为确保尽可能少地丢失数据或完全不丢失数据(例如，在介质发生故障时)，备份与还原相当重要。
Backup and recovery is essential to ensure little or no data is lost, such as in the event of media failure.
语义建模技术，例如RDF，可以帮助简化对不同数据集之间自动进行推理所面临的问题，这些数据集是内嵌在数据存储介质中的。
Semantic modeling technologies, such as RDF, can help ease the problem of automatic reasoning between different data sets, provided that it is built-in to the data-store.
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。
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.
因此，您需要依靠其他存储介质来备份您的数据，比如，一个外部硬盘。
Thus, you may need to resort to some other medium, such as an external hard disk, to back up your user data.
该软件可以从包括多会话在内的不同类型的存储介质获取数据。
This can acquire date from various types of storage media including in multi-sessions.

而在交换机这一边，介质卡通过介质电缆接到服务器网卡上，把数据从服务器上传送到交换机主干网上。
A media card on the switch side connects to the server nic through a media cable and transfers data from the server to the switch backplane.
最后，信息理论关注的是，可以在给定的介质存储的数据量，从而处理如压缩和熵的概念。
Finally, information theory is concerned with the amount of data that can be stored on a given medium, and hence deals with concepts such as compression and entropy.
