DHCP – Dynamic Host Configuration Protocol

A protocol used by networked computers (clients) to obtain IP addresses and other parameters such as the default gateway, subnet mask, and IP addresses of DNS servers from a DHCP server.

DHCP server

DNS – Domain Name System (or Service) The distributed name/address mechanism used in the Internet. It comprises distributed online databases that contain mappings between human-readable names and IP addresses, and servers, which provide translation services to client applications.

DTMF – Dual Tone Multi Frequency The telephone signaling method used over

the line in the voice-frequency band to the call switching center. The version of DTMF used for telephone “tone dialing” is known by the trademarked term “Touch-Tone”.

EDGE – Enhanced Data rates for Global Evolution

A technology that gives GSM the capacity to handle services for the third generation of mobile telephony. EDGE provides three times the data capacity of GPRS.

Encryption

Encryption is an effective way to achieve data security by translating data into a secret code.

Encryption key

A sequence of characters used for data encryption. The encrypted data can only be sent and received by users with access to the encryption key.

Ethernet

The most common LAN technology, used in wired networks.

FTP – File Transfer Protocol

A protocol for exchanging files over the Internet. FTP is most commonly used to download and upload files from and to servers.

Gateway

A network point that acts as an entrance to another network.

GPRS – General Packet Radio Service

Apacket-based mobile communications system building on GSM. Advantages over standard GSM include higher data transmission speeds, more efficient use of radio resources and continuous connection to the network to facilitate more advanced non- voice services.

GSM – Global System for Mobile Communication

The second generation mobile system originally developed in Europe. GSM is oriented to voice and circuit mode data.

Host

A device (usually a computer) that is connected to a TCP/IP network, including the Internet. Each host has a unique IP address.

Host name

The DNS name of a device on a network, used to simplify the process of locating computers on a network.

HSPA – High Speed Packet Access

A mobile broadband technology that improves the performance of networks based on the Universal Mobile Telecommunications System (UMTS).
