XML- RPC provides a fairly lightweight means by which one computer can execute a program on a co-operating machine across a network like the Internet. It is based on XML and is used for everything from fetching stock quotes to checking weather forcasts.
XMLRPC is a predecessor of SOAP. It's a spec and a set of implementations that allow software running on disparate operating systems, running in different environments to make procedure calls over the Internet. It's remote procedure calling using HTTP as the transport and XML as the encoding. XML-RPC is designed to be as simple as possible, while allowing complex data structures to be transmitted, processed and returned. See also SOAP. More at http://www.xmlrpc.com
XML Remote Procedure Call. A protocol for client-server communication that sends and receives information on top of HTTP. The data sent and received is in a particular XML format specifically designed for use with XMLRPC.
XML-RPC is a simple remote procedure call protocol encoded in XML. XML-RPC allows one computer to cause the execution of code on another machine. The advantage of encoding in XML is that XML is in itself plain text and understandable by almost all platforms.
XML-RPC is a remote procedure call protocol which uses XML to encode its calls and HTTP as a transport mechanism. It is a very simple protocol, defining only a handful of data types and commands, and the entire description can be printed on two pages of paper. This is in stark contrast to most RPC systems, where the standards documents often run into the thousands of pages and require considerable software support in order to be used.
