Perl - A "namespace" for global variables, subroutines, and the like, such that they can be kept separate from like-named symbols in other namespaces. In a sense, only the package is global, since the symbols in the package's symbol table are only accessible from code compiled outside the package by naming the package. But in another sense, all package symbols are also globals--they're just well-organized globals.

Perl - The entire hardware and software context in which a program runs. A program written in a platform-dependent language might break if you change any of: machine, operating system, libraries, compiler, or system configuration. The perl interpreter has to be compiled differently for each platform because it is implemented in C, but programs written in the Perl language are largely platform-independent.

Perl - A "variable" in a language like C that contains the exact memory location of some other item. Perl handles pointers internally so you don't have to worry about them. Instead, you just use symbolic pointers in the form of keys and "variable" names, or hard references, which aren't pointers (but act like pointers and do in fact contain pointers).

Perl - The part of the address of a TCP or UDP socket that directs packets to the correct process after finding the right machine, something like the phone extension you give when you reach the company operator. Also, the result of converting code to run on a different platform than originally intended, or the verb denoting this conversion.
