Firmware Firmware is a computer program that is embedded in a hardware device,
for example a micro controller. Firmware is somewhere between hardware
and software. Like software, it is a computer program which is executed by
a computer. But it is also an intimate and vital part of a piece of hardware,
and has little meaning outside of that particular hardware.
GPRS General Packet Radio Service is a mobile data service available to users
of GSM (see below) mobile phones and modems. GPRS is packet-
switched meaning that multiple users share the same transmission
channel, only transmitting when they have data to send. Thus the total
available bandwidth can be immediately dedicated to users who are
actually sending at any given moment, providing higher utilization where
users only send or receive data intermittently. Usually, GPRS data are
billed per kilobytes of information transferred.
