Introduction:

In the realm of computing, communication plays a pivotal role in connecting entities and enabling seamless information exchange. In the context of distributed systems, where computers collaborate through networked communication, the significance of networks cannot be overstated. Networks serve as the vital medium for transmitting messages and facilitating coordination among the nodes that form a distributed system. Without a network, the very foundation of a distributed system crumbles, resulting in a loss of communication, coordination, and the entire essence of a distributed architecture.

1. Dependency on Networks:

The Crucial Backbone of Distributed Systems

At the core of any distributed system lies the dependency on networks. These intricate webs of connectivity present their own set of challenges and adversities that directly impact communication and coordination among the system's computers. The absence of a reliable network would render a distributed system futile, as it would strip away the fundamental elements necessary for communication and coordination among nodes.

2. Elevated Program Complexity:
