E ECC — error checking and correction — A type of memory that includes special circuitry for testing the accuracy of data as it passes in and out of memory. ECP — extended capabilities port — A parallel connector design that provides improved bidirectional data transmission. Similar to EPP, ECP uses direct memory access to transfer data and often improves performance. EIDE — enhanced integrated device electronics — An improved version of the IDE interface for hard drives and CD drives.
HTTP — hypertext transfer protocol — A protocol for exchanging files between computers connected to the Internet. Hyperthreading — hyperthreading is an Intel technology that can enhance overall computer performance by allowing one physical processor to function as two logical processors, capable of performing certain tasks simultaneously. Hz — hertz — A unit of frequency measurement that equals 1 cycle per second.
memory — A temporary data storage area inside your computer. Because the data in memory is not permanent, it is recommended that you frequently save your files while you are working on them, and always save your files before you shut down the computer.

Network connections cannot be protected by surge protectors. Always disconnect the network cable from the network connector during electrical storms.
W W — watt — The measurement of electrical power. One W is 1 ampere of current flowing at 1 volt. WHr — watt-hour — A unit of measure commonly used to indicate the approximate capacity of a battery. For example, a 66-WHr battery can supply 66 W of power for 1 hour or 33 W for 2 hours. wallpaper — The background pattern or picture on the Windows desktop.
