In 2009 Kao was awarded the Nobel Prize in Physics for his function. Plastic fibers, generally made of polymethylmethacrylate, polystyrene, or polycarbonate, are much less expensive to generate plus more versatile than glass fibers, but their larger attenuation of light restricts their use to A great deal shorter back links inside buildings or vehicles.
In the event the switch has multiple switching module, the switching module also has some kind of "backplane" connector accustomed to link the switching modules.
Huge mainframe desktops are a costly financial commitment, and it makes a lot more feeling to incorporate processors at strategic details while in the method. This not only increases functionality but additionally saves cash.
Encyclopaedia Britannica's editors oversee subject areas in which they have extensive awareness, irrespective of whether from decades of experience gained by working on that content or via study for a complicated degree.
