How many baud in 300 bytes per second?
Baud is the number of symbols per second. So if you have a parallel interface where the 8 bits are sent together, I guess 300 bytes per second equates to about 300 baud. With a serial interface, where each of the 8 bits is sent one after the other, extra start/stop bits are usually inserted between the 8 data bits, I guess 300 bytes per second equates to about 3000 baud. Baud is the number of changes per second. Since computers use binary number to store information, the baud rate is directly equivalent to the number of bits sent per second. Specifically, in an ASCII character set 8 bits are used to represent a character, 300 bits per second would equate to 37.5 characters per second which in turn is 2250 characters per minute. (just under 2 kilobytes per minute assuming no error correction overheads).
Are there nine bits with an 8-bit even parity setting?
There are at least 9 bits. 8-bit data, even parity, means an extra bit called a parity bit is sent along with the data to make the number of 1's even in the total number (including the parity bit). There might be more than 9 bits, if start/stop or other bits are used in the code. For example, the data value 00000001 (8 data bits), if even parity is used, an extra bit would be sent thus: 100000001 (total number of 1's is 2, even). If the value of the data was 00000011, then the parity bit would have a value of 0, 000000011, so the total number of 1's is even in the entire string. The purpose is so that on the receive side you can use a simple 1-bit adder to do a sanity check on the received data to see if the correct number of 1's was received in a given byte being received. If even parity was sent, and odd parity was calculated on the receive side, that data byte can be flagged as in error and possibly dropped.
Why audio signals are faster than video signals in communication system?
Since audio sounds are sent through the air way it travels through the communication system quicker. The video feed is usually longer because the time it takes to pixelate the picture and load the image correctly.
What are the advantages of paper based communication?
Disadvantages of paper based communication: There are many benefits towards this communication method but they always come at a cost!Issues arise as cost of sending away Via. stamps and delivery, other areas are the writers hand writing quality along with the grammar and spelling mistakes. Some paper based methods do occasionally result in typed up letters printed off and sent away but these letters can include typo's, other mistakes, Etc. Also when you send away a letter to another destination there is always the issue of the time taken to deliver it as it can take among weeks to even months on delivery and many times, the letter is either damaged or returned which can be again a huge issue! Hope this short explanation is helpful(I was already doing a report on this subject and thought id contribute to this WikiAnswers subject) -HiddenFang
What is javascript cokies?
A "Cookie" is a small file that is sent to your computer by websites. Most of the time, they are harmless. They are often used for remembering log-in credentials (Username and passwords), remembering to keep you logged into an account, any many other uses. A "JavaScript" cookie is a cookie sent by the JavaScript language.
Which communication is faster in parallle and serial?
Parallel data transmission is faster compared to serial data transmission. The speed of a parallel link is equal to the number of bits sent multiplied by the bit rate of each individual path.
What do you mean by a serial interface?
Serial means that each bit in a data packet is sent over one wire, one after the other (in chronological order). This is the opposite of parallel, where many bits are sent at once over several wires.
Uart in modem?
UART stands for Universal Asynchronous Receiver Transmitter.UART (Universal asynchronous receiver / transmitter) is responsible for performing the main task in serial communications with computers. This device changes incoming parallel information to serial data which can be sent to communication line. UART is capable of encapsulating a byte that might be 5, 6, 7 or 8 bits wide in start and stop bits. Moreover it can attach an extra parity bit with the data for error detection. The width of stop bits may also vary. UART performs all the tasks, timing, parity checking, etc. needed for the communication.
What is communication overhead?
In the context of computers, communication overhead is those bits of data that must be sent to convey information about, for example, where the information originated and where it is being sent to, how it is to be routed, timestamps, or any other information that is not actually the "payload" representing the actual content to be communicated.
Why is a start bit used in asynchronous communication?
Asynchronous (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 receiver that the byte or packet has ended, and it can check to see if it received the correct number of data bits between the start and stop bits. Think of it this way, if you transmitted 0 asychronously without a start bit, how would the client know a byte had been sent? There would be no state change on the line.
What is the last bit transmitted over a serial connection called?
The last bit is called the stop bit. The entire sequence of bits sent over a serial connection can be found here: http://cnx.org/content/m12293/latest/

What is the difference between a serial port and a parallel port?
Parallel ports are easy to program and faster compared to the serial ports. But main disadvantage is it needs more number of transmission lines. Because of this reason parallel ports are not used in long distance communications. Let us know the basic difference between working of parallel port and serial port. In serial ports, there will be two data lines: One transmission and one receive line. To send a data in serial port, it has to be sent one bit after another with some extra bits like start bit, stop bit and parity bit to detect errors. But in parallel port, all the 8 bits of a byte will be sent to the port at a time and a indication will be sent in another line. There will be some data lines, some control and some handshaking lines in parallel port. If three bytes of data 01000101 10011100 10110011 is to be sent to the port, parallel port communication is faster then serial port.
How computer process bits and bytes?
Bits and bytes are processed into binary code (0 & 1) and are sent to the processor to be processed (hence the name) into the computer's motherboard and is sent to wherever it needs to go.
Data rate of a channel?
A signal's data rate is often confused with its baud rate rate. The two are closely linked but are not identical. The data rate is a measure of how many bytes or bits of data can be sent per second. The baud rate, on the other hand is a measure of how many physical bits are sent per second, including start and stop bits and other idle bits. The baud rate is therefore higher than the data bit rate. A typical asynchronous serial signal that runs at a rate of 9600 baud will carry ten bits for every byte of data sent. One bit is a start bit. Another is the stop bit and the remaining eight are the eight bits of data. The bit rate is actually 8/10 x 9600 = 7680 bits per second. Most transmission methods have an overhead that makes the data rate a little slower than the baud rate. In time critical applications, the difference between them can become significant.
