Internet Protocol (IP)
IP is the address—where to connect based on hosts and networks.
IP forwards packets based on 4 byte addresses, each unique.
Here is the structure of an IP address (8 bits = 1 byte).
The host name is a translation of an IP address, for example: 152.2.81 = ils.unc.edu.
TCP verifies the correct IP address—how to connect. It is the protocol for disassembling and reassembling packets. TCP verifies the correct delivery of packets by automatically triggering retransmission if there is a problem.
TCP groups data as a packet of bytes and assigns each packet a header and a trailer.
Packets are files translated into binary code. Each packet is 1,000 to 1,500 bytes.
UDP is used to send very large packets, such as those used for sound or video. While TCP packets are 1,000-1,5000 bytes, UDP packets can be up to 64 kilobytes in size. Unlike TCP, delivery of UDP packets is not ensured.
