An ISP (internet Service Provider) Is a company that purchases transport lines at wholesale and resells access to these facilities to consumer and business clients.
For example a local ISP will purchase or lease equipment that will facilitate connectivity to an UPSTREAM provider (a ISP that is larger than themselves that they connect with for the purpose of becoming a node on the internet) and then resell off of this FARM of equipment connections to end users or other wholesale source.
The internet is not owned by any particular source and as such they do not purchase connectivity to the 'INTERNET' as such rather than lease connectivity to another carrier that itself has one or more connections to other carriers, which have one or more connections to other carriers; and so on. this endless 'WEB' of connections and interconnections is what forms the 'WORLD WIDE WEB'
So if company A is connected to company B and Company B is connected to company C.... AND a customer of Company A sends an email to a customer of Company C then the ROUTING tables (Sets of rules in routers) knows that it is not connected to company C... SO.... It simply sends its message to company B which it is connected to.... Company B's equipment says... HEY... I am connected to Company C so passes it on..... Company C then looks at the header and says.... HEY..... This message (Email for example) belongs to one of my customers by the name of XXXX... I will place it in his mailbox; and deliver when customer XXXX is connected next.
In short this is how the internet works.
