当从硬盘驱动器读写表和索引数据时,DB 2使用缓冲池来缓存它们。
DB2 USES buffer pools to cache the table and index data as they are being read or written to the hard disk drive.
这指的是驱动器上可用的缓存数,以及用于读写数据的算法集。
This is the amount of cache available on the drive, as well as the set of algorithms that are used to read and write data.
Jungle Disk的备份功能很强,还可以与其它读写网络驱动器的应用程序同时协作。
Jungle Disk is great at backup, but you can also use it with any application you'd like that can write to a network drive.
And this is because as you start writing--saving files to your hard drive, what happens is you might save this file here, then this one, then this one, then this one, but very reasonably you might go back eventually and delete this one.
这是因为当你开始对硬盘驱动器进行读写时,你可以保存一个文件到磁盘的某处,然后再一个,再一个,又一个,最后你可能回到这,并删除这一个文件。
