Assume a computer has the capacity to hold up to 6 memory modules, with each module containing 1G bytes.  How many bits are needed to address any byte in a module?  How many total bits are needed in the memory address? 

Compare and contrast Direct Memory Access (DMA) to program and interrupt driven I/O. 

Suppose you have a HDD with an average seek time of 10 msec and a rotational speed of 5400 RPM.  How long would it take to transfer 1M byte.  Assume 500 sectors on a track, and each sector contains 512 bytes. 

Explain in detail the primary components that comprise a Central Processing Unit. 

Suppose you have a HDD that with an average seek time of 8 msec and a rotational speed of 7200 RPM.  How long would it take to transfer 1M byte.  Assume 500 sectors on a track, and each sector contains 512 bytes.

  If the input is 12, what is the final value for numItems? int x;int numItems = 12;x = scnr.nextInt();if (x == 12) { numItems = 100;}else { numItems = 200;}numItems = numItems + 1;
