Difference between synchronous & asynchronous communication...

Answer / mohammed shareef tc

In synchronous communication phase difference will be
identical each time. The clock of master controls both
master and slave.
In Asynchronous phase difference may be different.The
clocks of master and slave are independent.

In Synchronous communication,first three way hand shaking
is needed to stablished the connection.After establishment
of three way hand shaking the communication establish...

While in Asynchronous communication,its not needed.When any
messages comes it broadcast as soon as possible....

In Synchronous comm,it garentted that message will reached
to its desteny in sequential manner...

While in Asynchronous comm,it can't garentted that the
message will reached to its destney or not,its simply
broadcast...

In Synchronous communication,its consists of clk due to
which larger amount of data be transmitted...

While in Asynchronous communication,does not have a clk
signal...

In Synchronous communication,a start and stop bit be
elliminated due to which the faster transmission speed is
acheived...

While in Asynchronous communication,a start and stop bit be
added to each data segment...

In Synchronous communication,it is used in circuit switch
network and speed is 64kbps or 128kbps...

While in Asynchronous communication,it is used in packed
switch network and it consists of speed 38.4kbps

Difference between synchronous & asynchronous communication...

Answer / neha

Synchronous transfer synchronizes the communication between
transmitter and reciever.Chances of error is low over
here.Asynchronous Transfer does not synchronizes between
transmeitter and reciever.Delay is one of the main factors
here.

Difference between synchronous & asynchronous communication...

Answer / rahul gupta

In synchronous communication both ends (sender and receiver)
must be active like mobile communication whereas in
asynchronous communication it require only one end active
who is sender,receiver may me active or deactivate,like
sending mobile sms.

Difference between synchronous & asynchronous communication...

Answer / mahesh babu ummaneni

syncronous means it will sent to claint to total page

but asychronous means it will send perticuler part from the page
ONE MORE DIFERENCE IS:
WHEN WE WANT TO SEND REQUEST IT WILL WAIT UPTO GOT PRIVIOUS RESPONCE
BUT
IN
ASYNCHROUS MEANS ITS NOT BASED ON RESPONCE AGAIN AND AGAIN U CAN SEND REQUEST

Difference between synchronous & asynchronous communication...

Answer / abhishek panwar

synchronous transmission, the stream of data to be
transferred is encoded as fluctuating voltages on one wire,
and a periodic pulse of voltage is put on another wire
(often called the "clock" or "strobe") that tells the
receiver "here's where one bit/byte ends and the next one
begins".

Practically all parallel communications protocols use such
synchronous transmission. For example, in a computer,
address information is transmitted synchronously—the address
bits over the address bus, and the read strobe in the
control bus.
Single-wire synchronous signalling

Synchronization can also be embedded into a signal on a
single wire. In Asynchronous transmission
Main article: Asynchronous communication

In one form of asynchronous transmission, there is only one
wire/signal carrying the transmission. The transmitter sends
a stream of data and periodically inserts a certain signal
element into the stream which can be "seen" and
distinguished by the receiver as a sync signal.

That sync signal might be a single pulse (a "start bit" in
asynchronous start/stop communication), or it may be a more
complicated syncword or self-synchronizing code such as HDLC
or 8B/10B encoding.

Other forms of asynchronous communication use two wires for
each data bit (dual-rail encoding) or one wire for each data
bit and a separate timing wire (bundled data). Both of these
require a separate acknowledge wire.

Obviously, the term "asynchronous" is misleading in its
literal interpretation considering that the
resynchronization problem can be easily rectified...

Difference between synchronous & asynchronous communication...

Answer / sahib

in synchronous communication,first connection between the
two nodes will be established,after establishment the data
transmission will take place

in asynchronous communication no need to check the
connection establishment while sender send the data the
receiver may be ready or may not be ready

in asynchronous sender will send byte of data with one
start bit and one stop bit(one start bit one byte data one
stop bit )

in synchronous communication sender will send block data
without start bit and stop bit

in synchronous communication,we will send the data with clk
reference

in asynchronous no need any clock reference
