Interconnection refers to the process of connecting different computer systems or networks to enable communication and data exchange. This can involve physical connections through cables, routers, and switches, as well as virtual connections using protocols and software. Interconnection plays a crucial role in the functioning of the internet, as well as in data centers, telecommunications networks, and other interconnected systems. Research in this area focuses on improving the efficiency, reliability, security, and scalability of interconnections to meet the growing demands of modern technology. This includes studying network protocols, designing new hardware and software solutions, and exploring new technologies such as cloud computing and software-defined networking.
