1 block diagram with perspective
"A type of block diagram that contains 3-D geometric shapes, directional lines, and a vanishing point for changing depth and perspective. Use for functional decomposition, hierarchical, and data structure diagrams."English-Arabic terms dictionary > block diagram with perspective

2 Data Encryption Standard
"An encryption algorithm that uses a 56-bit key and maps a 64-bit input block to a 64-bit output block. The key appears to be a 64-bit key, but one bit in each of the eight bytes is used for odd parity, resulting in 56 bits of usable key." -
3 authentication data
"A scheme-specific block of data that is exchanged between the server and client during authentication. To prove its identity, the client encrypts some or all of this data with a user name and password. The client sends the encrypted data to the server, which decrypts the data and compares it to the original. If the decrypted data matches the original data, the client is authenticated." -
4 network control block
"NetBIOS data structures that contain information about the command to perform an optional post routine, an optional event handle, and a pointer to a buffer that is used for messages or other data." -
5 buffer control block
An opaque structure in the cache manager that maintains state as a file system pins and releases data in the cache. -
6 padding
"In data storage, the addition of one or more bits, usually zeros, to a block of data in order to fill it, to force the actual data bits into a certain position, or to prevent the data from duplicating a bit pattern that has an established meaning, such as an embedded command" -
7 cookie
"On the World Wide Web, a block of data that a Web server stores on a client system. When a user returns to the same Web site, the browser sends a copy of the cookie back to the server. Cookies are used to identify users, to instruct the server to send a customized version of the requested Web page, to submit account information for the user, and for other administrative purposes." -
8 bitmap
"A data structure in memory that represents information in the form of a collection of individual bits. A bit map is used to represent a bit image. Another use of a bit map in some systems is the representation of the blocks of storage on a disk, indicating whether each block is free (0) or in use (1)." -
9 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. -
10 volume bitmap
A stored reference (which may exist both on hierarchical directory volumes and in memory) to every piece of data that is in the allocation blocks and indicates whether the block is allocated or free for use. -
11 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
-
12 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. -
13 sparing table
A remapping table in the UDF file format that allows defect management with disk/drive systems that do not typically perform defect management (e.g. CD-RW) by reallocating the data at the file system layer when a defective block is encountered. -
14 sender reputation
"Anti-spam functionality that is enabled on computers that have the Edge Transport server role installed to block messages according to characteristics of the sender. The Sender Reputation agent continuously monitors senders and their past Simple Mail Transfer Protocol (SMTP) interactions, such as the amount of spam and messages that are not spam that a sender has sent, and relies on persisted data about the sender to determine what action, if any, to take on an inbound message." -
15 buffer pool
A block of memory reserved for index and table data pages. -
