[Vocabulary] cached

" In UNIX, disk inodes are cached in memory. "
(from Expert C programming p.1555)

Does it means that inodes are first written somewhere and then move to the disk?If so, What is that somewhere?

Or, does it mean inodes are acting as the caches for the physical memory?

Does it means that inodes are first written somewhere and then moved to the disk? If so, [STRIKE]W[/STRIKE] what is that somewhere? Yes, they are cached (v.) in a cache (n.).

Or, does it mean inodes are acting as the caches for the physical memory? No, an inode is just data, just information, to be stored.

That's a question about UNIX internals.
Or, does it mean inodes are acting as the caches for the physical memory?

You seem to have got your answer - by happy accident. This forum deals with language.

Most contributors to this forum have as little idea about what an 'inode' is as most C programmers have about how to pronounce 'cache'.

Cache is used to store information that is most probably going to be used again. And that information can be easier (and faster) retrieved from the cache memory than creating it one more time or retrieving it from another place. I am not very knowledgeable in UNIX file-system, but I can give you another example: when you visit a website for the first time, the images are downloaded in a cache memory (in your computer) so next time you visit the website you will not have to download the images again (avoid bandwidth waste, for both you and the server which hosts the website).

Is it supposed to sound like "cash"?

Opinions differ, and I imagine dictonaries exist that allow either, but making the a sound /eɪ/ on the strength of the final e seems to me inappropriate; and it flies in the face of the word's derivation (not crucially or unarguably important in itself, but it strikes me as having some weight).

[not a teacher]

For me, yes, which distinguishes it from cachet.

How would you say it?

Cache | Define Cache at Dictionary.com

This only gives the "cash" pronunciation. I would think the French word "cacher" would sound like "cash-eh." (Like a Canadian asking for money.)

Yes, the infinitive does. That doesn't mean that all French-derived words ending e have to be pronounced as if it were é.

True. I've never heard anyone pronounce "cache" like "cash-eh." That would grate.

Thank you all
