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
This depends entirely on the use of the cable. In a full features RS-232 cable there would be 9 cables. But most hardware that uses a serial cable doesn't have the need for all of these wires so the number may vary. regards, tesseract
Serial ports transmit data one bit at a time, which is why they are becoming obsolete.
BY USING FORMULA (M+R+1)<=2r 011110110011001110101 ---- The formula d + p + 1 <= 2^p (where d is the number of data bits and p is the number of check bits) indicates that we need at least 5 check bits in order to correct single-bit errors in blocks of 16 data bits -- a (21,16) code. SECDED requires 6 check bits for blocks of 16 data bits.
Bitrate: the number of bits per second that can be transmitted along a digital network.
In order to know how many bits/second there are in 1 frame/second, you need to know how many bits are in that frame. In a typical asychronous serial protocol with 8 bits per frame, the bit rate would be 0.125 bits/second. If you are talking the IP network layer of TCP/IP, then the frame size is very dependent on the underlying message payload and headers.The original question, by the way, is invalid. Its asks "how many bits does...", but it should have asked "how manys bits per second does...".
There are 8 bits in a byte.People use a lowercase 'b' to mean "bits" and an uppercase "B" to mean bytes. So if a hard drive has 500GB, that's giga-bytes. But if a network cable lists its speed as 10Mbps, that means 10 mega-bits per second.
As the names imply, a serial port sends data on a small number of wires (often just two wires for the actual data), one bit after the other. A parallel port has many more wires used for data transmission, so many bits can be transmitted simultaneously. The big downside for a serial port is that the "bandwidth" (data bits per second) is very low compared to a parallel port running at the same rate.BUT....parallel data busses have a problem. Electromagnetic interference causes "crosstalk" between the different bits on different data signal lines, and the faster the data rate, the worse the problem gets. Crosstalk causes data transmission errors to occur (a bad thing). So it can actually be a better solution to run a serial data connection at a very, very fast speed than to use a parallel data bus that will have to run at a lower speed (or use more expensive cables and circuitry).In order to do this, each end of the computer bus will use a chip that contains a serial/parallel conversion circuit (SERial/DESerial, or SERDES). This allows the computers to operate on many bits in parallel (byes, words, etc.) but still transmit them in serial over a relatively cheap cable with high data rates.
