在大部分情况中，如果您希望可以使用更高级的库(举例来说，使用stdio，而不是原始的读写操作)，就应该这样做；这可以帮您更好地回避这些问题。
In most cases, if what you want can be done with a higher-level library (stdio instead of raw reads and writes, for instance), you should do that; it gives you more insulation from possible quirks.
可能有一个请求执行一个简单的算术活动，另一个请求执行一个资源密集型操作，比如数据库读写。
You could have one request perform a simple arithmetic activity and another request perform a resource intensive operation, such as reading or writing to a database.
如果成功地连接到数据库，这个函数会返回一个连接对象，后续的数据库读写操作需要使用这个对象。
Upon successfully connecting to the database, this function returns a connection object, which is required in the subsequent database read and write operations.
例如，一个系统可能无法从访问控制的角度区分读写操作，而另一些系统则可以对此进行区分。

理想的情况是，线程数量等于处理器的数量，不过这也要求任何线程都不应该执行诸如同步读写、等待事件通知等阻塞型的操作，以免线程阻塞。
The ideal number is one per processor, but that implies that none of these threads should execute a blocking operation such as a synchronous read/write or a wait on an event.
如果您熟悉磁盘结构，就知道磁盘是被分解成扇区的，大小通常是512字节；所有读写操作均在成倍大小的扇区中进行。
If you're familiar with disk structure, you know that disks are broken down into sectors, which are normally 512 bytes in size; all read or write operations occur in multiples of the sector size.
文件系统就算把硬盘格式化成系统可以读写操作的一种“表”结构。
A file system is a formatting of the disk into a table that the operating system can read, interpret, and write to.
而对原始设备的访问则没有缓存，导致物理设备上的直接读写操作。
An access to a raw device avoids the cache, resulting in direct read and write operations on the physical device.
在存储区域中，LUN通常表示一个主机能够执行读写操作的SCSI磁盘。
In a storage area, a LUN often represents a SCSI disk on which a host can perform a read and write operation.
如果服务器出现故障，客户机api软件将把缓存读写操作重新路由到正常运行的备用服务器上。
If servers fail, the client API software reroutes your cache reads and writes to a working alternate.
CloudWatch使亚马逊的用户可以了解到资源使用、操作性能和总体需求状况，包括CPU使用、磁盘读写和网络流量等指标。
CloudWatch gives Amazon customers visibility into resource use, operational performance, and overall demand patterns, including metrics such as CPU use, disk reads and writes, and network traffic.
之所以将这种技术称之为 “开销较低的读-写锁” 是因为您使用了不同的同步机制进行读写操作。
The reason this technique is called the "cheap read-write lock" is that you are using different synchronization mechanisms for reads and writes.
这个工具可以指出在特定时间点发生了多少读写操作，以及磁盘控制器的饱和程度有多大。
This tool tells you how many reads and writes are happening at a particular point in time and how saturated your disk controllers are.
DRBD软件为用户读写操作提供主服务器和辅助服务器之间的同步操作，以及其他同步操。
The DRBD software provides synchronization between the primary and secondary servers for user-based Read and Write operations as well as other synchronization operations.
随着程序对该文件进行读写操作，AIX内核将该文件的数据作为非计算性的永久存储分页在内存中进行缓存。
As a program does reads and writes to the file, the AIX kernel caches the file's data in memory as non-computational permanent storage pages.
通常，象在套接字之间进行读写之类的操作都是阻塞操作。
Typically, operations such as reading and writing across sockets are blocking operations.
像对变量的读写这样的操作，在线程中是根据所谓的“程序顺序”——程序的语义声明它们应当发生的顺序——排序的。
Actions, such as reads and writes of variables, are ordered within a thread according to what is called the "program order" — the order in which the semantics of the program say they should occur.
这就保证了服务的质量和性能，并完全解除了单实例数据库与读写个人信息操作之间的耦合。
This allows the grid to service these with the usual grid quality of service and performance and it completely decouples the single instance database from the read and write profile operations.
仔细检查函数中所有使用的变量，如果有一个变量不是当前作用域定义的，而且使用了不止一次，那么我们就应该把这个变量保存在局部变量中，而使用这个局部变量来进行读写操作。
Watch the variables being used in a function. If you notice a function using an out-of-scope variable more than once, store it in a local variable and use that instead.
