1 data compression
A process for removing redundant data from a digital media file or stream to reduce its size or the bandwidth used. -
2 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." -
3 ar-sa DTMF
"A discrete packet of binary data that has an exceptionally large size, such as pictures or audio tracks stored as digital data, or any variable or table column large enough to hold such values. The designation ""binary large object"" typically refers to a packet of data that is stored in a database and is treated as a sequence of uninterpreted bytes." -
4 BLOB
"A discrete packet of binary data that has an exceptionally large size, such as pictures or audio tracks stored as digital data, or any variable or table column large enough to hold such values. The designation ""binary large object"" typically refers to a packet of data that is stored in a database and is treated as a sequence of uninterpreted bytes." -
5 blob
"A discrete packet of binary data that has an exceptionally large size, such as pictures or audio tracks stored as digital data, or any variable or table column large enough to hold such values. The designation ""binary large object"" typically refers to a packet of data that is stored in a database and is treated as a sequence of uninterpreted bytes." -
6 Microsoft Reserved partition
"A required partition on every GUID partition table (GPT) disk. System components can allocate portions of the MSR partition into new partitions for their own use. For example, when you convert a basic GPT disk to dynamic, the system allocates a portion of the MSR partition to be used as the Logical Disk Manager (LDM) metadata partition. The MSR partition varies in size based on the size of the GPT disk. For disks smaller than 16 GB, the MSR partition is 32 MB. For disks larger than 16 GB, the MSR partition is 128 MB. The MSR partition is not visible in Disk Management, and you cannot store data on the MSR partition or delete it."English-Arabic terms dictionary > Microsoft Reserved partition

The MSR partition is not visible in Disk Management, and you cannot store data on the MSR partition or delete it." -
8 hash
"A fixed-size result that is obtained by applying a one-way mathematical function (sometimes called a hash algorithm) to an arbitrary amount of data. If there is a change in the input data, the hash changes. The hash can be used in many operations, including authentication and digital signing." -
9 message digest
"A fixed-size result that is obtained by applying a one-way mathematical function (sometimes called a hash algorithm) to an arbitrary amount of data. If there is a change in the input data, the hash changes. The hash can be used in many operations, including authentication and digital signing." -
10 hash code
"A fixed-size result that is obtained by applying a one-way mathematical function (sometimes called a hash algorithm) to an arbitrary amount of data. If there is a change in the input data, the hash changes. The hash can be used in many operations, including authentication and digital signing." -
11 PowerPC
"A microprocessor architecture developed in 1992 by Motorola and IBM, with some participation by Apple. A PowerPC microprocessor is RISC-based and superscalar, with a 64-bit data bus and 32-bit address bus. It also has separate data and instruction caches, although the size of each varies by implementation. All PowerPC microprocessors have multiple integer and floating-point units. The voltage and operating speed varies with the implementation. Starting with the PowerPC 740, the microprocessors were manufactured with copper, instead of aluminum, for better performance and reliability." -
12 compression
A process for removing redundant data from a digital media file or stream to reduce its size or the bandwidth used. -
13 compress
"To reduce the size of a set of data, such as a file or a communications message, so that it can be stored in less space or transmitted with less bandwidth." -
14 decompression
"The process of reversing the procedure that is run by compression software. During decompression, the compressed data returns to its original file size and format so it can be accessed or played." -
15 heap
A portion of memory reserved for a program to use for the temporary storage of data structures whose existence or size cannot be determined until the program is running. -
16 pie chart
"A round chart that shows the size of items in a single data series, proportional to the sum of the items." -
17 mini stream
A virtual stream that efficiently stores data objects that are much smaller than the normal sector size. Sectors in this virtual stream are typically 64 bytes in length compared with 512 bytes for normal sectors. -
18 rough order-of-magnitude estimate
"An estimate done without detailed costing, or based on initial or incomplete data. It estimates the general size and scope of a project."English-Arabic terms dictionary > rough order-of-magnitude estimate
-
19 byte
A field size or data type that can hold positive integer numbers ranging from 0 to 255. -
20 bubble chart
"A variation on a scatter chart in which the data points are replaced with bubbles, and three values are compared instead of two. The third value determines the size of the bubble marker."
