DNA: DNA, or Deoxyribonucleic acid, is the genetic or hereditary material in humans and most of the other living organisms. DNAs are mostly stored in the nucleus of cells and can replicate themselves.
Dielectric Materials: Dielectric Materials are characterized very low electrical conductivity thus they find extensive use in electronics and electrical components. In Dielectric materials electrical fields are sustained with minimal chances for leakage. Solids like glass, plastics, mica and porcelain (ceramic) are good Dielectric materials. A major application of Dielectric materials is in Semiconductor Chips where they are used for insulating transistors from each other.
Decision-Feedback Equalizers: Decision-Feedback Equalizers are nonlinear Equalizers having a forward and feedback filter. A primary advantage of using DFE is that it can cancel ISI (inter-symbol interference) as well as minimize noise enhancement in high speed data communications.
Domain-Name System (DNS): The Domain-Name System (DNS) of the Internet makes it possible for users to refer to Websites as well as other resources using the convenience of domain names (such as "www.icann.org") that are easy to remember in place of all-numeric complex IP addresses that are assigned to each computer on the World Wide Web. The domain names are made up of a series of character strings (also known as "labels") which are separated by dots. TLD(top-level domain) is the name given to the right-most label in a domain. There are essentially two types of TLDs within the DNS. One is called the Country Code Top level Domain (ccTLD) and the other is known as Generic Top Level Domains (gTLDs).
Dot Net: Dot Net (.NET) is a Microsoft software application running on the Windows OS. It provides necessary tools and libraries to the developers enabling them to create Windows software easily and quickly. End users can benefit from Dot Net by getting high quality and secured applications.
Domain Name System: The Domain Name System or DNS in short is a distributed internet directory service. In simple terms it provides the way to locate the internet domains and translate them into IP (Internet Protocols) addresses. The importance of DNS can be understood from the fact that if DNS is slow or fails to work we would not be able to locate web addresses and email transfers stalled.
Dense Wavelength Division Multiplexing: Dense Wavelength Division Multiplexing abbreviated as DWDM constitutes the latest in global network technologies. DWDM is characterised by increased carrying capacity, increased speeds, flexibility and reliability all with a comparatively lesser cost of service. A DWDM optical fiber can at the same time combine effectively and transmit multiple signals over a same DWDM fiber.
