What is internet.?
A network is a set of devices (often referred to as nodes) connected by communication links. A node can be a computer, printer, or any other device capable of sending and/or receiving data generated by other nodes on the network. A link can be a cable, air, optical fiber, or any medium which can transport a signal carrying information.
How it works?
The Internet is not like a telephone network. The global Internet consists of tens of thousands of interconnected networks run by service providers, individual companies, universities and governments. In most countries, a telephone network is run by a single company for several years at a time. Open standards are what enable this network of Internet networks to communicate. And they’re what make it possible for anyone to create content, offer services, and sell products without requiring permission from a central authority.

What is the cost of internet?
In the case of internet, there is no such cost. Suppose I have a cable from my home to the office under the ground. Then a communication was made from home to my office. The cost of this communication is the cost of maintenance and upkeep. Damage to cables due to marine life and adverse weather costs for maintenance and therefore internet costs.
