Q144. - (Topic 3) 

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. SSID 

B. ActiveX 

C. Cookies 

D. JavaScript 

Answer: 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.

A. Wear silken clothes. 

B. Do not wear wrist strap. 

C. Remove carpets from computer rooms. 

D. Wear cotton clothes. 

E. Increase humidity level. 

Answer: C,D,E 

Explanation: 

In order to reduce the chances of static charges being built up, users or technicians will have to take the following steps: 

Wear cotton clothes. This will reduce the chance of building up of static charges. 

Do not cover the computer room's floor with carpets. This stops neutralizing of static charges. 

Increase humidity level. Humidity helps dissipate static charges. 

What is ESD? 

ESD stands for Electrostatic discharge. The static electricity that we generate everyday creates ESD. If you walk across a carpet and touch someone, you experience a mild shock. Electrostatic discharge occurs when the electrostatic charge is transferred from one charged entity to another entity sensitive to that charge. 

To minimize Electrostatic discharge (ESD) problems, consider wearing a wrist strap when you are working with computer components. A wrist strap is a wire with a watchband-style strap at one end and a plug or clip on the other end. The wrist strap plug or clip is connected to the ground or to the piece of equipment being worked on. 

Answer option A is incorrect. A technician should not wear silken clothes during computer servicing, as silken clothes are more likely to generate static charges than cotton clothes. 

Answer option B is incorrect. Wearing wrist strap will keep a technician grounded. Hence, static charges cannot build up.
