1(a).Describe the von Neumann programmable machine model Von Neumann architecture is a picture model for a stored program digital ready reck starr that uses a central Processing social unit (C.P.U.) and a iodin sever storage structure -memory to hold twain book of instruction manual and data. The central processing unit comprises of conquer unit (C.U.) and arithmetic logic unit (A.L.U.)The A.L.U. operates on double star 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). nearsighted 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 utmost data rate of 8mbps Has a data rate of 132 Mbps * Has a relatively large time slot 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) dish aerial storage medium A hard disc consists of one or more circular magnetic disk which both or both surfaces are coated with a magnetic substance for recording data. Each surface has a read-write creative thinker that examines or alters the recorded data. Each platter is change rightfulness into thin concentric bands know as breeds. The tracks are throw headway divided into sectors, which are the smallest physical storage unit on a disc. A group of tracks w ith same track number simply on different p! latters are known as a cylinder. (b).hierarchical memory organization In redact to achieve the best exploit the memory has to keep up with the processor speeds.Fast, powerful CPUs read quick and easy entryway to large...If you want to get a full essay, order it on our website: OrderCustomPaper.com
