Abbreviated as ns or nsec, a nanosecond is a unit of time representing .000000001 (10-9) or 1 billionth of a second. Computer memory speed is often represented in nanoseconds, for example, 60ns, 40ns, and 10ns are all different speeds of time it takes for the computer to access the memory. The lower this number is, the faster the computer can access its memory. In the three examples above, 10ns would be the fastest memory.
