Choosing an Internet Solution Provider (ISP)

What is an ISP?

 Can you think of a world without internet? Can you spend a week without access to the internet? The obvious answer would be a big ‘NO’. Internet has become the backbone of all our communications. How do we get access to the internet? This article will teach you the way you can get internet access. 

As the name suggests, Internet Service Provider is a company that provides internet access to individuals and companies for a specific fee. ISPs can take you to the world of internet by way of using the latest data transmission methods. These are mainly categorized into four. These methods by which ISPs connect their subscribers to the internet are dial-up, Cable Modem, DSL, wireless or by using high-speed interconnects. An ISP can offer you other related services too. They include website hosting and other virtual hosting such as server hosting. Now let’s look into each of the data transmission technologies in detail.

1)      Dial-up: As the name suggests, Internet Service Providers gives you internet access by using your telephone lines. A subscriber gets a dialed connection over the phone line to the particular ISP by making use of a PSTN (remember the old days of AOL?). PSTN stands for Public Switched Telephone Network. The information coming in and out of a system is controlled by a router of the subscriber which has a modem attached to it. This is made possible when the internet protocol packets are encoded and decoded by the attached router. One drawback with the dial-up connection is that a subscriber won’t be able use the phone line for voice calls while being connected to the internet and the connection is very slow. I don’t know anyone that uses dial-up connection anymore. If you are reading this blog from a remote part of the world with no other connection options available, you may be using dial-up.

2)      Digital Subscriber Line (DSL): DSL is another high-speed connection method being used by ISPs. Here also, the regular telephone lines are in use. However, one good thing about the DSL connection is that the phone line can be used for voice calls while at the same time connecting to the internet. DSL connections are faster than dial-up connections in 99% of the time.

3)      Cable Modem: An ISP sometimes gives access to internet by using the coaxial cable that gives us access to cable television at our home. Like in the case of a television channel, the cable modem system puts downstream data into a 6 MHz channel. (Downstream data is the data transferred from the internet to any individual computer on a network). The mechanism used here is the same as that of a television channel. What is more interesting is that it requires only a lesser bandwidth for the computer to send some information back to the internet (upstream data). However, the ISP will need to have the Cable Modem Termination System at its end to provide internet access in this manner. Cable modem connections are so fast compare to the other connections we are discussing in this blog.

 4)     Wireless: As you have guessed, ISPs use this technology for transferring information without any wires at all. The theory is just the same as in any remote control that we use nowadays. The difference is in the case of distances though.

So how do you decide on the selection of ISP? My recommendation is cable modem but it may not be available in all the areas. If it’s not available, ask your telephone carrier for fiber internet connection such as FIOS. If both options are not available, DSL should be considered. Do your research and find out who is offering the best service and price in this regard. Please let me know if I can guide you in anyway by emailing me at info@protechitsolutions.com.
