Well Shahnawaz all the terms asked by you are relaed to mobile tecnology.
"General Packet Radio Service" is the full form of GPRS.
It is a radio technology for GSM (Global System for Mobile
communications) networks that adds packet-switching protocols, shorter set-up time for ISP connections, and offer the possibility to charge by amount of data sent rather than connect time. GPRS promises to support flexible data transmission rates typically up to 20 or 30 Kbps (with a theoretical maximum of 171.2 Kbps), as well as continuous connection to the network.
"Global System for Mobile communications" is the full form of GSM.
It is the most widely used digital mobile phone system and the de facto wireless telephone standard in Europe. Originally defined as a pan-European open standard for a digital cellular telephone network to support voice, data, text messaging and cross-border roaming. GSM is now one of the world's main 2G digital wireless standards.
Final one : "Code Division Multiple Access" is the full form of CDMA.
CDMA allows multiple frequencies to be used simultaneously (Spread Spectrum).
The CDMA idea was originally developed for military use over 30 years ago.
