Assume that two studentw have been assigned the task of selecting a computer for a family doctor's office. Student A has selected a reduced instruction set computer $($RISC$),$ while student B proposed to use a multiprocessor computer. Student A$\text{'}$s assumption is that the doctor's office does not have enough complicated tasks to require a device that has multiprocessor's and supports multiprocessing and parallel processing. Student B$\text{'}$s assumption is the opposite; the family doctor's office will often need to support multiple tasks, such as printing bills, receiving faxes and e$-$mails, staying connected to remote sites to access patient's data through a wide area network $($WAN$)$ interface, displaying patient's X$-$ray images, supporting the front desk's patient data entry and appointment management, and billing operations. Student Bcomputer that has multiple central processing units $($CPUs$)$ to support
