LED
Smaller devices, such as tablets and phones, almost exclusively use LED backlighting, which is smaller and consumes less power than CCFLs
You are purchasing a mobile device that allows you to use your finger to input information. What type of touch screen technology does this device use?
Capacitive
Human based
Resistive
Capacitive
Capacitive touch screens are a little less accurate than resistive touch screens but more responsive. They respond to changes in electrical current, and as such, the human fingertip works great as the facilitator of input
You are using a public Wi-Fi hotspot and believe that someone is trying to hack into your laptop. Which laptop feature should you use to immediately turn off all wireless connections?
Silent mode
Quiet mode
Airplane mode

A user approaches you and asks for a CPU upgrade so his Lenovo laptop will run faster. What is most likely the easiest way to meet this user’s needs?
Replace the laptop with one with a faster CPU
Replace the motherboard with a standard laptop motherboard with a faster processor
Replace the motherboard with a Lenovo laptop motherboard with a faster processor
Replace the laptop with one with a faster CPU
Laptop processors generally are permanently attached to the motherboard. And motherboards are normally proprietary, meaning one from a certain model will not fit into a different case. Therefore, the best course of action is likely a laptop upgrade
You are using a laptop computer and the wireless network card fails. There are no wired ports nearby. You need to send a file to your boss, who is in another country, in the next 10 minutes. What should you do to fix this situation?
Install a USB to RJ-45 dongle
Install a USB to Wi-Fi dongle
Install a USB to Bluetooth dongle
Install a USB to Wi-Fi dongle
A USB to Wi-Fi dongle will allow your computer to use that wireless network connection to get back up and running. Once you are on the network again, you can send the file. Replacing a network card on a laptop generally means replacing the entire motherboard. You can also get USB to Ethernet adapters for wired networking
Which type of mobile device is known for using electrophoretic ink?
E-reader
Smart glasses
Tablet
E-reader
Most e-readers use a technology called electrophoretic ink, or E Ink, which is a proprietary type of electronic paper. Although E Ink is available in colour, many consider its best applications to be in grayscales or pure black and white. Additionally, E Ink uses almost no power to keep print on the page until the print is changed
What type of connection are you using if you use a USB cable to connect your laptop to your cellular phone in order to use the cellular wireless connection from the laptop?
Hotspot
Tethering
Phoning
Tethering
Tethering is connecting a device to a mobile hotspot. The term used to be reserved only for when you were connected via USB cable, as opposed to connecting via wireless. Some devices will not function as a mobile hotspot but will allow you to tether a mobile device to it with a USB cable so the mobile device can share the cellular Internet connection

The hard drive in your manager’s desktop has failed, and you need to replace it. Your manager asks about the benefits of replacing it with an SSD instead of an HDD. What should you tell her? (Choose two)
They are cheaper
They take up less space
They consume less power and generate less heat
They operate silently
They consume less power and generate less heat
They operate silently
SSDs have several advantages over magnetic HDDs. They include faster startup and read times, less power consumption, silent operation, and higher reliability because of lack of moving parts, and they are less susceptible to damage from physical shock and heat production
Which laptop expansion port was designed as an industry standard to replace VGA and DVI ports and is backward compatible with both standards?
Displayport
Videoport
Thunderbolt
Displayport
The Video Electronics Standards Association (VESA) introduced DisplayPort in 2008. It was designed to be an industry standard and to replace VGA and DVI. It’s also backward compatible with VGA and DVI by using adapters. A display port is intended to be for video devices only, but like HDMI and USB, it can transmit audio and video simultaneously
In a laptop, which display type illuminates each pixel individually rather than by LED backlight?

He can choose a motherboard from any other laptop
He can choose a motherboard from any other Lenovo laptop
He must choose a motherboard from that same model of Lenovo laptop
He must choose a motherboard from that same model of Lenovo laptop
Laptop motherboards are nearly always proprietary, meaning they are not interchangeable between manufacturers or even between models from the same manufacturer. When a laptop motherboard needs to be replaced, you most likely need a laptop motherboard from the same make and model
A technician needs to replace a failed laptop hard drive. The user stores a large amount of video on her computer and needs the largest-capacity drive possible. What type of hard drive should you install?
Magnetic
Hybrid
Flash
Magnetic
Traditional magnetic hard drives will have greater capacity than SSD (which are a type of flash memory) or hybrid drives
