what exactly is feedback? why do i get it from a guitar? is there a way that it can it be prevented without purchasing any devices?

In laymans terms, feedback is when sound bounces back and forth from your guitar to your amp at high frequencies. It is a harmonic squeal, and not desirable. To prevent it, dont stand too close to your amp, or reduce volume a little.
