Internet
The global network that carries e-commerce.
How an online purchase uses the Internet
When a customer orders a product online, the request is broken into packets (packet switching), addressed and routed using TCP/IP, and exchanged between the customer's client device and the merchant's web server using client/server computing.
Internet hosts grew from 70 million in 2000 to over 1 billion in 2016 across 245+ countries.
