[From the last episode: We looked at different categories of processor] We’re going to look at big and little microprocessors, but before we do that, it’s helpful to understand how engineers count so that we can discuss memory addresses more easily. It’s hard for me to know how obvious this […]

[From the last episode: We looked at the role of the operating system in computers.] We often toss around the words “microprocessor” and “CPU” as if they were self-defining. But, in fact, there are lots of different types of processor. Let’s review a few of them here, since different types […]

[From the last episode: We took a quick look at software and how compilers create machine code.] We’ve seen the big-picture version of what a processor does. And we’ve seen software that runs on it. But, depending on the kind of system we’re looking at, it may not be that […]

[From the last episode: We looked at the role of a processor in a typical system.] We’ve taken a very brief, high-level look at a processor – and we’ll have lots more to say about them. But before we do that, let’s keep going with some of this big-picture stuff. […]

[From the last episode: We reviewed the wide range of topics we’ve covered in the area of IoT security.] We now change directions away from security (for the moment, anyway). We’re going to pursue notions of computing, the fourth aspect of the IoT. We’ve already covered the other three – […]
