What is the ISP?
The ISP ( Internet Service Provider ), in computer science, is the Internet Service Provider , that is, the company that sells the Internet connection to users.
Thus, the same ISP provides its clients with access to the Web through different means or technologies (DSL or “broadband”, Dial-up, cable modem, GSM, etc.), and in the same country or region they can There are different ISPs, which together constitute a market.
In the beginning, the Internet was a technology limited to the university, government and scientific fields, which required a specialized identification and access to use it. But this limited its dimensions, and excluded the large public, increasingly interested in the infinite possibilities of the Web, so in the early 90s a group of private companies decided to offer access points to the network , thus becoming the first commercial ISPs
Competition between ISPs eventually led to an increasingly broad market of users and new and faster connection technologies , which allowed the great information explosion of the Internet, taking it to almost everywhere: cyber-cafes and booths initially, then to own homes of their users and finally, as we can see today, the cell phones they own.

The main technologies used by ISPs to provide their users with an Internet connection are:
- Dial-up ( dial-up connection) . Connection through the telephone network.
- ADSL (broadband). Connection through an asymmetric digital subscriber line (hence the acronym).
- CATV . Connection via television by subscription (cable).
- Mobile phone network . For “smart” cell phones, either UMTS (Universal Mobile Telecommunications System) or HSDPA (3G technology).
- Wireless network ( WiFi ) . Connection via radio waves for computers and cell phones.

How to know my ISP?
In principle, to know our ISP it would be enough to review the name of the company to which you pay Internet service , often the same one that gives us telephony and / or cable television. In case we do not know, it is possible to access this information through some free web pages that reveal information about the internet protocols we use.
Some of them are Spyber.com or Ipcheck.org, and just enter your URL in a browser window and wait for the full information of our connection and computer, such as IP address, server, remote port, and ISP. The latter can be called through those acronyms or simply as “Internet Service Provider”.
