Microseconds (us)
Nanosecond (ns)
Picosecond (ps) Thousand operations per second (1 / 1000)
Million operations per second (1/1.000.000)
Billion operations per second (1/1.000.000.000)
Trillion operations per second (1/1.000.000.000.000)
Unit time computer speed

Other capabilities of the computer is accurate, if man tired of the tendency to make bigger mistakes. The computer will make mistakes when:
 damaged components
 The data in the entry wrong (The term GIGO: Garbage in gabage out, gold in gold out)
