The TMA includes 10 questions divided into two sectionsSection A (short-answer, 5 questions) and Section B (long-answer, 5 questions). Solutions incorporate real-world examples (e.g., TCP/IP in web browsing, Wi-Fi security protocols) and avoid generic textbook definitions. Diagrams for OSI model layers and TCP/IP stack are included in the PDF for visual clarity.
Subject-Specific FAQs
- QHow do I differentiate between connectionless (UDP) and connection-oriented (TCP) protocols in my answer?
Use a comparative table highlighting handshake process (TCP3-way, UDPnone), reliability (TCPacknowledgments, UDPnone), and use cases (TCPHTTP/HTTPS, UDPVoIP, live streaming).
- QAre there specific keywords IGNOU expects for network security answers?
Include terms like authentication protocols (802.1X), VPN tunneling (PPTP/L2TP), and encryption algorithms (AES-256) to align with Unit 4’s focus on security frameworks.
