WHAT IS INTERNET

Hey Friends Today, We talk about the internet, everyone wants to know what is internet but many sites do not explain accurately ......     But not worry now I am here your technical bhai clear your every doubt regarding internet query......

What Is the Internet?

The Internet is a global network of billions of computers and other electronic devices. With the Internet, it's possible to access almost any information, communicate with anyone else in the world, and so much more.

You can do all of this by connecting a computer to the Internet, which is also challenging online. When someone says a computer is online, it's just another way of saying it's connected to the Internet

Who Created the Internet?

According to Hobbes' Internet Timeline, in 1957, the Soviet Union launched the first satellite into orbit. While this might not sound serious, this happened during a time in American history called the Cold War. It was at this time the threat of nuclear war was at its greatest. The thought was, if the Soviets could launch a satellite into space, then they might be able to launch a nuclear bomb and hit the United States, destroying all of our communication lines.

The Internet began in 1969 as a research project funded by the Department of Defense with a goal of creating a means of communication besides telephone lines. The first network was called ARPANET (Advanced Research Project Agency NETwork). The focus was on communicating in the event part of the network was disabled. This early network was the precursor to the Internet. It was limited in function but launched the idea of a different method of communication.

What is the Web?

The World Wide Web—usually called the Web for short—is a collection of different websites you can access through the Internet. A website is made up of related text, images, and other resources. Websites can resemble other forms of media—like newspaper articles or television programs—or they can be interactive in a way that's unique to computers.

The purpose of a website can be almost anything: a new platform, an advertisement, an online library, a forum for sharing images, or an educational site like us!

How Does Information Move Across the Internet?

Information moves across the Internet much like UPS delivers packages. When you order something, it could be boxed in multiple packages because one box would be too large to deliver. A message or webpage is broken down into packets to be delivered to your computer. Each packet has to address information so that it knows where it is going. Your message or webpage could be broken down into many packets and each packet will have the address and the number of the packet so that when it gets to its final destination your computer or email server will know how to put the packet together to make a meaningful message.

In the beginning, most information moved across telephone lines using a modem and dial-up connection. This method of connection, slow and unreliable, is still available. Today, though, we have connections, such as ISDN - Integrated Service Digital Network, DSL - Digital Subscriber Line, T1 and T3 lines, that provide faster speeds. You can also get the Internet over your local cable TV lines and by satellite. No matter how you pay for your package.

History of Internet?

This marvelous tool has quite a history that holds its roots in the cold war scenario. A need was realized to connect the top universities in the United States so that they can share all the research data without having too much of a time lag. This attempt was a result of Advanced Research Projects Agency (ARPA) which was formed at the end of the 1950s just after the Russians had climbed the space era with the launch of Sputnik. After the ARPA got success in 1969, it didn’t take the experts long to understand that how much potential can this interconnection tool have. In 1971 Ray Tomlinson made a system to send electronic mail. This was a big step in the making as this opened gateways for remote computer accessing i.e. telnet.

 

During all this time, rigorous paperwork was being done in all the elite research institutions. From giving every computer an address to set out the rules, everything was getting pinned down. 1973 saw the preparations for the vital TCP/IP and Ethernet services. At the end of the 1970s, Usenet groups had surfaced up. By the time the 80s had started, IBM came up with its PC based on Intel 8088 processor which was widely used by students and universities for it solved the purpose of easy computing. By 1982, the Defence Agencies made the TCP/IP compulsory and the term “internet” was coined. The domain name services arrived in the year 1984 which is also the time around which various internet-based marked their debut. As the internet was coming out of its incubation period which was almost two and a half decades long, the world saw the first glitch that was not at all a part of the planned strategy. A worm, or a rust the computers, attacked in 1988 and disabled over 10% of the computer systems all over the world. While most of the researchers regarded it as an opportunity to enhance computing as it was still in its juvenile phase, quite a number of computer companies became interested in dissecting the cores of the malware which resulted in the formation Computer Emergency Rescue Team (CERT). Soon after the world got over with the computer worm, World Wide Web came into existence. Discovered by Tim Berners-Lee, World Wide Web was seen as a service to connect documents in websites using hyperlinks.

 

By the time the 90s arrived, the larvae had started coming out as more than 40million computers had been sold out, an antivirus had already been launched as well as the graphical user interface was quite in its evolution. “Archie”, the first internet search marked the beginning of a new era in internet computing. Categorizing the websites was in its most dynamic phase as commercialized email websites were getting on day by day. It was during this time that the term “spam” was coined which referred to fake emails or hoaxes. Read more about email and email working. In 1992, internet browser called “Mosaic” came into existence. One of the very popular internet browsers, Netscape Navigator made its debut in 1994 which ultimately went to compete with Microsoft’s Internet Explorer. By this time the domain name registration had started to get exponential and was made commercial. In short, the Internet Explosion had started to occur.

 

Coming years saw the launch of giants such as Google, Yahoo as well as a strengthening of ultimate revolution creators i.e. Microsoft, Google, IBM etc.
