Suitable mounts come in two basic varieties--equatorial and altazimuth. An equatorial mount allows motion in two directions: north-south and east-west.
An altazimuth (altitude-azimuth) mount, by contrast, permits up-down (altitude) and left-right (azimuth) motions.
A motorized telescope on a computerized altazimuth mount can track celestial objects as accurately as one on an equatorial mount.
A telescope on an altazimuth mount simply moves up-down (altitude) and left-right (azimuth).
