We explain what the Internet is and what are the different types of Internet connection. Its history, its services and the different browsers.

Internet began as a military project of the United States.
  1. What is the Internet?

Internet is a network of computers that are interconnected worldwide to share information. It is a network of calculation equipment that relates to each other through the use of a universal language.

The Internet concept has its roots in the English language and is made up of the word inter (which means between ) and net (from a network that means electronic network ). It is a term that should always be written in uppercase as it refers to La Red (which connects computers worldwide via the TCP / IP protocol) and without an article ass accompanying him / her to refer you.

There are different types of internet connection, that is, different means by which one can get connected to the network of networks . The first of them was dial-up connection, that is, taking the connectivity of a telephone line through a cable. Then other more modern types emerged, such as ADSL, optical fiber, and 3G and 4G (LTE) connectivity for mobile devices.

To access the billions of websites available on the large network of networks, which we know as the Internet, we use web browsers (software), being some of the most used Google Chrome, Internet Explorer, Mozilla Firefox, and Safari, all developed by different technology companies.

  1. How did the Internet come about?

In 1989 the proposal was made to use computers and links to create a network.

It is said that the origin of the Internet is due to a military project developed by ARPANET (Advanced Research Projects Agency Networks), a computer network of the United States Department of Defense that sought to create a network of computers that linked the defense investigation centers in case of attacks to maintain contact remotely and its operation was not interrupted even though some of its nodes were destroyed. Anyway, its initial purpose was to find other uses for the computer besides the calculator.

In 1989, a first proposal was made to use computers and links to create a network, later known as WWW (World Wide Web) that refers to a set of rules that allows the consultation of hypertext files (http).

Sir Timothy Berners-Lee, a British engineer, made the initial proposal for WWW in that year and subsequently, through the implementation of http, achieved the first successful communication.

  1. Types of Internet connections

Since the Internet is a network, it can be accessed through several channels.

  • Telephone lines A telephone line can be used that is subdivided into conventional telephone lines (it transmits signals in analogue form but they were currently displaced by others that offer greater benefits) or digital (by using a network adapter, the resulting frames of the computer are translated into digital signals).
  • Fiber optic cable). It can also be a cable connection (which implements light signals instead of electrical signals that encode a greater amount of information and in turn, said cable is made of a material called optical fiber that allows it to transmit data between nodes).
  • Satellite Also, there is the satellite connection (normally we are talking about a hybrid satellite and telephone connection system to reduce the congestion present in terrestrial networks).
  • Wireless networks. In turn, we can implement wireless networks (which replace the cables with infrared light signals or radio waves to transmit information). In sum, within wireless networks, another method used is that of LMDS (which is an acronym that stands for Local Multipoint Distribution System and consists of using high frequency radio waves).
  • Electric lines. If we talk about electric lines, we use PLC (three-word conjunction: Power Line Communications ). Finally, we can use the mobile phone (which refers to mobile communications available to access the Internet).

  1. Internet services and uses

Internet allows us to communicate with family or friends over long distances.

The Internet opens the doors to thousands and thousands of different services, including:

  • Search for any type of information you need (for example on Google).
  • Buy products of various types (for example in Amazon or Mercado Libre).
  • Communicate with family or friends who are in other countries or cities through a video call (for example, Skype or WhatsApp).
  • Play online games (like the League of Legends) with people of different nationalities and ages, in real time.

Of course, a word that summarizes all these qualities that the Internet has can be connected or related. The Internet has the ability to connect people in different parts of the world and with different interests among themselves.

  1. Web browsers

Safari, created by Apple, is one of the fastest web browsers.
  • Chrome belonging to the giant Google and created in 2008; It is one of the fastest and safest offered on the market today. It is one of the best quality navigation programs today, which also offers its download for free.
  • Internet Explorer It is a service of greater antiquity, already discontinued, but which was once the market leader. Its creation dates approximately from the year 1995, and is launched on the market by the leading Microsoft company. During its first decade of existence it was the most used, presenting the greatest modernity, but today it has become one of the slowest despite its updates; which is why it has lost a lot of users.
  • Mozilla Firefox. It is presented as the alternative launched by the Mozilla company, which caused a furor in its inclusion in the market given the existing compatibility with both Apple and Microsoft operating systems. In addition, it is a fast service since it uses little memory (less hardware requirements) at the time of performing each search; but it presents the best security offered in the market so far.
  • Safari. created by Apple. Perhaps one of the fastest, absolutely compatible with the operating system of this brand, while the version compatible with Microsoft no longer receives updates; and therefore, the same performance is not obtained either.
