A cascode amplifier has
 
  A) a common-drain in series with a common-gate
  B) a common-emiiter in series with a common-collector
  C) any of the above
  D) a common-source in series with a common-gate

Question 2

What is interrupt-driven I/O and what is its major advantage?
 
  A) An I/O device needing service sends a request to the PIC (programmable interrupt controller), which in turn notifies the CPU of the request based on the assigned priority level of the specific I/O device. If there are no pending I/O requests the CPU does not have to spend time checking the I/O ports.
  B) Each individual I/O device is checked sequentially on a regular basis to see if it needs to be serviced. This slows down the CPU operation.
  C) Individual I/O devices regularly send inquiries to the CPU to see if it is available for a specific I/O operation; if the CPU is available, the I/O device then proceeds to carry out its operation.
  D) Each individual I/O device is serviced sequentially on a regular basis by the PIC. This speeds up the I/O process.
