Introduction of the Internet:
The Internet is the foremost important tool and useful resource for any person. It connects millions of millions of computers, smartphones, web pages, servers, etc. It connects with our daily life scenarios and actions. Whatever you think in this digital era, is just by the Internet. The use of the Internet makes our life easy, fast, and simple. There are plenty of Internet examples that make our daily life simple and fast.
Nowadays, we can send emails, photos, videos, documents, and messages on the Internet with a single click. Internet connects private as well as public purposes. By the use of this, get all worldwide information. No anywhere needs to go. All electronics systems, computers are operated by the use of the Internet. So we can say that this DIGITAL world correlates with the Internet. If the Internet does not exist, then DIGITAL has no meaning. There are plenty of examples (almost all) that use the Internet to send and receive information online due to the Internet.
The Internet that we know and use is not created and invented by a single person. There are so many programmers, scientists, engineers, etc., who developed internet new features and technology. When networking technology was first developed, several scientists and engineers were doing research together to create the ARPANET. Many scientists and engineers contributed to developing the initial part of the Internet, some of them are discussed below:
- Paul Baran (1926-2011): He was one of the main scientists who contributed to the ARPA research. In 1959, he joined an American think tank. He also involved the US air force in developing new technology related to the Internet; after that, Baran proposed a communication network with no central command point.
- Lawrence Roberts (1937-2018): He was the chief scientist at ARPA research work. He had the responsibility to develop computer networks. He began to work on the creation of the distributed network.
- Leonard Kleinrock (1934- ): He had contributed to the creation of the distributed network.
- Donald Davies (1924- 2000): At the same time, this scientist developed similar technology at the National Physical laboratory. He participated very much along with Lawrence Roberts to work and develop in the field of the ARPA research work.
- Bob Kahn (1938- ): Bob Kahn was an American computer scientist who developed TCP/IP, the set of communication protocols that communicate with every network. File Transfer (FTP) is the most important protocol used for file transfer over the network. It uses TCP/IP for communication, and FTP works TCP port 21. It works on the principle of the client-server architecture model. The client sends requests to the server for that particular file.
- Jon Postel (1943- 98): Jon Postel discovered DNS (Domain name System), the Internet's phone book. Domain Name Systems are the most important thing in the computer network fields.
We all depend on the Internet worldwide and want to share data and information. "Domain Name System" (DNS) or we can say that "Domain Name Server" plays an important role in sending data and information through the Internet. DNS is a protocol that specifies how computers exchange data on the Internet. It works on the principle of the TCP/IP protocol suite. Computers and other network devices on the Internet use IP addresses to send and route requests, so DNS manages a massive database that maps domain names into IP addresses. It uses the UDP protocol for transport layer communication.
- Tim Berners-Lee (1955- ): WWW (World Wide Web) is the most important tool to develop the Internet. It is the collection of the websites or web pages stored in web servers and connected to the local computers through the Internet. HTML is the basic source for the creation of web pages. Tim Berners-Lee developed these www features.
The initial creation of the internet
In 1960, the internet first started being developed in California by many scientists and engineers. This was the first meeting in the phase of the development internet, which was held by the NWG (Network Working Group) at the SRI (Stanford Research Institute). These meetings and developed by several scientists such as Elmer Shapiro, Ron Stoughton, Steve Crocker, Steve Carr, and Jeff Rulifson. These are all scientists and engineers trying to develop the internet. They faced many challenges during the invention of the first starting phase of the internet, so they discussed how to resolve problems during the inventions of the internet.
Open for the general public
General persons have learned and knew the features of the internet on July 3, 1969 at (the University Of California, Los Angeles). The main aim was to interact with the internet for all people, how can learn and use the internet easily in the whole world.
First network Equipment
On August 29, 1969, the first time IMP (Interface Message Processor) was the first piece of the network equipment and network switch. These all types of equipment and switch were delivered to “UCLA”.
The first message and network crash
A computer science professor Leonard Kleinrock was sent the first internet message from the laboratory of “UCLA” on October 29, 1969. This was the initial internet backbone. The LO was the first message sent out, and it was an attempt by Charley S. Kline to log onto the SRI computer at UCLA. However, the whole message could not be completed due to the SRI system crashing.
The First time email use and development
Email is the foremost necessary to communicate with each person in modern times. Ray Tomlinson invented the first time email system in 1971. He also developed @ symbol for sending or creating an email. The email was the first communication message delivered across a network to the users. This is the new phase of the invention of the internet.
The development of the TCP/IP
There are some rules and procedures to communicate between client and server to make communication most efficient among devices.
So we can define as- Protocols as the set of rules and regulations that exchange information in an easy, reliable, and secure way among devices. Think of our entire world scenario. There are must some rules and regulations to communicate way easily. Without a protocol, computers and other devices would not know how to send data to each other.TCP/IP protocol is used for remote connections since a computer's IP is unique, so it is used to identify and access remotely to a particular computer.
TCP (Transport Control Protocol) is the most popular network protocol globally and was designed by Vinton Cerf and Robert Kahn in 1973. They help more and more in the development of the internet
First commercial network
Telnet is the first internet service provider founded in 1974 as a version of the ARPANET (Internet Service Provider).Generally, the main task of the internet is to provide services to users. If a user wants to run different application programs remotely, Telnet provides a connection to the remote.
Computer in such a way that a local terminal appears on the remote side. Telnet and FTP both are application layer protocols. Both are also connection-oriented protocols as they create a connection between the remote host and server.
FTP is used to transfer the files from one system to the other, and TELNET is used for remote login for any computer system.
The Modem is introduced
Today, there are so many digital Modem has been developed. For the first time, 80- Dale Hetherington and Denis Hayes developed the 103A type of Modem. The main function of the Modem is to connect to the internet. And by using the internet, we can communicate all over the world easily. It is important for every computer and internet user So that we connect the all over the world.
DNS (Domain Name System) is introduced
“Jon Pastel” and “Paul Mockapetris" is the DNS founder. They invented the DNS system in 1984.We all depend on the full internet worldwide and want to share data and information. "Domain Name System" (DNS) or we can say that "Domain Name Server" plays an important role in sending data and information through the internet.
DNS is a protocol that how computers exchange data on the internet. It works on the principle of the TCP/IP protocol suite.
Computers and other network devices on the internet use IP addresses to send and route requests, so DNS manages a massive database that maps domain names into IP addresses. It uses the UDP protocol for transport layer communication.
