Which of the following typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet?
A. Thin client
B. Cloud computing
C. Application Virtualization
D. Terminal services
Answer: B
Explanation:
Cloud computing typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet. It provides common business applications online that are accessed from a web browser, while the software and data are stored on the servers. Answer option A is incorrect. A thin client is a low-cost computer, often legacy desktops, with limited resources. Thin clients run the latest operating systems (Windows 2000 Server and Windows Server 2003) and applications through special software such as the Terminal Services application. There is no requirement to install and configure applications on each computer, as the software are installed and configured in a centralized location on the server. Hence, the maintenance tasks are centralized. Answer option D is incorrect. Terminal Services is a multisession environment that provides remote computers access to Windows-based programs running on a server. When a user runs a program on a Terminal Server, the application execution takes place on the server, and only the keyboard, mouse and display information are transmitted over the network. Each user sees only his individual session, which is managed transparently by the server operating system, and is independent of any other client session. Answer option C is incorrect. Application virtualization is an umbrella term that describes software technologies that improve portability, manageability and compatibility of applications by encapsulating them from the underlying operating system on which they are executed.

You need to select a laptop for a traveling salesman. He will really need to stretch the battery life as long as possible, so he wants low power options wherever possible. Which type of monitor should you select?
A. LCD
B. CRT
C. Active Matrix
D. Passive Matrix
Answer: D
Explanation:
Passive matrix LCD monitors use less power than active matrix, and are generally preferred for laptops when long battery life is the key concern. Answer option C is incorrect. An active matrix LCD uses more power than a passive matrix, but gives a higher quality picture. Answer option B is incorrect. Cathode Ray Tube monitors are legacy monitors that were once used on PC's. Answer option A is incorrect. All laptops use LCD monitors. The question is whether or not one should select an active or passive matrix LCD. What is Cathode Ray Tube (CRT)? Hide Cathode Ray Tube (CRT) is a vacuum tube used as a display screen in a computer monitor or TV. The viewing end of the tube is coated with phosphors, which emit light when struck by electrons. CRT works by heating a cathode which causes electrons to flow. Accelerating and focusing anodes turn the electrons into a fine beam that is directed to the phosphors by magnetic fields that are generated by steering coils. The viewing end of a color CRT tube is coated with red, green and blue phosphor dots, and separate "electron guns" bombard their respective colors a line at a time in a prescribed sequence. The resulting color displayed on screen is determined by the intensity of the electron beams as they strike the red, green and blue phosphors at that same pixel location.
