Easy Rooting Your Android Device

After knowing a little more about my Android Smartphone, I continued learning more by installing Android optimization applications. After some searching at Google Play Store and found some interesting apps, I did the installation...and I didn't succeed. :( Most of the optimization programs can only be installed on a ROOTED device...well I got to learn about rooting my device then.
From googling, I knew that rooting is just like creating administrator account in windows system. Because I thought that giving myself administrator rights wouldn't be dangerous to my device, I started to collect anything needed for the process.
