Which form of mobile communication requires that devices be paired with one another? Bluetooth Infrared Near Field Communication (NFC) Wi-Fi
Bluetooth Bluetooth is a wireless radio protocol that allows devices within about a 30-foot range to communicate with each other. Bluetooth devices must be paired with one another before they can communicate. To accomplish this, devices must be put in discovery mode, in which they transmit their name to other devices that might be looking to pair with them. When two devices pair with each other, they use a secret key to establish a wireless connection. Previous
Which laptop function key enables you to connect wirelessly with other devices in a small area should a wireless local area network (WLAN) be unavailable? Cellular (On/Off) Pairing (On/Off) Bluetooth (On/Off) Location (On/Off)
Bluetooth (On/Off) The Bluetooth (On/Off) function key enables or disables Bluetooth, a wireless radio protocol that is used to communicate from one device to another in a small area, regardless of the availability of a wireless local area network (WLAN). The cellular function key enables or disables wireless wide area network (WWAN) access, which uses cellular networks to exchange data. There currently is no "Pairing" function key. Location (On/Off) function is likely not part of a laptop and is mostly used in mobile devices like smart phones and tablets. It uses global positioning systems to determine location the location of a device.
What is the purpose of the inverter in a laptop display?

How is internal storage handled in a tablet? A tablet has no internal storage A series of flash chips A very small hard drive A compact hard disk drive (HDD)/solid-state drive (SSD) hybrid
A series of flash chips The internal storage of a tablet computer is in the form of a series of chips that use flash memory. Because tablets are designed to be very slim and light, neither an HDD nor an SSD is a feasible solution. Tablets have limited internal storage, but this is easily expanded with additional storage in the form of cards such as micro Secure Digital (microSD) cards.

A smartphone
Which type of device is most likely to use a micro dual in-line memory module (MicroDIMM) module? A tablet A smartphone A sub-compact laptop A desktop
A sub-compact laptop A MicroDIMM module is used in smaller, sub-compact laptops. MicroDIMM modules are smaller than small outline dual in-line memory module (SODIMM) modules and measure about 1.5 inches in length. Smartphones and tablets typically have a small amount of internal flash memory, which is usually not upgradeable. However, most smartphones and tablets allow you to expand their storage capacities with Secure Digital (SD) and microSD cards. Desktop computers use larger, full-sized random-access memory (RAM) modules such as double data rate (DDR).

If the inverter on a laptop fails, what action should a hardware technician take to remedy the problem? Replace the laptop power supply Reinstall the operating system Reboot the laptop Replace the display
Replace the display The inverter converts direct current (DC) power to alternating current (AC) power for the display. In many cases it is advisable to replace the display rather than just the inverter. Rebooting will not fix the problem. Reinstalling the operating system is impossible since the display is non-functional. Replacing the system's power supply will have no effect on the inverter.

Which laptop component uses a Thin Film Transistor (TFT)? Hard drive Motherboard Memory Screen
Screen Laptops use Thin Film Transistor (TFT) displays, which use either Twisted Nematic (TN) or In-Plane Switching (IPS) technology. TN has fast response times, high brightness, less power draw, and are inexpensive to manufacture in comparison to IPS. TN tends to have more color shift and distortion when viewed at an angle compared to IPS. IPS provides better color reproduction and better viewing angles. Originally, TN offered better contrast and better blacks than IPS, but newer IPS monitors have overcome these limitations.
