In quiet corners, I may roam, Silent explorer in your digital home. I follow your hand with easy grace, A tiny navigator in cyberspace.

In corners dark where dust may creep, A silken net where insects leap, A whisper's thread, In shadows spread, A home where tiny spiders sleep.

I have two mouths and a throat, an interstellar road. To use me is to destroy me, at least, that's the theory.

I’m something you can copy perfectly, yet the original never disappears. I get smaller when you compress me, but smarter when you train me. I live in layers, travel in packets, and die when corrupted. People argue whether I should be free.

Pronounced as one letter, And written with three, Two letters there are, And two only in me. I’m double, I’m single, I’m black, blue, and gray, I’m read from both ends, And the same either way. What am I?
