Programmatically, What is an RTD Server? Is it a Dedicated Computer That Serves Real-Time Data?
Basically an RTD server can be a dynamic-link library (DLL), an executable program (EXE) that is executed on your computer, or an EXE that runs on a separate computer. Technically, it is an Automation server that implements an extra interface called IRtdServer that communicates with Excel. So, a dedicated computer is not required, but a computer may be set aside just for the purpose of running instances of one or more RTD servers through DCOM.
