Question 18

Which of the following is a standard computer that can access resources locally as well as from servers but requires no specialized enhancements?

a) Gaming PC
b) Network-attached storage
c) Thin client
d) Thick client

Answer 18

D. Thick client

A thick client is any computer system with a standard configuration. The gaming PC has enhancements over thick clients to their CPU, video, audio, and cooling. The NAS (network-attached storage) must have specialized capabilities and services along with a faster NIC than the thick client and a RAID array. The thin client is a lesser device in comparison to the thick client, but that cost-saving feature is its enhancement. These less expensive computers can connect over the network to servers for their operating system images and applications. See Chapter 4 for more information.

Question 19

What is the function of the laser in a laser printer?

a) It heats up the toner so that it adheres to the page.
b) It charges the paper so that it will attract toner.
c) It creates an image of the page on the drum.
d) It cleans the drum before a page is printed.

Answer 19

C. It creates an image of the page on the drum.
The laser creates an image on the photosensitive drum that is then transferred to the paper by the transfer corona. The fuser heats up the toner so that it adheres to the page. The transfer corona charges the page, and the eraser lamp cleans the drum before a page is printed. A rubber blade is also used to remove toner physically from the drum. See Chapter 5 for more information.

Question 20

The ____________ is the measurement of the number of pixels an LCD monitor can display without the image appearing distorted.

a) Native resolution
b) Contrast ratio
c) Maximum resolution
d) Aspect ratio

Answer 20

A. Native resolution

The native resolution refers to how many pixels an LCD screen can display (across and down) without distortion. The native resolution is based on the placement of the actual transistors that create the image by twisting the liquid crystals. The contrast ratio is the measurement between the darkest color and the lightest color that an LCD screen can display. Monitors do not measure contrast ratio. Aspect ratio measures the width of the image versus its height.
