In advance operating system what is process synchronization?
In computer science, especially parallel computing, synchronization means the coordination of simultaneous threads or processes to complete a task in order to get correct runtime order and avoid unexpected race conditions. There are many types of synchronization: * barrier * lock/semaphore * non-blocking synchronization * synchronous communication operations advantages of synchronous communications are * no need of start and stop bits * higher data rates possible * the actual data length need not be fixed
How fast is 200 kbps?
200,000 bits of information a second. A data byte has 8 data bits, a start bit and one or two stop bits.
What is the purpose of a start bit in rs232 serial communication protocol?
start bit signals receiver end to receive sequence of bits(data bits) and stop bit to signal the end of bit transmission.
Why is it that the start and stop bits can be eliminated when character interleaving is used in synchronous TDM?
Because it reassigns time slots and fix it
Can an error 54 cause a car to stop and not start again How can it be fixed?
don,t know if this helps, but code 54 means there is no camshaft position signal / or a problem with the camshaft synchronization circuit.
A Suppose that a sender and receiver use asynchronous transmission and agree not to use any stop elements Could this work?
Not for asynchronous transmission. The stop bit is needed so that the start bit can be recognized as such. The start bit is the synchronization event, but it must be recognizable. The start bit is always a 0, and the stop bit is always a 1, which is also the idle state of the line. When a start bit occurs, it is guaranteed to be different from the current state of the line.
What is the efficiency of ascii character using asynchronous data with two stop bits?
The efficiency of ascii characters using asynchronous data transfer protocol with two stop bits is 8 in 11, or 72%. There is one start bit, eight data bits*, and two stop bits. That is 11 bit cells, in which a payload of 8 bits is possible, hence the 8 in 11. *Actually there are only 7 data bits in ASCII... latin-1 and several other incompatible extensions to ASCII have 8. Which one is in use varies between languages - many European countries use different encodings which have the same meanings for the first 128 characters but different for the second 128 depending on what extra characters are required in the language in question. If the payload was 7 bits, for pure ASCII, then the efficiency with one start bit and two stop bits would be 7 in 10, or 70%.
What are the similarities and differences between synchronous and asynchronous transmission modes?
Asynchronous transmission refers to the case when the sending initiate transmission of byte at any instant of time. In asynchronous transmission only one byte is sent at a time and there is no time relation between consecutive bits. This transmission is also referred to as start-stop transmission.This is achieved by providing two extra bits, a start bit at the beginning and a stop bit at the end of a byte. The start bit always "0" and is prefixed to each byte. The stop bit is always "1" and also suffixed to each byte usually 1,1.5 or 2 bits.ANSWERED BY= SATISH KUMAR (AKASH VERMA) [LUCKNOW UNIVERSITY LUCKNOW]
Explain the type of error which will be detected when using parity error checking on a serial link?
if the stop bits does not appear when it is supposed to, the UART considers the entire word to be garbled and will report a framing error regardless of the whether the data was received correctly or not, the UART automatically discards the start,parity and stop bits.
What is a pneumatic braking system?
Pneumatic braking system utilizes compressed air to stop the motion in vehicles.
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 character framing?
Character refers to the total number of bits used to transmit a character. This includes the length of the coded character and the number and type of overhead bits required for transmitting it. A common character-framing scheme calls for a start bit, seven data bits, an odd-parity bit, and a stop bit. An additional bit is often added to the frame for error-checking purposes.
