Question
1. The cycle time of a processor with a 1 GHz clock rate is ___________ nanosecond(s).
2. Which of the following CPU components fetches an instruction from a register, increments the instruction pointer, decodes the instruction, and stores the decoded components in individual registers?
Gate
Branch prediction unit
Decoding Unit
Arithmetic-logic unit
Control Unit
Primary Storage
3. Select one or more of the following statements that are true about branch prediction and speculative execution.
Branch prediction and speculative execution are mutually exclusive design features. A CPU can implement one or the other but not both.
If a conditional branch prediction is later found to be incorrect, partial and complete results from speculatively executed instructions must be discarded.
Speculative execution is only required/relevant if multiple CPU stages and register sets are provided.
For conditional BRANCHes within a program loop, the CPU keeps track of prediction successes and failures to improve the accuracy of later predictions
4. A(n) _____________________ is a simple circuit that can perform a primitive processing function such as NOT, AND, OR, or NAND.
5. When an instruction is decoded, the _________________and one or more operands are extracted and stored in separate registers.

Please Note: According to the Chegg Answering Guidelines, as the post contain more than One Question, I have answered the first question here. For receiving the answer to the rest of the Questions, please Re-post for the other Questions.
Q1) Answer)
As we know,
clock rate = 1 / clock cycle time
1 GHz = 1 / clock cycle time
clock cycle time = 1 / 1 ghz
= 1 / 1000000000
= 0.000000001
= 1 nanosecond
Thus The cycle time of a processor with a 1 GHz clock rate is 1 nanosecond.
