Adapters are devices and devices that are completely different from each other in design. One thing unites them: they coordinate with each other two objects of one kind or another, which are not directly compatible with each other.
Older people will remember that adapters are sometimes called pickups used in turntables. In those years when gramophones and gramophones were widespread, many of their owners wanted to listen to records through amplifiers without changing the entire apparatus. To match the existing gramophone or gramophone with an amplifier, an adapter was installed on it. Later, when players began to be equipped with piezoelectric or electromagnetic heads initially, they almost ceased to call pickups adapters. For the same reason, pickups for guitars and other musical instruments, especially those in the design of which they were not originally provided for, are called adapters today. Tools equipped with them are called adapters. Power supplies made in housings that look like large mains plugs are also called adapters. They match low-voltage, but sometimes high-current inputs of loads with high voltage of the lighting network, consuming insignificant current from it. Anyone who knows that power is equal to the product of current and voltage will understand that this does not contradict the law of conservation of energy. Also, adapters are called adapters of any kind. Some of them are designed to coordinate electrical connectors of various designs with each other, while others are used as part of hydraulic, pneumatic, mechanical and other systems. Sometimes even fasteners bear this name. And what about the video card installed in your computer? You've probably heard it is sometimes called a video adapter. And this is correct, because you cannot directly connect the monitor to the motherboard - only through the video adapter. The only exceptions are boards with built-in video subsystems. True, modern video cards do not quite fit this definition, since they are separate computing systems, sometimes competing in performance with the computers in which they are installed. The telephone adapter is an electromagnetic device that acts similarly to the adapter for a musical instrument already discussed above. It allows you to match the speaker located in the handset of the telephone set with a voice recorder or hearing aid. If an old-style device is used, the telephone adapter can pick up the alternating magnetic field not of the sound emitter, but of the transformer of the talk unit.
