SOME BASIC INTERNET CONCEPTS

URL:
Abbreviation of Uniform Resource Locator, the global adress of documents and other resources on the World Wide Web.
The first part of the address is called a protocol identifier and it indicates what protocol to use, and the second part is called a resource name and it specifies the IP address or the domain name where the resource is located. The protocol identifier and the resource name are separated by a colon and two forward slashes.

Web editing: Web editing is basically entereing or modifying contents in a web page.

http: Short for HyperText Transfer Protocol, the underlying protocol used by the World Wide Web. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested Web page.

www: Short for World Wide Web. A system of Internet server that support specially formatted documents.

html: Short for HyperText Markup Language, the authoring language used to create documents on the World Wide Web.

Web browser (examples): Internet Explorer, Firefox...

Web editor (examples): Notepad (included in Windows) and Kate (GNU/Linux).

Web server: A computer that delivers (serves up) Web pages. Every Web server has an I address and possibly a domain name. For example, if you enter the URL http://www.wikipedia.org/index.html in your browser, this sends a request to the server whose domain name is pcwebopedia.com. The server then fetches the page named index.html and sends it to your browser.
Any computer can be turned into a Web server by installing server software and connecting the machine to the Internet. There are many Web server software applications, including public domain software from NCSA and Apache, and commercial packages from Microsoft, Netscape and others.

Search engine (examples): Google, Yahoo... (LINKS: http://google.com, http://yahoo.com)
