What is Morse code?
Morse code is a communication system using dots (short signals) and dashes (long signals) to represent letters and numbers. Developed by Samuel Morse in the 1830s, it was the first practical telecommunications system.
What does SOS mean in Morse code?
SOS is ··· −−− ··· (three dots, three dashes, three dots). It was chosen as the distress signal because it is simple to transmit and unmistakeable. It does not stand for any particular phrase.
Is Morse code still used today?
Yes. Amateur (ham) radio operators use Morse code globally. It is also used in aviation navigation beacons, military communications and accessibility tools for people with physical disabilities.
How fast is Morse code transmitted?
Speed is measured in WPM (words per minute) based on the word 'PARIS' as a standard. Beginners typically learn at 5 WPM; experienced operators communicate at 20–30+ WPM.
