What is Hacking?

This is my first post in this section and i consider my audience are completely newbies or may have some knowledge about Hacking etc . But this is just an Introduction post . I will cover all the topics from basics to expert level. I will gradually move up in this field but patience is the source to learn Hacking , readers should have patience :-) "As Slow and Steady wins the race". 

So Hacking is basically gaining access to any computer system with the permission of the owner. It is an Illegal act and may cause you into big trouble. Hacking is done for fun , or to take revenge from someone , or there could be many reasons.

In computer network security Hacking is modifying the features of a system and to completely takeover it. Hacking is the on moving topic nowadays but still many of you may/ may not be aware of all of its reasons , purpose and many more (will be discussed in later posts).
