)A device that draws pictures on paper based on commands from a computer. Plotters differ from printers in that they draw lines using a pen. As a result, they can produce continuous lines, whereas printers can only simulate lines by printing a closely spaced series of dots. Multicolor plotters use different-colored pens to draw different colors. In general, plotters are considerably more expensive than printers.
A hiccup (/ËhÉªkÉpËËhÉªkÊp/ HIK-Ép, HIK-up; also spelled hiccough) is an involuntary contraction (myoclonic jerk) of the diaphragm that may repeat several times per minute. In medicine, it is known as synchronous diaphragmatic flutter (SDF), or singultus, Latin for the act of catching one's breath while sobbing.
Hiccups are sudden, involuntary contractions (spasms) of the diaphragm muscle. When the muscle spasms, the vocal cords snap shut, producing the hiccup sound. Hiccups are often rhythmic. They are usually just a temporary minor annoyance, but prolonged hiccups may signal a major medical problem. The longest recorded hiccup attack is six decades! Women and men tend to get hiccups equally as often, but hiccups that last more than 48 hours are more common in men.
