A big part of the internet resolves around the Client-Server Architecture. Now the question is what is the client and what is the server? Do you have such type of question? I know, you have. Lets talk about Client, Server and a wide architecture based on them called Client-Server Architecture.
In general sense, Client and Server is not any big thing but just two computer system. Yes, there is a vast difference in their functionality. Client is that computer system which sends requests for what it wants and the server is that computer system which responds such requests made by the client. Client and Server may communicate in computer network either on separate hardware or in a single machine. It means that client and server may be different computer system or may be the same. Server computer shares different resource to the client but client computer does not share with the other one but just makes a request to get the facility from the server. In short, Client - Server Architecture communicates in a request - response messaging pattern.
There is one more concept of Client Host and Server Host. There is some difference between host and client-server. Host is any computer which is connected to the Network. But the words clients and server represent any computer or computer program.
There are mainly three models of client server inter communication:
- Static HTML Pages
- CGI Scripts
- Server Side Scripting Technologies
