Windows Embedded

The world is filled with PCs in the most unlikely places. Everything from cash registers to the F-22 Raptor fighter plane contains some number of tiny PCs. These aren’t the PCs you’re used to seeing, though. They almost never have mice, monitors, keyboards, and the usual I/O you’d expect to see, but they are truly PCs, with a CPU, RAM, BIOS, and storage.

These tiny PCs need operating systems just like any other PC, and a number of companies make specialized OSs for embedded PCs. Microsoft makes Windows Embedded just for these specialized embedded PCs.

For all practical purposes, the terms microprocessor and central processing unit (CPU) mean the same thing: it’s that big chip inside your computer that many people often describe as the brain of the system. From earlier in the book, you know that CPU makers name their microprocessors in a fashion similar to the automobile industry: CPU names get a make and a model, such as Intel Core i7 or AMD Phenom II X4. But what’s happening inside the CPU to make it able to do the amazing things asked of it every time you step up to the keyboard?

Historical/Conceptual

CPU Core Components

Although the computer might seem to act quite intelligently, comparing the CPU to a human brain hugely overstates its capabilities. A CPU functions more like a very powerful calculator than like a brain
