Random-Sequential Access的意思|示意

By looking at the read and write sequence counts in detail, you can further determine if the access is sequential or random.

通过仔细地观察读写序列计数，可以进一步确定访问是顺序的还是随机的。

For example, with typical page sizes of 8 KB or 16 KB, in-page processing is inherently sequential and less CPU-efficient than random data access.

例如，对于典型的8 KB或16 KB的页面，页内处理天性是连续的，CPU效率低于随机数据访问。

You'll even examine some file system attributes, such as sequential and random access, which can affect performance.

甚至还将研究一些可能影响性能的文件系统属性，比如顺序访问和随机访问。

It allows you to use low-level routines, high-level ISAM routines, or the ODBC layer for high-speed random or sequential data access.

它允许你使用低水平程序，高水平IS AM程序，或者用于高速随机或者连续数据访问的ODBC层。

Since it is not using high speed spinning disks as storage media like traditional hard disks, SSD obtains much higher sequential and random access speed than traditional hard disks.

由于它不是以高速旋转的磁盘作为存储介质，数据读写时不需要寻道时间，因此它有着传统硬盘不可比拟的顺序和随机存储速度。

As a result, the disk access time is much longer when reading data in random order than when reading in sequential order.

因此，与按顺序读取相比，按随机顺序读取数据时的磁盘访问时间要长得多。
