1 second = 1,000 milliseconds
A human blink takes about 150ms. Your computer can run millions of instructions in that time!
1 second = 1,000,000 microseconds
Sound travels just 0.3mm in a microsecond. Your CPU executes thousands of instructions in this time!
1 second = 1,000,000,000 nanoseconds
Light itself only travels 30cm in a nanosecond. This is where a single CPU cycle happens!
Computers are unbelievably fast
In the time you say "one", a computer completes 3 billion operations
Before you can even react, a computer has done 600 million things
Learn to write code and command billions of operations!
