The intensity of bad breath differs during the day, due to eating certain foods (such as garlic, onions, meat, fish, and cheese), obesity, smoking, and alcohol consumption. Since the mouth is exposed to less oxygen and is inactive during the night, the odor is usually worse upon awakening (morning breath).
DVI (Digital Visual Interface) is a specification created by the Digital Display Working Group (DDWG) to accommodate analog and digital monitors with a single connector.
The main difference between these two is that VGA is an analog standard while DVI is digital. DVI is next logical step for connecting your computer and monitor.Video signals are originally digital signals but are converted into analog before leaving the GPU of your computer through the VGA port.VGA was created because all of the monitors at that time are based on CRTs which were analog in nature.. DVI is digital while VGA is analog. 2. VGA is for CRT monitors while DVI is best for LCD monitors. 3. Using VGA for LCD monitors leads to multiple conversions that might slightly alter the final image. 4. DVI is newer and would soon make VGA obsolete.
