In a Symmetric Multiprocessor $($SMP$)$ all CPUs $.....$

can only work in pairs, so the must be an even number of them

are peers and execute the same operating system

are located symmetrically over the memory bus

are in a master$-$slave relationship

execute the same operating system, but only one is in charge with initiating $\frac{\text{I}}{O}$ operations for all processes
