What does a 32-bit system and a 64-bit system mean?

The history of computer development is from the previous 8-bit, 16-bit to the first 32-bit and 64-bit, the number of digits is one of the important criteria used to measure the performance of a computer, and the number of digits determines the maximum capacity of the computer, the maximum length of the file, the transmission speed of the data inside the computer, the processing speed and the precision.

The 32-bit system refers to the 32-bit CPU design in the operating system, is 32 processor one-time processing 32 bits is 4 bytes of data, and 64 system is the operating system for 64-bit CPU design, is a one-time can handle 64 bit is 8 bytes, here in the same frequency of work under the premise, 64-bit CPU processing speed is one-fold higher than 32-bit. Of course, this is just one of the 32-bit systems and 64-bit systems, and the small weave is not talking about it. (Refer to: 32-bit and 64-bit difference is what, 64-bit system has any advantage)

How can I see if your computer is 32-bit or 64-bit?

1, Win7 System, directly right click on the desktop "Computer" and then select the "Properties" option. This allows you to view the configuration of your computer's system on the open window. 32 does not show, 64 of the only display. As shown in the figure:

2, of course, also through a number of cmd command to execute, "start-run" in the input "winver", if your system is 64-bit, will be clearly marked "x64 Edition."
