Document Summary
Nfs=network file system file system=the way a disk is formatted and how data is stored on a disk. A sector is a fixed size (512 bytes) regardless of where on the disk the sector resides. Master boot record(mbr)=sector 0 of the disk and it boots the os cluster/data block=file storage on the os that uses a number of sectors. Journaling file systems(jfs)= m keeps a journal of transactions so that if a crash happens the system can rebuild the file system, developed to resolve the problem of a computer shutdown with open files. Raid=(random array of inexpensive disks) refers to the recovery of a system given a disk failure. You can give either the owner, group, or others read, write, and execute privileges. The owner can change the permissions of the file by using the chmod command. There are two ways that this can be done.
