The Internet, The Web and Electronic Commerce

HTML;
HTML stands for HyperText Markup Language which is a language used to specify the structure of documents for retrieval across the Internet using browser programs of the web.
It is a system of tags used to make web pages. The tags are put before and after text and images, and tell your visitor's browser how the text should appear on the computer screen.

Javascript;
JavaScript is a scripting language used to enable programmatic access to objects within other applications. It is primarily used in the form of client-side JavaScript for the development of dynamic websites. JavaScript is a dialect of the ECMAScript standard and is characterized as a dynamic, weakly typed, prototype-based language with first-class functions. JavaScript was influenced by many languages and was designed to look like Java, but to be easier for non-programmers to work with.

Applets;
Some applets are able to function as any other normal software application (provided they are hosted by an operating system), but are small in size and perform only a small set of tasks. Examples of applications often classified as applets are all of the Accessories in Microsoft Windows (such as Windows Notepad or Microsoft Paint).

Business-to-Consumer E-Commerce;
Business-to-consumer is an electronic commerce business model in which consumers (individuals) offer products and services to companies and the companies pay them.
This business model is a complete reversal of traditional business model where companies offer goods and services to consumers.

Consumer-to-consumer E-commerce;
Consumer-to-consumer or citizen-to-citizen electronic commerce involves the electronically-facilitated transactions between consumers through some third party. A common example is the online auction, in which a consumer posts an item for sale and other consumers bid to purchase it; the third party generally charges a flat fee or commission. The sites are only intermediaries, just there to match consumers. They do not have to check quality of the products being offered.
