MCS-218 IGNOU Solved Assignment 2026-27

Course Scope and Syllabus Overview for MCS-218: Data Communication and Computer Networks

MCS-218: Data Communication and Computer Networks is a core component of the Master of Computer Applications (MCA)-New curriculum under IGNOU’s School of Computer and Information Sciences (SOCIS). This course provides a rigorous foundation in the principles of data transmission, networking protocols, and the architectural frameworks that underpin modern computer networks. Students explore critical concepts such as signal encoding, error detection, network topologies, and layered communication models while aligning with the CBCS framework. The syllabus is designed to equip learners with both theoretical insights and practical skills to analyze, design, and troubleshoot communication systems, ensuring relevance to contemporary IT infrastructure demands.

Key Syllabus Units and Topics

• Block-1 Introduction to Data Communication: Covers fundamental concepts including data transmission techniques, analog/digital signals, modulation methods, and the role of communication channels in network design.
• Block-2 Media Access Control and Data Link Layer: Examines protocols for managing shared media access (e.g., CSMA/CD, token passing), error control mechanisms, and the structure of data link layer services.
• Block-3 Network Layer: Focuses on routing algorithms, IP addressing, subnetting, and the hierarchical architecture of the Internet, including IPv4/IPv6 transitions and network layer protocols.
• Block-4 Transport Layer and Application Layer Services: Analyzes transport protocols (TCP/UDP), connection establishment, congestion control, and application-layer services like DNS, HTTP, and FTP.
