As we all heard of Adapter many times, it can be a TV adapter, Telephone Adapter, Adapter for speakers etc., Adapters are used very commonly in many of the Electronic devices. They play a key role in the Electronic Consumer Industry.
ADAPTER: An adapter is a physical device that allows one hardware or electronic interface to be adapted (accommodated without loss of function) to another hardware or electronic interface. In a computer, an adapter is often built into a card that can be inserted into a slot on the computer’s motherboard. The card adapts information that is exchanged between the computer’s microprocessor and the devices that the card supports.
So, an adapter acts as an interface to allow communication between two devices with minimal loss. Let us see few Devices in which adapters are used and what functionality do they provide.
Analog Telephony Adapter
An analog telephony adapter, or analog telephone adapter, (ATA) is a device used to connect one or more standard analog telephones to a digital telephone system (such as Voice over IP).
Analog Telephone Adaptor is a handset-to-Ethernet adaptor that turns traditional telephone devices into IP devices. Customers can take advantage of the many new and exciting IP telephony applications by connecting their analog devices to ATAs.
So using ATA even an analog phone can be interfaced to have IP telephony applications.
The AC adapter, AC/DC adapter or AC/DC converter is a type of external power supply, often enclosed in a case similar to an AC plug. Other names include plug pack, plug-in adapter, adapter block, domestic mains adapter, line power adapter, or power adapter. AC adapters are used with electrical devices that require power but do not contain internal components to derive the required voltage and power from mains power. The internal circuitry of an external power supply is very similar to the design that would be used for a built-in or internal supply.
A digital television adapter (DTA), or digital-to-analog converter [set-top box], or commonly known as a converter box, it is a television tunerthat receives a digital television (DTV) transmission, and converts the digital signal into an analog signal that can be received and displayed on ananalog television set.
Adapter – as the name states it is use for both the communicating devices to Adapt to each other.
