Which term refers to the system of dots and dashes used to represent letters in writing and communication?

• A. Morse Code
• B. Alphabet
• C. Cipher
• D. Signaling

Answer: (A)

This question tests your ability to identify a coding system that uses short and long signals to stand for letters, enabling messages to be written and sent over distances. That system is Morse code. In Morse code, each letter is a unique sequence of dots (short signals) and dashes (long signals), designed for efficient transmission via telegraph, light, or sound. The other terms don’t fit as precisely. The alphabet is just the group of letters we use to write words, not a signaling method. A cipher is a way to hide or disguise meaning, often by substituting symbols, whereas Morse code’s purpose is to represent letters for clear transmission. Signaling is simply the act of sending a message, but it doesn’t specify the particular dot-and-dash system used to encode letters.
