Why Internet is a client-server technology?

Functions such as exchanging e-mail, Internet access and database access, are built based on client-server model. For example, a web browser is a client program running on a user’s computer that can access information stored on a web server on the Internet.

Clients and servers communicate with each other across the Internet or any other network. (Client-server applications are also common on local area networks). The client requests some service and the server performs it (or returns an error message if there is a problem). The Web is a familiar client-server application.

In computing, a client is a piece of computer hardware or software that accesses a service made available by a server as part of the client–server model of computer networks. The server is often (but not always) on another computer system, in which case the client accesses the service by way of a network.

The client relies on sending a request to another program in order to access a service made available by a server. The server runs one or more programs that share resources with and distribute work among clients. Popular client-server applications include email, the World Wide Web, and network printing.

3. Client-Server Network: advantages and disadvantages

A thin client is a computer that runs from resources stored on a central server instead of a localized hard drive. Thin clients work by connecting remotely to a server-based computing environment where most applications, sensitive data, and memory, are stored.

Some familiar examples of a client server system on the internet are file transfer protocol clients (FTPs), Web servers, Web browsers and DNS. The network clients like the ones mentioned above, send requests to the server by sending messages.

Disadvantages of Client Server Computing If all the clients simultaneously request data from the server, it may get overloaded. This may lead to congestion in the network. If the server fails for any reason, then none of the requests of the clients can be fulfilled. This leads of failure of the client server network.

All of the machines on the Internet are either servers or clients. The machines that provide services to other machines are servers. And the machines that are used to connect to those services are clients. There are Web servers, e-mail servers, FTP servers and so on serving the needs of Internet users all over the world.

The client uses the network as a way to connect with and speak to the server. Just as the customer speaks to his server, the client uses the network to send and receive communications about its order, or request. The server will take the request and make sure that the request is valid.

Try again to connect the client computer to the server. For instructions, see Connect computers to the server. If you still cannot connect the client computer to the server, make sure that the date and time on the server are correct. If the date and time are not correct, change them.

A client computer typically communicates only with servers, not with other clients. A client system is a standard PC that is running an OS such as Windows. Current OSes contain client software that enables the client computers to access the resources that servers share.
