What is the AC key on a computer called?
3 Answers
The AC key on a calculator is called the Clear key, which stands for All-Clean in English, meaning to clear everything. Here is some information about calculators: Correction key: The "CE key" on a calculator represents the Partial Clear key, also known as the Correction key. Its function is to clear the currently entered number, rather than clearing previously entered numbers. For example, if you just entered an incorrect number, pressing this key immediately will clear it, allowing you to input the correct number and continue the original operation. Clear key: The "MC key" on a calculator represents the Memory Clear key, also known as the Memory-style Clear key. Its function is to clear stored data, erase the memory contents, and only clear the numbers in the memory. It clears the data in the memory but does not clear the numbers displayed on the screen.
I've noticed many friends asking what the AC button in a car is—it's actually the air conditioning switch button. AC stands for Air Conditioning. Pressing this button activates the car's air conditioning, blowing cool air to make driving in hot weather more comfortable. The button's location varies by car model—some are on the dashboard, while others are on the center console. From my driving experience, pressing the AC button immediately after getting in the car during summer, combined with adjusting the fan and temperature knobs, can cool the interior quickly. It's also important not to leave it on for too long to avoid wasting fuel. Regularly cleaning the AC filter is crucial, as a dirty filter can reduce airflow efficiency. If the AC light doesn't turn on, checking the fuse is necessary—these small details significantly impact the driving experience.
In a car, the AC button is the start button for the air conditioning. Once pressed, the compressor begins to work and cool the air. I often experience significant temperature changes while driving, and pressing the AC automatically adjusts the airflow and temperature, which is very convenient. For models with automatic air conditioning, pressing the AUTO button enables the system to intelligently control the settings—you only need to adjust the temperature knob. Remember to use the internal and external circulation wisely while driving. Internal circulation cools the car quickly but shouldn’t be used for too long, while external circulation keeps the air fresh. If the air conditioning stops working, it might be an electrical issue—don’t attempt to fix it yourself; seek a professional technician immediately.
