Internet and Its Different types

What is the Internet?

The Internet is a network of computers that are interconnected worldwide to share information. It is a network of computing equipment that is interrelated 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 which means electronic network ). It is a term that should always be capitalized since it refers to "The Network" (which connects computers worldwide through the TCP / IP protocol) and without an accompanying article (the / her) to refer to it. There are different types of Internet connection, that is, different means by which one can obtain the connection to the network of networks

. The first one 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 ADSL, fiber optics, and 3G and 4G (LTE) connectivity for mobile devices.

To access the trillions of websites available on the vast network of networks, we know as the Internet,  the used web browsers ( software ), 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?

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 computer network that would unite the defense research centers in case of attacks to maintain contact remotely and not interrupt their operation even though some of their 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), which 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 later, through the implementation of HTTP, he achieved 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 (it transmits 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 ( fiber optic ).  Likewise, it can 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.  There is also the connection via satellite (normally we are talking about a hybrid connection system for satellite and telephone to reduce the congestion present in terrestrial networks).
  • Wireless networks. In turn, we can implement wireless networks (which replace cables with infrared light signals or radio waves 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 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 on Google ).
  • Buy products of various kinds (for example on 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 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 to connect or to relate. The Internet can connect people in different parts of the world and with different interests to each other.

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 available today, which also offers its download 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 it has lost a large number 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 operating systems from both Apple and Microsoft. Besides, it is a fast service since it uses little memory (fewer hardware requirements ) when performing 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.
