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.
