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



short 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 maximum data rate of 8mbps Has a data rate of 132 Mbps
* Has a relatively large slot 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) disc storage medium
A hard disc consists of one or more circular magnetic disk which either or both surfaces are coated with
a Magnetic substance for recording data. Each surface has a read-write head that examines or
alters the recorded data. Each platter is change integrity into thin concentric bands known as tracks. The
tracks are make 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 order to achieve the best exploit the memory has to keep up with the processor
speeds.Fast, powerful CPUs read quick and easy access to large...If you want to get a full essay, order it on our website: Ordercustompaper.com
