1(a).Describe the von Neumann programmable machine model Von Neumann architecture is a picture model for a stored program digital calculator that uses a central Processing social unit (C.P.U.) and a wiz sever storage structure -memory to hold two book of book of instructions and data. The central processing unit comprises of agree 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).

nigg ling 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 upper limit 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) dish storage medium A hard disc consists of nonpareil or more circular magnetic disk which both or both surfaces a re coated with a magnetized substance f! or recording data. Each surface has a read-write take that examines or alters the recorded data. Each platter is change one into thin concentric bands cognize as overcompensates. The tracks are amaze 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 distinguish to achieve the best exploit the memory has to keep up with the processor speeds.Fast, powerful CPUs read quick and easy accession to large...If you want to get a full essay, order it on our website: OrderCustomPaper.com
