A good starting point is to select the default (4 KB), especially if row sizes are fairly small or when access to the data is primarily random.
一开始的时候，可以选择默认选项(4KB)，如果行的长度很小，或者对数据的访问基本上是随机的，则更应该选择这一选项。
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。

In the next two articles, we'll explore the use of much more powerful and convenient data structures: ordered lists and random-access dictionaries.
在接下来两篇文章中，我们将探讨更强大、更方便的数据结构的应用：有序列表和随机访问字典。
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8KB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。
In stand-alone (non-networked) application environment, computer performance is largely determined by three components of the computer: CPU, the random access memory (RAM) and computer monitors.
在单机（非联网）应用环境下，计算机的性能很多程度上是有三个计算机部件所决定的：CPU，随即存取存储器（RAM）和计算机显示器。
Assume slower random data access rather than fast sequential access.
假定数据访问是较慢的随机访问而非较快的连续访问。
Then, he says, they could be just the thing for a superfast random access memory (RAM), the working memory that computers use to store data on the fly, and ultimately even for hard drives.
然后他又说他们适宜作随机储存器（RAM)电脑用来快速储存数据的储存器，而且最后可能会用于硬盘驱动器。
Random or serial access: will the tool move at random through the postmortem artifact, or will it access the contents serially?
随机或串行存储：工具采用随机还是串行方式访问后期工件？
As I mentioned in the overview section, random character access on a rope with many internal nodes is approximately o (log n), so traversal is o (n log n).
就像我在概述一节中提到过的，在拥有许多内部节点的rope上随机访问字符的时间大约为o (logn)，所以遍历时间为o (nlog n)。
One of the key design concepts behind Percolator was to provide random access to the repository to process documents individually, and thus avoiding the global processing required by MapReduce.
Percolator的一个关键设计理念是：提供对库中文档的随机访问，以实现对单个文档的处理，从而避免了像MapReduce那样对文档全集进行处理。
Most web applications want rapid random access to many pieces of indexed data.
大多数web应用需要对很多索引数据进行快速随机访问。
The Phase I grant supported a six-month effort to develop a low-power 'green' battery with a 30-plus year shelf life that will power a SRAM (static random access memory) circuit for a computer device.
阶段I合同为期6个月，开发一个低功率“绿色”电池，附带30年保存期限，为计算机设备SRAM(静态随机存取内存)电路提供动力。
A change that introduces some sort of index that allows access to random elements of the large retransmission queue is critical to address the find-first attacks against the TCP stack.
这个改变引入一些索引，允许对大的重传队列中的元素进行随机访问，这个改变对于解决TCP协议栈的find - first攻击问题很重要。
But in-memory implementations would allow random access, which is much more useful, especially for a generation of programmers used to DBMS and vendors needing to sell WYSIWYG systems.
但是内存中处理若可以通过随机访问来实现的话，这对尤其是用数据库管理系统的程序员和销售WYSIWYG systems的销售商的一代人是非常有用的。
A page blob supports up to 1 TB of data and is meant for random access.
而pageblob能支持最高1tb的数据，主要用于随机访问。
Volatile random access memory (RAM).
易失性随机访问存储器(RAM)。
While cramfs metadata is not compressed, cramfs USES zlib compression on a per-page basis to allow random page access (pages are decompressed upon access).
虽然cramfs元数据没有经过压缩，但是cramfs针对每个页面使用zlib压缩，从而允许随机的页面访问(访问时对页面进行解压缩)。
Load also includes commands for looping, random values, Posting dummy text, and access to 20 other test objects.
Load同样包含循环、随机值、发送“傻瓜”文本(一种毫无意义的，反复发送的文本，其用于测试)及访问其他20多个测试对象的命令。
Just two years earlier, IBM had also developed the first random access disk storage device, the random access Memory for Accounting and Control (RAMAC) 350, so there was a place to store this stuff.
就在两年前，IBM还开发了第一个随机访问磁盘存储设备，Random AccessMemoryforAccountingandControl (RAMAC) 350，所以有了存放这些东西的地方。
