1 data medium
The physical material on which computer data is stored. -
2 data-link layer
"Layer two of the OSI model. A layer that packages raw bits from the physical layer into frames (logical, structured packets for data). This layer is responsible for transferring frames from one computer to another, without errors. After sending a frame, the data-link layer waits for an acknowledgment from the receiving computer." -
3 data transfer
"The movement of information from one location to another, either within a computer (as from a disk drive to memory), between a computer and an external device (as between a file server and a computer on a network), or between separate computers." -
4 data terminal ready
"A signal used in serial communications sent, for example, by a computer to its modem to indicate that the computer is ready to accept an incoming transmission." -
5 data entry
The process of writing new data to computer memory. -
6 Data Collector Set
A computer management tool used to group data collectors into sets that run on the same schedule. -
7 data center
"A facility used to house mission critical computer systems and associated components. It generally includes environmental controls (air conditioning, fire suppression, etc.), redundant/backup power supplies, redundant data communications connections and high security." -
8 Data Execution Prevention
"A security feature that monitors programs on a computer to determine if they use system memory safely. To do this, DEP software works alone or with compatible microprocessors to mark some memory locations as ""non-executable."" If a program tries to run code that is malicious or is not from a protected location, DEP closes the program and notifies you." -
9 Data processing computer

10 host computer
"A computer that acts as a source of information or signals. The host computer provides services, such as news, mail, or data, to computers that connect to it. The term can refer to almost any kind of computer, from a centralized mainframe that is a host to its terminals, to a server that is host to its clients, to a desktop PC that is host to its devices, such as printers and scanners." -
11 offline data source
"A secondary data source that is accessible to users who fill out forms offline. When a user is online, data from the data source is stored on the user’s computer so that it can appear in controls when the form is offline." -
12 Microsoft Data Engine
A client/server data engine that provides local data storage on a smaller computer system and that is compatible with Microsoft SQL Server 2000 and prior. -
13 System Data Source Name
A data source name that can be used by any process on the computer. -
14 digital video disk
"A form of storage characterized by high capacity (roughly 650 MB) and the use of laser optics rather than magnetic means for reading data. Optical disk storage commonly used for audio, video, and computer data. DVDs range in capacity from 4.7 GB to 17 GB, and can store significantly more than a CD-ROM." -
15 DVD
"A form of storage characterized by high capacity (roughly 650 MB) and the use of laser optics rather than magnetic means for reading data. Optical disk storage commonly used for audio, video, and computer data. DVDs range in capacity from 4.7 GB to 17 GB, and can store significantly more than a CD-ROM." -
16 converter
"Any device that changes electrical signals or computer data from one form to another. For example, an analog-to-digital converter translates analog signals to digital signals."محوّل -
17 hardware profile
Data that describes the configuration and characteristics of specific computer equipment. This information can be used to configure computers for using peripheral devices. -
18 64 bit machine
"A computer that works with data in groups of 64 bits at a time. A computer may be considered a 64-bit machine either because its CPU operates internally on 64-bit words or because its data bus can transfer 64 bits at a time. A 64-bit CPU thus has a word size of 64 bits, or 8 bytes; a 64-bit data bus has 64 data lines, so it ferries information through the system in sets of 64 bits at a time. Examples of 64-bit architecture include the Alpha AXP from Digital Equipment Corporation, the Ultra workstation from Sun Microsystems, Inc., and the PowerPC 620 from Motorola and IBM." -
19 host
"A computer that acts as a source of information or signals. The host computer provides services, such as news, mail, or data, to computers that connect to it. The term can refer to almost any kind of computer, from a centralized mainframe that is a host to its terminals, to a server that is host to its clients, to a desktop PC that is host to its devices, such as printers and scanners." -
20 file DSN
file Data Source Names. File-based data sources shared among all users with the same drivers installed. These data sources are not dedicated to a user or local to a computer.
