What is E-commerce?
|
E-commerce (electronic-commerce) refers to business over the Internet. Web sites such as Amazon.com, Buy.com, and eBay are all e-commerce sites. The two major forms of e-commerce are Business-to-Consumer (B2C) and Business-to-Business (B2B). While companies like Amazon.com cater mostly to consumers, other companies provide goods and services exclusively to other businesses. The terms "e-business" and "e-tailing" are often used synonymously with e-commerce. They refer to the same idea; they are just used to confuse people trying to learn computer terms.

What is Emoticon?
|
These are the little text-based faces and objects that you often see in e-mail and online chat. They help give the reader a sense of the writer's feelings behind the text. For example, the classic =) face shows that the writer is happy about something or that his message in good humor. The =P face is used to show frustration or to say "Whatever..." Emoticons can also be used to create real-world objects. For example, a @-->-->--- is supposed to be a long-stemmed rose, which you can use to show affection -- pretty lame if you ask me. For a list of common and not-so-common emoticons, check out the Sharpened Emoticons Page.

What is Encryption?
|
Encryption is the coding or scrambling of information so that it can only be decoded and read by someone who has the correct decoding key. Encryption is used in secure Web sites as well as other mediums of data transfer. If a third party were to intercept the information you sent via an encrypted connection, they would not be able to read it. So if you are sending a message over the office network to your co-worker about how much you hate your job, your boss, and the whole dang company, it would be a good idea to make sure that you send it over an encrypted line.

What is End User?
|
An end user is the person that a software program or hardware device is designed for. The term is based on the idea that the "end goal" of a software or hardware product is to be useful to the consumer. The end user can be contrasted with the developers or programmers of the product. End users are also in a separate group from the installers or administrators of the product.
To simplify, the end user is the person who uses the software or hardware after it has been fully developed, marketed, and installed. It is also the person who keeps calling the "IT guy" with questions about why the product isn't working correctly. Generally, the terms "user" and "end user" mean the same thing.

What is Ethernet?

Just to be clear, the first syllable is pronounced "eath" as in "Heath Bar," not like "eth" as in Bethany. Some people find this out the hard way (ridiculing laughter), but at least you don't have to. Ethernet is the most common type of connection computers use in a local area network (LAN). An Ethernet port looks much like a regular phone jack, but it is slightly wider. This port can be used to connect your computer to another computer, a local network, or an external DSL or cable modem.

What is EUP?
|
Stands for "Enterprise Unified Process." EUP is a software development methodology that helps companies create software in an structured and organized manner. It is an extension of the Rational Unified Process (RUP), adding two new development phases -- Production and Retirement. Since the RUP includes four phases, the EUP consists of six phases:
Inception - The idea for the project is stated. The development team determines if the project is worth pursuing and what resources will be needed.
Elaboration - The project's architecture and required resources are further evaluated. Developers consider possible applications of the software and costs associated with the development.
Construction - The project is developed and completed. The software is designed, written, and tested.
Transition - The software is released to the public. Final adjustments or updates are made based on feedback from end users.
Production - Software is kept useful and productive after being released to the public. Developers make sure the product continues to run on all supported systems and support staff provides assistance to users.
Retirement - The product is removed from production, often called "decommissioning." It can either be replaced or simply no longer supported. The release of a new version of software often coincides with the retirement phase of an older version.

What is Exabyte?
|
An exabyte is 2 to the 60th power, or 1,152,921,504,606,846,976 bytes.
It can be estimated as 10 to the 18th power, or 1,000,000,000,000,000,000 bytes. An exabyte is 1,024 petabytes and precedes the zettabyte unit of measurement. While a 64-bit processor can theoretically use 16 exabytes of address space, exabytes are so large, the units are rarely used in a practical context. For example, it is estimated that all the printed material in the world only takes up about five exabytes.

What is Exbibyte?
|
A exbibyte is a unit of data storage that equals 2 to the 60th power, or 1,152,921,504,606,846,976 bytes.
While a exabyte can be estimated as 10^18 or 1,000,000,000,000,000,000 bytes, a exbibyte is exactly 1,152,921,504,606,846,976 bytes. This is to avoid the ambiguity associated with the size of exabytes. A exbibyte is 1,024 pebibytes and precedes the zebibyte unit of measurement
