In the world of computers, networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software. A network can consist of two computers connected together on a desk or it can consist of many smaller network connected together to form a bigger network across a continent.

Two-Tier Networks In a two-tier network, a client communicates directly with a server. This is also known as a client-server architecture. A client-server network is an architecture that involves client processes that request services from server processes. The client and server communicate over a network using a given protocol, which must be installed on both the client and the server. A common error in client-server network development is to prototype an application in a small, two-tier environment and then scale up by adding more users to the server.
