Synchronous= syn+ chrono = togetherness in time. So, the two or more communication system agree to be together in time to the change in signals or data.That means they should share the same clock speed.
In asynchronous systems, the clock information is contained in the data block itself in the form of start and stop bits and hence the receiving system can adjust itself to that speed,any speed. Async systems are serial in nature and the former can be either serial or are mostly parallel.

How does Asynchronous Transfer Mode ATM transmit data?
As fixed-size cells via a fixed channel between two points
What is the purpose of uart?
UART Universal Asynchronous Receiver-Transmitter
What is new application enabled by Asynchronous Transfer Mode?
ATM is a fusion between fast switching and synchronous multiplexing technique.
What is usart protocol?
A USART protocol is computer hardware/software that converts parallel data signals to serial data signals. USART is an abbreviation for Universal Synchronous/Asynchronous Receiver/Transmitter.
What is the difference between synchronous and asynchronous interrupts?
i/o data transfer speed of time
What kind of communications does asynchronous transfer mode support?
Asynchronous transfer mode is a telecommunications concept that supports a complete range of traffic (voice, video and data). It was designed to unify telecommunications and computer networks.

Differences between asynchronous connections synchronous and isochronous connections?
These are all methods used to transfer streams of data. Waveform diagrams can be used to illustrate these different transmission modes. A waveform diagram shows how the signal might appear on an oscilloscope screen, which produces a diagram with voltage on the vertical axis and time on the horizontal axis.SynchronousBits in a synchronous data stream must be transferred in sync with a clock signal. The control signals for the data are derived from a clock signal. Synchronous data transfer systems usually have an error detection mechanism. If an error is detected the data can be resent.AsynchronousBits in an asynchronous data stream can be transferred at random intervals and the data rate of the stream is not required to be constant. Asynchronous systems use a start bit to signal the beginning of a data transmission. A stop bit is used to signal the end of a data transmission. Asynchronous data transfer systems usually have an error detection mechanism. If an error is detected the data can be resent.Isochronous (pronounced "eye-sock-ron-us")An isochronous data transfer system combines the features of an asynchronous and synchronous data transfer system. An isochronous data transfer system sends blocks of data asynchronously, in other words the data stream can be transferred at random intervals.Each transmission begins with a start packet. Once the start packet is transmitted, the data must be delivered with a guaranteed bandwidth. Isochronous data transfer is commonly used for where data must be delivered within certain time constraints, like streaming video.Isochronous systems do not have an error detection mechanism (acknowledgment of receipt of packet) because if an error were detected, time constraints would make it impossible to resend the data.
Identify the key features of Asynchronous Transfer Mode?
Transports data, video, and voice at the same time using high-speed cell-switching technology. Has a popular high speed of 622.08 Mbps that is frequently used over fiber-optic cabling.
What is asynchronus in data communication?
Asynchronous Transfer Mode (ATM) is a standard switching technique designed to unify telecommunication and computer networks. It uses asynchronous time-division multiplexing, and it encodes data into small, fixed-sized cells. This differs from approaches such as the Internet Protocol or Ethernet that use variable sized packets or frames.
What are the three types of data?
Asynchronous, Dual, and Batch. -I believe.
