a refractor has an objective lense at one end and an eyepiece at the other. The light from an object passes through the objective lense, is focused upon the eyepiece, which focuses the image for your eye.
A reflector uses a mirror to gather light, then focus it on an eyepiece which focuses the image for your eye.
A computerized telescope is merely one which uses input on a keypad to point the telescope at the object you want to view. The computer usually has a list of thousands of stars, planets, galaxies, etc to which it can be pointed. The computerized scopes have to be pre-aimed at a couple of points in the sky, unless they are equipped with gps capability. In that case, you set up the scope, tell it to point at Jupiter and it will move to point at Jupiter (assuming that Jupiter is above the horizon.)

A refractor uses a curved lens which the light passes through while a reflector uses a curved mirror that the light bounces off of without passing through. That refers to the objective; all telescopes use a refracting eyepiece.
Both types of telescopes can be mounted on a computer controlled mounting. A computerized telescope is just a normal telescope on a computer controlled mounting so that the computer can tell you where to point it, or actually point it for you with motors. It takes the work (and the fun and the romance) out of astronomy.

A reflector uses a mirror to gather light, a refractor uses a lens and a computerized telescope has one or more motors in its mount which are controlled by a computer to follow the stars and select coordinates in the sky without user interaction.

a refractor telescope is the type of telescope in binoculars and stuff like that. it uses a lens an an object to form the image.
a reflector telescope is the one with all the different lenses, it uses them to reflect light and form an image.
& a i have no clue what a computerized telescope is, but i think it's just a telescope operated by a computer?
