What does packet mean?
A packet is a small bundle, package, or collection of related items. The everyday sense covers objects sold or carried in compact portions, such as a packet of crisps, biscuits, seeds, medicine, or cigarettes; it can also mean a group of documents or other items gathered together. In computing, a packet is a discrete unit of data transmitted across a network, containing information and usually a header that helps the data be routed and checked. In diplomacy and formal correspondence, the word can refer to an official written communication exchanged between governments or organizations. The word’s range—from a snack-sized bundle to a unit of digital information and a formal dispatch—makes it especially useful for describing something compact but complete in itself.

Etymology of packet
English borrowed the word from French, where it was a diminutive related to “pact” or “package,” meaning a bundle or package. The English word originally referred to a small bundle or parcel and later extended to groups of documents and other related objects. Its use in computing is a modern specialization based on the idea of a compact, self-contained unit being transmitted as part of a larger communication.
