There are two types of operating system architecture available for Windows and Linux operating system. 32-bit and 64-bit operating system.
32 - bit Operating System
32-bit operating system measn it can process 32 bit of data in one CPU cycle. So if yo have a DUAL Core CPU with 2.0 GHz speed then it can process 119.21 GB per second.
CPU speed 2.0 GHz = 2000000000 Hz
CPU is Dual Core so frequency is doubled
2 X 2000000000 Hz = 4000000000 Hz
Operating system can process 32 bit per CPU cycle
4000000000 Hz X 32 bit = 128000000000 bit per second
128000000000 bit / 1073741824 bit = 119.21 GB
64 - bit Operating System
64-bit operating system means it can process 64 bit of data in one CPU cycle. So if yo have a DUAL Core CPU with 2.0 GHz speed then it can process 238.42 GB per second.
CPU speed 2.0 GHz = 2000000000 Hz
CPU is Dual Core so frequency is doubled
2 X 2000000000 Hz = 4000000000 Hz
Operating system can process 64 bit per CPU cycle
4000000000 Hz X 64 bit = 256000000000 bit per second
256000000000 bit / 1073741824 bit = 238.42 GB
Difference is clear. A 64 bit Operating System can process 2 times more than a 32 bit Operating System. Now the obvious question is why we need a 32 bit Operating System ? Answer is straight forward. 32 bit Operating System is old Operating system supported for old CPU where architecture is designed to process 32 bit per CPU cycle. Now a day CPUs are build on top of 64 bit architecture and it require a 64 bit operating system. In some cases it is possible to install a 32 bit operating system in a 64 bit CPU but in that case 32 bit is always idea or in other words that CPU will always run with only 50% load.
To know what operating system architecture is installed on your manchine type the following command in your command prompt. (Command prompt must run with administrator rights)
And you will get the result like this depends upon your operating system.
OSArchitecture
64-bit
Alternatively you can go right click on "My Computer" => Go to "Properties" under system block you will find "System type". This is you operating system architecture.
