Systems, Networks, and Digital Communication Technologies: A Comprehensive Review

Abstract

The blistering development of digital communication technologies has radically changed the nature of the functioning of systems and networks in the contemporary times. In this paper, the author develops an in-depth discussion of modern systems, network, and digital communication technologies, the shift towards 6G networks, the growth of Internet of Things (IoT) architecture, and integration of artificial intelligence and machine learning in network management, cybersecurity considerations, and paradigm shift towards Software-Defined Networking (SDN) and Network Functions Virtualization (NFV). The paper reveals critical trends in technology and recent research findings, its comparative performance indicators, and future research outcomes through systematic review of the recent literature and empirical studies. The results prove that the intersection of these technologies is offering unprecedented benefits to smart, dynamic, and secure communication systems and poses serious challenges in terms of scalability, energy consumption, and security that need to be overcome to implement it successfully.
