A computer having 64bit processor Can have 64bit of operating system and
computer having 32Bit of processor can have 32Bit of Operating system. The
major difference between 32Bit Processor and 64Bit Processor is the number of
calculation per second they can perform. If it calculate more number in second
speed of completing task will increase.
Most of The computer made in 1990s were 32bit Os But now a
days computer comes with 64bit processor in which you can install 64bit
Operating System.
A 32Bit System can access 2^32 memory address that is 4GB of
RAM of Physical memory and 64 bit system can access 2^64 memory address. That is
greater than 4GB RAM it can Support.
Now a days 64bit Processor Comes With DualCore Quad Core
hexa Core, OctaCore. Multiple Core allow Computer to run faster its peformance
will increase having better processor power.
Advantages of 64Bit Processor:
In 64bit sysytem one can do multitasking users can switch
between various application without hainging computer.
Simply You can Say 64Bit Processors are more capable than
32bit processor because it can hold more data at once which can support more
than 4GB RAM while 32Bit Processor Support upto 4GB of RAM.
