Any computer that uses a 64 bit word length for memory and/or registers. It can be any specific machine architecture: Intel x86, PowerPC, Arm, Cray supercomputers, DEC VAX, DEC Alpha, IBM Z-series, etc. The important thing is that it process data in 64 bit words.
The main advantage of a 64 bit operating system is that it can make use of all the features and performance of a modern 64 bit microprocessor. If you run a 32 bit operating system on a modern 64 bit microprocessor the operating system will not be able to make use of any 64 bit features of the microprocessor and the performance will not be what the microprocessor is capable of.However a 64 bit operating system WILL NOT run at all on a 32 bit microprocessor (or one with a smaller word size) as the microprocessor does not implement the 64 bit features needed for the operating system to work.Note: in the not too distant future microprocessor manufacturers will release 128 bit microprocessors, which will require 128 bit operating systems to use all the features and performance of these microprocessors.

64 bit. the size of accumulator will always equal to the size of processor. e.g 32 bit processor has 32 bit accumulator.-------------------------------------------------------------------------------------------------------------------------------------------Actually on some computers the accumulator(s) are larger than the processor word size. Some examples are:IBM 704, IBM 709, IBM 7090, IBM 7094 - these are 36 bit processors with a 38 bit accumulatorIBM 7030 - this is a 64 bit processor with a 128 bit accumulatorSome computers do not have accumulator(s), these fall into three main groups:Variable word length machines that store all data in main memoryGeneral purpose register machinesStack machines that either have a fixed sized internal stack or a variable sized stack stored in main memory
The Snapdragon 712 is a mid-range 64-bit ARM LTE system.

x86-64 is 64 bit processing on 32-bit architecture,not to be confused with true 64 bit-processors like Itaniumhttp://en.wikipedia.org/wiki/X86-64
Both Windows and Unix based operating systems will continue to evolve with hardware. Currently, 64-bit architecture is becoming more common and will slowly replace 32-bit architecture. Given time, 128-bit architecture will likely replace 64-bit, and so on.
A server that has both a 64-bit CPU and a 64-bit data bus is better able to process and manage the large database files associated with Windows SharePoint Services 3.0.
64-bit refers to a processor with registers that store 64-bit numbers. A generalization would be to suggest that 64-bit architecture would double the amount of data a CPU can process per clock cycle. Users would note a performance increase because a 64-bit CPU can handle more memory and larger files. One of the most attractive features of 64-bit processors is the amount of memory the system can support. 64-bit architecture will allow systems to address up to 1 terabyte (1000GB) of memory
The storage capacity of a register is determined by the architecture. Thus they are 32 bits long on a 32-bit system and 64 bits long on a 64-bit system.

A computer architecture is how the processor processes the information. most new computers are 32 bit (I186) or 64 bit (X64).
It is a processor that works with 64 bit values instead of 32 bit values. The advantages are that it is much faster for operations on large 64 bit values for which a 32 bit processor would need multiple operations. This means that a 64 bit processor with the same clock speed can do more work in the same time.
Other than allowing you to reference much more ram then no. 64-bit will improve computational processing not your every day tasks. If you are trying to use finite element analysis software such as comsol for research than I would recommend the 64-bit architecture.
What is architecture?Architecture is the bit of the CPU (Central Processing Unit, or Processor) and/or software. The software can be an Operating System (such as Windows, MAC, or Linux) or even Video Games and other applications.The bit is the amount of data flow that goes through the CPU. Common bits today are 32-bit and 64-bit. If you have a 32-bit CPU, you MUST use a 32-bit OS (Operating System). If you have a 64-bit you can run BOTH 32-bit or 64-bit.What should you chose?If you have a 64-bit CPU, choose 64-bit. It can allocate more RAM (Random Access Memory) and can run both 32-bit and 64-bit software.Seeing x86?That is a 32-bit architecture. Why is it called this? I have no idea.What is a computer organization?When you install an OS, you are asked your name, and organization you work for. It is to register that computer in your name in case anyone needs to find out who it belongs to. If you don't have an organization you can put your address, or leave it blank.
It refers about the architecture of the operating system 32 bits only recognize 3.8 GB of RAM memory and 64 Can recognize more than 4 GB Of RAM memory, Talking About Windows 7
