Let’s look at an example to help us understand –

Google’s server is thousands of kilometers distant from you in the United States. However, when you visit Google’s page, it loads in a matter of seconds on your device. All of this is possible because Google’s server and your device share a network.

As a result, it is the ISP’s responsibility to establish a connection between Google’s servers and your device. The ISP uses fiber optic cables, telephone towers, and satellites to do this. ISPs are, in a sense, the Internet.

Many specialized telecommunications, networking, and routing devices are necessary to connect any device to the Internet, such as a mobile phone or a laptop. Because the average person cannot afford such equipment, ISPs rent their networks to enable internet access.

Types of ISP

Internet Service Providers are classified into three categories.

  1. Tier-1
  2. Tier-2
  3. Tier-3


This type of ISP remains at the top of the list and has a global reach, meaning that Internet service may be accessed from one country to another through them; it is known as the Internet’s backbone.

ISPs at this level establish peering arrangements with one another to provide infrastructure for moving traffic from one geographic area to another.

Peers are ISPs that interconnect and collaborate to pass free traffic to one another at the same level. Without a Tier-1 ISP, internet traffic cannot be transmitted from one country to another.

Example:- Tata Communication, AT&T, Verizon, Sprint, etc.


Those businesses that use fiber technology to connect the internet from the sea to their residences fall into this category.

The tier-2 organization leases internet authority from Tier 1 organization. Every time we pay our phone’s internet recharge cost, the money travels directly to Tier 2 corporations.

Examples:- Airtel, Idea, Vodafone, BSNL, JIO, etc.


ISPs at this level purchase internet from Tier-2 ISPs based on traffic, and their job is to give internet access to end-users, such as households and businesses, in exchange for a fee.

Examples:- Den Broadband,Excitel,Tikona etc.

Types of ISP Connection

1) Dial-up Connection 

All of the connections that allow us to connect more than one computer to the Internet are classified as dial-up connections and include telephone lines, fiber optics, microwave transmission, and communication satellites, through which the entire world is connected.

The telephone also makes use of it. Whose internet connection is substantially slower than it is now. In many regions, for example, where broadband cables are not available, the Internet is accessed using dial-up connections.

2) DSL Connection 

DSL stands for Digital Subscriber Connection, and it uses a telephone line to link any internet user to the internet. This connection is a little slow, with speeds ranging from 5 to 35 Mbps.

3) Fiber internet

Fiber Internet is becoming more widely used these days. Fiber Internet uses fiber optic cable to transport all of its Internet services, resulting in extremely fast speeds.

4) Cable

This service makes use of coaxial cable, which is the same cable that is used for television. Cable-delivered internet services provide a faster speed than other options.

It provides a speed of 10 to 500 Mbps, which is fairly fast when compared to other services.

5) Wi-fi

WIFI connections are now deployed in every house, college, and company, allowing everyone to work without interruption. The majority of fiber lines are also used in WIFI.

6) Satellite internet access

It uses communication satellites to provide internet services. It offers internet speeds ranging from 12 to 100 Mbps.

Can ISP Check Our Internet Activity?

All requests to the Internet are managed by the Internet Service Provider. Whatever we search on the internet or in a search engine in such a situation. The Internet Service Provider receives the request first (ISP). The ISP then forwards it.

How does the ISP connect the user to the Internet?

The ISP connects you to your network when you take a SIM card and reload it.

The ISP allocates an IP address to your device after connecting you to the network so that it may be uniquely identified.

Now, when you make a search on the Internet, your ISP knows you by your IP address and presents the results of your search on your device.

How does an ISP work?

An ISP has its own data centers with several servers and is connected to one or more Internet lines. These data centers handle a significant amount of traffic and requests.

Advantage of ISP

An ISP (internet service provider) is a corporation that provides internet access and other associated services to consumers and enterprises. An ISP has the necessary equipment and telecommunications line access to establish a point of presence on the internet for the service region.

Disadvantage of ISP

The main disadvantages of larger ISPs are that they rarely provide the same degree of personalized service as smaller providers, and they may have so many clients that employees of a small business may have difficulty acquiring access during peak business hours.
