what is an ISP Concept, ISP Technologies, Examples and How to know it

What is an ISP?

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

ISPs provide their customers with access to the Internet through a variety of technologies.What is an ISP

The Internet Service Provider (ISP), in computing, is the Internet Service Provider, that is, the company that sells the Internet connection to users.

Thus, the same ISP offers its set of clients 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 there can be several ISPs, which constitute a market among them all.

In its early days, the Internet was a technology limited to academia, government and science, so it needed specialized identification and access to use it.

But this limited their dimensions, and excluded the general public, increasingly interested in the infinite possibilities of the Web, so that in the early 90s a group of private companies decided to offer access points to the network, thus becoming the first commercial ISP.

Competition among ISPs eventually led to an ever-widening user market and new and faster connection technologies, which allowed the Internet to explode, taking it almost everywhere: cyber-cafés and locutorios initially, then to their users’ own homes and finally, as we can see today, to the cell phones they own.

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 telephony 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.

Examples of ISPs

Some examples of ISPs in different countries are:

  • Spain: Movistar, Vodafone, Orange, Yoigo, R (telecommunications), Euskaltel, Telecable, Adamo Telecom.
  • Argentina: Telecentro, Fibertel, Speedy, Gigared, Arnet, Cotelcam, Skymax, Sion.
  • United States: Comcast, Time Warner Cable, AT&T, Cox Communications, Google Fiber, Verizon.

How do I know my ISP?

In principle, in order to know our ISP it would suffice to check the name of the company to which you pay for Internet service, often the same company that provides telephony and/or cable television.

If we do not know it, it is possible to access this information through some free  that reveal information about the Internet protocols we use.

Some of them are Spyber.com or Ipcheck.org, and all you have to do is enter your URL in a browser window and wait for the complete information about your 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”.
