The unceasing quest of human mind has conceived to almost all crucial inventions of the world. Hacking dates back its inception to the same human urge to know and hence explore things. Hacking is a practice of peeping into the extreme technical details of any computer application, program, or the whole system in order to extend its capabilities or alter its functionalities. People who rightly follow this practice of hacking are termed as ‘hackers’. A hacker’s vision towards solving any technical problem is undoubtedly beyond the perception of any normal computer expert.
