It is "wired down" in that the system can't reallocate that memory for another purpose. The term does seem a little odd, because "wired memory" was a term used to describe read-only memory back in the early days where it really was made up of wires. Mac OS X's "wired memory" is certainly not read-only. I haven't found anything which clearly explains where the Mac OS X usage of the term originates. The best analogy I can think of is a garden where part has been covered in mesh wire to protect it. You can't uproot the plants in the wired section without first removing the wire netting, but the rest of the garden can be uprooted and replanted at will. -- David Empson dempson(a)actrix.gen.nz |
