The document discusses ActiveX, a technology developed by Microsoft that allows web pages to run scripts and other small programs. It provides a brief history of ActiveX, noting it was Microsoft's response to Sun Microsystems' Java technology. The document also mentions how ActiveX is supported by Internet Explorer but not other browsers, and that it can potentially be used for Distributed Denial of Service (DDoS) attacks if not properly secured. It concludes by asking if ActiveX is still relevant given newer web technologies like HTML5.
