A client-server network is

[a] network that dedicates certain computers called servers to act as service providers to computers called clients.[1]


"In a client-server network, one or more central computers (called "servers") store the information; upon request from a user (or "client"), the server sends the requested information to the client. In other words, the server supplies information resources to clients, but the clients do not share any of their resources with the server. Client-server networks tend to be relatively secure, but they have a few drawbacks: if the server goes down, the entire network fails; and if many clients make requests at the same time, the server can become overwhelmed, increasing the time it takes the server to fulfill requests from clients. Client-server systems, moreover, tend to be more expensive to set up and operate than other systems. Websites work on a client-server model, with the server storing the website's content and delivering it to users upon demand."[2]
