Third year opens with core systems and information-retrieval courses — Computer Networks, Operating Systems, and Information Retrieval Systems — while introducing the branch’s first Professional Elective and Open Elective choice points. Two lab courses reinforce networking and retrieval theory, and a Flutter-based UI design course plus a second full-stack development module build front-end and mobile skills. A community service project internship is evaluated this semester as well.
Subjects
Information Retrieval Systems
- Unit 1: Foundations of information storage and retrieval, including domain analysis of IR systems.
- Unit 2: Inverted files and signature files as core indexing structures.
- Unit 3: Advanced text indices, lexical analysis, and PAT trees/arrays.
- Unit 4: Stemming algorithms and thesaurus construction.
- Unit 5: String-searching algorithms, from naive matching through more efficient pattern-matching techniques.
L-T-P: 3-0-0, 3 credits
Computer Networks

Professional Elective-I options:
- Software Engineering — covers the evolution of software development practice, project-management complexities, the software design process, coding and testing strategies (including black-box testing), and CASE tools.
- Cloud Computing — covers cloud fundamentals, enabling technologies like virtualization and distributed computing, containerization, cloud economics and interoperability, and emerging serverless/FaaS models.
- Internet of Things — covers IoT technology and architecture, business models for connected devices, web-connectivity design principles, data acquisition and analytics, and cloud-based IoT data platforms.
- Exploratory Data Analysis with Python — covers EDA fundamentals, visual aids like line/bar/scatter charts, data transformation and merging, descriptive statistics, and end-to-end model development and evaluation.
- Automata Theory & Compiler Design — covers regular languages and finite automata, context-free grammars and pushdown automata, lexical analysis and top-down parsing, bottom-up parsing, and intermediate code generation/optimization.
L-T-P: 3-0-0, 3 credits (one option selected)
Open Elective-I is filled either from the cross-department open elective pool (each engineering branch offers a course, commonly foundational subjects like Operating Systems or Database Management Systems, to other departments’ students) or by choosing the in-house alternative, Entrepreneurship Development & Venture Creation.
Information Retrieval Lab
- Representing text documents in a vector-space model and computing inter-document similarity.
- Text preprocessing — stop-word removal and stemming.
- Building an inverted index over a moderately sized document collection.
- Classifying and clustering text documents, and evaluating results with standard metrics.
- Web crawling, topic-specific PageRank computation, matrix decomposition/LSI, and social-media text mining.
L-T-P: 0-0-3, 1.5 credits
Computer Networks Lab
- Setting up LAN devices and implementing data-link framing methods (character/bit stuffing, checksums).
- Implementing Hamming code and CRC-based error detection.
- Building sliding-window protocols (Go-Back-N, selective repeat) and the stop-and-wait protocol.
- Implementing congestion control (leaky bucket) and routing algorithms (Dijkstra’s, distance vector).
- Using Wireshark and Nmap for packet analysis and scanning, plus NS2-based network simulation.
L-T-P: 0-0-3, 1.5 credits
Full Stack Development-2
(Skill Enhancement Course; alternative: SWAYAM Plus Data Engineer/AI Engineer track)
- Express.js fundamentals — routing, HTTP methods, and middleware.
- Sessions, cookies, authentication, and building RESTful APIs in Express.js.
- React.js fundamentals — components, JSX, props, state, and styling.
- Conditional rendering, list rendering, forms, and client-side routing in React.
- React hooks and inter-component data sharing, paired with MongoDB CRUD operations.
L-T-P: 0-1-2, 2 credits
User Interface Design using Flutter
- Installing the Flutter/Dart toolchain and writing introductory Dart programs.
- Exploring core widgets and layout structures (Row, Column, Stack).
- Designing responsive UIs with media queries and breakpoints.
- Implementing navigation, state management, and custom themed widgets.
- Building forms with validation, adding animations, and consuming REST APIs within the UI.
L-T-P: 0-0-2, 1 credit
The Community Service Project Internship completed over the prior summer is formally evaluated this semester for 2 credits.
Semester total: 15-1-10 contact hours, 23 credits. Students may additionally opt into a Minor specialization course (3-0-3, 4.5 credits), a NPTEL/SWAYAM minor course (3 credits), or Honors-pool courses (3 credits each).
