1(a).Describe the von Neumann programmable machine model Von Neumann architecture is a picture model for a stored program digital calculating machine that uses a central Processing building block (C.P.U.) and a individual sever storage structure -memory to hold some(prenominal) book of instruction manual and data. The central processing unit comprises of ascendance unit (C.U.) and arithmetic logic unit (A.L.U.)The A.L.U. operates on binary program data opus the C.U. interprets instructions from the memory and handlesInput-output operations. Data and instructions are stored in the same read write memory. (b).

bypass comparative notes on ISA and PCI transport specifications ISA PCI * Has an 8mhz clock rate Has a clock rate of 33 or 66Mhz * Has a maximum data rate of 8mbps Has a data rate of 132 Mbps * Has a relatively large schedule than PCI Has a relatively shorter slot * Has a bus width of 8 or 16 bits Has a bus width of 64 bits 2(a).internal organization of the big(p) discus storage medium A hard disc consists of star or more circular magnetic disk whi ch any or both surfaces are coated with a! charismatic substance for recording data. Each surface has a read-write liberty chit that examines or alters the recorded data. Each platter is change fairness into thin concentric bands cognise as handles. The tracks are perk up headway divided into sectors, which are the smallest physical storage unit on a disc. A group of tracks with same track number simply on different platters are known as a cylinder. (b).hierarchical memory organization In wander to achieve the best exploit the memory has to keep up with the processor speeds.Fast, powerful CPUs read quick and easy entranceway to large...If you want to get a full essay, order it on our website: OrderCustomPaper.com
