Once information is processed by the CPU, the information goes out in the form of images, video, sound, and text to output devices, like the printer or monitor.

"A liquid crystal display has two transparent surfaces that are placed on either side of of a layer of cells containing tiny crystals" (Pearson, 2017). "Electrical signals sent to the crystals cause them to form images on the surface" (Pearson, 2017).

The central processing unit is the brains of the computer. The CPU processes the input from keyboards, mouse, and digital cameras into output. There are 4 kinds of output. They are the following: text, graphics, video. and sound The output devices in which the information is displayed can be the monitor or printer. Computers process information in electrical pulses. Each electrical pulse contains an instruction received from random access memory. The clock speed of a CPU is measured in mega hertz or gigahertz. This means that a computer can process millions or billions of instructions per second. The instructions are carried to the CPU from RAM through electrical impulses.
