Which of the following is a framework for defining reusable software components that perform a
particular function or a set of functions in Microsoft Windows?
A.
ActiveX
B.
Cookies
C.
JavaScript
D.
SSID
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 C 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 D 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 B 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.
