journaled file system可以replay其log以确保file system是一致的,但是在继续操作之前,它仍应验证其他数据结构。由于完整file system检查的复杂性,因此通常实现一个单独的程序,即file system检查程序。对file system进行完全验证可能会花费大量时间,尤其是遇到比较大的volume时。幸运的是,只有当superblock指示该volume dirty...
相关知识点: 试题来源: 解析 C By sending too much data to a specific area of memory, adjacent memory locations are overwritten, which causes a security issue because the program in the overwritten memory location is affected.反馈 收藏
As a result, the buffer is always partially filled and the consumer sits idle most of the time. The result is that overall the system underperforms, both in terms of idle time and wasted memory: We have a few ways to solve this problem. The first way is to use a smaller buffer. At...

A buffer is a continuous storage space in the operating system memory. A buffer overflow occurs when the data written by a program to the buffer exceeds the limit of the buffer and overwrites the adjacent memory space. Buffer overflow is a dangerous vuln
As another example, when printing a document, when the PRINT command is invoked by the system or the application, the print data is sent to the buffer and is then transferred to the printer. From there, the printer accesses the information. This frees the computer up to do other tasks whi...
