ActiveX control is software of Microsoft Windows operating system. It is a small program which is also referred to as addons used for internet.
Different ActiveX controls have different purposes and each of the ActiveX control program is stored in separate file which is given extension of OCX. These programs are integrated with Internet Explorer to enhance the user browsing experience.
