What is the difference between 32 bit and 64 bit operating systems?

Ankur Kulhari

A 64-bit operating system can move 64 bits of data per clock cycle. A 32-bit operating system can move only 32 bits of data per clock cycle.
A 64-bit OS is better than 32-bit because:

  • It effectively doubles system capabilities if the system is running a 64-bit processor.
  • More information can be sent at one time on a 64-bit system than on a 32-bit system.
  • Data intensive programs can be executed more efficiently on 64-bit then 32-bit.
  • A 32-bit application can be run on a 64-bit operating system.
