Point-to-Point Protocol.
CUPS supports IPP, LPD/LPR, HTTP, SMB, and JetDirect (socket) protocols.
IP- Multi-Service Access Node. It supports a lot more protocols than a regular DSLAM, but only supports one output protocol, IP.
Yes. Three examples are:HTTP - HyperText Transfer Protocol (used to transfer web pages)FTP - File Transfer Protocol (as it says)SMTP - Simple Mail Transfer Protocol (supports some functions of the email system)These are all service layer protocols. Underpinning these are transport layer protocols, principallyTCP - Transport Control Protocol (used for most services)UDP - User Datagram Protocol (used for services and internal internet mechanisms that favor unimpeded delivery over assurance, order, and/or control of data flow)There are layers of protocol below this; the immediate one is the internetwork layer, which allows the higher layers to work seamlessly over multiple interconnected network media such as WiFi, Ethernet, optical fiber, etc. Below that are the protocols that correspond to the specific media.
OSPF is a classless link-state routing protocol. RIP version 1 and IGRP are both classful distance vector routing protocols, EIGRP is a hybrid protocol that supports classless addressing.
Dovecot supports IMAP & POP3 protocols.
protocol, Actually Protocol handles the address part of each packet so that it gets to the right destination. The right answer is (HTTP) Hypertext Transfer Protocol.
Ubuntu includes Pidgin, a multi-protocol chat client. It supports Yahoo!, MSN, AIM, Jabber and GMail, ICQ, and MySpaceIM. If you choose, you can also install Kopete, which supports a similar number of protocols, as well as video / webcam support.
The Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite, often simply referred to as TCP/IP. Using TCP, applications on networked hosts can create connections to one another, over which they can exchange streams of data using Stream Sockets. The protocol guarantees reliable and in-order delivery of data from sender to receiver. TCP also distinguishes data for multiple connections by concurrent applications (e.g., Web server and e-mail server) running on the same host. TCP supports many of the Internet's most popular application protocols and resulting applications, including the World Wide Web, e-mail, File Transfer Protocol and Secure Shell. Taken from WikiPedia
HyperText Transfer Protocol, commonly known as http.
Winsock provides simultaneous access to multiple transport protocols. Winsock is version-agnostic and supports multiple versions of a transport protocol, such as TCP/IPv4 and TCP/IPv6. Winsock defines a standard service provider interface (SPI) between Ws2.dll and the protocol stacks. In this way, a single Ws2.dll can simultaneously access multiple stacks from different vendors. Because a single Ws2.dll must work across all stacks, you do not need to supply your own implementation of Ws2.dll. A transport protocol must be properly installed on the system and registered with Winsock to be accessible to an application. Ws2.dll exports a set of functions that facilitate the registration process enabling you to create a new provider and remove an existing one. When registering, your installation script must supply one or more completed WSAPROTOCOL_INFO structures containing a complete set of information about the protocol. Any transport stack installed in this manner is referred to as a "Winsock service provider". For more information about how to install a transport stack, see Winsock Service Provider Interface (SPI).
Yes, through additional network protocols. The support may not be as solid as TCP/IP however.
Pidgin software was formerly called Gaim. Pidgin is an open-source instant messaging client. Pidgin is based on a library called libpurple. Libpurple supports multiple instant-messaging protocols.
