Techopedia Explains Data Packet
A data packet has other parts besides the raw data it contains - often referred to as the payload. Data packets also have headers that carry certain types of metadata, along with routing information. For example, IP data packets have a header containing an IP address of origin and destination IP address. Data packets also may have trailers that help refine data transmission.
