Use Mild Speed to Find Your Server

Resources to Find Your Server

The fantastic information is you do not require a super correct take a look at, as a substitute, a comparatively correct answer is readily accessible. All you require is a tiny knowledge of the velocity of gentle and optical fiber! Vital parts of data:

one. Mild travels at around 186,000 miles for every second or 186 miles for every millisecond in a vacuum.
two. Fiber has a refractive index of all-around one.forty six.
3. The modern “Internet” is fiber when dealing with extended distances.

In scenario you have not discovered, these are not precise calculations.

The following move in your discovering method is to comprehend a “ping” take a look at. You probably have the “ping” tool on your computer previously. “Ping” is a straightforward plan utilized to test community connectivity and effectiveness.
