What is the minimum number of operations required, for a microprocessor with 8 data pins, to read a 32-bit word? Correct Answer 4

Consider the situation where a microprocessor gives an output of an 8-bit word. This is fed through an 8-bit digital-to-analog converter to a control valve. The control valve requires 6.0 V to be fully open.

A Windows 2000 Server computer named server2 runs numerous 32bit applications and two 16bit applications. Users start the 16bit applications by running APP1.EXE for one application and APP2.EXE for another application. The 16bit applications are configured to run in the separate memory space. You want to create a performance base like chart in the system monitor for all the applications on server2. You add all of 32bit applications and now you want to add two 16bit applications. What should you do?
