The client-server model
The client-server reference models demonstrated a standard way for data to communicate between two nodes. Of course, by now, we all know that not all nodes are created equal. Even in the earliest Advanced Research Projects Agency Network (ARPANET) days, there were workstation nodes, and there were server nodes with the purpose of providing content to other workstation nodes.
These server nodes typically have higher hardware specifications and are managed more closely by engineers. Since these nodes provide resources and services to others, they are appropriately referred to as servers. Servers typically sit idle, waiting for clients to initiate requests for their resources. This model of distributed resources that are requested by the client request is referred to as the client-server model.
Why is this important? If you think about it for a minute, the importance of networking is greatly highlighted by this client-server model. Without the need to...
