21 Active Server component
An OLE Automation component designed to run on the server side as part of a Web application. These components are activated through Active Server Pages (ASP) technology but don't require a Windows interface. -
22 active volume
"The volume from which the computer starts up. The active volume must be a simple volume on a dynamic disk. You cannot mark an existing dynamic volume as the active volume, but you can upgrade a basic disk containing the active partition to a dynamic disk. After the disk is upgraded to dynamic, the partition becomes a simple volume that is active." -
23 ACK
"A message transmitted to indicate that data has been received correctly. The Transmission Control Protocol (TCP) requires that the recipient acknowledge successful receipt of data. Such acknowledgments (ACKs) generate additional network traffic, decreasing the rate at which data passes but increasing reliability. To reduce the impact on performance, most hosts send an acknowledgment for every other segment or when a specified time interval has passed." -

To reduce the impact on performance, most hosts send an acknowledgment for every other segment or when a specified time interval has passed." -
25 address mask
"A number that, when compared by the computer with a network address number, will block out all but the necessary information. For example, in a network that uses XXX.XXX.XXX.YYY and where all computers within the network use the same first address numbers, the mask will block out XXX.XXX.XXX and use only the significant numbers in the address, YYY." -
26 audio call
"A call for transmitting audio data, including but not limited to speech." -
27 Basic authentication
"An authentication mechanism that is supported by most browsers, including Internet Explorer, and encodes (but does not encrypt) user name and password data before transmitting it over the network." -
28 boot partition
"The partition that contains the Windows operating system and its support files. The boot partition can be, but does not have to be, the same as the system partition." -
29 calculator
"Broadly, any device that performs arithmetic operations on numbers. Sophisticated calculators can be programmed for certain functions and can store values in memory, but they differ from computers in several ways: they have a fixed set of commands, they do not recognize text, they cannot retrieve values stored in a data file, and they cannot find and use values generated by a program such as a spreadsheet." -
30 character mode
"A display mode in which the monitor can display letters, numbers, and other text characters but no graphical images or WYSIWYG (""what-you-see-is-what-you-get"") character formatting (italics, superscript, and so on)." -
31 cluster-unaware application
An application that can run on a cluster node and be managed as a cluster resource but that does not support the Cluster API.English-Arabic terms dictionary > cluster-unaware application
-
32 component
"An object that is reusable and can interact with other objects. Note: Every control is a component, but not every component is a control."مكوّن -
33 copy backup
"A backup that copies all selected files but does not mark each file as having been backed up (in other words, the archive attribute is not cleared). Copying is useful if you want to back up files between normal and incremental backups because copying does not affect these other backup operations." -
34 CRC
"A procedure used in checking for errors in data transmission. CRC error checking uses a complex calculation to generate a number based on the data transmitted. The sending device performs the calculation before transmission and includes it in the packet that it sends to the receiving device. The receiving device repeats the same calculation after transmission. If both devices obtain the same result, it is assumed that the transmission was error free. The procedure is known as a redundancy check because each transmission includes not only data but extra (redundant) error-checking values. Communications protocols such as XMODEM and Kermit use cyclical redundancy checking." -
35 cyclic redundancy check
"A procedure used in checking for errors in data transmission. CRC error checking uses a complex calculation to generate a number based on the data transmitted. The sending device performs the calculation before transmission and includes it in the packet that it sends to the receiving device.

Communications protocols such as XMODEM and Kermit use cyclical redundancy checking." -
37 custom recipient
"In Exchange 5.5 and earlier, a custom recipient is a user who is not hosted by Exchange. In Exchange 2003, such users can be added to Active Directory as contacts, Windows users, or users whose Windows accounts are disabled. In any case, they are mail-enabled, but not mailbox-enabled, because their mailboxes are hosted on another messaging system." -
38 dongle
A security device connected to an input/output port to permit the use of a particular software package on that computer. The use of the hardware key hash permits backup copying of software but prevents its unlicensed use on additional computers. -
39 feedback
"The return of a portion of system output as input to the same system. Often feedback is deliberately designed into a system, but sometimes it is unwanted. In electronics, feedback is used in monitoring, controlling, and amplifying circuitry." -
40 file server
A file-storage device on a local area network that is accessible to users on the network. A file server not only stores files but manages them and maintains order as network users request files and make changes to them.
