INTERNET IS A BOON OR CURSE....!!!
INTERNET:-
Now in these days, the internet has achieved billions of its user. Life without the internet is incomplete for many people and why it is not so while it is used to fulfill thousands of needs in day-to-day life. It is a daily need material almost for everyone. Internet is a global wide-area network that connects computers all over the globe and allowing for electronic communication. A publicly accessible system of networks that connects computers on the globe through TCP/IP protocol. Worldwide wide the number of Internet users drastically increased from 413 million to 3.4 billion in 2000 to 2016.
THE HISTORY OF INTERNET:-
"Necessity is the mother of discovery'' The story of the Internet has started in the 1960s in the American defense sector. Initially, it is known as ARPANET.
In 1971 due to an increase in computer technology internet has become a network of approx 10 thousand computers. Long before the technology existed to actually build the internet, many scientists had already anticipated the existence of worldwide networks of information. Nikola Tesla toyed with the idea of a “world wireless system” in the early 1900s, and visionary thinkers like Paul Otlet and Vannevar Bush conceived of mechanized, searchable storage systems of books and media in the 1930s and 1940s. The first workable prototype of the Internet came in the late 1960s with the creation of ARPANET, or the Advanced Research Projects Agency Network. Originally funded by the U.S. Department of Defense, ARPANET used packet switching to allow multiple computers to communicate on a single network.
On October 29, 1969, ARPAnet delivered its first message: a “node-to-node” communication from one computer to another. (The first computer was located in a research lab at UCLA and the second was at Stanford; each one was the size of a small house.) The message—“LOGIN”—was short and simple, but it crashed the fledgling ARPA network anyway: The Stanford computer only received the note’s first two letters.
THE PRESENT INTERNET TECHNOLOGIES:-
Internet Technologies is a technical field that covers the necessary skills to develop applications on the Internet or Internet-based systems, harnessing e-commerce, cloud, mobile, and Web-based technologies.
The worldwide web:- While the Internet provided powerful capabilities in such utilities as telnet and FTP, it was not particularly easy to use. This began to change in 1993 when researchers at CERN in Switzerland developed a means of sharing data using hypertext, where codes in the document being examined allowed users to jump to another document merely by clicking on a hyperlink. FTP and telnet capability were added so that they could also be invoked merely by clicking on a hyperlink. This type of program became known as a browser and while the CERN browser was limited to text documents, a team at the University of Illinois at Urbana-Champaign (specifically the National Center for Supercomputer Applications – NCSA) developed a more powerful browser called Mosaic which allowed for the inclusion of graphics. Mosaic was freely available and led to a huge increase in the use of the Internet and WWW. Some of those involved in the development of Mosaic helped form Netscape Corporation, which has developed commercial versions of both browsers and servers.
ISO MODEL:- The International Standards Organization (ISO), based in Geneva Switzerland, is composed of groups for various countries that set standards working towards the establishment of worldwide standards for communication and data exchange. One notable accomplishment has been the development of a reference model that contains specifications for a network architecture for connecting dissimilar computers, with the main goal being that of producing an open and non-proprietary method of data communication. This reference model, called the Open Systems Interconnect Reference Model (OSI RM), was developed in 1981 (?) and revised in 1984. The OSI RM uses 7 layers, each independent of the other, to allow computers to exchange data. To transfer a message from user A to user B, the data has to pass through the 7 layers on the user's A machine, before being transmitted through the selected medium. At the receiving computer of user B, the data must then pass through the 7 layers again, this time in reverse sequence, before being received by user B. For data to be transferred, it must pass through all 7 layers on both computers. Each layer follows a relatively strict specification and this allows the different layers to be produced and implemented by different concerns. Each layer can then interface with its neighboring layers even though they may have been developed by different groups. One way of viewing the activities of the layers is that as the original message passes down the layers towards the medium on the computer of user A, additional information, for both formattings or addressing information, is added to the beginning or end message. The additional information is added to ensure correct communication. At the other end (i.e. at user B) this information is gradually stripped off as the data passes through the 7 layers - this time in reverse order. The layers are arranged in order as follows: Layer 7, Application Layer. This layer defines network applications such as error recovery, flow control, and network access. Note that user applications are not part of the layers. Layer 6, Presentation Layer. This layer determines the format used to exchange data in such aspects as data translation, encryption, and protocol conversion. The data from user A is translated to a common syntax that can be understood by user B. In this way, it specifies how applications can connect to the network and to user B. Layer 5, Session Layer. This layer controls the communication session between computers. It is responsible for establishing and removing communication sessions between computers. Additional address translations and security are also performed. This layer, therefore, instigates a data transfer session between user A and user B so that an extended data transfer can take place. Layer 4, Transport Layer. This layer is responsible for ensuring that data is delivered free of error and provides some flow control. This layer ensures that data is transferred as part of the session instigated by the Session Layer. Layer 3, Network Layer. This layer handles the delivery of data by determining the route for the information to follow. The data is divided into packets with addressing information attached. It also translates addresses from names into numbers. Intermediate addresses are also attached. Layer 2, Data Link Layer. This layer defines the network control mechanism and prepares the packets for transmission. Layer 1, Physical Layer. This layer is concerned with the transmission of binary data between stations and defines the connections. The connection definition includes such aspects as mechanical, electrical,, topology, and bandwidth aspects.
Various prognoses forecast that the number of connected devices could exceed the 20 billion mark as early as next year and could reach 50 billion by 2022. Even today, there are possibly already more connected devices on the planet than there are people.
The first major thesis of the Digital Life in 2025 report is that “information sharing over the Internet will be so effortlessly interwoven into daily life that it will become invisible, flowing like electricity, often through machine intermediaries.” The Internet of Things/Everything will be the biggest driver. one of the most dynamic and exciting developments in information and communications technology is the advent of the Internet of Things (IoT). Although networking technologies have become increasingly ubiquitous over the past two decades, until recently they have largely been restricted to connecting traditional end-user devices, such as mainframes, desktop and laptop computers, and, more recently, smartphones and tablets.
In 2030, the internet will be underwater. Granted, a lot of the internet is already underwater—traveling through fiber-optic cables that transport almost all transoceanic traffic. And cables will still be the foundation of the global internet in 2030.
In 50 years, internet users will be nearly as pervasive and necessary as oxygen. Seamless connectivity will be the norm, and it may be impossible to unplug.
Fifty years after the first computer network was connected, most experts say digital life will mostly change humans’ existence for the better over the next 50 years. However, they warn this will happen only if people embrace reforms allowing better cooperation, security, basic rights, and economic fairness.
involved will replace the internet. Everyone on the planet In 100 years, it's highly likely something new and many more will be networked. Homes, cars, businesses, even our bodies will be instrumented and monitored. Augmented reality will become normal.
Today’s modern & tech-savvy world is very dynamic. Every day brings new scientific discoveries and advancements in internet technologies. All these new technologies can radically change a person’s life if used well. In simple words, Internet technology stands for a variety of technologies and services that are used in modern communication protocols over the global internet. Today, in this post, we will talk about the Top 7 Breakthroughs in Internet Technologies That Will Change the World forever. So, let’s start the journey now.
ADVANTAGES OF INTERNET:-

