1. A simple item of data that identifies a resource. For example, a Unix file handle identifies an open file and associated data such as whether it was opened for read or write and the current read/write position. On the Macintosh, a handle is a pointer to a pointer to some dynamically-allocated memory. The extra level of indirection allows on-the-fly memory compaction or garbage collection without invalidating application program references to the allocated memory. 2. An alias used intended to conceal a user' s true identity in an electronic message. The term is common on Citizen' s Band and other amateur radio but, in that context usually means the user' s real name as FCC rules forbid concealing one' s identity. Use of grandiose handles is characteristic of crackers, weenies, spods, and other lower forms of network life true hackers travel on their own reputations. Compare nick. [Jargon File] (2004-07-20)
