There are problems caused by the Internet society.

For example,

・cyberbullying

・spoofing

・texting on the job

・Internet fraud / online scam(s)

・leak of personal information

The Internet originated in the 1969 ARPANET experiment by the US Department of Defense Advanced Research Projects Agency ARPA (now DARPA). ARPANET experiments have demonstrated that packet switching technology is effective for data communication and that data communication on a global scale can be achieved by standardizing the protocol (TCP / IP).

In the mid-1980s, the National Science Foundation (NSF) began supporting the project. In 1990, the original ARPANET was dismantled and led by the NSF network operated by NSF, and LAN servers of research facilities in the world including the United States were connected to this network. Later, this network was opened to commercial networks and developed rapidly.

The Internet is connected to the whole world. However, unfortunately, in Japan, I still feel that the benefits of globality are not often used.

Many artists have the ambition to ultimately want to be active in the world.

But in order to make it happen, it must be known in the world. To put it the other way around, increasing awareness in the world means that opportunities for overseas activities are greatly expanded.

However, before the advent of the Internet, delivering information overseas was a daunting skill. Even if there was a connection with overseas media, the space for publishing was limited, and it was almost impossible to publish unless there was much topicality.

But, now is the age of the Internet. If you look at the sites of the world, there are many sites that handle music information. At the same time, it is also segmented by genre, so you can choose the media according to the musicality and user target.

So how do you approach it? This is not really difficult. When publishing information, it will be the key to success to put together an easy-to-understand catch and information about what kind of music it is. Of course, translation into the language of each country is necessary, but it is easier to transmit simple words that appeal to emotions than using difficult grammar.

Now, as usual, we collect information on the Internet and write a recent report on Facebook, but it has only been about 20 years since we were able to do this.

Let’s explain how a convenient network works so easily, and how it works.

First, the computer is not connected to the network. This is called standalone. It sounds lonely.

Another computer came here, and a network was first created to communicate one-on-one. This is called peer-to-peer. Peer has the meaning of a colleague, a friend. It is an equal translation.

However, when the number of computers increases and you try to communicate with multiple computers, peer-to-peer alone can reveal the limit. Therefore, it divided the role of computer into client (user) and server (service person) and decided to use one powerful server from multiple computers at the same time. This is a client / server network.

In addition, as computers have grown, networks and networks have become interconnected. It will connect computers around the world like a web. That’s the Internet.

In the Internet, data is transmitted by multiple routes. The data is relayed and sent to various servers regardless of which server it passes through.

For example, when you try to access “google.com” from your home computer, you will first access a machine called your router at home via your computer, WiFi (LAN) or LAN cable.

A router connects to the provider’s server you contracted through optical and other digital lines. First of all, ask “Where is google.com?” A string like “google.com” that you enter in the browser’s address field is a name called “domain name.” This is the name of a computer somewhere in the world. However, the name does not know where on the Internet the computer is actually located, so first ask “Where does this domain point?”. Every provider has a server for domain queries. It is called DNS (domain, network, server).

However, since various people connect and disconnect from the new computer every day on the Internet, the DNS of the contracted provider does not necessarily know “google.com”. In that case, the DNS asks other DNSs “Do you know this domain?”

If a place is found successfully, four numbers will be returned. These four numbers are called “IP address”. An IP address is a specific address of a computer. IP stands for “Internet Protocol” and is a number that indicates only one place in the world.

Once you know this number, you can send any information you like. Information is sent in chunks called “packets”. If you specify the IP address acquired earlier in this “packet” as the “destination” and pass it to the server, it will be delivered to the target computer using the bucket brigade method.

Even when searching casually, so much movement is happening. It may be a bit surprising.
