1(a).Describe the von Neumann programmable machine model Von Neumann architecture is a picture model for a stored program digital computing machine that uses a central Processing building block (C.P.U.) and a single(a) sever storage structure -memory to hold twain book of operating instructions and data. The central processing unit comprises of look into 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).

briefly 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) criminal record storage medium A hard disc consists of law or more circular magnetic disk which all or both surfaces are coated with a ! magnetic substance for recording data. Each surface has a read-write thinker that examines or alters the recorded data. Each platter is change integrity into thin concentric bands know as tethers. The tracks are base 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 set to achieve the best exploit the memory has to keep up with the processor speeds.Fast, powerful CPUs read quick and easy entranceway to large...If you want to get a full essay, order it on our website: OrderCustomPaper.com
