Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary electrical function?To provide a physical interface for transmitting analog electrical signals, primarily audio
2. What is the key configurations?TS (Tip-Sleeve) for mono/unbalanced signals and TRS (Tip-Ring-Sleeve) for stereo/balanced signals
3. Why do phone connectors still matter even with Bluetooth and USB?Phone connectors are still important because they can send raw audio signals directly without extra digital conversions. This keeps the sound clear and fast, which is especially useful for musicians and professional audio gear. They are also cheap and simple to use.
4. How does a phone connector work to send sound?A phone connector works by touching metal parts inside the plug and jack. The tip, ring, and sleeve make a direct electrical path so the sound’s voltage can move straight from one device to the next. The signal travels without being changed.

Analog Signal: An electrical signal that is a continuous representation of a physical quantity, such as sound waves.
Tip-Ring-Sleeve (TRS): A common phone connector configuration with three conductive sections for stereo audio or balanced signals.
Latency: The delay between the input of a signal and its output, which is typically very low for analog phone connectors.
