EAX - Environmental Audio eXtensions
A hardware and software audio standard developed by Creative Labs. It was originally used in SoundBlaster sound boards, and is supported by other companies as well now. EAX offers 3D positional audio and allows the manipulation of sounds so that they can seem to be heard in different listening environments.

ECC - Error Correcting Code
Error Correcting Code: Refers to a type of Memory (RAM) that automatically checks for errors as the data is passed through.

EEPROM - Electrically Erasable Programmable Read-Only Memory
A type of ROM chip that can be erased and reprogrammed electrically. EEPROMs were the most common storage device for BIOS before the advent of Flash ROM.

EIDE - Enhanced Integrated Drive Electronics
Enhanced Integrated Drive Electronics: refers to an interface standard developed by Western Digital, since around the end of 1994 EIDE controllers have been widely used in the PC industry surpassing the earlier IDE standard due to its faster data transfer rates. The interface controls storage devices like hard drives, CD ROM drives, and CD Writers. Seagate introduced their own implementation of the EIDE standard and is commonly known as Fast ATA. Typical EIDE transfer rates are up to 16.6 MBps, the newer Ultra ATA standard which is a variation of EIDE but developed by Seagate can reach data transfer rates of up to 33 MBps.

EPROM - Erasable Programmable Read Only Memory
Erasable Programmable Read Only Memory: Refers to a type of ROM that can be erased using an ultra violet light and then reprogrammed using a PROM Programmer. These chips have a small transparent area on the top, this is where the UV light is directed to clear the contents, they come in various different packages which make them very versatile. The ROM will retain the data until it is exposed again to an ultra violet light, it is normal practise to cover the small transparent area to avoid any potential data loss.

ESD - Electrostatic Discharge
The movement of electrons from one body to another. ESD is a real menace to PCs as it can cause permanent damage to semiconductors.

Ethernet
Ethernet: The most popular system used to connect a computer to a network, including most broadband internet connections. The computer needs to be fitted with a suitable expansion card, usually called an Ethernet card.
