We are surrounded by electronic devices that make the modern world work. Almost all of these devices and the systems they run are “Embedded Systems”, which are small purpose-built computers designed to solve specific problems. These computers don’t look like what most people think of as a computer; they don’t have a keyboard, mouse nor monitor. They might even be hidden in normal, everyday objects that you use around the house. The reality is that many of the more powerful embedded systems are running Linux and any “smart devices” around your home or work are almost certainly running embedded Linux.
