Adapter is an interface converter that allows hardware or electronic interfaces to be connected to other hardware or electronic interfaces. In a computer, the adapter is usually built into a card that can be inserted into a slot on the motherboard (there are also external ones)... The adapter information in the card is exchanged with the processor and the devices supported by the adapter.
  The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of a shell, a power transformer and a rectifier circuit. According to its output type, it can be divided into AC output type and DC output type; according to the connection method, it can be divided into wall plug And desktop. Since mobile PCs do not have batteries, power adapters are particularly important for them.
  The power adapter of most mobile PCs can automatically detect 100~240V alternating current (50/60Hz). Basically all mobile PCs have an external power supply and connect to the host with a cable, which can reduce the size and weight of the host. Only a few models have the power built in the host.
  There is a nameplate on the power adapter, which indicates the power, input and output voltage and current and other indicators. Pay special attention to the range of the input voltage. This is the so-called "travel power adapter".
  In computer programming, the adapter pattern (sometimes called packaging style or packaging) adapts the interface of a class to what the user expects. An adaptation allows classes that normally cannot work together because of interface incompatibility to work together, by wrapping the class's own interface in an existing class.
  There are two types of adapter modes:
  · Object adapter pattern-In this adapter pattern, the adapter holds an instance of the class it wraps. In this case, the adapter calls the physical entity of the wrapped object.
  ·Class adapter mode-In this adapter mode, the adapter inherits from the implemented class (generally multiple inheritance).
