[Star Trek] Why are the Borg so dangerous?

I have a question about the Borg, why are the Borg so terrifying and dangerous? Is it possible to defeat the Borg?

They're dangerous because they have an overriding directive to assimilate other species' technology and biology into the collective. If you resist being assimilated, you're an enemy. Also, they are hard to fight because they can alter their technology on the fly to counter nearly any kind of weapons, armor, or shields they encounter.
