A backup that copies all selected files that have been modified the day the daily backup is performed. The backed-up files are not marked as having been backed up (that is, the archive bit is not set).
Digital Audio Tape. Magnetic tape utilizing helical scan to record data. DAT tapes are slightly larger than a credit card in width and height, containing magnetic tape storage capacities of 2 to 24 gigabytes of data. Typical data transfer rates are about 2 MBps. Refer to QIC, Travan.
A service provided by cryptographic technology to assure that data can be read only by authorized users or programs. In a network, data confidentiality ensures that intruders cannot read data. Windows 2000 uses access control mechanisms and encryption, such as DES, 3DES and RSA encryption algorithms, to ensure data confidentiality.
Refer to encryption
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 8 bytes is used for odd parity, resulting in 56 bits of usable key.
A service provided by cryptographic technology that ensures data has not been modified. In a network environment, data integrity allows the receiver of a message to verify that data has not been modified in transit. Windows 2000 uses access control mechanisms and cryptography, such as RSA public-key signing and shared symmetric key one way hash algorithms, to ensure data integrity.
A protocol used primarily for IBM mainframe computers and printer connectivity.
A unit of information transmitted as a whole from one device to another on a network.
