X-rays are commonly produced by accelerating (or decelerating) charged particles; examples include a beam of electrons striking a metal plate in an X-ray tube and a circulating beam of electrons in a synchrotron particle accelerator or storage ring.
Examine your computer for jacks and ports that support your audio device. The location of certain jacks and ports will vary depending on your computer's make and model. For example, most jacks on a desktop computer will be located in the back; whereas jacks on a laptop computer are usually located on its sides.
Line-in and line-out jacks work in opposite fashion in all audio devices. In the case of computers, the ports connect directly to the sound processor or sound card of the computer. Moreover, one can reduce the volume and configure other settings at the line-in and line-out level, especially in computers.
