The demands for PCs to run larger programs, as well as more programs, grows daily. The move from 32-bit to 64-bit processing continues to create challenges for technicians, and it’s critical that we understand the differences and effects of choosing one of the other.
- You know, it's always fun to look at the bottom of a CPU.…It's got so many little wires or little pad contacts.…On modern CPUs can be over 2000 of these little connectors.…And you always wonder, why does it need so many connectors?…Based on other episodes, we've learned stuff like the…external data bus, which is going to be in our examples,…we only used eight wires.…And I'm sure set one of these is probably a clock wire,…and a few of these are probably voltage…and a few of these are ground.…
But why so many wires?…Well, I'm going to add to the list here a little bit…and talk about something very important.…We know that the CPU has to grab lines of code from RAM.…The question is, how does it do it?…It's actually really fascinating.…Let me show you.…So here's my CPU.…Now the CPU has an external data bus, in this case,…I'm just going to say it's an eight bit external data bus.…There are a lot bigger today, but this will get us started.…Now that external data bus doesn't just…come out of the CPU and end,…it extends throughout our computer.…
