What is the difference between synchronous and asynchronous I O which one is better suited for use in real time applications?
In Synchronous transmission, There is no gap present between data. It is more efficient and more reliable than asynchronous transmission to transfer the large amount of data. Asynchronous Transmission: In Asynchronous Transmission, data is sent in form of byte or character.
What is the difference between synchronous I O and asynchronous I o discuss the implications of two types of I O in real time applications?
In synchronous file I/O, a thread starts an I/O operation and immediately enters a wait state until the I/O request has completed. A thread performing asynchronous file I/O sends an I/O request to the kernel by calling an appropriate function.
What is the difference between synchronous and asynchronous IO?
Synchronous I/O mean that some flow of execution (such as a process or thread) is waiting for the operation to complete. Asynchronous I/O means that nothing is waiting for the operation to complete and the completion of the operation itself causes something to happen.
What is asynchronous I O and how would it be used in a network application?
Asynchronous I/O is most commonly used in realtime applications requiring high-speed or high-volume data collection and/or low-priority journaling functions. Compute-intensive processes can use asynchronous I/O instead of blocking. For example, an application may collect intermittent data from multiple channels.
What is asynchronous polling?
Asynchronous polling pertains to the input of responses a poll or survey at one’s own pace. It is still an interactive audience response system.
CAN protocol is asynchronous?
The Controller Area Network (CAN) is an asynchronous serial CSMA/CD+AMP communication protocol for microcontrollers networks, supporting distributed real-time control (bit rate up to 1Mbps) with a very high level of security.
Why is synchronous counter faster?
While in Synchronous Counter, all flip flops are triggered with same clock simultaneously and Synchronous Counter is faster than asynchronous counter in operation. In synchronous counter, all flip flops are triggered with same clock simultaneously.
