查询词典 read-only memory

Long int readData(Buffer * pBuffer,/* pointer to the abstract buffer */ byte * pOutput,/* pointer to the output byte array */ long int offset,/* offset of the output byte array */ long int arrayLength /* size of available output byte array */){ while (there is something more to read and there is room for output){ read from the first memory block; if (the first memory block is empty){ delete the first memory block from the linked list and free its memory

在 清单 5 中，该函数销毁性地从 pBuffer 所指向的抽象缓冲区最多读取 arrayLength 个前导字节，并在内存块变为空时从链表中删除它们，然后返回成功读取的字节数目。如果需要，您可以实现一个类似 readData 的函数来允许非销毁性的读取。实现一个函数来返回当前存储在抽象缓冲区中的字节数目，这样可能会带来好处。清单 6。返回抽象缓冲区中的字节数目

If the disk is infected with the virus, the memory is read the first part of the virus program, it has been modified after the control of the size of memory space available in high-end memory think of a region, and moved to the first part of the area, and then read on the disk "bad cluster" in the second part of the first part and to put together, so that all proceedings on the presence of the virus in memory of the high-end, and then modify the interrupt vector INT13H or other interrupt vector to the high-end virus program, then you can read the original boot memory and the control over to it to complete the system startup.

如果是染上病毒的盘，读到内存的是病毒程序的第一部分，它得到控制权后修改内存可用空间的大小，在内存高端辟出一块区域，并把第一部分移至该区，接着读入放在磁盘"坏簇"中的第二部分，并和第一部分拼起来，使病毒程序全部驻留在内存的高端，然后修改INT13H的中断向量或其它中断向量，使其向高端的病毒程序，这时即可把原引导程序读到内存中，并把控制权交给它以完成系统的启动。

To imagine such a situation, when you more than the amount of memory, and run a relatively large-scale process, will inevitably lead to a sharp reduction in the number of physical memory, and in this case the so-called "optimization software," the beginning of smart aleck, the data memory for paging to the hard drive, and the procedures needed for the operation of the data, which may have led to at the same time, the "optimization of software" tried to data paging to the hard disk, and the operating system attempts to read data from the hard disk into memory, a very large increase in hard drive read and write.

想象这种情况，当你内存数量不多，而又运行了比较大型的程序后，必然导致物理内存数急剧减少，而在这种情况下所谓的"优化软件"开始自作聪明，把占用内存的数据往硬盘上进行分页，而程序的运行需要这些数据，这可能导致了在同一时间内，"优化软件"试图将数据分页到硬盘，而操作系统试图将数据从硬盘读取到内存，极大增加了硬盘的读写。
