E
EBCDIC (Extended Binary-Coded Decimal Interchange Code)
An IBM code, like the ASCII code, for representing characters with numbers. It allows character data to be transferred via computer. Most computers use the ASCII code.
ECC (Error Correction Code)
A form of error checking used with DRAM memory modules. Unlike parity error checking, using only one bit per byte to check for errors, ECC normally uses three additional bits per byte. It is capable of detecting multiple bit errors and fixing single bit errors.
EDI (Electronic Data Interchange)
Normally used by businesses, EDI is the direct electronic exchange of information from one computer to another using networks.
EDO (Extended Data Out)
A type of DRAM that allows the CPU to access main memory several times faster than previous types could.
EEPROM (Electrically Erasable Programmable Read Only Memory)
EEPROM is memory that retains its data without any power source. EEPROM is erasable and rewritable, even though the abbreviation suggests it is read only.
EIDE (Enhanced Integrated Drive Electronics)
An interface used by different types of disk drives. This interface is around 4 times faster than the older IDE interface. EIDE supports hard drives up to 8.4GB. It can transfer data up to 16.6MBs per second. Also known as ATA-2 and a later revision ATA-3.
EISA (Extended Industry Standard Architecture)
EISA slots connect EISA cards to the motherboard. EISA is a 32-bit interface that operates at speeds up to 8.33MHz. EISA is a later version of the older ISA technology. The 32 and 64-bit PCI interface operates at 33Mhz and 66Mhz. It is has replaced the slower and less efficient EISA interface.
E-mail (Electronic Mail)
The electronic transmission of messages over communication networks like the Internet.
EPROM (Erasable Programmable Read Only Memory)
EPROM stores its information until it is erased with an ultraviolet light. Once Erased, EPROM must be reprogrammed using a special PROM burner.
