共享记忆体是指同一块记忆体区段被一个以上的行程所分享。这是我们所知速度最快的行程间通讯方式。使用共享记忆体在使用多CPU的机器上，会使机器发挥较佳的效能。-shared memory is with a memory segment was more than one trip to share. We know this is the fastest means of communication between the itinerary. The use of shared memory in the use of multi-CPU machines, machines will play better efficiency.

linux默认情况下，Linux可以使用6个虚拟控制台来登录本地Linux (本地终端) 系统，当然，这个设置是可以修改的(修改文件/etc/inittab)。每一个虚拟控制台允许让一个用户登录，我们可以使用 ALT+Fn(n=1,2,3,4,5,6)来登录或者是切换到某个虚拟控制台，它们分别对应tty1到tty6虚拟终端。-linux by default, Linux can use 6 virtual consoles to log in local Linux (local terminal) system, of course, this setting can be amended (to modify the file/etc/inittab). Each virtual console to allow a user log, we can use ALT+ Fn (n = 1,2,3,4,5,6) to log in or switch to a virtual console, tty1 they correspond to tty6 virtual terminal.
