Introducing the Internet buzz words

World Wide Web

WWW is a part of the Internet which functions using HTML. WWW operates under a protocol called HTTP.

Browser

A browser is a computer software which can be used to view documents on the Internet. Web browsers interpret HTML code and display images and text.

Search Engine.Search engine is an automated web-site which is programmed to search specified keywords and give the websites and Internet based documents as a result.

Client.A computer which is capable of receiving the information from the server in the Internet is called a client. A home PC is an ideal example for this.

Server.Client computers download files in the Internet from the Server. These servers are directly linked to the internet and consist of a lot of documents.

Domain

The Domain is the top level identification string for a particular server (yahoo.com). There are various types of domains. It can be categorized using one or more extensions.

FTP

FTP is a standard Internet protocol which refers to the File Transfer Protocol. Using this protocol we can transfer files from one computer to the other via Internet. This is the simplest way to exchange files between computers on the Internet. FTP is an application protocol that uses the Internet's TCP/IP protocols. FTP is commonly used to transfer Web page files from their creator to the computer that acts as their server for everyone on the Internet. It's also commonly used to download programs and other files to your computer from other servers.

HTML

HTML is the abbreviation for Hyper Text Markup Language. The web pages are called hypertext documents because when you click a word or a picture which is hyper linked you can go to another location. From there you can jump to another webpage. This is made possible because HTML allows the document‟s author to embed hyperlinks.

HTTP

HTTP is the foundation of data communication for the World Wide Web. HTTP (Hypertext Transfer Protocol) is the set of rules for transferring files (text, graphic images, sound, video, and other multimedia files) on the World Wide Web. When the browser user enters file requests by either "opening" a Web file (typing in a Uniform Resource Locator or URL) or clicking on a hypertext link, the browser builds an HTTP request and sends it to the Internet Protocol address (IP address) indicated by the URL. The HTTP daemon in the destination server machine receives the request and sends back the requested file or files associated with the request.

Example URL: http://www.yahoo.com

HTTPS

HTTPS stands for “Hyper Text Transfer Protocol Secure”. This means that the data transferred electronically is encrypted and cannot be accessed by unauthorized people. HTTPS provides authentication of the web-site and related web server which is interacting with thus protecting against Man-in-the middle attacks.

CSS

1. Short for Cascading Style Sheet, CSS is a concept first created by HåkonWium Lie in 1994. In December 1996, CSS was made a specification by the W3C and today allows web developers to alter the layout and appearance of their web pages. For example, CSS may be used to change the font used in certain HTML element, as well as its size and color. A single CSS file may be linked to multiple pages, which allows a developer to change the appearance of all the pages at the same time.

3. E-mail. Message format.

A person can exchange his/her messages digitally through e-mail. E-mail has so many similarities with the postal mail. Similar to a postal mail, e-mail too can be sent from anyone but the mail will be received by the person who owns a particular e-mail address. Of course, you would have used e-mail to convey messages to a person living in another part of the world.
