CPU Cycles is the process the processor takes to complete a command.
Multiple cores came about due to the current CPU overheating above 4GHZ .
So they started adding more cores to the existing processors to give you
more cpu threads to process commands. So in theory you can have a 3GHZ CPU
with dual cores (2 central processing units) to get the result of a 6ghz
processor.

You are correct, the 4GB limit was imposed by the operating system . 64bit
has been around for years, I believe someone else mention this on the
thread, its not new and unix/linux has been using it.


"If you imagine wires or cables as lanes on a motorway then double the
number of lanes can carry double the number of cars.  It's just that you
don't always need to have that many cars on a section of motorway.  "

I like that ,
