www.dell.com | support.dell.com DVD Digital versatile disc. An optical form of storage media, typically used for movies. DVD has improved capacity and bandwidth compared with the CD. Most DVD drives support CD media as well. ECC Error checking and correction. A type of RAM that checks data that is being read or transmitted for errors and, when necessary, corrects the errors. See also EDO. ECP Extended Capabilities Port. A parallel port design that provides improved bidirectional data transmission. Like EPP, it uses DMA to transfer data and often improves performance. Devices such as printers that connect to the computer's parallel port are designed to take advantage of the ECP standard. EDO Extended-data out. A type of RAM that improves the time to read from memory on faster microprocessors such as the Intel Pentium. For faster computers, different types of DRAM are considered. See also ECC. EIDE Enhanced integrated device electronics. An improved version of the IDE interface for hard drives and CD drives. EIDE uses Logical Block Addressing, which allows for hard-drive storage capacities greater than 528 MB. It makes use of DMA channels and can address up to four drives. Also called fast ATA. EMI Electromagnetic interference. Electrical interference caused by electromagnetic radiation. Energy Star A series of EPA requirements to decrease the overall consumption of electricity. EPA Environmental Protection Agency. EPP Enhanced Parallel Port. A parallel port design that provides improved bidirectional data transmission. Like ECP, it uses DMA to transfer data and often improves performance. Many devices that connect to the computer's parallel port are designed to take advantage of the EPP standard. 28
