SOS Origin and Meaning :-

A Pattern, Not an Acronym: SOS was chosen because the sequence of three dots (S), three dashes (O), and three dots (S) is easily and clearly transmitted and recognized in Morse code.

International Standard: The signal was first adopted by the International Radiotelegraph Convention in 1906 and became a worldwide standard for distress calls in 1908.

Mnemonic Devices: Phrases like "Save Our Souls" and "Save Our Ship" were later developed to help people remember the SOS pattern.

How it Works :

Morse Code: The SOS signal is transmitted as a continuous series of dots and dashes, without any spaces between the letters.

Universal Signal: It is used globally to signal danger and a need for immediate help in various emergency situations, including maritime, aviation, and land-based incidents.
