A system of sending messages by holding the arms or two flags or poles in certain positions according to an alphabetic code. Semaphore flags are still in use today, but have evolved into square flags on short poles. The signalman holds a semaphore flag in each hand and holds his arms in a variety of specific positions to convey a message to someone else. When the system is used at sea, the flags are red and yellow, and, when on land, the flags are white and blue. Flags are not required, but do make the characters that are transmitted easier to see.

Even in these days of radio and satellite communications, the U.S. Navy uses the international alphabet flags, numeral pennants, numeral flags, and special flags and pennants for visual signaling. These signal flags are used to communicate while maintaining radio silence. Navy Signalmen transmit messages by hoisting a flag or a series of flags on a halyard. Each side of the ship has halyards and a "flag bag", containing a full set of signal flags. Signals unique to the Navy are used when communicating with other U.S. Navy or allied forces. When communicating with all other vessels, the International Code of Signals is used. The code/answer pennant precedes all signals in international code.

What is Morse Code?
What is Morse Code?
Morse code is an alphabet or code in which letters are represented by combinations of long and short signals of light or sound.
What was the Importance of Morse Code?
What was the Importance of Morse Code?
Before the invention of Morse Code and the telegraph, messages were still handwritten and carried by horseback. Morse Code changed the way we communicated. In the time of its invention, it was the fastest long distance form of communication.
Morse Code allowed for ships at sea to communicate over long distances using large lights. Morse Code was especially pivotal during the second World War because it greatly improved the speed of communication. Naval war ships were able to communicate with their bases and provide critical information to each other. War planes also used Morse Code to detail locations for enemy ships, bases, and troops and relay them back to headquarters. From Owlocation, https://owlcation.com/humanities/morse_code
