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

The Internet began as a military project of the United States.

What is the Internet?

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

The conceptInternet has its roots in the English language and is made up of the word inter (What does it mean Come in) Y net (from network What does it mean electronic network). It is a term that must always be capitalized since it refers to "The Network" (which connects computers worldwide through the TCP / IP protocol) and without a Article to accompany him / her for reference.

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

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

How did the Internet come about?

In 1989 a 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 Ministry of Defense that sought to create a network of computers that it would unite the defense research centers in case of attacks to maintain contact remotely and not interrupt its operation despite the fact that some of its nodes were destroyed. In any case, his initial purpose was to find other uses for the computer in addition to being a 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 files of hypertext (http).

Sir Timothy Berners-Lee, a British engineer, made the initial proposal for WWW in that year and later, by implementing http got the first successful communication.

Types of Internet connections

As the Internet is a network, it can be accessed through various channels.

• Telephone lines. You can use a telephone line that is subdivided into conventional telephone lines (transmitting signals in an analog way but currently they were displaced by others that offer greater benefits) or digital (through the use of a network adapter, the resulting frames are translated from the computer to digital signals).
• Cable (optical fiber). Likewise, it can be a wired connection (which implements light signals instead of electric 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. There is also a satellite connection (normally we are talking about a hybrid satellite and telephone connection system to reduce congestion on terrestrial networks).
• Wireless networks. In turn, we can implement wireless networks (which replace cables with infrared light signals or waves radio to transmit information). In short, within wireless networks, another method used is LMDS (which is an acronym that stands for Local Multipoint Distribution System and consists of using high frequency radio waves).
• Power lines If we talk about power lines we use PLC (conjunction of three words: Power Line Communications). Finally, we can use mobile telephony (which refers to communications available for cell phones to access the Internet).

Internet services and uses

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

Internet opens the doors to thousands and thousands of different services, among them it will allow us to:

• Search for any type of information you need (for example in Google).
• Buy products of various kinds (for example on Amazon or Mercado Libre).
• Communicate with relatives or friends who are in other countries or cities through a video call (for example Skype or WhatsApp).
• Play games online (like 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 possesses can be connect or relate. The Internet has the ability to connect people in different parts of the world and with different interests with each other.

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 programs browser of the best quality today, which also offers its download absolutely free.
• Internet Explorer. It is an older service, already discontinued, but which was the market leader at the time. Its creation dates from approximately 1995, and is the one launched on the market by the leading company Microsoft. 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, he has lost a large amount of users.
• Mozilla Firefox. It is presented as the alternative launched by the Mozilla company, which caused a sensation in its inclusion in the market given the existing compatibility with operating systems both Apple and Microsoft. In addition, it is a fast service since it uses little memory (less hardware) at the time of each search; but it presents the best security offered on 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.
