penn state scientists have built the first silicon-free computer, powered by a 2d material just one atom thick. the achievement paves the way for an era of ultra-compact and
optical connections will allow for faster, thicker processors (containing more transistors).
the 3.5mm jack is a small connector, but contains a long history and a tremendous support for the development of technology.
the way the computer industry has become modern is not simple today. it includes many milestones marking many different stages of development.
