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 backslash
"A character used to separate directory names in MS-DOS and UNIX path specifications. When used as a leading character, it means that the path specification begins from the topmost level for that disk drive." -
23 checksum
"A calculated value that is used to test data for the presence of errors that can occur when data is transmitted or when it is written to disk. The checksum is calculated for a given chunk of data by sequentially combining all the bytes of data with a series of arithmetic or logical operations. After the data is transmitted or stored, a new checksum is calculated in the same way using the (possibly faulty) transmitted or stored data. If the two checksums do not match, an error has occurred, and the data should be transmitted or stored again. Checksums cannot detect all errors, and they cannot be used to correct erroneous data." -
24 component
"Any raw material, ingredient, part or item used to assemble a subassembly, finished good, or used as part of a kit." -
25 ENTER key
"The key that is used at the end of a line or command to instruct the computer to process the command or text. In word processing programs, the Enter key is used at the end of a paragraph. Also called: Return key." -

28 master key
"The key used by the client and server for all session key generation. The master key is used to generate the client-read key, the client-write key, the server-read key, and the server-write key. Master keys can be exported as simple key BLOBs." -
29 Options
"A menu choice in many applications that allows the user to specify how the program will act each time it is used. For example, the user may be allowed to specify which view will be used when opening a file, or the default location in which certain file types will be saved." -
30 parity bit
"In asynchronous communications, an extra bit used in checking for errors in groups of data bits transferred within or between computer systems. In modem-to-modem communications, a parity bit is often used to check the accuracy with which each character is transmitted." -
31 physical address extension
"A feature that allows x86-based computers to support more than 4 gigabytes (GB) of physical memory. Up to 64 GB of physical memory can be used as regular 4-kilobyte (KB) pages, and the number of bits that can be used by the kernel to address physical memory can be expanded from 32 to 36."English-Arabic terms dictionary > physical address extension

Primary masters are also used as the first sources for replicating the zone to other DNS servers." -
35 public key
"The nonsecret half of a cryptographic key pair that is used with a public key algorithm. Public keys are typically used when encrypting a session key, verifying a digital signature, or encrypting data that can be decrypted with the corresponding private key." -
36 public key encryption
"A method of encryption that uses a pair of mathematically related keys: a public key and a corresponding private key. Either key can be used to encrypt data, but the corresponding key must be used to decrypt it." -
37 asymmetric encryption
"A method of encryption that uses a pair of mathematically related keys: a public key and a corresponding private key. Either key can be used to encrypt data, but the corresponding key must be used to decrypt it." -
38 AE

Most Web browsers support plug-ins for running these types of files. QuickTime is also part of the new MPEG-4 specification." -
40 registry boot
"The default boot option used by most Windows DNS servers. When registry boot is used, DNS is started and initialized using DNS parameters and their values as they are stored in the Windows registry. You can use a Berkeley Internet Name Domain (BIND) boot file as an alternative to this method of boot configuration for DNS."
