HTTP Client-Server Communication Technology

1.1 – Internet

Computers are connected to each other to send and receive information.

This is called a computer network. The Internet is a network of interconnected networks
This is a network of networks.

What’s this internet that is not the mainstay of sleep technology? In addition to the emergence of education, the 1957 It happened on the 4th day of the month.

That Sputnik 1, the first prototype of the Soviet Union, was released today. I was able to win.

The Great Barrier Reef was released.

For this reason, a pre-technology organization called ARPA (Advanced Research Project Agency)
The Union Solidarity and Development Association (USDO) aims to make education more effective.

It was formed. The Internet is one of ARPA’s creations.

In the 1960s, computer scientist Joseph Licklider called it Man-Computer Symbiosis.

A pre-submitted article was submitted. This article is about computer networks It is a building block for building.

In 1962, Licklider published ARPA Information. In addition to chairing the Process Office, a group was formed to conduct research on network technologies. Yes However, the group quit before the realization of his ambitions.

Some years later, in 1967, he died When it arrives, it is called the ARPANET.A computer network technology has been introduced. December 1969. The first four computers were connected to the network. That first the Packets switching method used on the network is still in use.

ARPANET Pack Packets Switching TechnologyJANET, a technology company Other organizations, including this one, CompuServe they are also used.

There is water. Networks are connected to each other due to different techniques and practical details of the same basic technology.But with good credit, you might find exactly what you need.

ARPA’s Satellite to help solve this problem. Robert Kahn of the Network Packets Project and Vint Cerf of Stanford University. Create a protocol that can act as an intermediate mask for the same network system. I gave it.

Published in December 1974.This technology was called “Internet Transmission Control”. As a result, networks are able to connect to each other.

ARPA also developed the necessary companion software, and in 1977 a different network was created.
We were able to successfully connect three of them.

In 1981, “Telecommunication Protocol / The Internet Protocol (TCP / IP) ” was introduced in 1982.
By the time TCP / IP arrived, other organizations were also starting to use it.

The whole world Internet Network. Yes. In 2016, not only computers but also computers were on the Internet. Mobile Phone Up to 22.9 billion devices are connected to tablets and other devices.

2020 It is estimated that there will be 50.1 billion connected devices on the Internet by this time. It says one thing.

Here, the Internet is connected to computers and other devices by means of sleep. It can be known as technology.

For more information, please contact: This Develops Internet-based technologies such as the World Wide Web, Email, and more.

Of course. Email and World Wide Web Pre-Information. It can be known as the “road” that flows through these gaps.

Like the World Wide Web and Email, you can stream information on the Internet. There are other technologies as well. Instant Messaging (IM), Internet Relay Chat (IRC), Voice Over Internet Protocol (VoIP), Secure Shell (SSH), File Transfer Protocol (FTP). Yes.

1.2 – World Wide Web (WWW)

Around the 1990s, an Internet network known as Gopher was used to search for information. A system that can be used as a spinner is being introduced.

In University , There are so many types it’s hard to say It’s a technology used.

You can store all your data in one place. Gopher system allows computers to communicate with each other.

Gopher Technology’s University of Minnesota’s February 1993. A pre-release statement was issued regarding the changes. Pre-users of Gopher technology, It’s just a matter of time before we start using it.

For this reason, use the current Gopher technology. People are starting to think about switching to a different technology.

At the time, it was called CERN ( The European Council of Nuclear Research Center ) in Switzerland. The organization has a technology that can replace Gopher.

CERN is a computer Scientist (Sir) Tim Berners-Lee Presents Other Documents Inside Documents. A reference technology has been created in advance.

This is called a hypertext document. For practical use. With server software that can print documents
He also created a client program called a browser that can retrieve documents.

They put together all the creations and named it ” World Wide Web “.

Tim Berners-Lee, 1993 Source code for World Wide Web technology released on April 13th. It was made available to the public. As a result, not everyone is convinced that the technology is free. Inventing related technologies I was able to win. This too, is rarely a turn for the worse.

It’s a decision. In that year, the National Union of Superior (NCSA) was formed. You can preview hypertext documents in computing apps and continue to use Gopher.

I created a browser program in advance. It was called Mosaic. Unix Operating System. It was created to be used in December 1993 version for Mac and Windows. I was able to spread the word in advance.

Mosaic and WorldWideWeb have been around since then It became clear. Browsers like Mosaic have been added one by one.

Most of them are university students and so on Corporate research projects have become involved.

In the past, it was called the Web – The World Wide Web, for short, conveys information on the Internet. It has become one of the most important technologies available. Web technology has three main components.
