Sample Questions
Q1) Describe the differences between BIOS and UEFI firmware.
Answer: The older BIOS (basic input/output system) that contains system BIOS to manage essential devices (such as the keyboard, mouse, hard drive, and monitor) before the OS is launched, startup BIOS to start the computer, and BIOS setup to change the motherboard configuration or settings. Newer motherboards use Unified Extensible Firmware Interface (UEFI) firmware that is more robust and secure than BIOS. Just as with BIOS, UEFI is responsible for managing essential devices before the OS is launched, starting the computer, and managing motherboard settings. UEFI can also assure that the boot is secure and no rogue operating system hijacks the system.
Q2) Describe the Near Field Communication (NFC) technology.
Answer: Near Field Communication (NFC) is a wireless technology that establishes a communication link between two NFC devices that are within 4 inches of each other. For example, when you tap your smart phone with that of your friend, the two phones can use NFC to exchange contact information. NFC can also be used to read an NFC tag, which is a small microchip that can be embedded in just about anything, including a key chain tag, printed flyer, or billboard. The NFC tag dispenses information to any NFC-enabled smart phone or other device that comes within 4 inches of the tag.

A)True

Answer: True
Q2) How does working on and supporting a laptop differ from a desktop?
Answer: Laptops and their replacement parts cost more than desktop PCs with similar features because their components are designed to be more compact and stand up to travel. They use compact hard drives, small memory modules, and CPUs that require less power than regular components. Whereas a desktop computer is often assembled from parts made by a variety of manufacturers, laptop computers are almost always sold by a vendor that either manufactured the laptop or had it manufactured as a consolidated system. Factors to consider that generally apply more to laptop than desktop computers are the original equipment manufacturer's warranty, the service manuals and diagnostic software provided by the manufacturer, the customized installation of the OS that is unique to laptops, and the advantage of ordering replacement parts directly from the laptop manufacturer or other source authorized by the manufacturer.
