Want this question answered?
it is the difference between the synchronous and asynchronous speed of a induction motor
i/o data transfer speed of time
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.
synchronous means it is based on a clock...it performs operations based on every clock tick....asynchronous operations execute irregardless of the clock signal
internal interrupt is synchronous with the program while external interrupts are asynchronous.
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)
ASYNCHRONOUS is a mode whereby events happens irregardless of control. SYNCHRONOUS are this same events but controlled by a timing and/or control
Synchronous circuits operate under the influence of s clock pulse while asynchronous circuits operate without the influence of a clock pulse
The 8251 is a USART (Universal Synchronous Asynchronous Receiver Transmitter). It does not have a minimum and maximum mode.
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.
1)Synchronous motors are those that run only at Synchronous speed i.e. constant speed. But Motor can run in various speeds. 2)Synchronous motors runs at same speed of magnetic filed. but if one consider case of induction motor the rotor rotates at different speed than revolving magnetic field. there is slip between field and rotor.
The main difference between Synchronous random access memory, SDRAM and Dynamic Random Access Memory, DRAM is that SDRAM is synchronous while DRAM is asynchronous. As such, SDRAM is efficient in retrieving and storing data than DRAM.
