- digital certificate — (communications, security) An attachment to an electronic mail message used for security purposes, e.g. to verify that a user sending a message is who he or she claims to be, and to provide the receiver with the means to encode a reply. An individual wishing to send an encrypted message applies for a digital certificate from a certificate authority (CA). The CA issues an encrypted digital certificate containing the applicant's public key and a variety of other identification information. The CA makes its own public key readily available on the Internet. The recipient of an encrypted message uses the CA's public key to decode the digital certificate attached to the message, verifies it as issued by the CA and then obtains the sender's public key and identification information held within the certificate.
- digital electronics — (electronics) The implementation of two-valued logic using electronic logic gates such as and gates, or gates and flip-flops. In such circuits the logical values true and false are represented by two different voltages, e.g. 0V for false and +5V for true. Similarly, numbers are normally represented in binary using two different voltages to represented zero and one. Digital electronics contrasts with analogue electronics which represents continuously varying quantities like sound pressure using continuously varying voltages. Digital electronics is the foundation of modern computers and digital communications. Massively complex digital logic circuits with millions of gates can now be built onto a single integrated circuit such as a microprocessor and these circuits can perform millions of operations per second.
- digital linear tape — (storage) (DLT) A kind of magnetic tape drive originally developed by DEC and now marketed by Quantum. DLT drives implement the Digital Lempel Ziv 1 (DLZ1) compression algorithm in a combination of hardware and firmware. They use a popular chip by Stac (now hi/fn) to do the string searching. Counting, sorting and Huffman coding are done in firmware (with hardware support for the Huffman algorithm?). In April 1997 DLT drives can transfer 5 megabytes per second and can store 35 gigabytes on a single cartridge. Compression might roughly double these figures.
