Computer memory

    I am trying to get my head around computer memory, and more in a practical sense than theoretical.

    I study physics so I understand how it works and all the different values but I was wondering whether anyone knew any sites that gave practical examples of memory so that if I heard a memory value I could better relate to it instead of it just been a number with no physical meaning to me?

    Thanks

    Sorry if this comes across rude, but I've no idea what you're asking. Could you maybe try that again?

    Sorry, it probably is a bit vague.

    All I am asking is some way to easily relate to memory. E.g. from what I have seen an average song takes up 3-4Mb of memory. I want a way to differentiate between the different scales instead of just knowing that one is some factor of 10 larger than the other.

    Right, well first things first, computer memory usually refers to RAM. I know hard drive space is a type of memory, but it's confusing. I'm not really sure what you're after, but...

    A typical song takes up about 5MB. A good rule of thumb is that it's about 1-1.5MB for one minute of music (dependant on quality)
    A word document is usually less than 100KB (0.1MB)
    A TV episode is about 350MB
    A standard movie is about 700MB
    A high quality movie is about 1-2GB
    A Full 1080p movie is anywhere from 5-15GB.
    A modern game is anywhere from 3-20GB.

    Don't know if that's at all what you were looking for, but hey.

    Yes that is exactly what I was looking for. Just wanted something to give a rough idea. Thanks
