“packet”的概念、定义、翻译、参考文献-科学参考

packet

Computer

A group of bits of fixed maximum size and well-defined format that is switched and transmitted as a composite whole through a packet switching network. Any message that exceeds the maximum size is partitioned and carried as several packets.
Typically each packet contains addressing information defining the source and the destination of the packet, control information defining the type of data carried in the packet, and some form of checksum to verify that the packet has been correctly received. In many systems the packet may hold several hundred bytes and the internal structure can vary from one packet to the next. See also cell, frame.

Internet

A collection of data which is sent through a network to a destination computer. As well as data the packet contains subsidiary information such as the address of the computer which sent the packet and the address of the destination computer. A transfer of information normally involves the splitting of the information to be sent into packets.

Electronics and Electrical Engineering

A segment of a digital signal – i.e. a group of bits – that travels through a communications network as an information unit. Each packet has a fixed maximum size, and includes information about its source and destination. See also packet switching; digital communications.
