This can create issues with some devices connecting to the computer if they were designed to work with 32-bit machines, which were the previous standard.
A-GPS: Assisted GPS, generally abbreviated as A-GPS, is a cellular carrier network-dependent system which can, under certain conditions, improve the startup performance of a GPS satellite-based positioning system. The mapping process with A-GPS is generally very quick and efficient, but it is also dependent on cellular coverage. A-GPS is particularly useful in urban areas, when the user is located under heavy tree cover, or even indoors. This technology is becoming popular in cell phones and it’s commonly associated with Location Based Services. Popular smart phones like the iPhone, Palm Pre and BlackBerry Bold all use A-GPS.

This can be used to effectively dispatch trucks for delivery or emergency purposes. Fleet management software is either part of the GPS tracker’s capabilities or can be bought separately. Once vehicle location, direction and speed are determined from the GPS components, additional tracking capabilities transmit this information to a Fleet Management software application. Methods for data transmission include both terrestrial and satellite.

Passive GPS: Passive GPS devices store GPS location, speed, heading that can be quickly downloaded from the device onto your computer. The device is sometimes triggered by an event such as key on/off, door open/closed. Passive GPS is commonly used with fleet management and vehicle tracking where GPS data only needs to be harvested once in awhile rather than in real-time. Once the vehicle returns to a predetermined point, the device is removed and the data downloaded to a computer for evaluation. On the other hand, active GPS devices also collect the same information but usually transmit the data in real-time via cellular or satellite networks to a computer or data center for evaluation.
PTZ: PTZ refers to pan, tilt, and zoom. This is most often used on security cameras that sense motion or body heat and pan/tilt/zoom to capture the action.

They have largely replaced BNC connections on most home entertainment systems. It is used to connect everything from cameras to video game systems.
Real-Time GPS: Real-time GPS tracking systems send location updates to the Internet every 5 to 10 seconds. There is no need to retrieve the GPS device in order to get the location data, because you can view these real-time updates directly on the Internet. This let’s you follow a car or person to their approximate GPS location no matter where they are in real-time, online.
RF: RF refers to radio frequency, the mode of communication for wireless technologies of all kinds, and it is often used in baby monitors, remote control toys, cordless phones, radar, and GPS.
