Options: (A)A computer architecture where all processors have direct access to common physical memory (B) It refers to network based memory access for physical memory that is not common (C) Parallel tasks typically need to exchange data. There are several ways this can be accomplished, such as through, a shared memory bus or over a network, however the actual event of data exchange is commonly referred to as communications regardless of the method employe(D) (D) None of these
Why is the width of the data bus so important to the processing speed of a computer?
Options: The narrower it is, the greater the computer's processing speed, The wider it is, the more data that can fit into main memory, The wider it is, the greater the computer's processing speed, The wider it is, the slower the computer's processing speed
