<h3>What is client-server network?</h3>
The client-server network idea can be used with either a LAN (local area network) or the Internet. Client-server networks commonly use DNS (Domain Name Systems), web browsers and servers, and FTP (file transfer protocol) clients.
Client-server networking is often employed in private networks used for corporate purposes, web services, and game hosting. In peer-to-peer networking, there is no central server. Instead, every computer on the network has the same capabilities and access rights.
The server receives the request, processes it, and sends the requested data packets back to the client computer when a client computer connects to it via the internet to request data. Clients do not share any of their resources.
