COM servers may be written with a different language and an entirely different operating system. COM objects have the capability of being

remotely accessible. That means they may be in a different thread, process, or even on a different computer. The other computer may even be

running under a different operating system. There needs to be a good way to transmit parameters over the network to objects on other

machines. This problem is solved by creating a new way to carefully specify the interface between the client and server. There is also a new

compiler called MIDL (Microsoft® Interface Definition Language). This compiler makes it possible to generically specify the interface between

the server and client. MIDL defines COM objects, interfaces, methods and parameters.
