It is important to make a distinction between symmetric and asymmetric multiprocessing algorithms. What are the benefits of using several processors in a single programme, as well as the drawbacks of doing so?

Explain in further detail the major differences between symmetric and asymmetric multiprocessing. What are the advantages and disadvantages of employing many processors in a single program?

Then, what is the definition of an overlay? When it comes to supercomputers, why is the usage of overlays no longer necessary?

In generall, computers think in terms of numbers (i.e. binary data). Thus, any operation performed in the computer must be done using either mathematical or logical operations. Given this inherit limitation of computers, what is the compare instruction actually doing when we, as assembly programmers, provide two numbers for it to "compare"? Furthermore, what assembly instruction is similar to the compare instruction? How are the two instructions different?
