DB2 has a very efficient and optimized backup utility that multiplexes the data pages it reads from the database and writes them to the target device in a randomized order.
DB2有一个非常高效的备份实用程序，它可以将从数据库读出的数据页分成多个部分，并以随机的顺序将它们写到目标设备。
Be careful though; the OS usually writes its own metadata to the beginning of a raw device, and you don't want to copy that.
不过要注意，OS通常将自己的元数据写在原始设备的开头，这些内容是不需要复制的。
This minimizes the number of small writes that are presented to the device, which in turn optimizes performance and helps extend the usable life of the drives.
这样能够减少设备的小型写操作的数量，从而优化了性能，并且有利于延长设备寿命。
In Listing 3, DB-Access reads the input from the standard input device, processes the input, and writes the results to the standard output device.
在清单3中，DB -Access从标准输入设备读取输入，然后在处理该输入后将结果写到标准输出设备。
For instance, on Mac OS X, the wall utility — short for "write all," because it writes a message to every physical or virtual terminal device — is setgid tty (as shown above).
例如，在MacOSX中，wall工具(“writeall”的缩写，因其会将某个消息写入所有物理或虚拟终端设备而得名)的setgid被设为tty(如上所示)。
The v, f, and p options specify verbose output (prints the files being added/extracted), writes/reads from a file (instead of a tape device), and retains permissions and ownership, respectively.
f和p选项分别指定输出详细信息（显示正在添加或提取的文件）、对文件（而不是磁带设备）进行写入/读取、保持权限和所有权。
Using the ps3fb device, your application writes to a main-memory (offscreen) buffer.
使用ps 3 fb设备，您的应用程序会写入主存(offscreen)缓冲区。
"For example, tilting a device can turn it into a steering wheel or a tabletop on which a marble rolls," writes CNET's Stephen Shankland describing the upcoming capabilities.
比如，倾斜设备可以把设备变成一个方向盘，或者让游戏中的桌面倾斜，让大理石球滚动起来。
For example, in Unix, devices appear to the application as files on the file system; meaning the application communicates with the device by performing file reads and writes.
例如，在Unix中，设备对于应用程序是作为文件系统上的文件出现的；意味着应用程序通过执行文件读写与设备通信。
