x86_64
uname is a command used to print system information x86_64 means 64bit operating system, i686,i386 means 32 bit.
[ If your CPU is 64 bit machine then it will support both 32bit & 64bit operating system, But If your machine[CPU] is 32bit it will support only 32bit operating system not 64bit ]
