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.
Synchronous
Bits 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.
Asynchronous
Bits 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.

Is VoIP a synchronous or asynchronous form of communication?
synchronous
Is rs232 synchronous or asynchronous?
It can be either.
Why the synchronous modems are more costly than the asynchronous modems?
Because they contain clock recovery circuits
Differences between synchronous and asynchronous timing?
Synchronous timing refers to events that occur simultaneously or in a set order, while asynchronous timing refers to events that occur at different times or independently. In computing, synchronous timing means actions are performed in a fixed order and generally halt until completion, while asynchronous timing allows tasks to be executed in parallel without waiting for each other to finish.
What is the difference between synchronous IO and asynchronous IO?
If a process requests that the O/S write data to disk, and has to wait for it to be written before continuing, then that is Synchronous. If the process does not have to wait for the write to be completed, that is Asynchronous. Synchronous is real-time.
Differecne between synchronous circuit and a asynchronous circuit?
Synchronous circuits operate under the influence of s clock pulse while asynchronous circuits operate without the influence of a clock pulse
What the different between synchronous and asynchronous?
In asynchronous transmission , the receiver and the transmitter each use their own clock signals so its not possible to know when a word starts and stops. while in synchronous , the receiver and the transmission have common clock signals.
Difference between synchronous and asynchronous flip flops?
Synchronous flip-flops change outputs synchronously to a clock signal, while asynchronous flip-flops can change outputs regardless of the clock signal. Asynchronous flip-flops are not as commonly used due to potential timing hazards, while synchronous flip-flops are widely used in digital circuits to ensure reliable operation.
Difference between synchronous bus and asynchronous bus?
1. Syncrhonous bus includes clock in control lines whereas asynchronous bus is not clocked. 2. the devices which need to be connected by synchronous bus should be at same speed whereas an asynchronous bus may connect many devices with varying speeds. 3. A fixed protocol is defined to communicate using synchronous bus which is relative to the clock. An asynchronous bus uses handshaking protocol.
What is a slip in electricity?
it is the difference between the synchronous and asynchronous speed of a induction motor
Does Synchronous memory retrieves data faster than asynchronous memory?
yes
What is the difference between synchronous and asynchronous interrupts?
i/o data transfer speed of time
