What is the protocol used by server and client?
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.
What is pop3?
POP3 is actually Post Office Protocol 3 which is an enhanced version of the standard protocol for receiving email. POP3 is a client/server protocol in which the email can be received. There are other protocols such as Internet Message Access Protocol(IMAP) Simple Mail Transfer Protocol (SMTP). if this answer is wrong,correct me..
Which protocol or protocol suite automatically allocates an IP address to a client on boot up?
The DHCP protocol.
What Protocol used to download email messages from an email server?
POP (Post Office Protocol) - The protocol that an e-mail server and client usewhen the client requests the downloading of e-mailmessages.
What are examples of a file transfer protocol?
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
What protocol is used for specialized network communications between a client and a terminal server?
Remote Desktop Protocol
What is IMAP?
Along with POP3, IMAP is one of two prevailing electronic mail protocols. IMAP is an acronym for Internet Message Access Protocol. It is is an Application Layer Internet protocol, meaning that it allows an e-mail client application to access electronic mail on a remote mail server. IMAP differs from the other prevailing e-mail protocol, POP3, in that the client's e-mail is retained in a set of private message directories on the IMAP mail server itself. This allows messages to be easily synchronized across multiple e-mail clients on multiple devices. POP3 protocol delivers messages to the client application for storage on the client device. Messages are subsequently deleted from the POP3 server, making synchronization of multiple devices more difficult. POP3 was the preferred e-mail protocol when server power and storage capacity were at a premium, and before the rise of ubiquitous Internet-enabled mobile devices. More recently, IMAP has supplanted POP3 as the most predominant e-mail protocol. All web-mail services (GMail, Yahoo Mail, Hotmail, etc.) are based on IMAP. Microsoft Exchange is also a form of IMAP. Today, nearly all Internet and private electronic mail servers support IMAP.
Describe the ways in which the request-reply protocol masks the heterogeneity of operating systems and of computer networks?
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.
What is the difference between direct message passing and indirect message passing?
În direct message passing communication, the endpoints (client and server) communicate via direct addressing. This means that the sender knows the exact address (ip for ex) of the receiver. In indirect communication, the link between the sender and the receiver is done via a port instead of direct addresses. The port acts as a mailbox for the messages and the sender doesn't need to know the exact ip of the receiver. The sender simply sends the message via a port and the receiver collects the message from that port. This way of communicating has several advantages over the direct way (for example it allows multipoint and multipath communication)
What is the difference between HTTP and SMTP?
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.
What application layer protocol is commonly used to support for file transfers between a client and a server?
File Transfer Protocol
What application layer protocol is commonly used to support for file transfers between a client and a serve?
FTP (File Transfer Protocol).
