1.4. Flags

Try these first

1. 1.

   What is the purpose of flags in a CPU?

   Hint

   Think about how decisions are made in programming.

2. 2.

   Describes what a conditional instruction is.

   Hint

   Consider how decision-making is represented in programming languages.

3. 3.

   What is a flag in computer architecture?

   • A type of instruction
   • A status indicator
   • An execution path

   Hint

   Consider what provides information about CPU state.

4. 4.

   True or False: Conditional instructions can change the flow of execution based on flag conditions.

   • True
   • False

   Hint

   Think about how decisions are made in programming.

5. 5.

   Given the following sequence of operations: A=10, B=5, perform A-B. If the resulting flag states are 'Zero' and 'Carry,' describe the flow of execution in a hypothetical program.

   Hint

   Focus on what happens with the subtraction and how flags affect program control.

6. 6.

   Create a conditional instruction sequence for a loop that increments a counter until it reaches 10. Describe how flags are used in this loop.

   Hint

   Visualize the purpose of the flags at each iteration.
