Most of us are likely aware of the major multitasking operating system that manage our computers. These complex pieces of software are designed for powerful hardware and easily capable of running many programs at once, since their OS prioritize hardware tasks that requests known as the system calls and allocate them processing time or memory space as needed and chances are you have already chosen a favorite one that make things like pocket-sized devices take any power about the unique electronic systems like the ones found in cars.
Even high minded robots that will eventually defeat humanity don’t do these things and need some sort of operating system. Let’s talk about the ones designed for battery powered devices like phones and tablets. These might seem like they should be very different from a desktop OS, but to the incredible performance of modern mobile processors. Top mobile OS including iOS and Android are multitasking operating systems capable of balancing multiple background tasks and user input with grace and poise usually but it hasn’t always been this way in the early days of mobile computing battery life and performance were much plentiful than they are today.
The embedded operating systems were examples in which being Windows and Mac OS, they had limited functionality and could not handle one task at a time. In today’s standards they’d be considered pretty useless phone but they tell that they were essential for these strange device. Even though the days of pocket PCs are behind us embedded OS are still essential for many other low powered limited functionality devices like media players, video cameras, GPS units, fancy dishwashers or even the networking router which is currently allowing you to enjoy video at certain times through such as when dealing with heavy machinery. Systems need to process requests quick and reliably.
