Electronic commerce

Electronic commerce, commonly known as e-commerce or eCommerce, consists of the buying and selling of products or services over electronic systems such as the Internet and other computer networks. The amount of trade conducted electronically has grown extraordinarily since the spread of the Internet. A wide variety of commerce is conducted in this way, spurring and drawing on innovations in electronic funds transfer, supply chain management, Internet marketing, online transaction processing, electronic data interchange (EDI), inventory management systems, and automated data collection systems. Modern electronic commerce typically uses the World Wide Web at least at some point in the transaction's lifecycle, although it can encompass a wider range of technologies such as e-mail as well.

A large percentage of e-commerce is conducted entirely electronically for virtual items such as access to premium content on a website, but most electronic commerce involves the transportation of physical items in some way. Online retailers are sometimes known as e-tailers and online retail is sometimes known as e-tail. Almost all big retailers have electronic commerce presence on the World Wide Web.

E-commerce that is conducted between businesses is referred to as business-to-business or B2B. B2B can be open to all interested parties (e.g. commodity exchange) or limited to specific, pre-qualified participants (private electronic market). Electronic commerce that is conducted between businesses and consumers, on the other hand, is referred to as business-to-consumer or B2C. This is the type of electronic commerce conducted by companies such as Amazon.com.

E-commerce is generally considered to be the sales aspect of e-business. It also consists of the exchange of data to facilitate the financing and payment aspects of the business transactions.

Archive

An archive refers to a collection of historical records, and also refers to the location in which these records are kept.

'Archives' are made up of records (AKA primary source documents) which have been accumulated over the course of an individual or organization's lifetime. For example, the archives of an individual may contain letters, papers, photographs, computer files, scrapbooks, financial records, diaries or any other kind of documentary materials created or collected by the individual--regardless of media or format. The archives of an organization (such as a corporation or government), on the other hand, tend to contain different types of records, such as administrative files, business records, memos, official correspondence, meeting minutes, and so on.

In general, archives of any individual or organization consist of records which have been especially selected for permanent or long-term preservation, due to their enduring research value. Archival records are normally unpublished and almost always unique, unlike books or magazines, in which many identical copies exist. This means that archives (the places) are quite distinct from libraries with regard to their functions and organization, although archival collections can often be found within library buildings.

Archives are sometimes described as information generated as the "by-product" of normal human activities, while libraries hold specifically authored information "products".

A person who works in archives is called an archivist. The study and practice of organizing, preserving, and providing access to information and materials in archives is called archival science.

Archivists tend to prefer the term 'archives' (with an S) as the correct terminology to serve as both the singular and plural, since 'archive,' as a noun or a verb, has meanings related to computer science.
