What Is a Display Adapter?

An adapter is an interface converter, which can be an independent hardware interface device, allowing the hardware or electronic interface to be connected with other hardware or electronic interfaces, or it can be an information interface. For example: power adapter, tripod base conversion parts, USB and serial port conversion equipment, etc.

In a computer, an adapter is usually built into a card (also external) that can be inserted into a slot on the motherboard, and the adapter's adapter information is exchanged with the processor and the device supported by the adapter.

The power adapter is for small portable electronic equipment and electronic appliances

Protocol adapters supported by the Multiprotocol Agent include: SNMP, TL1, RMI, CORBA, HTTP, and HTML adapters.

In the actual development process, we often encounter such things. We have formulated a base class based on the initial requirements. Only during the development process did we learn that detailed requirements or requirements have changed. The interface in the development work has already been defined and has been put into coding on a large scale. At this time, if the definition of the interface is changed, it will cause a lot of repetitive modification work on the coding, and then it may cause semantic errors or logical errors caused by incomplete modification. Semantic errors can still be found during the compilation phase, and once a logical error occurs, the consequences will be very serious, even enough to cause the system to crash. Needed at this time

In computer programming, the adapter pattern (sometimes called a wrapper style or wrapper) adapts the interface of a class to what users expect. An adaptation allows classes that cannot usually work together because of incompatible interfaces to work together by wrapping the class's own interface in an existing class.

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

Two types of patterns: 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 pattern-In this adapter pattern, adapters inherit from implemented classes (generally multiple inheritance).

Adapter does not have

How to use the adapter mode:

Use a class to inherit both the interface and the known class, and use the methods and properties defined in the known class to implement the definition of the interface (mainly using the method of overloading interface methods). Use this class as the base class for other business classes, that is, this class adapts interfaces and known classes. If the known class changes, you only need to modify the class adapter to meet the implementation of the interface.

In April 2016, Microsoft released a new generation of wireless display adapter in China: Microsoft Wireless Display Adapter V2. According to Microsoft, on the basis of fully retaining the lightweight and easy-to-use advantages of the previous generation of products, the adapter has been further optimized and improved in terms of improving device compatibility, reducing signal delay, and compact and portable design. Even in a non-Internet environment, it can still be used smoothly, and it is an essential companion for modern meetings and life entertainment. ^[2]

A host adapter ( host adapter ) or host bus adapter ( HBA ) is a computer hardware that uses a computer as the host system and connects to other network or storage devices. This term refers primarily to devices that connect SCSI, Fibre Channel, or eSATA devices. However, devices connected to IDE, Ethernet, FireWire, USB, or other systems may also be called host adapters.
