But what does one do with the Internet? May be four things, basically: mail, discussion groups, long-distance computing, and file transfers. Internet mail is (e-mail or electronic mail), much faster as compared to normal postal mail. One can also send software and certain forms of compressed digital image as an attachment. News groups or discussion groups facilitate Internet user to join for various kinds of debate, discussion and news sharing. Long-distance computing was an original inspiration for development of ARPANET and does still provide a very useful service on Internet. Programmers can maintain accounts on distant, powerful computers, execute programs. File transfer service allows Internet users to access remote machines and retrieve programs, data or text.

One of the most common problems all Internet users face is the fact that it can be quite difficult to find what you want on the Internet. There is no central “main menu” that users can access to navigate through the Internet. Although there might not be an official menu, there are several resources available – both on-line and off-line – that can make “surfing the net” easier. The Internet is a terrific resource. It contains hundreds of web sites dedicated to thousands of topics. There are some web sites, which are used to search information on the web.
We can roughly separate internet applications into the following types: online media, online information search, online communications, online communities, online entertainment, e-business, online finance and other applications.
+
This searching on the web, moving from page to page, website to website in search of information is known as web browsing.
The internet is treated as one of the biggest invention. It has a large number of uses..
+
There is one main software/application which is mainly used for the web browsing, called web browser . There are different types of web browser.
 +
Search services on the Internet come in two main flavours:
 +
1) ‘search engine’ that index words or terms in Internet documents; and
 +
2) ‘directories’ that classify Web documents or locations into an arbitrary subject classification scheme or taxonomy.  
 +
Most search engines take one or more words entered by the user, search the contents of every Web page stored in their databases and display the result. Search engines tend to “index” (record by word) all of the terms on a given Web document.  
 +
Internet directories are on-line Web sites that place Web page into one or more categories. Web pages are usually listed with a brief description and their URL.Directories operate on a different principle. They require people to view the individual Web site and determine its placement into a subject classification scheme or taxonomy. Once done, certain keywords associated with those sites can be used for searching the directory’s data banks to find Web sites of interest some popular search engineers are:-
  
1. Communication

• Google- http://www.google.com
  
2. Job searches

A web browser is an interface that helps a computer user gain access to all the content that is on the Internet and the hard disk of the computer. It can view images, text documents, audio and video files, games, etc. More than one web browser can also be installed on a single computer. The user can navigate through files, folders and websites with the help of a browser. When the browser is used for browsing web pages, the pages may contain certain links which can be opened in a new browser. Multiple tabs and windows of the same browser can also be opened.There are four leading web browsers: Explorer, FireFox, Netscape and Safari but there are many others browsers available.

'''1. Communication:'''
+
 
+
Email is an important communications service available on the Internet. The concept of sending electronic text messages between parties in a way analogous to mailing letters or memos predates the creation of the Internet. Pictures, documents and other files are sent as email attachments. Emails can be cc-ed to multiple email addresses

+
 
+
'''2. Data Transfer:'''
+
 
   
 
   
File sharing is an example of transferring large amounts of data across the Internet. A computer file can be emailed to customers, colleagues and friends as an attachment. It can be uploaded to a website or FTP server for easy download by others. Some of the example of file sharing are:-
+
• FTP
+
'''Safari'''
• TELNET( Remote Computing)
+
Safari is a web browser developed by Apple Inc. and included in Mac OS X. It was first released as a public beta in January 2003. Safari has very good support for latest technologies like XHTML, CSS2 etc.  
Telnet or remote computing is telecommunication utility software, which uses available telecommunication facility and allows you become a user on a remote computer. Once you gain access to remote computer, you can use it for the intended purpose. The TELNET works in a very step by step procedure. The commands typed on the client computer are sent to the local Internet Service Provider (ISP), and then from the ISP to the remote computer that you have gained access. Most of the ISP provides facility to TELENET into your own account from another city and check your e-mail while you are traveling or away on business.  
+
 +
 +
'''Firefox'''
 +
Firefox is a new browser derived from Mozilla. It was released in 2004 and has grown to be the second most popular browser on the Internet.  
  
The following steps are required for a TELNET session
 
  
• Start up the TELNET program
+
'''Opera'''
 +
Opera is smaller and faster than most other browsers, yet it is full- featured. Fast, user-friendly, with keyboard interface, multiple windows, zoom functions, and more. Java and non Java-enabled versions available. Ideal for newcomers to the Internet, school children, handicap and as a front-end for CD-Rom and kiosks.
 +
 
  
• Give the TELNET program an address to connect (some really nifty TELNET packages allow you to combine steps 1 and 2 into one simple step)
+
'''Google Chrome '''
 
+
This web browser was developed by Google. Its beta and commercial versions were released in September 2008 for Microsoft Windows. It has soon become the fourth-most widely used web browser with a market share of 1.23%. The browser versions for Mac OS X are under development. The browser options are very similar to that of Safari, the settings locations are similar to Internet Explorer 7, and the window design is based on Windows Vista.  
• Make a note of what the “escape character” is

+
• Log in to the remote computer,
+
 
+
• Set the “terminal emulation”
+
 
+
• Play around on the remote computer, and

'''3. Information:'''
+
+
Many people use the terms Internet and World Wide Web, or just the Web, interchangeably, but the two terms are not synonymous. The World Wide Web is a global set of documents, images and other resources, logically interrelated by hyperlinks and referenced with Uniform Resource Identifiers (URIs). Hypertext Transfer Protocol (HTTP) is the main access protocol of the World Wide Web, but it is only one of the hundreds of communication protocols used on the Internet.
+
Internet is interconnection of large number of heterogeneous computer networks all over the world that can share information back and forth. These interconnected network exchange information by using same standards and protocols.
