21 refresh interval
"An interval of time used by of a zone to determine how often to check if their zone data needs to be refreshed. When the refresh interval expires, the secondary master checks with its source for the zone to see if its zone data is still current or if it needs to be updated using a zone transfer. This interval is set in the SOA (start-of-authority) resource record for each zone." -
22 retry interval
"The time, in seconds after the refresh interval expires, used by secondary masters of a zone to determine how often to try and retry contacting its source for zone data to see if its replicated zone data needs to be refreshed. This interval is set in the for each zone." -
23 spinlock
A locking mechanism associated with a global data structure. This mechanism ensures that only one thread can get access to the data structure at any given time. -
24 simple recovery model
"A database recovery mode that minimally logs all transactions sufficiently to ensure database consistency after a system crash or after restoring a data backup. The database is recoverable only up to the time of its most recent data backup, and restoring individual pages is unsupported." -
25 isochronous
"Pertaining to processes where data must be delivered within certain time constraints. Multimedia streams require an isochronous transport mechanism to ensure that data is delivered as fast as it is displayed, and to ensure that the audio is synchronized with the video." -
26 LINQ to SQL
"A LINQ technology that provides a run-time infrastructure for managing relational data as objects. In LINQ to SQL, the data model of a relational database is mapped to an object model expressed in the programming language of the developer." -
27 fill series
"A sequence of data such as numbers, number and text combinations, dates, or time periods, based on an established pattern and used to automatically fill data into worksheet cells." -
28 profiling
"The collection of detailed performance data, such as memory, stack frame, and CPU utilization, during application execution. Analysis of the resulting data often leads to code optimizations that substantially improve application run-time behavior." -
29 transfer rate
"The rate at which a circuit or a communications channel transfers information from source to destination, as over a network or to and from a disk drive. Transfer rate is measured in units of information per unit of time -- for example, bits per second or characters per second -- and can be measured either as a raw rate, which is the maximum transfer speed, or as an average rate, which includes gaps between blocks of data as part of the transmission time." -
30 Message Authentication Code
An algorithm that allows a receiver to ensure that a block of data has retained its integrity from the time it was sent until the time it was received.English-Arabic terms dictionary > Message Authentication Code
-
31 MAC
An algorithm that allows a receiver to ensure that a block of data has retained its integrity from the time it was sent until the time it was received. -
32 cycle chart
"A chart that surfaces cyclical patterns in data by comparing the performance for certain time periods, such as days of the week or months, over time." -
33 Timeline
"A graphic control that allows users to select time periods for data filtering, using a familiar linear time representation." -
34 active cell
The selected cell in which data is entered when you begin typing. Only one cell is active at a time. The active cell is bounded by a heavy border. -
35 current cell
The selected cell in which data is entered when you begin typing. Only one cell is active at a time. The active cell is bounded by a heavy border. -
36 burst
Transfer of a block of data all at one time without a break. Certain microprocessors and certain buses have features that support various types of burst transfers. -
37 calculated control
"A control used on a form, report, or data access page to display the result of an expression. The result is recalculated each time there is a change in any of the values that the expression is based on." -
38 calculated field
A field defined in a query that displays the result of an expression rather than displaying stored data. The value is recalculated each time a value in the expression changes. -
39 column chart
A graph that uses vertical bars to show data changes over a period of time or illustrate comparisons among items. -
40 column graph
A graph that uses vertical bars to show data changes over a period of time or illustrate comparisons among items.
