A read-out is the information a computer or a machine gives you and shows on a screen — a number, a short result, a value. The speed on a car display, the temperature on a hospital monitor, the total that flashes up at the shop: those are read-outs. Older machines printed a read-out on paper; now it is almost always on a screen. Though actually, in everyday talk most people just say the screen or the numbers. Read-out (also written readout, one word) belongs more to technical and news English. It is not the same as reading a text out loud. That is read out as two words, a verb.
