  1. The Internet- A Boon or A Curse? Presentation Made By- Joy Oberoi

  2. Introduction The Internet is commonly known as a ‘network of networks’ that consists of many private, public, academic, business and government networks. It can also be defined as a worldwide interconnection of computers and networks that facilitate the sharing of information among users. These networks are linked by a broad array of electronic, wireless and optical networking technologies. The Internet is used by everybody in the world. Thus, it comes under all the Areas of Impact

  3. I.T. Components- Functioning of the Internet Each computer connected to the Internet, must have an unique address. Internet addresses are in the form of ‘nnn.nnn.nnn.nnn’ where ‘nnn’ stands for any number between 0-255. This unique address is known as the IP Address. For example, 192.168.1.1 is an IP address. If one connects to the Internet through an ISP (Internet Service Provider), then he/she is usually assigned a temporary IP address for the duration of the dial-up session. Whereas, if one connects through LAN (Local Area Network) then it might have a permanent IP address.

  4. How does communication take place over the Internet? When a message from one computer needs to be transmitted to another, it makes use of a Protocol Stack. Every computer needs a protocol stack to communicate with others over the Internet. The stack comes built into the operating system. The protocol stack that is used on the Internet is known as the TCP/IP. This is because two major communication protocols are used.

  5. If the message that is sent from one computer to another is large, then it is broken down into smaller parts. These parts are known as Packets. These packets go through the application layer towards the TCP layer and each one of them is given a Port Number. Once it passes the TCP layer, it enter the IP layer where it receives it’s destination address. Thereafter, the hardware layer converts alphabetical characters to electronic signals and transmits them over the phone lines.

  6. On the other end of the phone line, the ISP has a direct connection to the Internet. The ISP’s router firstly examines the destination address on each packet and then determines where to send it. After reaching the destination, as the packets move upwards, all the routing data that had been added to the packets by the stack, is removed. By the time the packets reach the top of the stack, they are re-assembled .

  7. The ISP maintains a pool of modems for their dial-in customers. This Modem Pool is usually managed by a dedicated computer, which controls data flow from the pool to the ISP Backbone. Billing and usage details are collected here as well.

  8. The Internet- Boon or Curse? In the field of education, the Internet is considered no less than a boon for a child’s education. Retrieving audio-visual information from the Internet makes classes more interesting and thus students are more motivated towards learning. In the long run, it help students develop certain skills such as independent learning, easily gain access to online resources etc.. Also, the Internet continues to expand its resources and provide students with information that is not available in print. These could reports on governmental and non-governmental organizations, scientific reports and artistic resources. The Internet is also made to use when it comes to communication. The ability to send information by the click of a button, talk to people across the globe etc. has all been given to the users by the Internet. Worldwide, teachers also consider the Internet to be a great tool which would help them in curriculum development by incorporating internet-based activities. Career Planning is another major benefit of using the Internet. Finding information on courses, prospects etc. gives one an insight as to what career options are available and helps in making decisions in advance. Executing online transactions helps save time and aids some in learning new ways of carrying out their chores.

  9. All the teenagers spend every possible moment on the Internet playing games, or chatting with friends. This results in their mind diverting from studies. Thus, they end up getting a poor grade. Some might indulge in illegal activities such as downloading illegal software, hacking or sending out viruses over the Internet. Whilst doing so, they might unintentionally violate laws and get into trouble. Even though the Internet is considered a treasure of information, not all of what is available, is reliable. The Internet also exposes people, especially young children, to inaccurate information which might lead to misinterpretation of facts and unwise judgments. Getting addicted to the Internet is another major problem. This leads to loss in concentration and lack of physical activity, which in the long run, affects the health of people.
