(Operating System)

1.) Your system has an SSD as its primary disk. Of FCFS, SSTF and SCAN, which would be the most efficient disk scheduling algorithm? Why?

2.) Your filesystem uses inodes for storing metadata. You have just opened a file called fred. In which place(s) would the name be stored?

a.) in the directory metadata b.) in the file itself c.) in the file metadata d.) in the open file table e.) none of the above

3.) You are designing your the filesystem of your operating system. Your system needs to support under 5,000 users, it is expected that each user will average about 100 files. Why would a single level directory structure be inappropriate?

4.) You are designing your own file system and you are trying to decide whether or not to allow hard links. If you do allow them, youll need to keep some additional data. What data and why?

5.) In Unix type filesystems, the superblock stores metadata describing the filesystem. What type if information would be stored?
