B. ActiveX
C. Cookies
D. JavaScript
正解: B
Explanation:
ActiveX is a framework for defining reusable software components that perform a particular function
or a set of functions in Microsoft Windows. ActiveX controls are software components that can be
integrated into Web pages and applications, within a computer or among computers in a network, to
reuse the functionality. Reusability of controls reduces development time of applications and
improves program interfaces. They enhance the Web pages with formatting features and animation.
ActiveX controls can be used in applications written in different programming languages that
recognize Microsoft's Component Object Model (COM). These controls always run in a container.
ActiveX controls simplify and automate the authoring tasks, display data, and add functionality to
Web pages. Answer option D is incorrect. JavaScript is a simple, light weight, and dynamic World
Wide Web (WWW) scripting language developed by Netscape Communications. The syntax of
JavaScript resembles that of C++. JavaScript facilitates integration of HTML documents, Web
components, and multimedia plug-ins. It also aids in the development of server-side Web
applications. Answer option A is incorrect. SSID stands for Service Set Identifier. It is used to identify a
wireless network. SSIDs are case sensitive text strings and have a maximum length of 32 characters.
All wireless devices on a wireless network must have the same SSID in order to communicate with
each other. Answer option C is incorrect. A cookie is a small bit of text that accompanies requests and
pages as they move between Web servers and browsers. It contains information that is read by a
Web application, whenever a user visits a site. Cookies are stored in the memory or hard disk of client
computers. A Web site stores information, such as user preferences and settings in a cookie. This
information helps in providing customized services to users. There is absolutely no way a Web server
can access any private information about a user or his computer through cookies, unless a user
provides the information. A Web server cannot access cookies created by other Web servers.
