The bezel is the case in which the LCD screen is set, and typically houses the antenna for wireless network cards.

Which of the following battery types offers the greatest storage capacity in the smallest amount of space? - Nickel Cadmium (Ni-Cad) - Nickel Metal Hydride (NiMH) - Carbon - Lithium Ion (Li-Ion)

Lithium Ion (Li-Ion) Explanation Lithium Ion (Li-Ion) batteries offer the greatest storage capacity in the smallest amount of space. Nickel Cadmium (Ni-Cad) and Nickel Metal Hydride (NiMH) batteries take up more physical space than Lithium Ion batteries. Carbon batteries are small, but have significantly less charge than Lithium Ion batteries. They are commonly used in remote controls, flashlights, toys, or transistor radios, where the power drain is not too heavy.

Laptop memory uses SODIMM and UniDIMM packages with SDRAM and DDR/DDR2/DDR3/DDR4 memory. What are these modules sometimes called? - TinyDIMMs - MiniDIMMs - MacroDIMMs - MicroDIMMs

Which type of interface is typically used for internal wireless networking cards in laptops? - Firewire - PCI - Mini-PCI - USB - ExpressCard

Mini-PCI Explanation Most internal wireless network cards in laptops connect using a mini-PCI interface. USB, Firewire, and ExpressCard are external buses for external devices.

Which of the following battery types has the greatest need to be completely drained before being recharged? - Nickel Metal Hydride (NiMH) - Nickel Cadmium (Ni-Cad) - Carbon - Lithium Ion (Li-Ion)

Nickel Cadmium (Ni-Cad) Explanation Nickel Cadmium (Ni-Cad) batteries experience a memory effect. If the battery is not completely drained before being recharged, the remaining charge in the battery eventually becomes unusable. Draining the battery completely on occasion ensures that the battery can access its full capacity. Nickel Metal Hydride (NiMH) and Lithium Ion (Li-Ion) batteries do not have the memory effect and do not need to be completely drained. However, all batteries have a specific lifetime. After a period of time, the battery becomes less able to hold a charge and should be replaced.

Which of the following is an extra button or knob on a laptop keyboard that moves the mouse cursor? - Touch pad - Pointing stick - ExpressCard - Digitizer

Pointing stick Explanation Pointing sticks (also called a trackpoint) are small knobs in the center of the keyboard. Pushing on this knob moves the cursor. The touchpad is located below the keyboard. Moving your finger across the pad moves the mouse. You can also tap the touchpad to click the mouse. A digitizer pad is used in Tablet PCs to receive input. Input is written onto the pad with a stylus pen, then those motions are transferred into data that is processed by the system. An ExpressCard is an expansion card for laptops.

A user needs to use her laptop to give a presentation using a video projector. She called asking you how to switch the display to the external monitor port on her laptop. What should you tell her? - Press the Fn key along with the function key on the notebook keyboard with a monitor on it. - Increase the screen brightness until the display appears on the video projector. - The laptop should have automatically detected the external display and redirected video output to it. - This can't be done.
