  • Sound is air vibration

    Sound is not exclusive to air, it can be generalized to vibrations in any media. Whale song and dolphin echolocation are certainly sounds, and we’re almost always talking about them propagating in water rather than air.

    which has to travel from one place to the next

    No, that isn’t how sound works. In air this would be a description of wind, not sound.

    just transfer kinetic energy to the adjacenct atom

    This is actually a good description of how sound waves propagate.



  • I’m not sure who told you that an installation on a USB thumb drive should boot “almost instantly” - that’s a much slower device than a proper HDD or SSD, and it’s normal for booting off of those to at least take a bit of time. The slow boot and the slow performance when running are probably both the same thing - slow disk I/O. A fast CPU helps run computations quickly, but installing and launching programs involves a lot of writing and reading files, which doesn’t have much to do with CPU speed.
