Yes and no!  My definition of embedded systems is that it is a single-purpose computer that cannot be modified by users. This is designed and built for one purpose,and your users cannot "install other applications" on it (unless you hack it).
PCs &amp; smartphones &amp; tablets,on the other hand,are "multipurpose computers",where you can install whatever application you want,you can even write it yourself &amp; run it.

Yes,Embedded Systems tend to be 'smaller' in terms of the scale of the computing resources contained in each. Your microwave oven may only have a few hundred bytes of RAM and a few Kbytes of code and a small 4-bit or 8-bit microcontroller in it,for example. Your DSLRs and paper printers are more luxurious with lots of Mbytes of RAM &amp; code (code that continues to be refined and developed by DSLR &amp; printer manufacturers on each successive model) and 32-bit CPUs,maybe multi-core CPUs today,and lots of hardware Other image processing ASIC. Thousands of satellites in each orbit have 1 and only 1 job to do - designed by the designer,and that's all he will do; no application can be installed by the user,fortunately,all users are safe on the surface hundreds of kilometers away.

But all the computers,with the CPU,sometimes the GPU,RAM,ROM,Flash storage &amp; / or hard drive,and various other application-specific hardware. Sometimes there are Operating Systems like Linux (or sometimes Windows / CE),more often there will be RTOS - Real-Time Operating Systems,which are rather simpler than Linux,and sometimes there are no OSes,no RTOS,only the code runs on 'bare metal' hardware that is responsible for everything itself. The programs (usually 1 and only 1) they run are usually written in C,maybe C ++ or part of that,although more and more other high-level languages find their way into the Embedded System (which we might regret in time,but that other problem…).
