GPS navigation is common knowledge GlossaryWhat is a PDA:
PDA is the acronym for Personal Digital Assistant , according to Chinese translation known as personal digital assistants, it's just a concept, is a substantially more efficient to help complete the daily chores of electronic equipment, mainly around personal information management (PIM) this topic in spinning , broadly speaking PIM functionality can be achieved in any electronic device can be called a PDA, and more specifically refers to the energy actually portable handheld products . car GPS dvd navigation systemWhat is Bluetooth (Bluetooth)
Was developed by Ericsson early , Nokia, IBM, Intel, Toshiba and other five companies , is a short-range wireless transmission of communications interface , basic communication distance of about 10 meters , the transmission rate of around 721kbps, 2.4G Hz frequency band of operation on support many data transmission and voice communicationsWhat is the SD card (Secure Digital)
Dominated by the Pansomic memory card specification , with the same peripheral input and output capabilities with CF because of the confidentiality of regulatory measures in recent years, favored by many manufacturers , the transmission rate of about 10M / sec.What is MMC (MultiMedia Card)
Hitachi dominated memory card interface , transfer rate of about 2M/sec and SD compatible slot .What is GPRS? What is the difference with GSM ?GPRS is General Packet Radio Service (General Packet Radio Service) the title, was developed in the existing GSM system ,Audi dvd navigation a new set of packet data services . GPRS most fundamental difference with the existing GSM voice systems , GSM is a circuit-switched system , while GPRS is a packet switching system , therefore , GPRS especially suitable for intermittent, sudden or frequent , small amounts of data transmission ,auto dvd player but also to occasional transmission of large data volume . This feature is suitable for most mobile Internet applications.
