There are a variety of styles of reflecting telescopes, but I will describe one of the easier and more common designs. The primary mirror is curved concave. It is created typically out of thick glass that has been ground and polished to remarkable precision, which is then coated with reflective material. It can also be fashioned from a reflective metal.
A second, flat mirror (typically oval-shaped) is positioned at the focal point of the primary mirror at an angle to reflect the light into an eye piece. These are the major components: the curved primary mirror, the flat reflective mirror, and the eye piece, which is typically a magnifying lens.

The type of telescope is called a reflector. There are multiple subtypes of reflectors like a dobsonian, newtonian, RC, etc. Check out my youtube video on how to work with pictures taken from a telescope. youtu.be/M7-vLeVhM9g
A reflecting telescope uses a curved mirror to concentrate the light from distant stars, and is a very useful technique. There are very clever techniques and technicians, which can produce a mirror perfect over all its area, to within part of the wavelength of light!! The alternative method of using a glass lens, suffers from various difficulties, such as distortion and loss of light. You do not ordinarily consider focus in an astronomical telescope, for all the stellar objects are essentially at infinity.
A radio telescope is a reflecting telescope, and uses a mirror rather than a lens. Since radio waves are so much longer than light waves, the 'mirror' of a radio telescope is the 'dish' reflector that focuses radio waves onto its antenna, located at the prime focus of the dish.
A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]

The convex mirror curves outwards while the concave mirror would curve inwards. The convex mirror traces light out making faraway objects bigger like in a telescope.

The "resolving power" of a telescope is a measure of the ability of a telescope to distinguish between two separate objects that appear to be very close together in the sky.
