32-bit or 64-bit is the number of data bits that a computer can handle in a register, with the data bus, with an instruction manipulation, etc. In a "standard" 8-bit per byte system, 32 bits can hold four bytes, and 64 bits can hold 8 bytes.
The designations 32-bit and 64-bit also refer to the operating mode of the processor. The IA-32 architecture, which started with the 80386 microprocessor, could handle 32-bit data and it had a 32-bit address bus. That is a 4GB address space, of which 2GB is used for the program, 1GB is used for shared DLL's, and 1GB is used for the operating system.
While a 32-bit address space is quite large, some programs, particularly database programs, need to manuipulate more than 2GB without needing to "think" about address segmentation.
The 64-bit architecture solves this by allowing much larger address spaces to be created, up to 8TB, depending on the operating system. The operating system runs in 64-bit mode, and it supports programs written in both 64-bit mode and 32-bit mode.

AMD64
Steps needed to upgrade Windows to support 64-bit processing?
To use 64-bit specific applications, you must purchase both a 64-bit processor and a 64-bit version of Windows. 64-bit applications will not run on 32-bit versions of Windows, even if a 64-bit capable processor is installed. You also cannot install a 64-bit version of Windows on a 32-bit only processor.
What term does amd use to describe a processor using a 64 bit instruction set with 32 bit internal core processing?
What term does AMD use to describe the processor technology that uses a 64 - bit instruction set with 32 - bit internal core processing
What must software developers do to take advantage of a 64 -bit processor such as the Itanium?
Software developers must recompile their applications to use 64-bit processing and write operating systems that use 64-bit data transfers
What is the difference between 32 bit and a 64 bit system?
It means the processing size is twice as much in the 64-bit. So there is a greater speed of data transfer (10% to 15% more).

What must software developers do to take advantage of a 64-bit processor?
To take advantage of a 64-bit processor, such as the Intel Itantium or the AMD Athlon, software developers must recompile their applications to use 64-bit processing and write operating systems that use 64-bit data transfers. Microsoft provides a 64-bit version of Windows XP tha works with 64-bit processors.
What does 64 bit ready mean?
'64-bit ready' means the computer has the capabilities, maybe with or without modifications, to utilize a 64-bit processor, 64-bit operating system, 64-bit code, and more than 4GB of RAM.
