How Does GPS Tracking Work? GPS tracking uses a network of satellites to determine the location of a device designed for that purpose. The basic idea is that a GPS tracker uses trilateration to determine its physical location based on its distance from three GPS satellites.

The difference between a GPS tracker and a car navigation system is that the navigation system provides you with your location and driving directions....

What Are Uninterruptible Power Supplies Used For? Most UPS should turn on almost instantly when a power disruption is detected, providing uninterrupted electrical power to the connected systems.

After all, a phone must fit into the user’s pocket and rest comfortably in the hand. So, to increase screen size, manufacturers must decrease the size of the bezel....

How Small is a Nanometer? Metric measurements are all based on the meter. Inspect any ruler or measuring tape, and you can see the numbered markings for meters, centimeters, and millimeters.
