Answer:
Here are the answers to the questions:
3.1 The two main elements of a CPU are:
The Control Unit (CU): The CU controls and coordinates the operations of the CPU. It is responsible for interpreting instructions and sequencing them for execution.
The Arithmetic Logic Unit (ALU): The ALU executes arithmetic and logical operations like addition, subtraction, AND, OR, etc. It contains registers that hold operands and results.
3.2 The fetch/execute cycle refers to the cycle of events where the CPU fetches instructions from memory, decodes them, and then executes them. The steps in the cycle are:
Fetch: The next instruction is fetched from memory.
Decode: The instruction is decoded to determine what it is asking the CPU to do.
Execute: The CPU executes the instruction. This could involve accessing data, performing calculations, storing results, etc.
Go back to Fetch: The cycle continues as the next instruction is fetched.
3.3 The binary number 00000011 is equal to the decimal number 3.
Binary: 00000011
Decimal: 1 + 2 = 3
So the conversion of the binary number 00000011 to decimal is 3.
