Nanosecond (ns or nsec)

Nanosecond (ns or nsec) is a unit of time equal to one billionth of a second (10-9 seconds). It is also equal to 1000 picoseconds or 1/1000 microsecond. Is nano second billionth? No, a nanosecond is not a billionth. A nanosecond is one billionth of a second, so a nanosecond is a fraction of a … Read more


A nanotransistor is a transistor in which at least one dimension of the active region is on the order of one nanometer (10−9 meters). Nanotransistors are a key building block of nanoelectronics, which is an emerging technology that promises to revolutionize electronic devices and circuits. Traditional transistors are made by depositing layers of different materials … Read more
