Data Communications and Networking Exam Bank
Course Introduction
Data Communications and Networking introduces the foundational principles and practical applications of data transmission and computer networking. The course covers essential topics such as network architectures, protocols, network devices, transmission media, and error detection techniques. Students will explore the OSI and TCP/IP models, gain hands-on experience with local area networks (LANs) and wide area networks (WANs), and understand the concepts behind switching, routing, and network security. By the end of the course, students will have a comprehensive understanding of how data is transmitted and managed across modern communication networks, preparing them for further study or careers in information technology and network administration.
