characteristics‚ esp. its ability to carry charge carriers at speeds dwarfing those possible in silicon that allow superfast switching in data processing They can also be chopped into transistors‚ showing the way to mass production. IBM achieved another milestone by demonstrating 100-gigahertz graphene-based transistors‚ and set a new record at 300 GHz. And if graphene keeps progressing as fast as it has in the past few years‚ it will surely attract the immense weight of investment in research and development

and “Off”. In order to represent these states‚ the binary system was created. Capitalizing on the ground works of the binary system‚ logic gates (transistors) are built to change the states of these signals. By combining logic gates‚ we are able to build complex. The computer processor is one of those units that are made up of thousands of transistors. Since processors are made of logic gates that understand binary‚ it is only natural to feed them with inputs that are in binary formats. In this
