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.
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 synchronous buses and non synchronous buses?
Synchronous buses use a clock signal to synchronize data transfers between components, ensuring that data is transferred at a predictable rate. Non-synchronous buses transfer data without a clock signal and rely on other mechanisms to coordinate data transmission. Synchronous buses are generally faster and more efficient but can be more complex to design and implement compared to non-synchronous buses.
What are the differences between synchronous and asynchronous?
Synchronous AC motors run at a speed fixed by the input line frequency. Typically 60 Hz in the USA. Run a clock with the sync motor from the USA in England and it runs slow because they use 50Hz. Asynchronous motors run at whatever free-run speed they feel like, and slow under load. A DC wound hand-drill is such a motor, runs pretty fast till you start drilling, then it slows down. A synchronous motor will develop maximum power at its' designed speed, try to slow it down and it puts out more torque. Slow it down by overload, it doesn't create more power, it just creates more heat. An Async motor creates highest torque at stall speed, least torque as it approaches maximum speed.

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.
Why Is HTML synchronous?
HTML is synchronous because the base protocol, HTTP (Hypertext Transfer Protocol) does not maintain a connection with the server. This was because, at the time, no one could imagine wanting a protocol that kept state. Give that the protocol doesn't track the user, there'd be no way for HTML to by asynchronous.
Is VoIP a synchronous or asynchronous form of communication?
synchronous
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.
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
What is usart?
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 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.
What are examples of synchronous protocol?
SONET
Does Synchronous memory retrieves data faster than asynchronous memory?
yes
