- 1). Understand that when you send information (such as a file) over the Internet, the higher level, TCP, translates the information into small packets that can be sent easily from one computer to another. Each packet is labeled with its destination address, as well as the order it should go in when the packets are reassembled into one file.
- 2). Recognize that once the information has been properly bundled, the lower level, IP, locates the target IP address and sends the packets over the Internet to the target computer.
- 3). Realize that the IP layer of the target computer receives the packets and transfers them to the target computer's TCP layer, which assembles the packets back into information that the user can understand.
