Requirements, Design, Implementation, Testing, Maintenance) using the foundational Waterfall Model architecture.

Question 13

Explain spiral model of s/w Development with a labelled diagram, state advant…

Accepted Answer

An advanced architectural breakdown of Boehm’s Spiral Model, explicitly highlighting its unique, aggressive focus on mathematical risk analysis and iterative prototyping, alongside its corporate merits and severe financial demerits.

Question 14

What do you mean by DFD. Explain its type with proper diagram. Draw 0'level a…

Accepted Answer

A definitive structural guide to Data Flow Diagrams (DFDs), outlining their four mathematical symbols and demonstrating a Level-0 Context Diagram and a detailed Level-1 DFD for a complex College Registration System.
