Most linux systems support multiple users, most of which have limited "permissions" they can only do certain things. There is a "super user" (usually "root") which can do anything. There is a command called "su" which stands for set user, which changes a terminal to a different user. If you don't give a user it changes to root, which usually requires a special password, but is also somewhat of a security danger. sudo stands for set user do, it implements an su, then runs the one command, then goes back to the original user. If the user is added to a special group you don't need a password to run a sudo. This is the way CSOS is setup, the "fedora" user can run sudo without a password. So pretty much anything which requires modifying system files needs to be run with sudo.
