What is internet.

The Internet is the global system of interconnected computer networks that uses internet protocol(TCP/IP) to communicate between networks and devices.

internet is just connection of devices through wires, cables. whole world is connected. connection is done by different companies let's have a brief idea.

Tier 3 company works on local wise.

How does Internet work.

when two people chat from INDIA to SINGAPORE internet is made used ,packet (data) which we want to send from one machine to another machine will travel the routing path with data protection in such a way that in middle one can decode that data. 

up-to one point data will travel through Wi Fi but whole world is connected through cables, like optical fiber which carry the data(packets).

The ISP which we make use (to which we are paying money) they will carry our data and send upto India border once its touches the Singapore there ISP will carry the packets and they will make sure data will reach the end user.

both the countries are paying for optical fiber laying through sea, so both countries are making use of it.

IP address is given to all devices which helps identify the device.
