    OS X is based on Unix, which is a multiuser system. To manage this Unix uses file ownership and permissions.
    Every file on the system has some permissions to define who can do what with the file. There are three groups -
    1.user owner
    2.group owner
    3.others
    and the permissions are
    1.read
    2.write
    3.execute
    User is someone having an account on OSx
    Group is just a group of users. Every user has to have atleast 1 group.
    So a file permission would tell what a user, group and others can do with the file.
    Anyways sometimes when you are installing some stuff, or running some applications, some important file permissions get changed. I dont know why but mostly the installers screw it up I guess.
    Once they get changed, things go crappy, program would quit on you, your prefernce wont be rememberd and other things. So repairing permissions takes care of that
    BOy, it became lengthy,.
    anyways hope it helps
    cheers
