EMS (Enhanced Message Service)
An adaptation of the Short Message Service (SMS) that allows
you to send and receive ring tones and service provider's
logo, as well as combinations of simple media to and from
EMS-compliant handsets. Because EMS is based on SMS, it
can use SMS centers the same way that SMS does. EMS
works on all Global System for Mobile communications (GSM)
networks. EMS senders can use text, melodies, pictures,
sounds, and animations to enhance the expressive power of
messages that are limited by the display constraints of mobile
devices.
GPRS (General Packet Radio Service)
New non-voice value-added service that allows information to
be sent and received across a mobile telephone network.
GPRS provides continuous connection to the Internet for
mobile phone and computer users. It is based on the Global
System for Mobile Communication (GSM) circuit-switched
cellular phone connections and the Short Message Service
(SMS).
GSM (Global System for Mobile Communication)
International standard for cellular communication,
guaranteeing compatibility between the various network
operators. GSM covers most European countries and many
other parts of the world.
Java
Programming language generating applications that can run
on all hardware platforms, whether small, medium or large,
without modification. It has been promoted for and geared
heavily to the Web, both for public Web sites and Intranets.
When a Java program runs from a Web page, it is called a
Java applet. When it is run on a mobile phone or pager, it is
called a MIDlet.
