Enhanced Data Rates for GSM Evolution

Enhanced Data Rates for GSM Evolution
EDGE or Enhanced Data rates for GSM Evolution is a technology evolution of GSM and IS-136. The purpose of this new technology development is to increase the speed of data transmission, spectral efficiency, and enable the use of new applications and increased capacity.
Application of EDGE in GSM phase 2 + such as GPRS and HSCSD is done by adding a new physical layer at the side of the Radio Access Network (RAN). So there is no berubahan on the side of the core network such as MSC, SGSN, or GGSN.

Operating system

An operating system (OS) is software, consisting of programs and data, that runs on computers and manages computer hardware resources and provides common services for efficient execution of various application software.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between application programs and the computer hardware, although the application code is usually executed directly by the hardware and will frequently call the OS or be interrupted by it. Operating systems are found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers.
Examples of popular modern operating systems for personal computers are (in alphabetical order): GNU/Linux, Mac OS X, Microsoft Windows and Unix
