Summary
In this chapter, we went through different functional blocks in an embedded system. Not all of them are always present in a system, but having this basic understanding will allow you to classify the different components in a system. You really need to concentrate on the Safety section in the previous chapter, which is the most important section of the whole chapter. Don't be overconfident; be wary of electricity – nobody wins against physics.
With the knowledge of these different blocks, you will be able to better analyze and classify how a system works internally and will be able to put the different components in the block they belong to when you crack open a system.
In the next chapter, we will go through a system to learn how to map system functions and the functional blocks they belong to.
