Common Object Request Broker Architecture (CORBA) is a way of connecting different kinds of computers and software together so that they can all talk to each other. It makes it easy for programs on different kinds of computers to send messages and share data. It does this by having a "broker" that acts like a middleman. It connects the programs, and helps them exchange data. CORBA also has special standards so that all of the programs using CORBA understand what kind of messages they need to send and what information they need to get back.
