What is the ISP?

We explain what an ISP is and what connection technologies it can use. Some examples and how to detect what your ISP is.

  1. What is the ISP?

The ISP (acronym for Internet Service Provider ), in computer science, is the Internet Service Provider , that is, to 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 several ISPs, which constitute a market among all.

In the beginning, the Internet was a technology limited to the university, government and scientific fields, so it was necessary to have a specialized identification and access to use it. But this limited its dimensions, and excluded the general public, increasingly interested in the endless possibilities of the Web, so in the early 1990s a group of private companies decided to offer access points to the network , thus becoming the first commercial ISPs.

The competition between ISPs eventually led to an increasingly wider user market and new and faster connection technologies , which allowed the great information explosion of the Internet, taking it almost everywhere: cyber-cafés and call centers initially, then to their users’ own homes and finally, as we can see today, the cell phones they own.

  1. ISP technologies

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 via an asymmetric digital subscriber line (hence the acronym).
  • CATV Connection via subscription television (cable).
  • Mobile telephone network . For “smart” cell phones, either UMTS (Universal Mobile Telecommunications System) or HSDPA (3G technology).
  • Wireless network ( WiFi ) . Connection by radio waves for computers and cell phones.

  1. 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 for the Internet service , often the same that provides us with telephone and / or cable television. In case we do not know it, 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 window of our browser and wait for the complete information of our connection and computer, such as IP address, server, remote port, to be displayed, and ISP. The latter can be called through these acronyms or simply as “Internet Service Provider”.
