There is no single protocol used between a server and a client; the protocol depends on what the server and client are doing and how they are currently communicating.
POP (Post Office Protocol) - The protocol that an e-mail server and client usewhen the client requests the downloading of e-mailmessages.
An efficient request-reply protocol for a client-server communication and data processing model. Under the novel protocol, a client sends a Request to a server and awaits a Reply. If the Reply is not sent before expiration of a timeout period in the client, the client sends a second Request. The server provides a conditional Acknowledge if a second Request is received from the client. Thereafter, the client waits for the server to transmit a Reply without the client sending additional Requests. Under normal conditions, the inventive protocol performs as well as the best prior art protocol (the optimistic model), while under abnormal conditions, the inventive protocol performs better than the optimistic protocol and only slightly worse than the prior art pessimistic protocol. Since normal conditions should prevail for a substantially longer amount of time than abnormal conditions, the present invention provides better average performance than either prior art client-server protocol.
A single computer can function as both a client and a server, but performance will be degraded.
The File Transfer Protocol is a standard network protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client-server model architecture using separate control and data connections between the client and the server
Remote Desktop Protocol
In order to test a client server application, you need to know the following parameters:1) First of all, you need to know the number of users who work on the application on an average.2) you also need to know the peak load i.e. how many users at the max?3) Bandwidth of the network connection.4) Which action is most frequently done by the users.etc.All these parameters can be used to emulate the real scenario in run-time settings/controller.Various scenarios can also be created in Controller to emulate the real-time scenarios.ÂSubmitted by: Meet Kamal Kaur
A client cannot see what a server is doing; the only thing that can be monitored by the client is the data communication between the client and the server. If the client needs to see what is going on in the server then the client needs to connect to the server using remote desktop protocol, Terminal Services, telnet, or some other way to directly connect to the server.
A File Transfer Protocol works on a client-server architecture and uses separate control and data connections between the server and the client. FTPs are used in businesses and government agencies world-wide.
SMTP is push protocol, stateful protocol which is used for sending Mails from Client to Client or Server to Server. Generally SMTP uses the encryption method of 7bit or 8bit ISCII but HTTP dose not use that. HTTP is pull protocol which is preferred for sites demand and this is stateless protocol.
The server knows by the destination port number, which attaches a listening program to a specific protocol.
Chap (Challenge Handshake Authentication Protocol)
