Q.6. Give explanation about various components of Internet.

Ans.                         Components of the Internet

1. World Wide Web (WWW): WWW is a system of Internet servers that supports hypertext to access several Internet protocols on a single interface. Almost every protocol type available on the Internet is accessible on the web. This includes E-mail, FTP, Telnet and Usenet News. In addition to these, the world wide web has its own protocol Hypertext Transfer Protocol or HTTP. 

The world wide web provides a single interface for accessing all these protocols. This creates a convenient and user-friendly environment. It is no longer necessary to be conversant with these protocols within separate, commandBrowser is a Six level environments. The web gathers together these protocols software application used into a single system. Because of this feature and because of the to enable computer users to web’s ability to work with multimedia and advanced programming locate and access web pages. languages, the world wide web is the fastest-growing component of the Internet. 

The world wide web consists of files called pages or home pages containing links to documents and resources throughout the Internet.

2. Hypertext: The operation of the web relies primarily on hypertext as its means of information retrieval. Hypertext is a document containing words that connect to other documents. These words are called links and are selectable by the user. A single hypertext document can contain links to many documents. In the context of the web, words or graphics may serve as links to other documents, images, video and sound. Links may or may not follow a logical path, as each connection is programmed by the creator of the source document. Overall, the www contains a complex virtual web of connections among a vast number of documents, graphics, videos and sounds.

The web provides a vast array of experiences including multimedia presentations, realtime collaboration, interactive pages, radio and television broadcasts and the automatic push of information to a client computer. Programming languages, such as Java, JavaScript and Visual Basic are extending the capabilities of the web. An increasing amount of information on the web is served dynamically from contents stored in databases. The web is therefore not a fixed entity but one that is in a constant state of flux.

3.HTML: Producing hypertext for the web is accomplished by creating documents with a language called Hypertext Markup Language or HTML with HTML tags placed within the text to accomplish document formatting, visual features, such as font size, italic and bold and the creation of hypertext links. Graphics may also be incorporated into an HTML document. HTML is an evolving language, with new tags being added as each upgrade of the language is developed and released. The World Wide Web Consortium, led by web founder Tim Berners-Lee, coordinates the efforts of standardizing HTML.

4. E-mail: Electronic mail or e-mail allows computer users locally and world wide to exchange messages. Each user of e-mail has a mailbox address to which messages are sent. Messages are sent through e-mail can arrive within a matter of seconds.

A powerful aspect of e-mail is the option to send electronic files to a person’s e-mail address. Non-ASCII files, known as binary files, may be attached to e-mail messages. These files are referred to as MIME attachments. MIME stands for Multimedia Internet Mail Extension and was developed to help e-mail software in handling a variety of file-types. For example, a document created in Microsoft Word can be attached to an e-mail message and retrieved by the recipient with the appropriate e-mail program. Many e-mail programs, including Eudora, Netscape Messenger and Microsoft Outlook Express offer the ability to read files written in HTML, which is itself a MIME type.

5. Telnet: Telnet is a program that allows you to log into computers on the Internet and use online databases, library catalogues, chat services and more. To telnet to a computer, you must know its address. It can consist of words (locis.loc.gov) or numbers ( Some services require you to connect to a specific port on the remote computer. In this case, type the port number after the Internet address. For example, telnet nri.reston.va.us 185.

Telnet is available on the world wide web. Probably the most common web based  resources available through telenet are library catalogues.  But it will launch  telnet session to make the connection.  A telnet program must be installed on your  local computer and configured to your web  browser in order to work.

Almost all e-mail programs have the following features:

1. Address book. 2. Signature feature,

3. Attachment facility.

1. Address Book: An address book is a place where you can store information in detail about the people with whom you correspond. The main advantage of having the person’s details in the address book is that you do not have to key in those details each and every time you send a message. You just have to select the person’s name and the e-mail ID will get inserted in the To field.

You can add new addresses in the address book and you can also create groups in the address book. After creating groups, you can send mail to all the members of the group instead of adding each person’s ID into the sending addresses field. You can modify the person’s details or you can delete the person’s name from the address book. If a person has more than one e-mail ID then you can set one among them as default ID.

 (c) E-mail address,(d) Surface mailing address, 

(e) Phone, fax or pager number, (f) Address of your website. 

Some signatures also contain a quote, a joke or philosophical saying.

You can store any or all of the above information which you want to attach at the end of the message as your signature. After creating signature, you can configure your system in such a way that all the outgoing messages will have your signature at the end of the message.

If you do not want to have your signature on all messages, you can uncheck the option. When you need to include the signature on all messages, you can uncheck the option. When you need to include the signature to a message, click on the signature icon and the signature will be appended to the message.

3. Attachments: You can send more than one simple text in your e-mail messages. You can also attach computer documents-including word processor, spreadsheet, graphic and video files to an e-mail message. So, e-mail is a useful way to share files that more than one person want or need.

With Microsoft Outlook 2000, e-mail gets even more sophisticated and easier. Outlook 2000 allows you to send messages on Hypertext Markup Language (HTML) ‘Stationery’ which contains background graphics and special preselected font designs and colour to match. You can now send e-mail directly from any application found in Microsoft Office 2000.
