AR 20 : B.Tech. IT III Year I Semester Data Communication and Computer Networks Subject Code: 20ITT301 L T P C 3 0 0 3 COURSE OBJECTIVES: Upon completing the course, the student will: Explain Data Communications System and its components, different types of network topologies and protocols. Demonstrate different layers of ISO and TCP/IP models and illuminate its function. Apply knowledge of different techniques of error detection and correction to detect and solve error bit during data transmission. Analyze main protocols such as HTTP, FTP, SMTP, TCP, UDP, IP. COURSE OUTCOMES: After completing this course, the student must be able to: 1. Identify and enumerate different types of network topologies, protocols and the layers of the OSI and TCP/IP models and explain the functions of each layer. 2. Analyze the features of Transmission media with various encoding techniques 3. Explain the protocols of Data Link Layer and MAC Sub layer and illustrate how a network can detect and correct transmission errors. 4. Classify, compare and analyze the major routing algorithms and distinguish congestion control algorithms and understand how a packet is routed over the internet. 5. Describe how TCP and UDP function, its uses and summarize the differences between them. 6. Analyze the features and operations of various Application layer protocols such as http, DNS, and SMTP.
