2.3.2 How TCP/IP works?

Messages sent over TCP/IP  are called packets.  Each packet of information sent over the Internet can be thought of  as a letter.  TCP/IP puts each letter in an envelope, addresses the envelope  with “To” and “From” information , and sends the letter on its way.  These packets are designed to be small, usually 1500 bytes
