Which of the following is a Boolean expression? Select all that apply: 3==4, 3!=4, 3+4==7, True, 'False', 3+4. Select all the options that can fill in the blank in the following sentence: Main/primary memory is/has ______________ than secondary memory.
Understand the Problem
The question is asking which of several statements are considered Boolean expressions, and it also asks to fill in the blank in a statement about memory types. The first part requires knowledge of Boolean logic, while the second part tests understanding of memory architecture.
Answer
Boolean: 3==4, 3!=4, 3+4==7, True. Memory: faster, less capacity.
The Boolean expressions are: 3==4, 3!=4, 3+4==7, and True. Main/primary memory is typically faster and has less capacity than secondary memory.
Answer for screen readers
The Boolean expressions are: 3==4, 3!=4, 3+4==7, and True. Main/primary memory is typically faster and has less capacity than secondary memory.
More Information
Boolean expressions evaluate to True or False. Main memory (RAM) is generally faster but has less storage capacity than secondary memory (like hard drives).
Tips
A common mistake is thinking any expression with numbers is Boolean; only those that use comparison operators or are actual Boolean values are Boolean.
