No, a keyboard is not the same as a piano, though the two share the same layout of keys. A piano makes sound with strings and hammers, while a keyboard or digital piano makes sound with electronics and speakers. A digital piano copies the piano layout and key action, but it is a different instrument that needs power.
How a piano makes sound
A piano makes sound when a key drives a hammer onto a string, and the string vibrates inside a wooden case. The harder the key is pressed, the harder the hammer strikes, and the louder the note sounds. Pedals change how long notes ring and how the strings respond, and the whole instrument is acoustic, with no power or speakers.
How a keyboard makes sound
A keyboard or digital piano makes sound with electronics: pressing a key triggers a stored sound or a synthesized tone, which comes out through built-in speakers or headphones. The instrument needs power, and it makes no sound with the power off. Touch-sensitive keys also respond to how hard a key is pressed, changing the loudness of the note.
Keys, pedals and size
A full piano has 88 keys, and many digital pianos match that count with 88 weighted keys. Pedals differ too: a piano has a sustain, soft and sostenuto pedal set, while a keyboard may have one pedal or a triple pedal set. A piano is a large piece of furniture that stays in one place, while a keyboard is portable and needs only a stand and a power socket.
Which one should you pick
Pick a piano when you want the acoustic sound and action of hammers and strings and have room for the instrument. Pick a keyboard or digital piano when you need headphones for private listening, portability, or extra sounds and recording features. A weighted 88-key digital piano is the closest match to a piano for a player who cannot keep an acoustic piano.

Frequently asked questions
Can a keyboard replace a piano?
For many players, yes: an 88-key weighted digital piano gives the same layout and key action, plus headphones for private listening. It cannot match the sound of strings and hammers, so a player who wants that sound still needs a piano.
Do keyboards have weighted keys?
Some do and some do not. Weighted keys copy the resistance of a piano action, while unweighted keys have less resistance. Check the key action before you buy.
Does a digital piano need tuning?
No. A digital piano holds its tuning because the sounds are stored, so it never needs a tuner. An acoustic piano drifts out of tune and needs regular tuning by a piano tuner.
Can I learn piano on a keyboard?
Yes, if it has 88 weighted keys, since the layout and key action match a piano. A smaller or unweighted keyboard still teaches the notes, but the key action differs from a piano.
