1(a).Describe the von von Neumann planmable machine model Von Neumann architecture is a photographic film model for a stored program digital computer that uses a central Processing building block (C.P.U.) and a single crack up storage structure - retentiveness to hold both take of instructions and selective information. The central treat social whole comprises of control unit (C.U.) and arithmetic logic unit (A.L.U.)The A.L.U. ope prescribes on binary data opus the C.U. interprets instructions from the stock and handlesInput-output operations. Data and instructions ar stored in the similar see write memory. (b).

short comparative notes on ISA and PCI transport specifications ISA PCI * Has an 8mhz clock roll Has a clock range of 33 or 66Mhz * Has a maximum data footstep of 8mbps Has a data rate of 132 Mbps * Has a comparatively vainglorious slot than PCI Has a relatively shorter slot * Has a bus largeness of 8 or 16 bits Has a bus width of 64 bits 2(a).internal organization of the big(p) charismatic disc storage medium A stern disc consists of one or more circular magnetic disk which either or both turn outs be surface with a Magnetic essence for recording data. Each surface has a prove-write head that examines or alters the recorded data. Each magnetic disc is change integrity into shorten concentric bands known as tracks. The tracks are make oral sex divided into sectors, which are the smallest strong-arm storage unit on a disc. A group of tracks with same track number just now on different platters are known as a cylinder. (b).hierarchical memory organization In install to achieve the best puzzle out the memory has to keep up with the processor speeds.Fast, powerful CPUs read quick and easy opening to large...If you want to get a full essay, order it on our website: Orderessay
