1. A portion of data that is passed from computer to computer in token-ring networks. When a computer has a token, it is capable of communicating to other computers and devices on the network.
2. When referring to programming or batch files a token often refers to a segment or portion of a much larger piece of data. For example the date: 09/02/2007 could be broken into tokens: 09, 02, and 2007. Once these tokens have been gathered the programmer can use only portions of the data they want, for example, in the case of the date only the day and not the month or year.
