Instructions & Programs: Crash Course Computer Science #8
Take the 2017 PBS Digital Studios Survey: http://surveymonkey.com/r/pbsds2017. Today we're going to take our first baby steps from hardware into software! Using that CPU we built last episode...

Hi, I’m Carrie Anne and this is Crash Course Computer Science! Last episode, we combined an ALU, control unit, some memory, and a clock together to make a basic, but functional Central Processing Unit – or CPU – the beating, ticking heart of a computer. We’ve done all the hard work of building many of these components from the electronic circuits up, and now it’s time to give our CPU some actual instructions to process! The thing that makes a CPU powerful is the fact that it is programmable – if you write a different sequence of instructions, then the CPU will perform a different task. So the CPU is a piece of hardware which is controlled by easy-to-modify software! INTRO Let’s quickly revisit the simple program that we stepped through last ...
