Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Who is "he"? You can run passwd as root instead of as itudja. Use "sudo passwd itudja" to change itudja's password. You can configure sudo to use your own password instead of root's. Some distro's are configured that way by default.
sudo is used to execute a program as the root user. You need to enter the password to show that you're authorised to run as root. If you didn't have to enter the password anyone could use sudo to do anything on the system and destroy the OS.
It allows itudja to run as root without a password. Why do you want to do that. It's dangerous. What's wrong with entering your own password or root's (depending on how sudo is configured) to change itudja's password. It's a one time deal. Why introduce a huge security risk just. You had to enter the root password to run "visdo" anyway.
