for 8 bit synchronous serial transmission total transmitted characters will be
1200/8
and for asynchronous transmission with 1 stop total bit will be (8+1+1=10) i.e. (8 bit + start bit+stop bit)
so transmitted characters will be
1200/10

Difference between synchronous and Asynchronous serial communication in micro controller?
Synchronous: The synchronous format, receiver or transmitters are synchronized. A block of information is transmitted along with the synchronization information. This is clk oriented transmission format. This information is specially used for high speed transmission. Usually in this synchronous system one or two SYNC character are used for data synchronous data system. Transmission device send data continuously to receiving device. If the data is not ready this system continuously synchronous data until the data is unviable. Asynchronous: It is character oriented. Each character comes with the information of start and stop. In this system 1 for mark, 0 for space. When data are being transmitted a receiver stay at high at logic 1. This is specially used in low speed transmission.
What is the definition for Asynchronous communication?
In telecommunications, asynchronous communication is transmission of data, generally without the use of an external clock signal, where data can be transmitted intermittently rather than in a steady stream
Differences between asynchronous connections synchronous and isochronous connections?
These are all methods used to transfer streams of data. Waveform diagrams can be used to illustrate these different transmission modes. A waveform diagram shows how the signal might appear on an oscilloscope screen, which produces a diagram with voltage on the vertical axis and time on the horizontal axis.SynchronousBits in a synchronous data stream must be transferred in sync with a clock signal. The control signals for the data are derived from a clock signal. Synchronous data transfer systems usually have an error detection mechanism. If an error is detected the data can be resent.AsynchronousBits in an asynchronous data stream can be transferred at random intervals and the data rate of the stream is not required to be constant. Asynchronous systems use a start bit to signal the beginning of a data transmission. A stop bit is used to signal the end of a data transmission. Asynchronous data transfer systems usually have an error detection mechanism. If an error is detected the data can be resent.Isochronous (pronounced "eye-sock-ron-us")An isochronous data transfer system combines the features of an asynchronous and synchronous data transfer system. An isochronous data transfer system sends blocks of data asynchronously, in other words the data stream can be transferred at random intervals.Each transmission begins with a start packet. Once the start packet is transmitted, the data must be delivered with a guaranteed bandwidth. Isochronous data transfer is commonly used for where data must be delivered within certain time constraints, like streaming video.Isochronous systems do not have an error detection mechanism (acknowledgment of receipt of packet) because if an error were detected, time constraints would make it impossible to resend the data.
What is the difference between synchronous and asynchronous data transmission?
Both of these forms of communication are a means of transmitting data. The difference is in the format that the data is transmitted. Asynchronous communications is the method of communications most widely used for PC communication and is commonly used for e-mail applications, Internet access, and asynchronous PC-to-PC communications. Through asynchronous communications, data is transmitted one byte at a time with each byte containing one start bit, eight data bits, and one stop bit, thus yielding a total of ten bits. With asynchronous communications, there is a high amount of overhead because every byte sent contains two extra bits (the start and stop bits) and therefore a substantial loss of performance. Synchronous communications is the more efficient method of communications. CQ's connectivity solutions communicate through the synchronous method of communications. Through synchronous communications, data is transmitted as frames of large data blocks rather than bulky individual bytes. One advantage of synchronous is that control information is easily inserted at the beginning and end of each block to ensure constant timing, or synchronization. Another advantage of synchronous is that it is more efficient than asynchronous. For example, a 56 Kbps dial-up synchronous line can carry 7000 bytes per second (56000/8) compared to a 56 Kbps dial-up asynchronous line which can only carry 5600 bytes per second (56000/10). When transmitting large amounts of information, this translates into a significant increase in speed and performance. To see this work you can work out the efficiency rates and time that it takes to send each message Asynchronous would be worked out as follows To get the efficiency of it you get assuming the message is being send over a 100mb line and 70 bytes to send and 300 characters then it is 70*8 = 560 (the 8 is for the 8 bits to make up each byte) the 70*2 (the start and stop bit) =140 = 700 then to get 560*100/700= 80 that means that 80% efficient To get the time Asynchronous 300 *(1+7+1+1) =3000 take this and divide it by the size of the line in this case 100mb so that is then 3000/100=30 that means that it would take 30 seconds to send for synchronous efficiency Then 70*8= 560 then 4 bytes = 4*8 (the over head bits) = 32 560+32=592 560*100/592=94.5 then that's 94.5% efficient and for the time then it is just 300+4*8=2342/100=23.42 that's then 23.42 seconds this shows you which is faster and more efficient in each case
State three forms of data transmission characteristic and explain each of them?
Parallel transmission is when multiple wires connect each sub-unit and data is exchanged simultaneously on separate lines. Serial transmission is when the bits of data are transmitted one after another. Asynchronous transmission is when only one character at a time or one byte at a time is sent.
Why sonet is used?
SONET (Synchronous Optical Networking) is used for high-speed telecommunications networks to provide reliable and efficient data transmission over fiber optic cables. It offers synchronous data transmission, enabling multiple data streams to be multiplexed and transmitted over a single optical fiber. SONET is commonly used in backbone networks to support high-bandwidth applications such as video streaming, internet connectivity, and phone services.
What is a sentence for transmitted?
We have transmitted the signal.She transmitted the disease to her lover.
In AM transmission the frequency which is not transmitted is?

What is the adjective form of Transmission?
Transmissible
What is the difference between synchronous and asynchronous cryptography?
in synchronous communication data will be transmitted with clock and in asynchronous only start and stop bit is required for transmission of databut speed of the data transmission in synchronous is very high data rateand in asynchronous speed is slow due to the start and stop bit
What is cultural transmission?
Cultural transmission refers to the process by which knowledge, beliefs, practices, and values are passed from one generation to another within a society. It involves the transfer of information through social learning, imitation, and communication, shaping the cultural norms and traditions of a community over time.
