What exactly is the Internet Service Provider (ISP) ?

Internet Service Provider

Surfing the web, telephoning (IP voice), exchanging emails, watching videos via television or a streaming site: these are all things that require a good Internet connection to work perfectly. In USA, this connection is most often provided by ISPs. But what is an ISP? How do ISPs work and what are the various formulas offered by these entities ?

WHAT IS A Internet Service Provider (ISP)?

FAI is the abbreviation for “Internet Service Providers”, ISPs provide the Internet connection to their users using specific technologies. This internet connection can be limited and/or unlimited and calibrated according to the needs and economic capacities of the end user.

ISP in a practical way

The Internet Service Provider (ISP) is a service or organization (most of the time for a fee) that provides an Internet connection to third parties. In other words, the term FAI refers to all companies that offer consumers an Internet connection, allowing them to join the web.

Why did you use an ISP?

The Internet Service Provider (ISP) is an essential intermediary with large servers connected to dedicated lines. In doing so, it allows its subscribers to enjoy a network connection, most often unlimited with some bonus options.

However, unless you have a dedicated line, you are not able to connect to the Internet. It is therefore necessary to subscribe to one of the many American ISPs in order to access the Internet.

Thereafter, you will have to refer to your ISP for everything related to the management of your Internet connection and if you have subscribed to a mobile offer at the same time, you will address it for everything related to your mobile phone (SIM card, PUK code request etc…)

Differences between ISPs.

While the majority of ISPs offer similar basic services, they differ specifically in the number of services offered and the quality of service (QoS). Thus, it is all these criteria that will make it possible to differentiate ISPs. We therefore note mainly:

  • Coverage : some ISPs only offer local coverage of large cities while others offer coverage of the entire national territory;
  • Bandwidth : this corresponds to the total bandwidth offered by an ISP and is divided by the number of subscribers. The more subscribers there are, the more bandwidth allocated to each one decreases;
  • The price : it depends on the ISP and the type of subscription chosen. However, some ISPs offer free access;
  • Unlimited access : some ISPs offer a formula in which the connection time is counted for you. This means that you have a specific number of hours of connectivity available on a monthly basis;
  • The additional services : the number of email addresses (with their consultation by email software or via webmail), the space made available for the creation of personal web pages (HTML) or for file storage (cloud computing).

The various formulas offered by Internet Service Providers.

The subscription formulas and models offered by ISPs are vast and constantly diversifying.

  • Paid subscription with unlimited access : this is the formula traditionally offered. As you will have understood, it consists in paying a fixed fee each month, allowing you to connect as many times as you wish or need to during this period.
  • The paid subscription with limited access : this type of formula has the same characteristics as the previous one, with the difference that the subscription is less expensive and the number of connection hours is limited.
  • Internet access without subscription : far from being free, this offer occasionally allows you to connect by paying for access with a much higher per-minute communication cost. It is a formula adapted to those who only very rarely connect to the Internet.
  • Free access providers : through advertising, ISPs are able to offer you such a service. As soon as your connection is functional, you will see banners on your screens. This offer is rather advantageous, because the inconvenience caused by this type of advertising is relatively minimal.


To ensure a smooth Internet connection, which will allow you to quickly load web pages, download media at a glance and watch live online videos, ISPs use many technologies. The latter, which are equally effective, are mainly the ones presented below.

ADSL/VDSL internet offers

ADSL and VDSL connections are high-speed connections.

  • ADSL (Asymmetric Digital Subscriber Line) refers to high-speed Internet. It is a digital communication technique that allows digital data to pass through copper cables on telephone lines, independently of telephone service. It allows you to enjoy speeds of up to 30 Mega, giving you the ability to surf and download content very easily on the Net.
  • VDSL (Very-high-bit-rate Digital Subscriber Line) or VDSL 2 are technologies very similar to ADSL. Internet speeds are equivalent and/or better than those of ADSL. The VDSL allows a connection up to 55 MB/s. However, this flow can only be achieved if the dwelling is less than one kilometre from the Subscriber Connection Node.

USA internet

Fiber optics

Fiber optics, the emblematic technology of high-speed Internet, is made accessible to millions of households in the USA thanks to ISPs. Optical fibre refers to a new fixed network based on a very thin physical medium used for the transmission of very high-speed Internet Protocol (IP) data.

The optical fibre has a core within which light ricochets, thus remaining trapped in the cable. In doing so, the data, corresponding to very short light pulses, are conditioned to be transmitted at the speed of light. To date, optical fibre has been used to transmit data over the Internet up to 1 Giga, or 1000 Mega.

It thus multiplies by 100 the performance of a traditional ADSL network. In the future, even flows of up to several terawatts would be considered. With a speed of up to 1 Giga, the various uses of the Internet can be considerably improved.

3G or 4G mobile internet offers

Mobile phones are now real handheld computers. It is logical that they should be able to connect to the Internet via the mobile network. ISPs also offer mobile Internet services. There is also talk of broadband since we are talking about 3G (third generation) and 4G (fourth generation).

To enjoy a good Internet connection, you will therefore need to subscribe to a mobile Internet compatible package and have a smartphone capable of connecting to the Internet. ISPs now offer mixed mobile phone + Internet offers at home (quadruplay offer).

3G or 4G key offers

The 3G/4G key represents an interesting alternative to other technologies when no wifi connection is available nearby. The 3G/4G key is similar to a USB key that allows its users to benefit from an Internet connection wherever they are (outside the mobile white zone) and whenever they wish.

To operate, the 3G/4G key uses the networks of the various telephone operators (AT&T, Veryzon, AOL etc…). It is therefore equipped with a SIM card like mobile phones. Thus, it is necessary to subscribe to a subscription from an ISP to be able to benefit from Internet access.

You can therefore connect to the Internet wherever you are in the United States using 3G/4G keys by subscribing to one of the packages offered by the ISP of your choice. It is also about broadband as for mobile packages, allowing you an optimized experience on the web.

ISP final word.

In conclusion, an Internet Service Provider (ISP) is a company that provides Internet access using multiple technologies. To do this, it offers you many options, each one equally advantageous.

However, before choosing the appropriate ISP, it will be necessary to consider the advantages and disadvantages of such a subscription for your personal case, since the user experience varies from one user to another.
