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。
The large graphic files, in uncompressed format, can consume enormous disk space and the amount of bandwidth, thus slowing down access time.
大的未压缩格式的图形文件可以消耗掉大量的磁盘空间和带宽量，从而延缓了访问时间。
These units do not translate directly to time; they represent relative time for a typical disk access.
这些单元不直接转换成时间；它们表示的是典型磁盘访问的相对时间。
The computer spent most of its time idle while auxiliary operations such as disk access were completing.
在完成辅助操作，例如磁盘访问，的同时，计算机花费大量时间处于空闲状态。
When data are contiguous, the time used to access data on the disk is minimized and the database server can read data faster.
当数据连续时，用于访问磁盘上数据的时间最少，数据库服务器可以更快地读取数据。
To reduce database contention independent of making disk configuration changes, try approaches that may reduce database access contention or improve file access time.
如果希望减少数据库争用，但是不愿意修改磁盘配置，那么应该尝试减少数据库访问争用或改进文件访问时间的措施。
When the first data management systems emerged in the 1960s, disk drives were the only place to store and access large amounts of data in a reasonable time.
当 20 世纪 60年代数据管理系统刚刚出现时，磁盘驱动器是唯一可以在合理时间内存储和访问大量数据的地方 。
Unless you measure carefully, you don't know the true average access time or throughput of your disk subsystems.
除非您仔细检查，否则您无法知道磁盘子系统实际的平均存取时间或吞吐量。
DB2 row compression features can decrease disk storage requirements while at the same time improve sequential read access of large queries which perform full table scans.
DB 2行压缩功能可以减少磁盘存储需求，同时改进执行全表扫描的大量查询的顺序读取访问。
At the same time, you can create a system in which files are automatically converted when added to a particular directory on disk-useful for FTP interaction or for access through a CIFS file share.
同时，还可以创建一个系统，在这个系统中当文件被添加到磁盘上的一个特定的目录时可自动实现转换，这个对于FTP交互或通过一个CIFS文件共享访问文件非常有用。
The reservations guarantee access to time-multiplexed system resources (CPU, network, or disk bandwidth).
这种机制保证了对时分复用（time-multiplexed）系统资源的访问（CPU、网络或磁盘带宽）。
Disk performance can be measured in terms of several important characteristics: seek time, latency, access time, and the spin speed of the disk.
磁盘性能，可衡量的几个重要方面的特点：寻找时间，等待时间，存取时间，速度和旋转的磁盘。
The reason that this process takes so long is that a computer's operating system must be loaded from its hard disk into its random-access memory (RAM) every time the machine is turned on.
这个过程花这么长时间的原因是，每当打开计算机时，计算机的操作系统必须从硬盘载入到随机存取存储器(RAM)。
At the same time, other threads can access disk files or get data from a communications port.
同时，其他的执行绪可以存取磁碟档案或从通讯连接埠取得资料。
