General Packet Radio Service (GPRS)
GPRS is a packet-oriented overlay to Global System for Mobile Communications (GSM) networks supporting connection and connectionless-oriented services and diverse quality-of-service mechanisms. The theoretical maximum speed is 171.2 kilobits per second (Kbps), but real-life user throughput is expected to be 56 Kbps or less.
Graphical User Interface (GUI)
A graphics-based user interface that incorporates movable windows, icons and a mouse. The ability to resize application windows and change style and size of fonts are the significant advantages of a GUI vs. a character-based interface. GUIs have become the standard way users interact with a computer, and the major GUIs are the Windows and Mac interfaces along with Motif for Unix and the GNOME and KDE interfaces for Linux.
