HTTP: Hypertext Transfer Protocol, The HTTP is a networking protocol for distributed,
collaborative, hypermedia information systems. HTTP is the foundation of data communication
for the World Wide Web. HTTP functions as a request-response protocol in the client-server
computing model. TFTP: Trivial File Transfer Protocol, TFTP is a file transfer protocol, with the
functionality of a very basic form of File Transfer Protocol (FTP). TFTP could be implemented
using a very small amount of memory. It was therefore useful for booting computers such as
routers which did not have any data storage devices. It is still used to transfer small amounts of
data between hosts on a network, such as IP phone firmware or operating system images when a
remote X Window System terminal or any other thin client boots from a network host or server.
DNS: Domain Name System, The DNS is a distributed hierarchical naming system for computers,
services, or any resource connected to the Internet or a private network. It associates various
information with domain names assigned to each of the participants. Most importantly, it
translates domain names meaningful to humans into the numerical (binary) identifiers associated
with networking equipment for the purpose of locating and addressing these devices worldwide.
MAC: Media Access Control address, The MAC is a unique identifier assigned to network
adapters or network interface cards (NICs) usually by the manufacturer for identification. If
assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered
identification number.
IPv4: Internet Protocol version 4, The IPv4 is the fourth revision in the development of the
Internet Protocol (IP) and it is the first version of the protocol to be widely deployed.
NAT: Network Address Translation
DTMF: Dual Tone Multi Frequency
GSM: Global System for Mobile Communications
