What are the different strings of a guitar and how are they tuned?

A guitar has six strings, named E, A, D, G, B, and E. The strings are tuned to specific pitches by tightening or loosening the tuning pegs. The standard tuning for a guitar is EADGBE, with the thickest string (low E) tuned to E and the thinnest string (high E) also tuned to E.
