You have enabled the GPS service in your tablet. What is the minimum number of GPS satellites your tablet needs to be in contact with to determine its location?
Two
Three
Four
Three
GPS systems were designed to require multiple satellites. Receivers use a process called triangulation, which they use to calculate the distance between themselves and the satellites (based on the time it takes to receive a signal) to determine their location. They require input from four satellites to provide location and elevation or three to provide location
You are investigating new laptops for your company. You want the laptop displays to have a wide viewing angle. Which technology is best suited for your needs?
LED
IPS
TN
IPS
There are two types of LCD technologies listed in the exam objectives: TN and IPS. Twisted nematic (TN) is the older of the two, and it is relatively inexpensive and low power. The issue with TN LCD screens is that when you start viewing them at wider angles, the picture quality suffers greatly. In-Plane Switching (IPS) LCD monitors provide better color representation as well as wider-angle viewing, but they tend to be a bit more expensive and have somewhat slower response times
You are using a USB flash drive to transfer files from a laptop. You plug the USB drive in and then copy the files to it. What is the recommended way to remove the drive?

The new model of laptop just purchased by your company has a Universal ExpressCard slot. Which of the following types of cards can you install into that slot?
ExpressCard/54 only
ExpressCard/34 and ExpressCard/54
ExpressCard/24, ExpressCard/34, and ExpressCard/54
ExpressCard/34 and ExpressCard/54
A Universal ExpressCard host slot is wide enough to fit either an ExpressCard/54 or an ExpressCard/34 adapter; both of them have 26-pin connectors. (Slots designed for an ExpressCard/34 device cannot accommodate its wider cousins.) Universal ExpressCard slots also appear to be able to accept a CardBus adapter, but the card inserts not even an inch before stopping on the internal guide that ensures correct ExpressCard/34 insertion. ExpressCards can also be used to facilitate wireless and cellular connections
