ISP Explained

ISP stands for Internet Service Provider, the company that charges you a monthly fee in order to access the Internet via wireless, satellite, DSL, cable or dialup connection. Throughout North America, there are ISPs of all sizes ranging from major telecommunications conglomerates to locally owned and operated companies like Pure High-Speed, with each providing a different yet similar set of services at competing prices. When selecting an ISP, it is important to do your research and learn what each company offers to determine the best value for your hard-earned money.

What Does an ISP Do?

PlanningOnce you have entered into an agreement with the ISP of your choice, you are able to connect to the World Wide Web using all of your Internet enabled devices, such as laptop and desktop computers, smartphones, tablets and even video game consoles if someone in your family enjoys online gaming. In addition to providing access to the Internet , many ISPs also allow website building and virtual hosting.

With the proper equipment and telecommunication lines, your ISP has a point of presence on the Internet for your particular geographical location. By leasing their own high speed lines, larger ISPs are less reliant on telecommunications providers and deliver superior service to their customers.

Whenever you download anything from the Internet – including web pages, images, videos, documents and any other files – it is transferred through your ISP by running requests from your network to access the data held on servers hosted by websites’ own ISPs. This connection is possible only if both ends of the communication have valid public IP addresses assigned by your respective ISPs. Most individual customers are given dynamic IP addresses that always change, while websites possess static IP addresses that remain the same.

How Does It Work?

Blockchain technologyNow that the Internet is part of daily life for most people, it can be easy to take for granted the amazing process that occurs within seconds every time you open a web page or download a file. Using the DNS servers set up on your device, your request is sent through your home router to your ISP, which attempts to access the desired information via the public IP address set up for the website by its own ISP. If the connection is successful, the web page or file you want is sent from servers hosted by the site’s ISP back to your own ISP before the data is forwarded through your home router directly to your wired or Wi-Fi Internet enabled device. Whether it’s an important business document, a Google search or a video on YouTube, the requested data is delivered almost instantaneously, an incredible feat that would have been considered miraculous only a few years ago.
