A geostationary satellite (geo-sat for short) is a satellite that appears to stay stationary over one geographic spot.
Currently, all geo-sats orbit around the equator, taking exactly 24 hours to go around the Earth. Meanwhile, the Earth is also turning once every 24 hours -- so the satellite and the Earth keep pace with each other.

A geostationary satellite is one where the satellite stays at one point over the earth. This is done by having the satellite in an orbit that is the same speed as the earth is turning (approx. 22,500 miles up at the equator). It is used for things like communications and satellite TV.

A geosynchronous satellite is a satellite whose orbital track on the Earth repeats regularly over points on the Earth over time. If such a satellite's orbit lies over the equator, it is called a geostationary satellite. The orbits of the satellites are known as the geosynchronous orbit and geostationary orbit. Another type of geosynchronous orbit is the Tundra elliptical orbit.

How about INMARSATs? International Marine communication satellites that have revolutionized communications between ships and between ship and shore, so that Morse Code is no longer used in ship communications. Another group of these are Geostationary Weather Satellites. Then there are the Television Direct Broadcast satellites, and on and on.

All the above answers are good answers. I would like to add that geostationary satellite must be place along the equatorial plane.

It is a satellite that stays above the same point on the earth's surface. That means it orbits the earth once every 24 hours.

It is a satellite in synchronous orbit. In other words, it orbits at exactly the same speed as the earth turns beneath it, so that from the ground it appears to be locked in one position.

a satellite that stays over the same spot on the earth, that is, its period is one day. All telecommunications satellites are geostationary.

To be precise, the term "geostationary" describes only circular one-day orbits above the equator. Other one-day orbits should be termed "geosynchronous".

One which appears stationary (or nearly so) from the surface of the earth. Occurs when a satellite's orbit is ~22,500 mi high→ T = 1 day.
