Transceiver: A Transceiver is a device having transmission and reception capability in a single package. A most common illustration of Transceiver is a cellular phone that can both receive and send data. Transceiver has become the foundation for wireless communications devices.

Text to Speech System: Text to Speech System abbreviated as TTS is a technique to convert the words of the computer text into audible speech.  With a TTS engine application, email messages can be listened. TTS systems are especially proving a major boon to those who are visually challenged.

Test bed: A Test bed refers to the execution environment that enables software testing under normal working conditions. A test bed consists of OS, specific software/hardware, configuration of the product to be tested et al.

Terabyte: A Terabyte often shortened to TB with the prefix Tera meaning monster in Greek while byte is derived from bite. Terabyte measures a computer’s storage capacity. A Terabyte equals 1012 bytes.

Ultra Wideband: Ultra-Wideband (UWB) technology is a power-efficient short-range radio technology which is best suited to WPANs (Wireless Personal Area Networks) UWB complements existing long range radio technologies like Wi-Fi and Wi MAX and provides high bandwidth solution for multiple digital video and audio streams. A
UWB transmitter sends billions of pulses across a very wide frequency spectrum that is several GHz in bandwidth.  The pulses are then translated into data by the corresponding receiver by listening to the familiar pulse sequence that is sent by the transmitter. UWB is characterized by larger spectrum, low power consumption and pulsed data. This results in improved speed and a considerably reduced interference with other Wireless spectra.

Wavelength: In the electromagnetic spectrum, wavelength is the complete distance of a wave cycle between any two points in the same phase.

Wi Fi: Wireless Fidelity or Wi-Fi refers to certain types of wireless local area network (WLAN) used across the world. Wifi networks can be of two types, the open type where anyone can have access or the closed type requiring passwords.

Wi-MAX: Worldwide Interoperability for Microwave Access shortened to Wi-MAX is a broadband wireless network technology that utilises fixed antennas for providing 2-way broadband connections to consumers over distances.

WLAN: WLANs or Wireless Local Area Networks is a local area network that offers wireless network communication over relatively shorter distances. With WLAN there is flexibility to the networking by using radio or infrared signals or an extension to the current wired network.

W3C: Tim Berners-Lee, the World Wide Web’s inventor founded the World Wide Web Consortium or W3C in short. W3C’s mission is to fully develop the www to its potential. W3C is trying to promote the long-term growth of the Web by transcending the barriers of language, geography, cultural differences, mental prowess along with software, hardware, network infrastructures et al.  Recently the W3C has opened its India office.

XML: XML or Extensible Markup Language is a widely-implemented standard for data exchange. Data records and documents using XML are platform-independent and fully portable.  With XML, exchanging data between incompatible systems is distinctly possible.

Zigbee Modules: ZigBee modules are essentially transceiver modules that add wireless networking capabilities to electronic devices. They are used in remote monitoring machine-to-machine communications, automation systems in home and offices, fridges, wireless sensor networks along with other applications.

Zinc Finger: For Proteins to form a stable structure there is inter-working of hundreds of amino acids. On the other hand, there is a shortcut way for proteins to form a solid stable structure in all plants and animals.  This is done using Zinc atoms which acts as a magnet attracting certain type of amino acids. The resultant protein is known as Zinc Finger. In Zinc Fingers, 2 numbers Cysteines and Histidines are arranged close to each other in a chain. This arrangement makes it possible for a protein to grab a zinc ion and then fold tightly around it. Thus in the Zinc Fingers, a short chain of 20-30 amino acids is sufficient towards creating a solid, stable Protein structure.

The diagram shown here is of a typical C2H2 zinc-finger motif. The Cysteines (C) and Histidines (H) are shown in yellow and blue. They are paired and bind the zinc ion. The linker sequence (represented in green) with its consensus sequence in the amino acid code (single-lettered), joining the adjacent fingers.  This is evident in the lower part which depicts a typical structure of fingers in a C2H2 ZNF protein.
