Data Mining
A set of techniques for sifting through huge amounts of information held in databases, with the aim of discerning useful trends, facts or associations.
Data Transfer / Allowed Bandwidth
The amount of data that you are allowed to view or download from your web site.
Data Warehouse
A collection of databases combining information from different parts of an organization, generally used in conjunction with data mining techniques. A large retailer's data warehouse, for example, may contain information about customer purchases, supplier deliveries, transport vehicle schedules and new products.
Database
A computerized filing system forming the core of most corporate computer systems. Databases are, on the face of it, simple tools used to store and retrieve information. In reality, they are big and complex programs that are subjected to extreme pressure as the demand for sophisticated analysis of corporate data grows.
Datacenter
This is the term for a secure, managed network environment which may house tens or thousands of Web servers with power backup and high-speed connections to the Internet Backbone. Datacenters usually have a mixture of OC-3 and DS-3 connections, or higher (i.e., OC12, OC48, OC 192), and may also have a hard-line connection to a high-speed overseas data trunk (like Global Crossing).
Datagram
A form of packet switching in which the packets that make up the conversation do not all traverse the same path through the network, thus improving the robustness and security of the network
Day Trader

DBMS / DataBase Management System
A program that lets client programs that access the database free from having to know where the physical data is located.
DCOM / Distributed Component Object Model
DCOM is a set of Microsoft concepts and program interfaces in which client program objects can request services from server program objects on other computers in a network. DCOM is based on COM, which provides a set of interfaces allowing clients and servers to communicate within the same computer (that is running Windows 95 or a later version).
D Channel
The ISDN signaling channel, Runs at 16 or 64 Kbps
Dedicated Hosting
A hosting feature that allows a Web site to have its own server but doesn't share the server's resources with any other site The server can usually be configured and operated remotely from the client company. The major benefit is that this allows increased traffic to your sites.
Dedicated server
A dedicated server is when a host provides you your own server on their network. There are no other sites on that server and you have control of the server.
Demon Internet
The first ISP in the UK to offer full dial-up Internet access to consumers
DES / Data Encryption Standard
A widely used method of data encryption judged so difficult to break by the US government that its export to other countries was prohibited.
DHCP / Dynamic Host Configuration Protocol
DHCP, also stands for "Domain Host Control Protocol". A network server uses this protocol to dynamically assign IP addresses to networked computers. The DHCP server waits for a computer to connect to it, and then assigns it an IP address from a master list stored on the server. Using DHCP, managing IP addresses isn't a problem for network administrators.
Dial up
Dialup access is a way of connecting a computer to the Internet using a modem and the telephone line. It is rather slow and blocks the telephone line
Digerati
Movers and shakers in the digital world, especially those celebrated in John Brockman's book of the same name.
Digital Signature
A device that uniquely identifies the sender of an electronic message or document, based on public key cryptography. The purpose of a digital signature is to guarantee that senders of such messages really are who they claim to be, an increasingly important concern for businesses considering E-Commerce Strategies.
Digital Wallet
A consumer account set up to allow e-commerce transactions through a particular credit card processing system. Before the consumer can make a purchase, he or she must first establish an account with the credit card processor, who provides an ID and password. These can then be used to make purchases at any web site that supports that transaction system. CyberCash's "Digital Coin" system is an example of a digital wallet system.
Discount Rate
A percentage fee paid to the merchant account provider or ISO for handling an electronic transaction. Most web merchants pay between two and 10 percent of their revenue from online credit card or electronic check orders.
Disintermediation
The process by which producers and consumers are brought closer together, making middlemen redundant. This ugly word, borrowed from the banking world, is especially relevant to Internet technologies which allow their users direct access to information that might otherwise require a mediator.
Disk Space / Web Space
The amount of storage space you are allowed on the server in which you can store the files that make up your web site.
Distributed Computing
Describes a way of using networked computers to work together collaboratively, using the combined power of their processors to perform large or difficult tasks.
DNS / Domain Name System
A system that maps user-friendly computer host and domain names (e.g., www.hostpulse.com) to IP addresses (e.g., 201.123.28.22). Like telephone numbers, IP addresses uniquely identify computers on the Internet for addressing messages.
Domain Alias
A type of Domain Forwarding; Domain Aliases allow you to access the same page for many sites. This is useful when registering .com, .net, and .org domains at the same time. You only have to provide one account with hosting, and the other two will reference the same page, regardless of whether the user typed .com, .net, or .org.
Domain Name
The unique label that identifies a specific Web site, such as AZC.com; Typically, domain names convey information about a site and are easier to remember than the associated numeric IP address. When a user types a domain name in a browser, the DNS locates the registered domain name and translates that into a numeric IP address.
Domain Name Parking / Domain Parking
When you get a new domain name, you may not have completed your web site yet; You need to have a place to park your domain name under name servers until you are ready to build your web site
Domain name registration
Domain registration is the process of registering a unique name which will identify your web site. Domain names must have an extension, where .com .net and .org are the most popular ones. When registering a domain name, users should keep in mind that domains are tied to name servers, which direct to which IP address the domain should point. Any server can have multiple domain names, but a domain name can only point to one server.
Domain Pointing
Domain pointing transports the visitors from your registered domain name(s) to your existing website.
Domain Redirects
This points additional domains to subdirectories of a main domain.
Domain, top-level
The right-most part of an Internet address, indicating the type and/or location of a user or system. Ex: In the address user@cyberlogichost.com, .com is the top level domain - a commercial domain in this case and cyberlogichost.com is the full domain name.
Domain Transfer
When a domain name (web site) is moved from one Internet address to another, the new address must be recorded by the domain registrar to allow Internet Domain Name Servers to point to the new location.
Download
To retrieve a file from another machine, usually a host machine, to your machine.
DSL / Digital Subscriber Line
Digital Subscriber Line (or, sometimes, Loop). DSL services are designed to improve bandwidth connections over ordinary copper phone lines.
DSSSL / Document Style Semantics and Specification Language
An ISO standard under preparation, addressing the semantics of high-quality composition in a manner independent of particular formatting systems or processes DSSSL is intended as a complementary standard to SGML for the specification of semantics.
DS-3
Connection to Internet Backbone favored by most medium-size Web hosting providers. More than 28 times the bandwidth of a T-1 connection.
DTD / Document Type Definition
The definition of a document type in SGML, consisting of a set of markup tags and their interpretation.
