探测器又叫做缓冲区探测器—它只在实际的数据块上被调用，比如视频帧。
The probe is what's called a buffer probe-it gets called only on actual blocks of data such as frames of video.
当ship缓冲区为空时，SHIP逻辑将另一个'Fetch '请求发送到“US ”服务器，以便获取下一块数据。
When the SHIP buffer is empty, the SHIP logic sends another 'Fetch' request to the "US" server to get the next block of data.
copy _ from_user函数将数据块从用户空间复制到内核缓冲区。
The copy_from_user function copies a block of data from user space into a kernel buffer.
顾名思义，MailBox从本质上说就是Drop，用于在检测之前保存数据块的单槽缓冲区。
As its name implies, MailBox is essentially the Drop by itself, a single-slot buffer that holds a piece of data until it has been retrieved.
缓冲区缓存——为存储从物理数据文件读取的数据块而分配的内存。
Buffer Cache - Memory allocated for storing data blocks read from physical data files.
溢出是指数据被添加到分配给该缓冲区的内存块之外。
An overflow occurs when data is added to the buffer outside the block of memory allocated to the buffer.
然后，联邦服务器上的SHIP逻辑发送'Fetch '请求，以便读取来自被发送到“ US ”数据源的查询的一块数据，并将数据放入ship缓冲区。
The SHIP logic on the federated server then sends' Fetch 'requests to read a block of data from the result of the query sent to the "US" data source and places the data into the SHIP buffer.
缓冲区缓存为存储从物理数据文件读取的数据块而分配的内存。
Buffer Cache Memory allocated for storing data blocks read from physical data files.
该控制器从外部重写装置接收数据块并将其存储在第一个缓冲区。
The controller receives a data block from an external rewriting device to store it in the first buffer.
是更快的写一大块的数据一次硬盘然后编写大量的小块。 缓冲区用于积累这些块。
The efficient way to write to a device is to write a bigger chunk of data at a time.
存储在第一个缓冲区的数据块传输到第二个缓冲区。
The data block stored in the first buffer is transferred to the second buffer.
让我们考虑硬盘作为输出设备。写入硬盘内存相比非常缓慢。是更快的写一大块的数据一次硬盘然后编写大量的小块。缓冲区用于积累这些块。
The output device might be a hard disk, for instance, and writing to the hard disk involved moving the write head around and waiting for the platter to spin to the right place.
对应用数据分块，使得数据块大小符合通信子网mtu有效负载的要求，避免IP层分片需要重新分配缓冲区、计算校验和以及数据复制的费时操作。
Therefore, it can reduce one time data handling, 3 divide application data into blocks that content the demand of effective load of communication subnet MTU to avoid IP fragments.
