Is the power adapter a switching power supply? What is the difference between the two

The Adapter is the Chinese translation of the English adapter / adapter. Adapter is an interface Converter, which can be an independent hardware interface device, allowing hardware or electronic interface to connect with other hardware or electronic interface, or information interface. For example: Power Adapter, tripod base adapter, USB and serial port adapter.

In a computer, the adapter is usually built into a card that can be inserted into a slot on the motherboard (or external)... The adapter information in the card exchanges with the devices supported by the processor and the adapter.

Power adapter is a small portable electronic equipment and the Power Supply conversion equipment of electronic appliances. It is generally composed of shell, power transformer and rectifier circuit. According to its output type, it can be divided into AC output type and DC output type; according to the connection mode, it can be divided into plug-in type and desktop type. Because mobile PC has no battery, power adapter is very important to it.

Most mobile PC power adapters can automatically detect 100-240V AC (50 / 60Hz). Basically, all Mobile PCs have external power supply, which is connected to the host with one line, so that the volume and weight of the host can be reduced. Only a few models have internal power supply. There is a nameplate on the power adapter, which indicates the power, input and output voltage, current and other indicators. Pay special attention to the range of input voltage, which is the so-called "travel power adapter".

When MBeans are registered with the MBean server, they need protocols to interact with these MBeans and retrieve information for requests made from the management application. This is enabled through the protocol adapter, which can convert management application data into standard protocol information.

The protocol adapters supported by multi protocol agent include SNMP, TL1, RMI, CORBA, HTTP and HTML adapters.

In computer programming, the adapter pattern (sometimes referred to as a wrapper or wrapper) adapts the interface of a class to what the user expects. An adaptation allows classes that cannot work together, usually because their interfaces are not compatible, to work together by wrapping their own interfaces in an existing class.

The adapter pattern is mainly used when the methods defined in the interface cannot meet the customer's requirements, or when the name of the methods defined in the interface or the method interface conflicts with the customer's requirements.
