Question: what are the main differences between a 32bit operating system and a 64bit operating system?
Answer: A 32-bit system can access 232 memory addresses, i.e 4 GB of RAM or physical memory. A 64-bit system can access 264 memory addresses, i.e actually 18-Quintillion bytes of RAM. In short, any amount of memory greater than 4 GB can be easily handled by it.
