The companions have given you good information; although the word "jinete" is very generical (rider) allow me to add something more referring to that period in Spain...
The troops of the Military Orders (Calatrava, Santiago, Montesa...etc) were composed of the "
frailes caballeros "(friars knights) who integrated the heavy cavalry or spears, had three mounts and were the elite corps; then there were the "
frailes soldados" (friars soldiers) who were the light cavalry and had only one mount; then there were the vassals of their jurisdiction, recruited in the different "encomiendas" of the order were "
caballeros villanos" (villain knights). In any document, villain designates any inhabitant of a "villa" (small village), indistinctly of its type. They were armed with a not very long javelin spear that rushed from top to bottom and could also carry several "azagayas" or javelins. Therefore, the "villain knight" or "brown knight" was the inhabitant of a village that possesses horse and weapons, the villain knights gained privileges and became legally equivalent to the "infanzones", the low nobility, although of course without title. The "villain knights" of the border areas were in charge of organizing the militias of the "concejo" (council) when it was necessary to do so.
Light cavalry ("
cavalls alforrats in Aragón Crown") was used in exploration missions, reconnaissance and on the formation flanks. The formations were "en tropel", which was a formation of little front and very deep, normally this type of formation was used in the flanks or wings.
The Muslim armies did not differ much from the Christians. The light riders carried several "azzagayas" or javelins, and bows that threw the enemy in successive charges. The heavy ones carried lance (rumh) of up to 5 meters. A woman's handkerchief could be tied as a banner, a typically romantic Arab idea, which later spread to medieval Europe. The Arab horsemen carried two swords, a short Arab sword and a longer blade inherited from the Sassanid cavalry, they could also carry a double-edged arzon axe ("tabarzin" of "tabar" which is an axe and "zin" which is a horse) and some a mace (dabbus).
In the battle the preferred tactic was that of "Karr wa-farr", which literally means charge and retreat, used attacks followed by sudden retreats in order to break down enemy formations, in order to settle the final blow when they had lost their cohesion. The Christians called it torna-fuye.
Another tactic used was that of envelopment, the forces of the "ayanahaim" or flanks, which were normally light cavalry, enveloped the large adversary and attacked him from the flanks and rear.
