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.

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.
Can protocol is synchronous or asynchronous?
CAN protocol is synchronous, as it relies on a fixed timing mechanism for communication between nodes. This timing mechanism establishes when messages can be transmitted and ensures they arrive at the intended recipient without delays.
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.
What is the difference between unclocked SR flip flop and clocked sr flip flop?
An unclocked SR flip-flop is asynchronous and changes output based on the inputs at any time, which can lead to timing issues and glitches. A clocked SR flip-flop is synchronous and changes output only at the rising or falling edge of a clock signal, ensuring more reliable operation and avoiding glitches.
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 Synchronous and asynchronous computer bus timing?
asynchronous bus A bus that interconnects devices of a computer system where information transfers between devices are self-timed rather than controlled by a synchronizing clock signal.
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 generator and synchronous motor?
ASYNCHRONOUS is a mode whereby events happens irregardless of control. SYNCHRONOUS are this same events but controlled by a timing and/or control
Compare synchronous and asynchronous operation of sequential circuits?
A Synchronous Sequential Circuit is a system whose behavior can be defined on the timing of their signals , where in the case of asynchronous sequential circuit depend upon the order in which its inputs signals change and can be affected at any instance of time . (reference : M. Moris Mano)
How synchronous work?
With timing, sent from end to end. Examples are synchronous data with explicit timing circuits at interfaces and plesiochronous where the timing is embedded in the main signal by line codes. Asynchronous, without timing is historical and relates to teleprinter speeds up to 300 bit/s.
Can protocol is synchronous or asynchronous?
CAN protocol is synchronous, as it relies on a fixed timing mechanism for communication between nodes. This timing mechanism establishes when messages can be transmitted and ensures they arrive at the intended recipient without delays.
What is asynchronous timing?
Asynchronous timing means that between two devices there is no deterministic timing relationship. It means the NI hardware does not actively adjust the timing of signals to align them with a specific clock edge.
Difference between synchronous bus and asynchronous bus in an input operation?
A synchronous bus operates with a clock signal that coordinates data transfer, ensuring that all components are synchronized during input operations. In contrast, an asynchronous bus does not rely on a clock signal; instead, it uses handshaking signals to manage data transfer, allowing devices to operate independently and at different speeds. This can lead to more flexible communication but may introduce complexity in timing and control. Essentially, synchronous buses provide predictability and speed, while asynchronous buses offer flexibility and adaptability.
Is counter 74ls893 Synchronous?
Yes, the 74LS893 is a synchronous binary counter. In a synchronous counter, all flip-flops are clocked simultaneously by a common clock signal, allowing for predictable timing and operation. This design enables the counter to count in a coordinated manner, reducing propagation delays associated with asynchronous counters.
What is the difference between uart and usart?
UART is universal asynchronous receiver/transmitter. It is a piece of computer hardware that translates data between parallel and serial forms. Modern ICs that have UART's that can also communicate synchronously are called USARTs (universal synchronous/asynchronous receiver/transmitter).
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.
