Short for blind carbon copy, a copy of an e-mail message sent to a recipient without the recipient’s address appearing in the message. Most e-mail clients include two fields labeled cc and bcc. When you enter addresses in the cc field, the message is copied to those addresses and the cc addresses appear at the top of the e-mail message. When you enter addresses in the bccfield, however, the addresses do not appear in the message. This is useful if you want to copy a message to many people without each of them seeing who the other recipients are.
Short for Backup Domain Controller. BDCs maintain a read-only backup of the PDC’s master directory. Although BDCs cannot be changed, they can be upgraded to PDCs and regularly synchronized with PDCs. Windows 2000 (W2K) approaches the domain controller concept a little differently. Unlike Windows NT, where a PDC must be accessible to make changes to […]
Short for backward explicit congestion notification. A Frame Relay message that notifies the sending device that there is congestion in the network. A BECN bit is sent in the opposite direction in which the frame is traveling, toward its transmission source. Compare with FECN.
- BEDO DRAM
Short for Burst EDO DRAM, a new type of EDO DRAM that can process four memory addresses in one burst. Unlike SDRAM, however, BEDO DRAM can only stay synchronized with the CPU clock for short periods (bursts). Also, it can’t keep up with processors whose buses run faster than 66 MHz.
Short for bit error rate. In a digital transmission, BER is the percentage of bits with errors divided by the total number of bits that have been transmitted, received or processed over a given time period. The rate is typically expressed as 10 to the negative power. For example, four erroneous bits out of 100,000 […]
Acronym for best friends forever. BFF is commonly used in newsgroups, chat rooms, instant messaging, text messaging, SMS, e-mail and other real time text-based communications.
