Is VoIP a synchronous or asynchronous form of communication?

synchronous


Why the synchronous modems are more costly than the asynchronous modems?

Because they contain clock recovery circuits


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.


What are the differences between UART and USB?

Different data rate speed (for rs232 is lower), usb is more flexible and takes less energy. Different instructions and commands. If you are a programmer then it's easier for to work with usb then with rs232.


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


Difference between synchronous and asynchronous flip flops?

synchronous means it is based on a clock...it performs operations based on every clock tick....asynchronous operations execute irregardless of the clock signal


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 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.
