BCA Semester 6 Question Papers 2025–2026 – Gurugram University (GU) & MDU

E-Commerce BCA Semester 6 covers online business models and the technologies behind secure digital transactions. Key topics include: E-Commerce models (B2B – Business to Business, B2C – Business to Consumer, C2C – Consumer to Consumer, C2B – Consumer to Business), Electronic Payment Systems (credit/debit card payment, Electronic Fund Transfer (EFT), digital wallets, digital cash, smart cards), E-Commerce Security (SSL – Secure Socket Layer, TLS – Transport Layer Security, digital signatures, public key infrastructure, firewalls, encryption), EDI (Electronic Data Interchange) and its role in B2B transactions, Supply Chain Management in e-commerce, Digital Marketing (SEO, SEM, email marketing, social media marketing), E-Commerce website design principles, and Legal and ethical issues (data privacy, cyber laws, consumer protection). Mastering these concepts prepares you for building secure online platforms and understanding how companies like Amazon, Flipkart, and Shopify operate their digital businesses.

Object Technologies & Programming Using Java BCA Semester 6 covers enterprise-level Java development with a strong OOP foundation. Topics include: Object-Oriented Programming in Java (classes and objects, constructors, method overloading, single and multilevel inheritance, method overriding, interfaces, abstract classes), Exception Handling (try-catch-finally, throw and throws, custom exceptions, checked vs unchecked exceptions), Multithreading (Thread class, Runnable interface, thread lifecycle, synchronization, inter-thread communication), Java Collections Framework (List – ArrayList, LinkedList; Map – HashMap, TreeMap; Set – HashSet, TreeSet; Iterator and ListIterator), File I/O (FileInputStream, FileOutputStream, BufferedReader, FileWriter), JDBC (database connectivity, PreparedStatement, ResultSet, CRUD operations), Servlets (HTTP Servlet, doGet, doPost, session management, cookies), JSP (JavaServer Pages), and Applets. Java's platform independence and widespread enterprise adoption make it one of the most in-demand programming skills in the software industry.

The 2026 AI paper is the latest, shared by Shivam. Topics examined across these papers include: Introduction to AI (definition, characteristics of AI problems, AI vs traditional programming, AI applications – expert systems, robotics, game playing, computer vision), Production Systems (components, types, problem characteristics), Heuristic Search (generate-and-test, hill climbing – simple and steepest ascent, best first search, A* algorithm, AO* algorithm, constraint satisfaction problems, means-ends analysis), Knowledge Representation (propositional logic, predicate logic, computable predicates, semantic networks, frames and scripts, forward and backward chaining), Natural Language Processing (NLP) (syntactic processing, context-free grammar, semantic analysis, discourse analysis, pragmatic analysis), Machine Learning (supervised learning – decision trees, naive Bayes; unsupervised learning – clustering; reinforcement learning), Neural Networks (perceptron, multilayer neural networks, backpropagation), and AI Learning Methods (rote learning, inductive learning, explanation-based learning).

Introduction to .NET BCA Semester 6 covers the Microsoft .NET framework and C# programming for Windows and web application development. Topics include: .NET Framework Architecture (CLR – Common Language Runtime, CTS – Common Type System, CLS – Common Language Specification, .NET class library, JIT compilation), C# Programming (data types, variables, control structures, arrays, strings, OOP in C# – classes, inheritance, polymorphism, interfaces, abstract classes), Advanced C# Features (delegates and events, generics, LINQ – Language Integrated Query, lambda expressions, anonymous methods, nullable types), Windows Forms Development (Form controls – TextBox, Label, Button, ListBox, ComboBox, CheckBox, RadioButton, Timer; event handling in Windows Forms), ASP.NET Web Development (web forms, server controls, state management – ViewState, Session, Cookies; master pages, GridView, DataList), ADO.NET Database Connectivity (Connection, Command, DataReader, DataAdapter, DataSet, CRUD operations with SQL Server), and Exception Handling in C# (try-catch-finally, custom exceptions). .NET enables rapid development of Windows applications, web services, and enterprise solutions widely deployed in corporate environments.
