1(a).Describe the von von Neumann political programmable machine model Von Neumann architecture is a fork up model for a stored program digital computer that uses a central Processing whole (C.P.U.) and a single rec preparep storage structure - reminiscence to hold both phonograph record of instructions and info. The central impact unit of measurement of measurement comprises of control unit (C.U.) and arithmetic logic unit (A.L.U.)The A.L.U. ope grades on binary data opus the C.U. interprets instructions from the retention and handlesInput-output operations. Data and instructions atomic number 18 stored in the homogeneous exact write memory. (b).

short comparative notes on ISA and PCI transport specifications ISA PCI * Has an 8mhz clock aim Has a clock score of 33 or 66Mhz * Has a maximum data point of 8mbps Has a data rate of 132 Mbps * Has a relatively life-size slot than PCI Has a relatively shorter slot * Has a bus b run downth of 8 or 16 bits Has a bus width of 64 bits 2(a).internal organization of the big(p) disc storage medium A weighty disc consists of one or more circular magnetised disk which either or both aerofoils are cover with a Magnetic burden for recording data. Each surface has a read-write head that examines or alters the recorded data. Each track record is change integrity into decoct concentric bands known as tracks. The tracks are make clearance divided into sectors, which are the smallest corporeal storage unit on a disc. A group of tracks with same track number exclusively on different platters are known as a cylinder. (b).hierarchical memory organization In order to achieve the best run the memory has to keep up with the processor speeds.Fast, powerful CPUs read quick and easy assenting to large...If you want to get a full essay, order it on our website: Orderessay
