Question: what is difference between kali linux 32 bit and 64 bit?
Answer: The difference is that a 32-bit system can process 32 bits in one cycle, similar a 64-bit system can process 64 bits in one cycle. The major difference is that in a 32-bit system you will be able to use only 2^32 bytes of RAM which is around 4GB. Similarly, for 64-bit systems, you can use up-to 16 Exa-Bytes of RAM.
