In a computer system, any external device must be connected to the host computer through a ().

In a computer system, any external device must pass through a (B. interface adapter) in order to connect to the host computer.

In computers, adapters are usually built into cards that fit into slots on the motherboard (there are also external ones). Adaptation information from the card is exchanged with the processor and between devices supported by the adapter.

Power adapter is a small portable electronic equipment and electronic appliances power supply conversion equipment, generally by the shell, power transformer and rectifier circuitry, according to its output type can be divided into AC output type and DC output type; according to the connection can be divided into wall-plug type and desktop type. Mobile PCs do not have batteries, power adapters are especially important for them.

Most mobile PCs have power adapters that automatically detect 100 to 240V AC (50/60Hz). Basically all mobile PCs have the power supply external, connected to the mainframe with a cable, which reduces the size and weight of the mainframe, and only a very few models have the power supply built into the mainframe. There is a nameplate on the power adapter that indicates the power, input and output voltages, and current draw, with special attention to the input voltage range, which is known as the "travel power adapter".

When MBeans are registered with the MBean server, a protocol is needed to interact with those MBeans and retrieve information for requests from the management application. This is enabled through a protocol adapter that converts management application data into standard protocol information.

Adaptation Patterns

In computer programming, an adapter pattern (sometimes called a wrapper style or package) adapts the interface of a class to what the user expects. An adaptation allows classes that would not normally work together because of incompatible interfaces to work together by wrapping the class's own interface in a pre-existing class.

The adapter pattern is primarily used when the methods defined in an interface do not meet the needs of the customer, or when the name or method interface of a method defined in an interface conflicts with the customer's needs.

Two types of patterns: - Object Adapter Pattern - In this adapter pattern, an adapter holds an instance of the class it wraps. In this case, the adapter calls the physical entity of the wrapped object. -Class Adapter Pattern - In this adapter pattern, the adapter inherits from the self-implemented class (generally multiple inheritance).

Adapters do not have data rate conversion capabilities.

In computer programming, adapters include: container adapters, iterator adapters, generic adapters, etc.
