Internet Definition
The Internet is a network of computers that are globally interconnected to share information. It is a network of computing equipment that relate to each other through the use of a universal language.
The concept Internet has its roots in the English language and is made up of the word inter (between) and net (electronic network). It is a term that must always be written in capital letters. Since it refers to “The Network” (which connects computers worldwide through the TCP / IP protocol.) And without an article to accompany it (the / the) to refer to it.
There are different types of internet connection, that is, various means by which one can obtain a link to the network of networks. The first of these 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 billions of websites available on the large network of networks, which uses the Internet, web browsers (software). And, the use of it is mostly in Google Chrome, Internet Explorer, Mozilla Firefox, and Safari, The development of all by different technology companies.
How Did the Internet Come About?
The development of a military project by ARPANET (Advanced Research Projects Agency Networks) has a saying as an origin of the internet, a computer network of the United States Department of Defense that sought to create a computer network that would unite the defense research centers in the event of attacks to maintain remote contact and do not interrupt their operation even though some of their nodes were destroyed. Anyway, its initial purpose was to seek out other uses for the pc 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), which refers to a set of standards that allow the consultation of hypertext files (HTTP).
Sir Timothy Berners-Lee, a British engineer, made the initial proposal for WWW in that year. And later, by implementing HTTP, I 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 subdivides into conventional telephone lines. It transmits signals in an analogical way. But currently, there is a displacement by others that offer greater benefits. Or digital through the use of a network adapter
Fiber Optic Cable
Also, it can be a cable connection which implements light instead of electrical signals that encode a greater amount of information.
Satellite
Also, there is the satellite connection (we are usually 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 cables with infrared light signals or radio waves to transmit information). In short, within wireless networks, the use of it is in another method that is LMDS (Local Multipoint Distribution System)
Power Line
If we mention power lines, we use PLC (conjunction of three words: power cable Communications). Finally, we can use mobile telephony (which refers to communications available for cell phones to access the Internet).
