Since a DB2 buffer pool is a part of the main memory of the system, the DB2 database manager allocates it for caching tables and index data when it reads or writes to and from media disks.

因为db2缓冲池是系统主内存的一部分，DB 2数据库管理器在它读取或写入磁盘介质时将它分配给缓存表和索引数据。

Note that you can use the sync command to flush the buffer cache out to the storage media (force all unwritten data out to the device drivers and, subsequently, to the storage device).

注意，可以使用sync命令将缓冲区缓存中的请求发送到存储媒体(迫使所有未写的数据发送到设备驱动程序，进而发送到存储设备)。

The sender starts by reading media data, such as video frames, into a buffer from which encoded frames are produced. In the Managed Rtp Library, the RtpSender is used for:.

发送方从读取媒体数据开始，比如视频桢，到缓冲里，此原始数据再编码为编码桢。
