Commonly confused technology terms - GPS, GPRS & GIS what is the use and difference between these acronyms.

GPS (Global Positioning System)
A system of satellites around the Earth that broadcast the time via radio signals based on an internal atomic clock. GPS devices can receive the signals from multiple satellites, and by measuring the time it took the signal to arrive they can determine your current position on the Earth.

GPRS (General Packet Radio Service)
A mobile phone 2.5G technology that allows short bursts of data between a phone and a network such as the Internet. The short transmissions allow for less costly connectivity than a constant connection, but work best with specialized services designed for such types of communication.

GIS (Geographic Information System)
A system for capturing and manipulating data relating to the Earth. A common use of GIS is to overlay several types of maps (for example, train routes, elevation data, street maps) to determine useful data about a given geographic area.

Explain what does the acronym FPS stands for? What is its significance regarding display technology and computer gaming industry

Frames Per Second (FPS)
This term relates to video or 3D games, and is the amount of single full screen (or full window) pictures (or frames) that are displayed each second to generate what appears to be a moving image. Typical digital video displays at around 30 FPS. Higher frame rates are not really necessary, as the human eye cannot typically handle more than about 30 FPS. Some games will average 30 FPS or higher and look choppy. Usually this is due to intense scenes that cause the action to dip below 30 FPS for short periods of time. Rates of over 100 FPS in games are common nowadays with less complex 3D action games, but do not necessarily add to the experience of playing a game.

First Person Shooter (FPS)
This describes a video game that is played from the first person perspective, i.e., looking out of the eyes of the main character. As well, to achieve the “shooter” aspect, the main character usually has some type of weapon, and to achieve your goals you must kill off enemies. The first meaningful game of this genre was Castle Wolfenstein 3D, and other popular examples include the Doom, Quake, and Unreal series.

Shareware, Nagware, Freeware, Open Source - How to differentiate between these computer software industry related terms.

Shareware
Software that can be installed and distributed freely. Some shareware is free but requires fees to be paid to the author before all features are available. Other shareware is full-featured, but “nags” you to pay the fee with extra screens that must be bypassed. Most shareware requires you to pay for it within 30 days.

Nagware
This is shareware that has screens that pop up and require you to press a button or wait an amount of time. These nag screens go away after you pay for the software and enter a registration code.

Freeware
Software that is free for use and does not require a fee to be paid to access its full functionality.

Open Source
Software that can be freely distributed, and must be distributed along with its source code. Thus the source can be changed easily, and the program can be altered to fix bugs or add features. Depending on the Open Source license, you may be unable to redistribute altered code or charge money for the distribution of the software. Some popular examples of Open Source software are Linux and Mozilla.
