Final answer:
The given pseudocode is an example of a conditional statement in computer programming. It checks whether the firstNumber is bigger than the secondNumber and executes different statements based on the result.
Step-by-step explanation:
The given pseudocode is an example of a conditional statement in computer programming.
In this case, the condition being checked is whether the firstNumber is bigger than the secondNumber. If the condition is true, the statement in the 'then' block will be executed (print 'A firstNumber'). Otherwise, if the condition is false, the statement in the 'else' block will be executed (print 'secondNumber').
Conditional statements are commonly used in programming to make decisions based on certain conditions, which can help control the flow of the program.
