The zip program puts one or more compressed files into a single zip archive, along with information about the files (name, path, date, time of last modification, protection, and check information to verify file integrity).
When a file is restored, it is given the same name, time of last modification, protection, and so on. If desired, it can even be put into the same directory in which it was originally located.
Can zip restore the file into the same inode as well? Briefly explain your answer.
For various values of I and X, compute the percentage of time that the program spends waiting for I/O and fill in the following table. If I and X are both 1 ms, for example, then the program spends 50% of its time waiting for I/O.
|100 ms||10 ms||1 ms||0.1 ms|
|25 ms (Data Center)|
|5 ms (HDD)|
|I||0.1 ms (SSD)|
|0.005 ms (PCM)|
|0.001 ms (RAM)|
