E-mail Electronic mail. The sending and receiving of electronic messages, including text and graphics.
Easter Egg The pinball game hidden in Microsoft Word. The flight simulator concealed in Excel. The animated list of contributors tucked into a hidden folder of Windows 95. These are just a few examples of Easter Eggs: undocumented programs--usually games or elaborate screen shows--that programmers hide in applications. Entire Web sites have been created to alert you to the Easter Eggs in your favourite programs.
EBCDIC Acronym for Extended Binary Coded Decimal Interchange Code. It is the standard 8-bit code with a 9th bit for parity checking as used by IBM microcomputers.
ECC RAM Error Checking and Correction (ECC) RAM is a type of memory that actually corrects errors rather than simply detecting them, as its predecessor parity RAM does. ECC RAM is both cheaper and more advanced than parity RAM and is therefore becoming more popular.
ECML The new Electronic Commerce Modeling Language (ECML) specification aims to make the new "electronic wallet" programs compatible with a wide variety of Web shopping sites. It should automate the process of filling in Web forms.
EDI Acronym for Electronic Data Interchange. It is based on industry, national or international standards.  It is the transmission and reception of business data by a company and its partners, customers and agents.
EDO RAM Extended Data Out (EDO) RAM is memory that allows the processor to start accessing another memory location while still receiving data from the previous access. This type of memory is predominantly used in servers.
EIDE Enhanced IDE (EIDE) is an improved version of IDE.
Encryption Encryption is the method in which data is rearranged so that it cannot be read without approval. Without a key, or electronic "answer book," it cannot be decrypted. A practical example of encryption is when you make an purchase online and have to enter your credit card number. For security purposes, your number is encrypted to avoid theft, fraud, or any other number of nasty things.
Energy Star The Energy Star label means your system is able to conserve power, depending on the settings you've chosen. For example, you can have the monitor shut off automatically after a set amount of time, or have your system go into standby mode after so many minutes of inactivity. Tosee if your PC is Energy Star compliant, just right click anywhere on the desktop, select Properties, then select the Screen Saver tab. You should see the little Energy Star logo. If it's not there, look around the outside of your monitor for a sticker.
Error Correction A method of correcting errors arising during the transmission, storage or transfer of data.  It enables the process to continue with a slight pause.   Without it, any transmission, storage or transfer would be unsuccessful.
EULA EULA stands for "end-user license agreement"--essentially, a list of rights you waive away in exchange for getting to use a software program. Once short legal notices absolving software manufacturers of unreasonable liability, EULAs have evolved into lengthy monologues, which, if actually read, would scare many people away.
Exabyte An exabyte equals 1,024 petabytes.Or equal to 2 to the 60th power bytes--or precisely 1,152,921,504,606,846,976 bytes.
Executable You have all seen files with the .EXE extension. That file is an executable. This means that the file runs automatically when you click on it (and to run a program is known as "executing" the program). Keep in mind that an executable doesn't have to end with EXE. Files ending in .BAT or .COM are executables as well. Because executables open automatically, it's a good idea to be wary of ones that arrive as an e-mail attachment, as they may contain a virus.
Extranet An intranet that allows access to, and is partially accessible from, the Internet. You might set up an extranet to give your employees access to the Internet and/or to give business partners, vendors, and even certain customers access to certain areas of your corporate intranet, such as your inventory or pricing applications. Many larger companies today have some form of extranet.
