1-3 1G 1st Generation Mobile Telecommunications. First generation systems are analog and were designed for voice transfer. AMPS, NMT, TACS, etc are included among first generation systems. With the recent proliferation of PDC/PHS in Japan, post-analog technology has advanced rapidly and consequently only a very few analog systems remain in existence. 2G 2nd Generation Mobile Telecommunications. Second generation systems are digital and are capable of providing voice/data/fax transfer as well as

I IP Internet Protocol. A communication protocol commonly utilised by communication hardware comprising the Internet IPV6 Internet Protocol version 6. lPv6 is the latest IP version. Address exhaustion is prevented by means of a long address field, thereby enabling further Internet expansion. In addition, security and mobility are built into the protocol. Currently utilised IP addresses are almost all 1Pv4, and with the present rate of Internet growth this type of address will be exhausted by 201
