A geostationary orbit will keep the satellite in one area relative to the surface
A geostationary satellite appears to stand still to a viewer anywhere on the earth, not just on the equator.

If you mean what it is used for, its most common uses are for weather forecasting, and communications, like satellite TV and radio.
It appears to remain in the same spot above the earth.

A geostationary satellite does not trace a path over the surface of the earth because that is what geostationary means - the satellite is stationary over a point on the Earth.

Geostationary satellites are in an orbit that's 22,282 mi (35,786 km) above the surface of the Earth. For more on Geostationary satellite orbits, visit http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx

No. A geostationary satellite appears to be stationary in the sky, which means not moving. This is a big part of the reason why it is referred to as a geo'stationary' satellite.
It should be possible to have the perfectly geostationary satellites. But it is not possible. Perfectly geostationary satellite can not be made. Such satellite is pulled away by other objects like moon, sun and other planets from different directions. This force changes the velocity of the satellites.
