21 American Standard Code for Information Interchange
"A standard single-byte character encoding scheme used for text-based data. ASCII uses designated 7-bit or 8-bit number combinations to represent either 128 or 256 possible characters. Standard ASCII uses 7 bits to represent all uppercase and lowercase letters, the numbers 0 through 9, punctuation marks, and special control characters used in U.S. English. Most current x86-based systems support the use of extended (or ""high"") ASCII. Extended ASCII allows the eighth bit of each character to identify an additional 128 special symbol characters, foreign-language letters, and graphic symbols."English-Arabic terms dictionary > American Standard Code for Information Interchange

22 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)." -
23 bitness
"A characteristic of a microprocessor's data stream (the distinction between 16-bit, 32-bit and 64-bit address spaces) and the potential differences in instantiation of components that this entails." -
24 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" -
25 hash algorithm
"An algorithm that produces a hash value of some piece of data, such as a message or session key. With a good hash algorithm, changes in the input data can change every bit in the resulting hash value; for this reason, hashes are useful in detecting any modification in a data object, such as a message. Furthermore, a good hash algorithm makes it computationally infeasible to construct two independent inputs that have the same hash. Typical hash algorithms include MD2, MD4, MD5, and SHA-1." -
26 hash function
"An algorithm that produces a hash value of some piece of data, such as a message or session key. With a good hash algorithm, changes in the input data can change every bit in the resulting hash value; for this reason, hashes are useful in detecting any modification in a data object, such as a message. Furthermore, a good hash algorithm makes it computationally infeasible to construct two independent inputs that have the same hash. Typical hash algorithms include MD2, MD4, MD5, and SHA-1." -
27 dword
A data type consisting of a 32-bit unsigned integer. -
28 HDLC
"A protocol for information transfer adopted by the ISO. HDLC is a bit-oriented, synchronous protocol that applies to the data-link (message-packaging) layer (layer 2 of the ISO/OSI reference model) for computer-to-microcomputer communications." -
29 MBR
A characteristic of a data stream in which the same content is encoded at several different bit rates in oder to optimize content delivery. -
30 Secure Hash Algorithm 1
"An algorithm that generates a 160-bit hash value from an arbitrary amount of input data. SHA-1 is used with the Digital Signature Algorithm (DSA) in the Digital Signature Standard (DSS), among other places." -
31 SHA-1
"An algorithm that generates a 160-bit hash value from an arbitrary amount of input data. SHA-1 is used with the Digital Signature Algorithm (DSA) in the Digital Signature Standard (DSS), among other places." -
32 ar-sa عنوان ويب
"A character set for protocols evolving beyond the use of ASCII. The UTF-8 protocol provides for support of extended ASCII characters and translation of UCS-2, an international 16-bit Unicode character set. UTF-8 enables a far greater range of names than can be achieved using ASCII or extended ASCII encoding for character data." -
33 UCS Transformation Format 8
"A character set for protocols evolving beyond the use of ASCII. The UTF-8 protocol provides for support of extended ASCII characters and translation of UCS-2, an international 16-bit Unicode character set. UTF-8 enables a far greater range of names than can be achieved using ASCII or extended ASCII encoding for character data."English-Arabic terms dictionary > UCS Transformation Format 8

35 bits per pixel
"The number of bits (e.g. 8, 16, 24, or 32) used to store and display the color data for a single pixel. This is the standard unit of measure for bit or color depth." -
36 encryption key
A bit string that is used in conjunction with an encryption algorithm to encrypt and decrypt data. -
37 four character code
A 32-bit unsigned integer that is created by concatenating four ASCII characters to identify a data format. -
38 FOURCC code
A 32-bit unsigned integer that is created by concatenating four ASCII characters to identify a data format. -
39 PIC S9(9) COMP Integer
"A 32-bit COBOL data type that represents a 4 byte signed arithmetic operation, and can take on values from -999999999 to +999999999 or -2147483648 to +2147483647, depending on compiler options. A PIC S9(9) COMP Integer is similar to a Long Integer in C." -
40 MD5
"An industry-standard one-way, 128-bit hashing scheme, developed by RSA Data Security, Inc., and used by various Point-to-Point Protocol (PPP) vendors for encrypted authentication."
