When a process waits for a block device data request to complete, it incurs I/O wait time, and all idle time becomes wait time.
当一个过程等待一个块设备数据请求完成时，它会增加 I/O等待时间，而所有空闲都会变成等待时间。
RDBMS designers concentrated on optimizing I/O and tried to align the data access patterns with the block structure imposed by the drives.
RDBMS设计者的精力主要集中于优化I/O和设法用驱动器的块结构来安排数据访问模式。
The block I/O buffer (kiobuf) in the 2.6 kernel allows I/O requests larger than PAGE_SIZE.
在 2.6 中块I/O缓冲区（kiobuf）允许 I/O请求可以比 PAGE_SIZE大。
Node also claims that it will never deadlock, since there are no locks allowed, and it doesn't directly block for I/O calls.
Node声称它绝不会死锁，因为它根本不允许使用锁，它不会直接阻塞I/O调用。
Patrick o 'connor 31, a student electrician who lives in the neighbouring block of flats, said: "I am shocked."
31岁的电工学徒帕特里克·奥科诺尔(Patricko' Connor)住在附近的一栋公寓楼。他说：“我很震惊。”
The Block I/O Layer in the 2.6 kernel has been rewritten to improve kernel scalability and performance.
内核中的块I/O层被重写，以提高内核的可扩展性和性能。
And so I've done a little bit different things here which is I put the accept part of the block with I o error.
所以我这里在处理部分，所做的同io错误，有一点不一样，这表明什么。
That says it's in here. It's in this tri-block. It raised an exception, but it wasn't and I O error.
这在这里它是一个try程序块,它报出异常，但他不是io错误。
The data block sizes should be a multiple of the operating system's block size within the maximum limit to avoidunnecessary I/O.
数据块大小应该是一个多个操作系统的块大小以最大限度的避免不必要的 I / O。
Summarization about calculator circuits based on 4 bit embeded system is given, include block diagram and work principle, the instruction system, the structure of MCU core and the I/O.
对基于4位嵌入式微控制器的计算器电路进行了综述，包括功能框图与工作原理、指令系统、内核硬件结构以及系统与外界接口等。
So, use no block I/O application without access to the equipment is polling, and block access can be similar to "break" replaced the asynchronous notification.
这样，使用无阻塞I/O的应用程序无须轮询设备是否可访问，而阻塞访问也可以被类似“中断”的异步通知所取代。
Multiple sector mode aka IDE Block Mode, is a feature of most modern IDE hard drives, permitting the transfer of multiple sectors per I/O interrupt, rather than the usual one sector per interrupt.
多扇区模式和IDE块模式一样，是最新的IDE硬盘的特征，允许在每个I/O中断时采用多扇区传送而不是通常的单扇区传送。
