Where is plasma found in modern technologies?

As we see from the question category, plasma has more than one meaning. In physics, it refers to a gas that is heated to the point of ionization. The sun is made of plasma, and fires contain some plasma. Every time a person uses fire, they are also using plasma. There are types of lights that use plasma, and televisions that use these lights to create pictures. And there is also another meaning, which is the blood component other than the blood cells. Plasma has medical uses, to use in transfusions when there is not enough whole blood available of the correct blood type (or when you can't determine the blood type).
