Firmware
Firmware is a program or set of programs that have been set permanently into a computer
chip. These are low-level programs that directly manipulate or interact with the hardware.
Firmware is a single program or a combination of programs that have been placed on a
PROM, EPROM or EEPROM prior to the product leaving the manufacturing facility.
GPRS
GPRS stands for General Packet Radio Service. GPRS is a high-speed data transfer
technique, used on GSM networks. It does not require a continuous data stream be opened
between the data source and destination. Instead, it uses packets to move data back and
forth, making efficient use of the available radio spectrum.
GSM
GSM stands for Global System for Mobiles. It is an open, non-proprietary system with
international roaming capability providing seamless and standardized same number contact
ability in more than 170 countries. GSM satellite roaming has extended service access to
areas where terrestrial coverage is not available.
GSM uses digital technology and time division multiple access transmission methods. Voice
is digitally encoded via a unique encoder, which emulates the characteristics of human
speech. This method of transmission permits a very efficient data rate/information content
ratio.
IMEI
IMEI stands for International Mobile Station Equipment Identity.
Internet Protocol (IP)
Internet Protocol works in conjunction with Transmission Control Protocol (TCP). TCP/IP are
part of a group of protocols that provide communication across interconnected networks.
TCP/IP is the protocol used on the Internet. The TCP protocol first establishes a connection
between two systems to send and receive data, and then breaks and sequentially marks the
message into small packets. The IP protocol routes and sends the packets based on the IP
address.
IP Addresses
As with personal computers that access the Internet, modems using GPRS technology also
use Internet Protocol (IP) address, which are used to identify the node or access point for the
modem on the Internet. The service provider assigns this IP address.
The 32-bit host address is usually represented in dotted decimal notation, e.g. 128.121.4.5.
The address can be split into a network number (or network address) and a host number
unique to each host on the network and sometimes also a subnet address.
IP Network
A network of computers that use Internet Protocol allowing a user to access the Internet,
provided that the user has a modem; telephone line, cable line, or wireless data network (e.g.
GPRS); and a service provider.
Local Area Network (LAN)
A computer network that spans a relatively small area (typically up to a 1 km radius), although
most LANS are confined to a single building or group of buildings. This type of networking
allows for easy interconnection of terminals, printers, and computers within a building or
buildings.
