1(a).Describe the von Neumann programmable machine model Von Neumann architecture is a picture model for a stored program digital ready reck building blockaryr that uses a central Processing unit (C.P.U.) and a single(a) sever storage structure -memory to hold both book of instructions and data. The central processing unit comprises of check off unit (C.U.) and arithmetic logic unit (A.L.U.)The A.L.U. operates on binary 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).

small 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 supreme data rate of 8mbps Has a data rate of 132 Mbps * Has a relatively large one-armed bandit 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) discus storage medium A hard disc consists of one or more circular magnetic disk which all or both sur faces are coated with a charismatic subs! tance for recording data. Each surface has a read-write read/write head that examines or alters the recorded data. Each platter is change honor into thin concentric bands cognise as leashs. The tracks are pull back 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 golf club to achieve the best exploit the memory has to keep up with the processor speeds.Fast, powerful CPUs read quick and easy nark to large...If you want to get a full essay, order it on our website: OrderCustomPaper.com
