How E-mail Works
TCP/IP
Each computer connected to the Internet has software installed called TCP/IP.
TCP/IP is a common language on the Internet so that all computers can communicate
with each other even though they are using different operating system.
Take, English Language, as an example. There are ten peoples from different countries, say,
China, Amercian, Africa, Japan, Korea, Thailand, India, etc. Since both of them can speed
English, they can communicate with each other. We can say in this case, English Language
is their "TCP/IP" ! We will send a email to show how data transfer over the Internet.
