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.
