AnswerSynchronous communication is direct communication where the communicators are time synchronized. This means that all parties involved in the communication are present at the same time. This includes, but is not limited to, a telephone conversation (not texting), a company board meeting, a chat room event and instant messaging. Asynchronous communication does not require that all parties involved in the communication to be present at the same time. Some examples are e-mail messages, discussion boards, blogging, and text messaging over cell phones. In distance (specifically online) education asynchronous communication is the major (sometimes the only) method of communication. Usually, we use different discussion boards in each class with each having its own purpose.



Although all parties maybe present at the same time, they don't necessarily communicate in a synchronized fashion. Telephone conversations, board room converstions, and chat sessions are asynchronous in nature due to the fact that each participator can interrupt at any given moment which makes them inherently asynchronous.

Why is a start bit used in asynchronous communication?

Answer . \nAsynchronous (serial) communication means that all the necessary decoding information is carried in the data stream, with no need for any external timing reference. The start bit is needed to tell the receiver that the next so-many bits are data. Likewise, the stop bit tells the receiv ( Full Answer )

What is the difference between synchronous and asynchronous?

Sychronous transmission does not add start & stop bits at the beginning and end each byte transmitted for sending data segments while Asychronous transmission uses start & stop bits which are added at the start & end of data blocks. Sychronous transmission provides 64 or 128 Kbps speed but asy ( Full Answer )

What is asynchronous communication?

An Asynchronous Communication is where there is 'variable bit rates' at the send and receive ends, in other words the send and receive clock generators are not synchronized as in a Synchronous Communication..

What is dfference between synchronization and asynchronization?

I believe you mean synchronous and asynchronous... as in calling a function synchronously or asynchronously.. When you call a function synchronously, the program waits for the function to finish before continuing on.... i = i + 1. DoSomething(). j = j + 1

What are the differences between synchronous and asynchronous?

Synchronous AC motors run at a speed fixed by the input linefrequency. Typically 60 Hz in the USA. Run a clock with the syncmotor from the USA in England and it runs slow because they use50Hz.

Synchronous and asynchronous transmission?

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 is the difference between synchronous and asynchronous cryptography?

I believe you are asking about "symmetric vs asymmetric" cryptography.. In a symmetric cryptographic cipher both parties must use the same key for encryption and decryption.

in synchronous communication data will be transmitted with clock and in asynchronous only start and stop bit is required for transmission of data but speed of the data transmission in synchronous is very high data rate and in asynchronous speed is slow due to the start and stop bit .

What is the difference between asynchronous dram and synchronous dram?

Conventional DRAM, of the type that has been used in PCs since the original IBM PC days, is said to be asynchronous . This refers to the fact that the memory is not synchronized to the system clock.

Why is Synchronization a problem in data communication?

synchronization between the multiplexer and demultiplexer is a major issue in data transmission. if the multiplexer and demultiplexer are out of synchronization a bit belonging to one channel may be received by the wrong channel. for dis reason , one or more synchronization bits are usually added to ( Full Answer )

Differences between asynchronous connections synchronous and isochronous connections?

What is the difference between synchronous and asynchronous data transfer?

Synchronous= syn+ chrono = togetherness in time. So, the two ormore communication system agree to be together in time to thechange in signals or data.That means they should share the sameclock speed.

Difference between synchronous and asynchronous counters?

Synchronous counters are the ones in which each flip flop is driven by the same clock. whereas in asynchronous counters, each flip flop is driven by different clock. output of the preceding flip flop is used as as a clock for the next flip flop. Synchronous counters can do any sort of counting like ( Full Answer )

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 synchronous and asynchronous time division multiplexing?

1) IN syncronous TDM , the multiplexer allocates exactly the same slot to each device at all times , whether or not a device has something to transmit in contrast, in asyn TDM if thedevice have nothing to transmit then its time slot is alloted to another device. 2) synch TDM requires a common clock ( Full Answer )

What is difference between synchronization and inter thread communication?

Synchronization is the process by which, access to the objects by threads are controlled and at at time only one thread can access an object. This is done to ensure that there are no dirty read/write operations. If multiple threads access the same data simultaneously, we may end up with inconsistent ( Full Answer )

Put asynchronous communication in a sentence?

Asynchronous just means 'not synchronised'. So a telephone conversation is asynchronous communication because each party to the conversation can talk when they want, they are not synchronised to (for example) only talk for 10 seconds and then listen for 10 seconds! 'Synchronous communication' ( Full Answer )

What is the difference between asynchronous and synchronous machines?

In digital transmission. Asyncronous has a start and stop bit per byte. The Byte is actually 10bits long. In sychronous there is only a sync bit and that's it. Asyncronous is not as good ad syncrounous because it takes alot of bandwidth and about 20% of the transmission is just start and stop bits.
