QUESTION 

Which of the following will allow you to use a laptop as a desktop system? (Select two)

A. External Hard drive

B. Port Replicator

C. Hot Swappable drive

D. Docking station

E. Home base

Answer: B, D

B: A Port Replicator is a device containing common PC ports, such as serial and parallel ports, that plugs into a notebook computer. The purpose of the device is to allow you to easily attach a portable computer to standard, non-portable devices such as a printer and monitor.

For example, if you use a computer at home and at work, you can set both work areas with port replication. After that, you simply plug in your notebook computer for port replication at any location and you're ready to work. Most notebook computer manufacturers offer port replication as an additional option.

A port replicator is similar to a docking station, but docking stations provide expansion boards and additional slots for connecting storage devices.

D: A docking station is a platform in which you can install a portable computer. Docking stations usually have slots for expansion cards, bays for storage devices, and connectors for peripheral devices such as printers, keyboards, and monitors.

 After inserting it into the docking station, the portable computer essentially becomes a desktop model computer. When it is taken out, it again becomes a portable computer. Most importantly, the same data is accessible in both modes because it resides on the portable computer's drives.

The idea behind docking stations is to let you enjoy the expansion possibilities of desktop model computers together with the portability of notebook computers. In addition, the docking station enables you to use and monitor full-size keyboards when you are not traveling.

Incorrect Answers

A: Not required.

C: Not required.

E: There is no such thing in this context.

QUESTION

Which of the following should be placed between a heatsink and a processor setting them in place?

A: Thermal grease.

B: Rubber cement.

C: Plastic plate.

D: Ceramic plate.

Answer: A

Tiny (invisible) gaps between the two. Since air conducts heat poorly, these gaps have a very negative effect on the heat transfer. Therefore, an interface material with high thermal conductivity is needed to fill these gaps, and thus improve heat conductivity. The most commonly used interface material in the electronics cooling area is thermal compound, a sticky paste applied directly on the heatsink or CPU. A good-quality thermal compound will provide the best possible performance.
