A controller electric current flows in the computer. Its shape is a bit different. The positive and negative parts of this wave are square.
Hence the name ‘Square Wave’. The speed of computer operation depends on this controller electromagnet.
It takes some movement in this wave to process every instruction of the computer. But the vibrations of the controller of a modern computer are extraordinary.
EQUATION OF SPEED OF COMPUTER
The regular IBM personal computer receives 80 lakh waves per second. Waves in large computers cost more than this.
Divide this number by the number of vibrations that the movement gets yesterday. From this formula, the movement of electricity in IBM’s personal computer can be easily removed.
Movement period = (1/Vibration Number) seconds
= (1/8000000) seconds
= [(1/8)*10^-6] seconds
= (0.125*10^-6) seconds
= (125*10^-9) seconds
You can’t imagine such a short time. It may take longer to blink your eyelids.
SECOND METRICS TABLE
Of course, in computer language, the fraction of milliseconds, micro-nano, pica, respectively, is more important than the second.
Their table can be written as follows.
|One millisecond||One-thousandth of a second||10^-3 second|
|One micro second||One-millionth of a second||10^-6 second|
|One nanosecond||One-billionth of a second||10^-9 second|
|One picosecond||One-trillionth second||10^-12 second|
This means that the movement of the controller current in IBM personal computer is 125 nanoseconds or 0.125 microseconds.
Suppose, it takes 4 movements to process an instruction, which means that the execution of that instruction is completed in 4 x 125 nanoseconds or 0.5 microseconds.
EXAMPLE OF SPEED OF COMPUTER
Let’s try a little different math to get an idea of the very short time in a computer, the ratio of one second to one nanosecond is the same as the ratio of 31 years 8 months 15 days to one second.
Or the ratio of one second to 31710 years is greater than one second, one picosecond. Check out another fun example! If we traveled at a speed of 100 centimeters per nanosecond, we would be able to complete about 25 Earth orbits in just one second.
This means that your travel speed will be around 10 lakh kilometers per second. At this speed, we can go to the moon in 0.768 seconds and come back.
Here is a glimpse of the subtle parts of a second!
