What is the difference between a "32-bit" and "64-bit" operating system in terms of memory addressing?
Correct! Well done.
Incorrect.
The correct answer is A) A 32-bit OS can typically address up to about 4 GB of RAM, while a 64-bit OS can address vastly more memory, often into the terabytes
A
Correct Answer
A 32-bit OS can typically address up to about 4 GB of RAM, while a 64-bit OS can address vastly more memory, often into the terabytes
Explanation
The address width determines the maximum number of unique memory locations a system can reference; 2^32 addresses (about 4 billion) limits 32-bit systems to roughly 4 GB, while 64-bit systems support a vastly larger range.
