1(a).Describe the von Neumann programmable machine model Von Neumann architecture is a picture model for a stored program digital electronic computer that uses a central Processing social unit (C.P.U.) and a exclusive sever storage structure -memory to hold some(prenominal) book of operating instructions and data. The central processing unit comprises of carry unit (C.U.) and arithmetic logic unit (A.L.U.)The A.L.U. operates on binary 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).

dead 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 uttermost data rate of 8mbps Has a data rate of 132 Mbps * Has a relatively large 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 unmatchable or more circular magnetic disk which ea ch or both surfaces are coated with a char! ismatic substance for recording data. Each surface has a read-write orchestrate that examines or alters the recorded data. Each platter is change virtue into thin concentric bands know as ledes. The tracks are marque 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 tack together to achieve the best exploit the memory has to keep up with the processor speeds.Fast, powerful CPUs read quick and easy admission fee to large...If you want to get a full essay, order it on our website: OrderCustomPaper.com
