What is the ON key on a calculator?
2 Answers
The ON key on a calculator is the power button. Below is a detailed introduction to calculators: 1. A calculator is an electronic machine invented by modern people for performing numerical operations. 2. Modern electronic calculators are handheld electronic devices capable of mathematical operations, equipped with integrated circuit chips, but their structure is much simpler than that of computers. They are considered the first generation of electronic computers (computers) with relatively weaker functions, but they are more convenient and affordable. Widely used in commercial transactions, calculators are essential office supplies. In addition to displaying calculation results, they often include overflow indicators and error indicators. 3. Calculator power sources use AC adapters or batteries, which can be recharged using AC adapters or solar converters. To save energy, calculators use large-scale integrated circuits manufactured with CMOS technology.
Oh, that so-called 'on button' is actually the power button. I always call it the startup button because it's responsible for turning on the computer screen and booting up the entire system. When I use a desktop computer daily, the button is usually located on the front panel of the main case—just press it, and you can hear the fan whirring while the indicator light turns on. On laptops now, it's moved to the top or side of the keyboard area, and a light touch is enough to start the device. However, I’ve made mistakes before by accidentally pressing it, causing the computer to shut down suddenly and lose unsaved files, so now I remind myself to press it lightly and briefly to avoid issues. The design of the power button is quite smart—on some computers, a short press puts it to sleep or wakes it up, while a long press forces a shutdown, terminating all operations. If the button is broken or has poor contact, the computer may fail to start, requiring a check of the connection cables. Overall, without this little button, the computer would be as useless as a brick. It’s best not to tamper with it carelessly to ensure smooth startup.
