What is Internet? it's history and how it affect our lives.

What is Internet?

         

            The internet in simple terms is a network of the interlinked computer networking worldwide, which is accessible to the general public. These interconnected computers work by transmitting data through a special type of packet switching which is known as the IP or the internet protocol.

Internet is such a huge network of several different interlinked networks relating to the business, government, academic, and even smaller domestic networks, therefore internet is known as the network of all the other networks. These networks enable the internet to be used for various important functions which include the several means of communications like the file transfer, the online chat and even the sharing of the documents and web sites on the WWW, or the World Wide Web. 

It is always mistaken said that the internet and the World Wide Web are both the same terms, or are synonymous. Actually there is a very significant difference between the two which has to be clear to understand both the terms. The internet and World Wide Web are both the networks yet; the internet is the network of the several different computers which are connected through the linkage of the accessories like the copper wires, the fiber optics and even the latest wireless connections. However, the World Wide Web consists of the interlinked collection of the information and documents which are taken as the resource by the general public. These are then linked by the website URLs and the hyperlinks. Therefore World Wide Web is one of the services offered by the whole complicated and huge network of the internet. 

The use of IP in the Internet is the integral part of the network, as they provide the services of the internet, through different layers organization through the IP data packets. There are other protocols that are the sub-classes of the IP itself, like the TCP, and the HTTP. 

How does Internet affect's our lives?

          Internet is undoubtedly the most crucial technology of the modern world, the useful application has not only made our lives easier than ever before but it also plays a very important role in the future developments.

Everyone is of course very well known that internet has the global advantages than just a few concentrated ones. With the introduction of the internet the global communication has become a matter of just the finger tips of the users. The internet has brought about the various different, innovative communication means like the emailing, chatting, and the voice conversation system over the internet. 

These systems have not only made the communication easy but also the daily lives interactions following the business of people living on the other sides of the world. The other blessings of the internet include the umpteen resources that we can get on anything at all over the net and also the entertainment via the games, websites, and media access which was never so easy before. 

Everything has the negative aspect to it and so does the internet, the biggest threat of the internet is in the pornography and the security threats. Pornography is widespread over the internet making it inappropriate to be used by the children below certain age so as to prevent the psychological damage from the early days. These sites are easily accessible and attractive for the teenagers and young kids. 

The security over the internet cannot be guaranteed due to the major hacking techniques and theories, even the interaction between the two strangers can lead to friendship and then serious cases of murders and serial killers plots which have become increasingly popular because of the internet launch. 

Despite of a few major problems the Advantages of the Internet use clearly outweigh the few disadvantages.

History of Internet

                   The history of the Internet began with the development of electronic computers in the 1950s. The public was first introduced to the Internet when a message was sent from computer science Professor Leonard Kleinrock's laboratory at University of California, Los Angeles (UCLA), after the second piece of network equipment was installed at Stanford Research Institute (SRI). This connection not only enabled the first transmission to be made, but is also considered to be the first Internet backbone. This began the point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks.

In 1982, the Internet protocol suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced. Access to the ARPANET was expanded in 1981 when the National Science Foundation (NSF) developed the Computer Science Network (CSNET) and again in 1986 when NSFNET provided access to supercomputer sites in the United States from research and education organizations. Commercial Internet service providers (ISPs) began to emerge in the late 1980s and early 1990s. The ARPANET was decommissioned in 1990. The Internet was commercialized in 1995 when NSFNET was decommissioned, removing the last restrictions on the use of the Internet to carry commercial traffic.

Since the mid-1990s, the Internet has had a revolutionary impact on culture and commerce, including the rise of near-instant communication by electronic mail, instant messaging, Voice over Internet Protocol (VoIP) "phone calls", two-way interactive video calls, and the World Wide Web with its discussion forums, blogs, social networking, and online shopping sites. The research and education community continues to develop and use advanced networks such as NSF's very high speed Backbone Network Service (vBNS), Internet2, and National LambdaRail. Increasing amounts of data are transmitted at higher and higher speeds over fiber optic networks operating at 1-Gbit/s, 10-Gbit/s, or more. The Internet continues to grow, driven by ever greater amounts of online information and knowledge, commerce, entertainment, and social networking.
