The command sudo lets you run a command as the root user without actually switching to the root user. In many cases this is safer than using the root user directly as only a single command is being run as root. For example, your normal user account would not be able the file /etc/fstab because it is owned by root. However, you can edit it with sudo like this:
sudo nano /etc/fstab
