7. Why ActiveX ?  The World Wide Web contain islands of code.  ActiveX bridge the gap.  Based on the following user’s interest: Software developer - want ease of creation, reuse and integrate software components.

8. ActiveX and Java  Downloaded ActiveX controls are saved to the hard drive while Java applets are not cached.  Java applets cannot interact with a user's machine outside of a specified “sandbox”.  While ActiveX offer more functionality with open interaction, it’s also more vulnerable to malicious code.

9. Security Issue  With the powerful functionality, ActiveX can be programmed to do virtually anything once downloaded.  Used the honor system called Authenticode.
