Algorithms are used extensively in computer science, bio-informatics, mathematics et al for calculation, data processing and other tasks. A computer program is one of the most basic.

Bandwidth: In the realm of computer networks, bandwidth refers to the capacity of data/information which can be carried through a channel (typically from website or server) in a given timeTime Where any expression of it occurs in any Rules, or any judgment, order or direction, and whenever the doing or not doing of anything at a certain time of the day or night or during a certain part of the day or night has an effect in law, that time is, unless it is otherwise specifically stated, held to be standard time as used in a particular country or state. (In Physics, time and Space never exist actually-“quantum entanglement”) interval. Bandwidth is thus a synonym for data transfer. As more information is carried through the channel greater is the use of bandwidth. So logically, a video would take up much more bandwidth than for example an e-mail. A bandwidth shortage is said to have occurred when at any point the demand to carry information exceeds the carrier or channel’s capacity. A bandwidth is typically expressed in bits per second (bps).

Black Box: A black box is a device which records the data typically in aircraft or ships and which can be retrieved in case of any eventuality. However, in software development a Black box assumes a different meaning. A Black Box is a testing technique where the tester does not have any knowledge of the intricacies of the program being tested. The tester may know about the input or the output but does not have any inkling of how the results are achieved. A Black Box component is a compiled program that cannot be altered as a programmer is able to access it only through an exposed interface.

Intranet and the Internet :Intranet and the website accessible on the open Internet are essentially two distinct information spaces. There are a number of differences between the two along various dimensions. It is always a good idea to have a separate user interface design to maintain such distinction. This is important because the users should readily know when they are on the internal net (Intranet) and the moment they access the World Wide Web. Further, a different design will also aid in better navigating, sense of place and a clear understanding of information management (information which is internal, secure and confidential vis-à-vis information which is freely shared).

Some of the major differences between an Intranet and the Internet are highlighted here:

Nature of Users: Access to Intranet is mostly open to employees of organisations having a fair idea about the company, its operations, organizational structure, terminologies and circumstances. Access is password protected and accessible only to employees or authorized users. Whereas an Internet site is more of a public face of an organisation accessed by customers with limited knowledge about it and not very keen to know about its day to day functioning.
Nature of Tasks: Intranet applies for facilitating the day to day work within an organisation, this may include complex applications whereas an Internet site maintained by an organisation is for the world to know what it does, product details et al.
Type and Quantum of Information: The Intranet verily by its nature will assimilate a variety of detailed information- draft reports, project status reports, HR information, internal progress and other information, whereas the Internet site primarily delves into more of marketing information as well as customer support information. The amount of information generated also differs. Typically, Intranet contains much more number of pages as compared to an organisation’s website. This can go even upto 100 times. This is chiefly because works by many departments are well documented on the Intranet even though they never publish anything publicly (on the internet).
Navigational System: An Intranet is generally supported by a stronger navigational system as compared to an Internet site. This is because Intranet encompasses a larger volume of information. A navigation system in an Intranet also facilitates movement between Servers whereas an internet public website is required to support within-site navigation.
Design: An Intranet design typically is focussed more on task-orientation and less flashy. There is generally a single Intranet design. An Intranet can be enriched with a large number of options and features without intimidating or overwhelming the users, which can be the case on the open Internet with rapid surfing between sites.
Bandwidth Specifications: Intranets may be accessible from the Internet but their speed is often much faster than Websites typically stuck at low-band or mid-band, server breakdowns and other problems. So it is not uncommon to see applications such as multimedia, rich graphics and other advanced high-bandwidth content, such as audio and video on Intranet pages.

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.

Testbed: A Testbed 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 WiMAX 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 characterised 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.

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.

2G: In the realm of cellCell The smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the cell and controls the substances that go into and out of the cell. The nucleus is a structure inside the cell that contains the nucleolus and most of the cell’s DNA. It is also where most RNA is made. The cytoplasm is the fluid inside the cell. It contains other tiny cell parts that have specific functions, including the Golgi complex, the mitochondria, and the endoplasmic reticulum. The cytoplasm is where most chemical reactions take place and where most proteins are made. The human body has more than 30 trillion cells. phones, 2G refers to the second-generation wireless digital telephone technology. 2G cell-phone networks uses 3 common technologies to transmit information; they are Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA).

3G: 3G supersedes 2g as the third generation of mobile communications systems. It enhances services like multimedia, high speed mobile broadband, internet access with video footage on the mobile handset. With a 3G phone and access to the 3G networks there would be increased bandwidth, and support to diverse applications such as live streaming, video messaging et al.

4G: 4G refers to the fourth-generation of wireless mobile technology which will supercede 3G. A fully operational 4G is widely expected to facilitate pervasive computing-creating an environment where simultaneous connections to multiple high-speed networks will be a seamless handover across a geographical area.

6LoWPAN: 6LoWPAN refers to a new innovation in IP (Internet Protocol) technology. IPv6 over Low power Wireless Personal Area Networks or 6LoWPAN makes the Internet of Things to become a reality. 6lowPAN optimizes the mechanisms of wireless embedded networking.