An Internet connection offers many people an option to create a virtual office by allowing them to work from home.
8.Internet of Things
The Internet makes smarter your device in your home and giving them access to the Internet. For instance, to control the heating and cooling in your home, the Nest thermostat can connect to the Internet. When devices have been connected to the Internet, they can be controlled remotely with the help of your smartphone or computer.
DISADVANTAGES OF INTERNET:-
1. Addiction, time-waster, and causes distractions
If any person is spending much time on Internet-connected devices, he can be addicted to the Internet. An Internet addictive person can lead to spending his precious time on the Internet, rather than doing something productive. Thus, anyone who is addicted to surfing the Internet can hamper workplace productivity as well.

7. Health issues and obesity
If you are surfing the Internet frequently, playing games, and spending too much time on the computer, it can also lead to obesity and an unhealthy lifestyle. Also, a person who spends too much time on the computer can face a problem like carpal tunnel syndrome as a computer requires a lot of repetitive movement.
You are required to move your body parts to operate the computer, for example, typing and moving your hand to the mouse are repetitive actions that can cause injuries. Understanding computer ergonomics, keeping the proper posture, and taking breaks can all help delay or prevent these injuries.

8. Depression, loneliness, and social isolation
The Internet also becomes a reason that leads to depression as many people tend to compare their lives with others on social networking sites. Social networking sites provide users the option to make thousands of friends and communicate with each other. There are also available online games that allow players to communicate with others. Although social networking sites can give you the benefits to find new connections all over the world, you may find yourself disconnected from your real-life friends.
