Low cost business terminals with small antennas (generally less than 2 metres in diameter) are often termed Very Small Aperture Terminals (VSATs). These are usually perceived as being two way data terminals, though strictly speaking many of the systems used for data broadcast are really one-way VSATs. Taking the USA as an example, approximately half of all installed VSATs are only used for one way data links.

Cellular radio has other popular names as cellular mobile or mobile phone. Radio is basically a device, which uses receiver and transmitter. Wireless communication can also be carried out without using radio. The interference caused by high power line to radio transmission is also an example of wireless communication though it is termed as noise. Inductive and conductive circuits and devices can communicate wirelessly for limited distance with less reliability and implementation problem. Therefore, these techniques cannot be termed as radio transmission.

• Trivial file transfer protocol (TFTP) is suited for those applications that do not require complex procedures of FTP and do not have enough resources (RAM, ROM) for this purpose.

• Typical applications of TFTP include loading the image on diskless machine and upgrading the operating system in network devices such as routers.
