Traditional security systems store security statements in a variety of data structures....
What Does Bit Valley Mean? Bit Valley is an area of Shibuya, a suburb of Tokyo, that housed many of Japan’s Internet startups during the dot-com boom. The name Bit Valley is a play on the English translation of Shibuya (bitter valley) and the computer term, “bit.” Bit Valley was seen as the Japanese answer to Silicon Valley, but it did not achieve the size and scale of its U.S. cousin before the dot-com bubble burst....
What Does Cellular Digital Packet Data (CDPD) Mean? Cellular digital packet data (CDPD) was a wireless data service used to access the Internet and other packet-switched systems over a cellular network. CDPD was normally used by analog advanced mobile phone system (AMPS) standards and was one of the first generation cellular frequencies. From 1995 to 1996 the CDPD protocol was standardized to answer wireless Web service demands. The technology utilized idle or unused channels operating at 800-900 MHz carriers serving speeds of up to 19....
What Does Co-location (Colo) Mean? Co-location refers to the way IT equipment and resources are located or installed. This usually refers to the networking hardware resources owned by an organization, such as Web or database servers, which are located outside the vicinity of the organization’s premises and “co-located” with another organization’s hardware, usually an ISP or a service provider. This is usually done because the ISP might be the best candidate for maintaining the Web server hardware for the organization and it would be better to keep the hardware in a more suitable place since ISPs have specially built places for networking hardware....
What Does Deep Packet Capture (DPC) Mean? Deep packet capture (DPC) is the process of capturing all of the data packets passing through or from a network medium. It is a type of packet filtering, analysis and traffic logging technique used to capture and view packets that typically aren’t detected by a standard packet monitoring or filtering solution. Deep packet capture might also be called deep packet sniffing. Techopedia Explains Deep Packet Capture (DPC) DPC is primarily a network analysis, monitoring and optimization technique to evaluate all the different packets that flow within a network or device....

What Does Emacs Mean? Emacs is a class of cross-platform highly-customizable text editors created by Richard Stallman. The first Emacs was released in 1976. Today, Emacs is developed under the GNU project and written in C and Emacs Lisp. Emacs has many types, but GNU Emacs and XEmacs are the two most popular versions. Emacs text editors offer different content-sensitive modes for plain text, programming source codes and HTML code. Such modes feature syntax highlighting, where different colors are used to highlight different syntax elements (like loops, comments, variables, etc)....
What Does Extra-high Density (ED) Mean? The term extra-high density disk in IT refers to a specific kind of floppy disk with a specific amount of storage capacity. This term is actually a bit controversial in its usage, because of different storage capacity designations for these types of storage media. Techopedia Explains Extra-high Density (ED) In some cases, sellers or others advertise floppy disks with a storage capacity of 2.88 MB as extra-high density or ED disks....
Key Points: Fuzzy matching is basically when a computer, or program, tries to correctly determine the intent of an input (from a human user, say) when there is a typo, missing letter, incorrect spelling, etc. The term fuzzy is used because the “Iines are blurred” when you consider how a computer normally considers data with strict logical rules. Uses of fuzzy matching can be seen in Google searches, apps like Shazam, and in spell-checking....
