computing, adapter is a hardware device or software component, that converts transmitted data from one presentation form to another. The data presentation can be, for example, a message sent between objects in an application, or a packet sent through a network.
In modern personal computer, almost every
peripheral device, uses an adapter to communicate with system bus, for example:
Display adapter, used to transmit signal to monitor.
Universal Serial Bus(USB) adapters for printers, keyboards and mice, among others.
Network adapterrequired to attach to any network.
Host bus adapter, to connect hard disks or other storage.A concept of adapter should not be confused with an expansion card. Although every expansion card typically implements some kind of adapter, many other adapters in a modern PC are built into the motherboarditself.
software componentadapter is a type of software that is logically located between two software components and reconciles the differences between them.
computer programming, the adapter design pattern(often referred to as the wrapper pattern or simply a wrapper) is a design pattern for adapting one interface of a class into another interface that a client expects.
Resource adapters are used to retrieve and route data.fact|date=March 2008 They provide access todatabases, files, messaging systems, enterprise applications and other datasources and targets.Each adapter includes a set of adapter commands that can be used to customizeits operation. Adapter commands specify different queues and queuemanagers, specific messages by message ID, specific sets of messages with thesame message ID, message descriptors in the data, and more.
Resource adapters answer the question "Where should have the data come from?" and"Where should the data go?".
The resource adapters provided with many integration products enable datatransformation and adapter-specific behavior recognition on different systems anddata structures.
