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.
