It serves the same purpose as a mouse but it is designed with a move-able ball on the top, which can be rolled in any direction.
A trackball can be useful for persons who get pain in their wrists after long stints at the computer, especially if they are using the standard mouses. When the mouse is held in a ‘claw-like’ position, it causes your palm to be parallel to the desk, and it keeps your forearm in a perpetually twisted state. Twisting your wrist to the left or right as you point and click, can cause further stress. And that’s where the trackball comes in. The trackball, completely stationary, lets you dial in a comfortable, relaxed position and keeps it all day, while simultaneously freeing up your desk for mugs, post-its, chargers — whatever you want. https://padlet.com/referrals/samueldemar11]]> 2020-05-13 14:50:11 UTC https://padlet.com/denniew/hgu8nront20aftyb/wish/570295414 Sound card KalebJohn https://padlet.com/denniew/hgu8nront20aftyb/wish/570347748 A sound card is a card like device that is grooved and controls the audio, it is also both an input and output .This device can be useful for doing slide shows with a projector or for a DJ that uses a computer so he can amplify his sound by connecting to a loud speaker.]]> 2020-05-13 15:06:41 UTC https://padlet.com/denniew/hgu8nront20aftyb/wish/570347748 MICR Timon2a2 https://padlet.com/denniew/hgu8nront20aftyb/wish/570357065  MICR which means Magnetic Ink Character Recognition is an input device .

A microphone is a device that captures audio by converting sound waves into an electrical signal. This signal can be amplified as an analog signal or may be converted to a digital signal, which can be processed by a computer or other digital audio device.


While all microphones (or "mics") serve the same basic function, they can capture audio in several different ways.
