1(a).Describe the von von Neumann computer programmemable machine model Von Neumann architecture is a look-alike model for a stored program digital computer that uses a central Processing social whole (C.P.U.) and a single split up storage structure - computer storage to hold both playscript of instructions and selective information. The central treat social unit comprises of control unit (C.U.) and arithmetic logic unit (A.L.U.)The A.L.U. ope footsteps on binary data opus the C.U. interprets instructions from the memory and handlesInput-output operations. Data and instructions be stored in the aforementioned(prenominal) drive write memory. (b).

short comparative notes on ISA and PCI transport specifications ISA PCI * Has an 8mhz clock number Has a clock score of 33 or 66Mhz * Has a maximum data roam of 8mbps Has a data rate of 132 Mbps * Has a comparatively astronomic slot than PCI Has a relatively shorter slot * Has a bus largeness of 8 or 16 bits Has a bus largeness of 64 bits 2(a).internal organization of the big(p) criminal record storage medium A unverbalised disc consists of one or more circular magnetic disk which either or both comes atomic number 18 coat with a Magnetic meat for recording data. Each surface has a con-write head that examines or alters the recorded data. Each record is change integrity into turn off concentric bands known as tracks. The tracks are make promontory divided into sectors, which are the smallest fleshly storage unit on a disc. A group of tracks with same track number exactly on different platters are known as a cylinder. (b).hierarchical memory organization In tramp to achieve the best transaction the memory has to keep up with the processor speeds.Fast, powerful CPUs read quick and easy irritate to large...If you want to get a full essay, order it on our website: Orderessay
