Several links have been broken so th at for the next day or two, what was formerly a contiguous area 0 has been broken into two parts. However, both parts of area 0 have working links into area 1 using routers with RID 1.1.1.1 and 2.2.2.2. Which answers list the command on the router with RID 1.1.1.1 to create a virtual link to help solve this temporary problem?()
一个文件有100个磁盘块,假设文件控制块在内存(如果文件采用索引分配(indexedallocation),索引表也在内存)。在下列情况下,请计算在contiguous,linked,indexed(single-level)三种分配方式下,分别需要多少次磁盘I/O操作?(每读出或写入一个磁盘块都需要一次磁盘I/O操作)(10%) 假设在contiguous分配方式下,文件头部无空闲的磁盘块,但文件尾部有空闲的磁盘块。假设要增加的块信息存放在内存中。 1.在文件开始处添加一个磁盘块; 2.在文件结尾处添加一个磁盘块; 3.在文件中间删除第50块磁盘块;(假设磁盘块编号从0—99) 4.在文件第50块前添加一个磁盘块;(假设磁盘块编号从0—99)
