The Internet, The web and E-commerce


Business-to-consumer describes a transaction, product or service, or business strategy as targeted to the consumer market rather than the business market. In contrast, if the target is the consumer, the term business-to-consumer, or B2C, applies. A business-to-consumer sale means a sale to a consumer, even of a product normally sold to businesses. For instance, Dell might sell a high-end workstation to a computer game buff in a business-to-consumer sale. Similarly, a business-to-consumer product is one targeted toward consumers rather than businesses. Video games are an example. A business-to-consumer organization, like Proctor and Gamble, gets revenues primarily from consumers, not businesses. Not all businesses and services are exclusively business-to-consumer or business to business. Transaction that occurs between a company and a consumer , as opposed to a transaction between companies. (Business to Business) The term may also describe a company that provide goods or services
for consumers.


Consumer-to-Consumer in e-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 free or commision. The sites are only intermediaries, just there to match consumers. They do not have to check quality of the products being offered.
There are many sites offering free classifieds, auctions, and forums where individuals can buy and sell thanks to online payment systems like PayPal where people can send and receive money online with ease. eBay's auction service is a great example of where person-to-person transactions take place everyday since 1995.


E-Commerce or electronic commerce, is a subset of e-business, which is the purchasing, selling, and exchanging of goods and services over computer network through which transactions or terms of sale are performed electronically. In short, E-commerce is the buying and selling of goods and services on the Internet. In practice, this term and e-business are often used interchangeably. For online retail selling, the term of e-tailing is sometimes used. E-commerce can also be broken down into four main categories which are Business to Business, Business to Consumer, Consumer to Business, and Consumer to Consumer.

Internet Security Suite

JavaScript is programming or script language from Netscape. JavaScript code can be imbedded in HTML pages and interpreted by the Web browser (or client). JavaScript can also be run at the server as in Microsoft's Active Server Pages before the page is sent to the requestor. It is somewhat similar in capability to Microsoft's Visual Basics, Sun's TCL, the UNIX-derive Perl, and IBM's Rexx. In general, script languages are easier and faster to code in than the more structured and compiled languages such as C and C++. Script languages generally take longer to process than compiled languages, but are very useful for shorter programs. JavaScript is also used in Web site development to do things like automatically change a formatted date on a Web page, cause a linked-to page to appear in a pop-up window, or cause a text or a graphic image to change during a mouse rollover.


In computing, a plug-in consists of a computer program that interacts with a host application to provide a certain, usually very specific, function "on demand". Add-on is often considered the general term comprising plug-ins, extensions, and themes as subcategories. Most graphics and audio programs today support plug-ins since they are a convenient way to expand the capabilities of the program. Though some plug-ins may be shipped with the program, most are developed by third-parties and are sold separately. Plug-in is a hardware or software module that adds a specific feature or service to an existing application in order to enhance it's capability. A software plug-in is an add-on for a program that adds functionality to it. For example, a Photoshop plug-in (such as Eye Candy) may add extra filters that you can use to manipulate images. A browser plug-in (such as Macromedia Flash or Apple QuickTime) allows you to play certain multimedia files within your Web browser. VST plug-ins add effects for audio recording and sequencing programs such as Cubase and Logic Audio.


Spam is an unsolicited commercial advertisements distributed online. Most spam comes to people via email, but some spam also can be found in online chat rooms and message boards. Some people also label spam as any form of Internet advertising such as pop up browser windows. Besides, spam consumes a tremendous amount of network bandwidth on the Internet. Spam's continued existence depends on maintaining an audience of people who respond to the messages. In contrast to true spam, these forms of advertising are provided to people in the act of visiting websites are merely a "cost of doing business" to help support those sites' products and services.
