Handle

Tags:

As your screen name, the name you utilize is usually referred to in online chat, or handle. If you decide to brand yourself MooCow123 that might be your handle. Any name can be used as a handle name.

In traditional implementations, file descriptors are indices into a (per-process) file descriptor table, thence a (system-wide) file table.
