CDMA: Code Division Multiple Access (CDMA) is a 3rd generation digital cellular technology. It is quite popular in the highly competitive cellular service market.  A speciality of CDMA is that it makes available more bandwidth without limiting the frequency range of individual users in the communications network. This facilitates more number of users to communicate on the same network at any given point of time.

C-GREX: C-GREx or Chaos Game Representation Explorer is a handy Bioinformatics tool for exploring the sequence visualization and pattern analysis of biological sequences including RNA, DNA and amino acid sequences.

Cloud Computing: Cloud Computing is an emerging IT delivery model characterized by the new-age, internet-driven economics for increasing the capacities or adding capabilities without investment needs in infrastructure, training or software licensing. Today Cloud Computing is the new lingo for all the IT executives. In Cloud Computing, cloud is only a metaphor. It refers to the range of servers located remotely which hosts computing applications. A very simple illustration of what Cloud Computing Technology is all about is the email applications such as yahoomail or hotmail. Also, if you are using google docs in place of MS word on your Laptop you are very much part of the Cloud Computing environment. Cloud computing benefits include superior user experience, improved workload optimization and service delivery, reduced IT costs and complexities et al. Some of the common examples of Cloud Computing include SaaS (software as a service), MSP ((managed service providers), Utility computing et al.  Cloud Computing is finding its utility in several enterprise applications.

Clustal W: Clustal W is a general purpose alignment program for DNA and proteins. Clustal W boasts of an improved sensitivity for aligning divergent protein sequences.

Cryptanalysis: Cryptanalysis traces its origin from two Greek words. Kryptós means "hidden" while analýein means ‘to loosen’ or ‘to untie’.  It is the practice of codebreaking or cracking the code. Cryptanalysis is the study of methods to get to the exact meaning of encrypted information and typically involves finding a secret key. Thus meaning is obtained without access to the secret information which is general requirement for doing so. In the days of Cyber security threats Cryptanalysis assumes a lot of significance.

Capacitive Accelerometer: Capacitive accelerometers are among the most commercially popular Microelectromechanical systems (MEMS). They are used in engine vibration tests, product shakers, fatigue testing, structural evaluation and a host of other applications. A Capacitive Accelerometer operates on the premise that, there is a repeatable change in capacitance whenever a sensing structure gets deflected due to an imposed acceleration. A Capacitive Accelerometer is similar in operation to a Piezoresistive Accelerometer but is comparatively more sensitive.  Some of the notable features of Capacitive Accelerometers are excellent frequency coverage, high level output signal and immunity to noise interference et al.

Carbon Nanotubes: Carbon Nanotubes are essentially molecular-scale tubes of graphitic carbon displaying electronic and other remarkable properties. The extremely thin Carbon Nanotubes with diameters about 10,000 times smaller than a human hair can be counted among the stiffest and strongest fibres.

Country Code Top level Domain (ccTLD): TLDs with two letters (such as .in - India, .cn-China, .fr- France, .kr -South Korea, .uk - United Kingdom etc) have been established for more than 250 countries and external territories. These are referred to as "country-code" TLDs or judt "ccTLDs". ccTLDs are assigned by IANA or Internet Assigned Numbers Authority based on the ISO 3166-1alpha-2 country codes. Designated managers operate the ccTLDs according to local policies, which are adapted to meet the specific needs of the country or territory involved such as economic, linguistic, cultural and legal circumstances.

Cognitive Science: Cognitive science is an interdisciplinary field encompassing a broad range of both intertwining and contradictory theories about how thinking takes place, how information gets represented and transformed in the brain. Cognitive Science combines insights from several disciplines including artificial intelligence, neuroscience, linguistics et al.

CMOS: CMOS or Complementary metal–oxide–semiconductor is one of the most popular semiconductor fabrication technology characterized by low energy consumption and high switching speeds. CMOS are semiconductors, used extensively in digital logic circuits, such as microprocessors, static RAM and microcontrollers. The reason for the name complementary stems from the fact that both n- and p-MOSFETs are needed by Complementary Metal Oxide Semiconductor (CMOS) circuits. 

Contactless Smart Card: A Contactless Smart Card is used for applications where protecting personal information is paramount along with delivering secure and quick transactions. Some of the common applications include identity cards, payment cards, electronic passports et al. In mass transit systems, Contactless Smart Cards are ideal choice as they can be used without the need for taking out the cards from the purse. Contactless Smart Cards contain embedded smart card secure microcontrollers, internal memory and small antennas. The communication between the chip and the reader takes place through a contactless radio frequency (RF) interface.
