OLE,COM and ActiveX
Posted by kiraninbng on September 8, 2006
First came OLE(Object linking and embedding) , which was basically used in ms applications to embed an object of one into another.
Then came the COM standard which took over the tasks of the OLE.For sometime it was also called as OLE2 for sometime.
Next was the ActiveX,which referred to suite of COM based technologies targeted mainly at the internet.The best known ActiveX technology are ActiveX controls.
Then came DCOM which is basically use of COM across the networks.
I guess now the .NET technologies are replacing the COM based technologies and are much simpler.
