A "32-bit version" refers to a type of computer architecture that uses 32 bits to represent data and memory addresses. This means it can handle a maximum of 4 gigabytes of RAM, as 2^32 equals 4,294,967,296. Most operating systems and applications designed for 32-bit systems are optimized to work within this memory limit. Many older computers and software applications are built on this architecture, including some versions of Windows and Linux. While 32-bit systems are still in use, they are gradually being replaced by 64-bit versions, which can manage significantly more memory and improve performance for modern applications.
