. Ask yourself why we can't use the plug to get to the UK. Why does the monitor have DVI,VGA,HDMI,DP so many interfaces at the same time? Many of the norms and standards were initially formulated without realizing that this would be a universal norm later on, or that the interests of the Organization itself would be fundamentally different from existing standards. As a result, there are so many standards that have the same effect but are not compatible with each other.Said so much we look at a p
