Q1:

Which is not part of the execution unit (EU)?

A Arithmetic logic unit (ALU)

B Clock

C General registers

D Flags

ANS:B - Clock

The EU receives program instruction codes and data from the BIU, executes these instructions, and store the results in the general registers. By passing the data back to the BIU, data can also be stored in a memory location or written to an output device. Note that the EU has no connection to the system buses. It receives and outputs all its data through the BIU.
