What the Internet is and how it works

A short history of the internet

  • This interesting story has its roots in 1969 , starting with an agency, DARPA, which began collaborating with some top universities. The network was small, between several universities and was called ARPANET .
  • In 1971 the email appeared and it was decided to use the @ symbol to separate the domain username. At the same time, the Gutenberg project appeared, which aims to create an electronic library.
  • In 1973, the first transatlantic connection took place, attracting a university from London.
  • In 1977, with the advent of the first modern computer, there was a revolution in this regard, being the beginning of the development of Internet networks.
  • In 1982 also appears the first emoticon , very simple :-), which will then develop into the forms you know today.
  • Already from 1987 to 1988, the Internet is growing, from 1000 hosts at the beginning, to over 30,000, and ICR appears which will develop and allow the creation of real-time chat applications and messaging programs .
  • In 1989, the World Wide Web proposal appeared, for the first time , very well known today, with the abbreviation www.
  • In 1991, the first web page appeared. At the same time, the MP3 format is standardized and the first webcam appears.
  • Since 1995 we can talk about the internet at a macro level, being the beginning of its commercialization.
  • Google also appeared in 1998, changing the way it searched the Internet.

And from here things start to flow, reaching the shape you know today.

But certainly things will not stop here, but will continue to evolve and maybe I still do not dream of what can be achieved.

What types of computer networks are there?

We've been talking about what the Internet is about computer networks, and here are some terms you've probably heard of, but you may not know exactly what it means:

  • LAN – is a small internet network, for a company, a building or even an apartment and comes from Local Area Connection;
  • MAN – refers to a medium-sized network, which may include a city or only a part, the Metropolitan Area Network;
  • WAN – is a large Internet network, which can include a country or a portion, the term coming from Wide Area Connection.

If you are interested in more details in this regard you can search for computer networks of papers or other publications.

How does the internet work?

In order to provide more information about the internet, we need to go a little deeper into how it works.

All equipment connected to the Internet, whether it is mobile phones, computers, tablets, etc., communicates through protocols , which are sets of predefined rules that establish when, how and what is the order in which certain actions take place .

Each device is assigned an IP protocol , an address. There are several types of internet addresses, but we will not go into details. Host is a domain name given to each network , and can be expressed either in the form of a string of numbers (192.168.0.1), or in letters to make it easier to remember ( www.institut-on.ro ).

There are a number of computers that connect networks and are called gateways . For each country there is an assigned domain (for Romania .ro) or there are also for: the commercial domain (.com), for education (.edu) etc.

Because data flows in packets, and must reach its destination as a whole, there are a number of devices that interconnect networks and redirect these packets, which are known as routers .

There are several types of routers, from those used at home (home router), to firewalls (used between LAN and WAN).
