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.
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.
