Internet
Exploring Its Impact and Applications



What is Internet?

The Internet is a vast network that connects computers all over the world. Through the Internet, people can share information and communicate from anywhere with an Internet connection.

The Internet is a global network of billions of computers and other electronic devices.


History of Internet

In the late 1960s, with the creation of the Advanced Research Projects Agency Network, which was funded by the U.S. Department of Defense, the “first workable prototype of the Internet” was born.

The internet began as ARPANET, an academic research network that was funded by the military's Advanced Research Projects Agency (ARPA, now DARPA).


Basic Services of Internet

  • Electronic Mail

  • FTP ( File Transfer Protocol )

  • Telnet

  • The world wide web


Electronic Mail

Electronic mail (e-mail) is a computer-based application for the exchange of messages between users.

A worldwide e-mail network allows people to exchange e-mail messages very quickly. E-mail is the electronic equivalent of a letter, but with advantages in timeliness and flexibility.


FTP ( File Transfer Protocol )

FTP (File Transfer Protocol) is a standard network protocol used for the transfer of files from one host to another over a TCP-based network, such as the Internet. FTP works by opening two connections that link the computers trying to communicate with each other.

Telnet

Telnet (short for "telecommunications network") is a client/server application protocol that provides access to virtual terminals of remote systems on local area networks or the Internet. It is a protocol for bidirectional 8-bit communications.

It was originally developed as a character-oriented terminal emulation protocol used in the UNIX environment.


The World Wide Web

World-Wide Web (also called WWW or W3) is a hypertext-based information system. Any word in a hypertext document can be specified as a pointer to a different hypertext document where more information pertaining to that word can be found.


Uses of Internet

  • Communication

  • Information Access

  • Entertainment

  • E-Commerce and Online Banking

  • Cloud Storage and File Sharing

  • Research and Innovation

  • Government Services and E-Government


Disadvantages Of The Internet

  • Addiction and Overuse

  • Spread of Misinformation

  • Digital Divide

  • Environmental Impact
