How to Find Bus Architecture on Your Computer
The bus architecture of your computer is the general setup of the computer buses (the paths along which data is transferred between hardware units). This information is readily available (and changeable) through the use of the BIOS, the low-level operating system that controls almost everything on your computer. While changing your bus architecture is a bad idea unless you are technically experienced, merely checking the figures will cause no problems.
