INTERNET TOOLS
Some of the important and popular tools on the Net are discussed
below.These include:
1) Information retrieval tools (ftp and Gopher)
2)Communications tools (E-mail,telnet,Usenet)
3)Multimedia Information tools (World Wide Web)
4)Information search tools (WAIS, Archie,Veronica)
Some of them are discussed below:
Information retrieval tool
ftp
File transfer protocol (ftp) which was one of the first tools on the Internet,allows users to move files,such as text,graphics,sound and so on,from one computer to another.It is a command that activates a type of client server relationship.FTP works as follows: The user first uses the software on his or her machine(or service provider), called the client,to gain access to the remote computer,to either upload,or send to the remote computer or download(receive) certain requested files from it.
Another popular way to retrieve files is by using what is called an anonymous ftp server.In this case,the user logs on to the server using the special user ID anonymous.If the server then asks for a password,the user types in his or her user ID.Freeware and shareware programs that are available at no cost on the Net can be obtained through anonymous ftp servers.Although it is easy to retrieve the information once the site is located,sometimes it is difficult to locate an ftp site or identify the files available on that site.
Gopher
The second type of information retrieval tool available on the Internet is Gopher, a menu based interface that provides easy access to information residing on special server, called Gopher sites.Although Gopher performs primarily the same tasks as the ftp command, its interface is much more user friendly and it provides additional functions,such as links to other Internet services.By selecting an item on the Gopher menu,users can move,retrieve,or display files from remote sites.The menu also allows users to move from one Gopher site to another,where each site provides different information.The entire Gopherspace (which refers to the interconnected Gopher servers) can be easily expanded by adding more servers.
Communication tools
Communication tools facilitate written communications and in this section
we have three types of communication tools.They are:
1)E-mail
2)Telnet
