- One area that gets a lot of confusion…is the concept of chipsets,…so let me clear that up for you right now.…In order to appreciate chipsets,…you have to appreciate what was happening…before chipsets took place.…I've got a perfect example of this…right here in front of me.…This is a very, very old motherboard…and if you take a look at this motherboard,…you'll see that it's got all kinds of chips…just covering it.…These chips have all kinds of functions.…This chip right here does nothing but talk to the keyboard.…This chip right here does nothing…but talk to the hard drive.…
This chip right here does nothing…but talk to the serial port and parallel port.…There's another chip in here that doesn't do anything…but talk to the floppy drive.…The problem is that having individual discrete components…that had single function,…well, it made motherboards expensive.…So, what happened over time is that we began to get VLSA,…very-large-scale integration technologies…that started to take all these different functions…and consolidate them.…
