1, (serial means in series therefore in a series only one bit of information passes at a time) - the opposite is 'in parallel'.

one bit at a time
The maximum effect of a 2-ms burst of noise on data transmitted at 14 kbps can be calculated by determining how many bits are transmitted during that time. At 14 kbps, 2 ms corresponds to 28 bits (since 14,000 bits per second multiplied by 0.002 seconds equals 28 bits). Therefore, a 2-ms burst of noise could potentially disrupt up to 28 bits of data, impacting the integrity of the transmitted information depending on the error correction and detection mechanisms in place.

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
The physical layer of the OSI model does not operate with a specific number of bits, as it deals with the transmission of raw binary data over physical media. Instead, it is concerned with the characteristics of the physical connection, including voltage levels, timing, and signaling methods. Data is transmitted as a series of bits, but the physical layer itself is focused on how these bits are represented and transmitted over the medium.
The maximum effect of a 2-ms burst of noise on data transmitted at 12 kbps can be calculated by determining how many bits are transmitted during that time. At 12 kbps, 2 ms corresponds to 24 bits (since 12,000 bits per second multiplied by 0.002 seconds equals 24 bits). Therefore, a 2-ms burst of noise could potentially corrupt or disrupt the transmission of up to 24 bits of data, depending on the nature of the noise and the error correction mechanisms in place.
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.
