Presently I am a teacher of TLH-III and Geo-civic.so my student frequently asks many Questions like syllabic and Non-syllabic of which they asked this question as below so please clarify anybody if they aware of it.
thanking you.

Question

1) what does it mean ? GIS ,GPS & GPRS
2) What it is the deference between GIS AND GPS ?

GPS or Global Positioning System is the system that helps one to pin point any location on earth - there are multiple systems today, and GPS specifically refers to the first one that was developed by the US army. This uses multiple satellites (in lower orbits) to pinpoint any location on earth. India is also trying to develop its own satellite system through ISRO's IRNSS

This is a helpful document - http://extension.missouri.edu/eden/Lesson_5/PDF_Readings/L5_GPS_GIS.pdf

GIS or Geographic Information System is more of a software system. It is one which helps us to get more data and with more meaning from the informatio retrieved by GPS. For example GIS can tell you the effects of the recent floods in Chennai. GIS doesnt directly get the data, but it stores, analyses, displays etc - they also allow us interactive queries, provide us data as spatial presentations and maps and also provide results of analyses and operations.

I dont know much about GPRS - just that it is a mobile phone technology. In determining location I think GPRS might use mobile tower locations and base on cells allocated to each tower unlike GPS that uses satellite information. Wikipedia or a basic web search should give quite comprehensive information.

Thank you very much sir for your detail presentation about the GPS & GIS i got clear concept over the matter so and please keep interact with me whenever we needed .thank you once.

General Packet Radio Service
General packet radio service (GPRS) is a packet oriented mobile data service on the 2G and 3G cellular communication system's global system for mobile communications (GSM). GPRS was originally standardized by European Telecommunications Standards Institute (ETSI) in response to the earlier CDPD and i-mode packet-switched cellular technologies. It is now maintained by the 3rd Generation Partnership Project (3GPP).[1][2]

GPRS usage is typically charged based on volume of data transferred, contrasting with circuit switched data, which is usually billed per minute of connection time. Usage above the bundle cap is charged per megabyte, speed limited, or disallowed.

GPRS is a best-effort service, implying variable throughput and latency that depend on the number of other users sharing the service concurrently, as opposed to circuit switching, where a certain quality of service (QoS) is guaranteed during the connection. In 2G systems, GPRS provides data rates of 56–114 kbit/second.[3] 2G cellular technology combined with GPRS is sometimes described as 2.5G, that is, a technology between the second (2G) and third (3G) generations of mobile telephony.[4] It provides moderate-speed data transfer, by using unused time division multiple access (TDMA) channels in, for example, the GSM system. GPRS is integrated into GSM
