Simply another name for information. While data is correctly known as bits of electronic information stored for computer use, it can also be information written on paper, information stored in our heads, or any other type of information.
A collection of data. A filing system capable of accepting data. Normally referred to as a well organized and easily accessible computer filing system containing a collection of information. A database can also be a file cabinet or any other item that stores data.
Also known as a dedicated channel. A line or channel dedicated for a specific purpose. A dedicated phone line for a computer would be a phone line reserved for the computers use only.
DHTML (Dynamic Hypertext Markup Language)
A variation of HTML that allows much better movement, manipulation, and interactivity with WebPages. A user is able to interact with DHTML WebPages without having to go through the Web server. With DHTML better WebPages video games and other things are possible than with regular HTML.
Non-continuous. Computers are digital. They process information bits at a time. Computers can convert analog information into digital information for processing then back into analog again. A sound card can take your voice, (analog), convert it into digital, (for processing), then convert it back into analog again, playing it through the speakers. A digital clock is a good example of how digital information is handled. The numbers on the clock go from one to the next, stopping for a split second in-between. Clocks with hands move continuously in a slow and steady circular motion, (analog). They never stop moving unless the power goes out.
DIMM (Dual In-Line Memory Module)
A memory expansion card that has several memory chips. There are contact points on both sides of this type of module. The contact points are not connected.
DLL (Dynamic Link Library)
DLL files are used by programs to access commonly needed functions used with Windows. Programmers use them to eliminate having to write extra code. These files are often shared between many different programs. The winsock.dll file is one example. Programmers can use the winsock.dll functions to eliminate having to write a tremendous amount of extra code to connect to different types of modems, configure the connection, specify protocols that will be used, and many other things. Instead they may only need to write one line of code as simple as "openWinsock1." A few more lines of code will probably be needed to complete the connection, but by using the winsock.dll file the programmer has eliminated having to write hundreds, if not thousands, of extra lines of code.
DMA (Direct Memory Access)
DMA refers to accessing the computer's main memory from a device, (like a hard drive), without having to go through the central processing unit.
DMI (Desktop Management Interface)
DMI enables programs to collect information about the computer environment. It can obtain information like what kind of hardware or programs are installed on a computer.
DOS Disk Operating System
An older 16 bit operating system. DOS is still available on most computers, but people rarely use it today. Computer technicians often use it to access a computer that is having problems starting normally. With time, DOS will probably become obsolete.
A keyboard and monitor hooked to a remote computer. The dumb terminal can send and receive information, but it lacks the ability to alter the primary computer's information. It cannot process data or store data by itself. It can only enter, transmit, receive, and display data.
