The term single bit error suggest that only one bit in the given data unit sush as byte is in error.this means that only one bit will change from 1 to 0 or 0 to 1..
In case of burst error,if two or more bits from a data unit such as bte change from 1 to 0 or from 0 to 1 then burst errors are said to have occured.the lenghth of burst is measured from the first corrupted bit to last corrupted bit

Would you expect that the inclusion of a parity bit with each character would change the probability of receiving a correct message?
The inclusion of a parity bit extends the message length. There are more bits that can be in error since the parity bit is now included. The parity bit may be in error when there are no errors in the corresponding data bits. Therefore, the inclusion of a parity bit with each character would change the probability of receiving a correct message.
What is the bit rate a sample rate of a CD?
16/44.1
What is the probability of numbers 5 and above?
The answer depends on what the experiment is and since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.The answer depends on what the experiment is and since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.The answer depends on what the experiment is and since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.The answer depends on what the experiment is and since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
How wide is a 37 inch TV?
3 feet and 1 inch. That is true for the diagonal.If it a CRT and a 3 X 4 screen, it is a bit over 33" wide.If it is HDTV and a 9 X 16 screen, it is a bit over 34.5"
What is STD logic in vhdl?
In VHDL, std_logic is a data type. It is assigned to input and / or output variables. It means that the variable is a standard logic type i. e. a logic bit which accepts or provides one bit data, either 1 or 0.
How can hamming code be used to correct burst errors?
Hamming code is only used for single bit error :/
Single bit error in data transmission?
A single bit error is when only one bit within a given data string is in error. It affects only one character within a message
What do you mean by single bit error correction?
A special system of multiple parity bits (e.g. Hamming parity) that allows not only error detection but limited error correction.Ordinary single bit parity can detect reliably single bit errors.Hamming parity can correct single bit errors and detect reliably double bit errors.
What is the name of the method of error checking that can correct an error in a single bit?
Error-Correcting Code or EEC
What type of transmission do burst errors occur?
In burst error, it is not necessary that only consecutive bits are changed. The length of burst error is measured from first changed bit to last changed bit. As shown in fig. length of burst error is 8, although some bits are unchanged in between. Burst error is most likely to occur in a serial transmission. The noise occurring for a longer duration affects multiple bits. The number of bits affected depends on the data rate & duration of noise. For e.g. if data rate is 1 kbps, a noise of 1/100 second can affect 10 bits.
Which operational characteristic of ram checks for single-bit errors but does not perform error correction?
Parity
Todays memory uses a new method of errors checking called that can detect and correct an error in a single bit?
ECC- error-correcting code
What memory technology ensures reliable data storage retrieval?
ECC error correction code because 98% of errors are single bit
What are the limitations of Hamming Code?
Hamming code handles only single-bit errors-two or more errors will cause an incorrect syndrome value. It can detect double bit error but not corrected
Difference between error control and flow control?
Flow Control:is one important design issue for the Data Link Layer that controls the flow of data between sender and receiver.In Communication, there is communication medium between sender and receiver. When Sender sends data to receiver than there can be problem in below case :1) Sender sends data at higher rate and receive is too sluggish to support that data rate.To solve the above problem, FLOW CONTROL is introduced in Data Link Layer. It also works on several higher layers. The main concept of Flow Control is to introduce EFFICIENCY in Computer Networks.Error Control:Network is responsible for transmission of data from one device to another device. The end to end transfer of data from a transmitting application to a receiving application involves many steps, each subject to error. With the error control process, we can be confident that the transmitted and received data are identical. Data can be corrupted during transmission. For reliable communication, error must be detected and corrected.Error control is the process of detecting and correcting both the bit level and packet level errors.Types of ErrorsSingle Bit ErrorThe term single bit error means that only one bit of the data unit was changed from 1 to 0 and 0 to 1.Burst ErrorIn term burst error means that two or more bits in the data unit were changed. Burst error is also called packet level error, where errors like packet loss, duplication, reordering. BY RAHUL SAGORE from IIPS, INDORE
What is bit error rate?
In a computer system, the bit error rate is based on the percentage of bits transmitted and received compared to those that resulted in error.
What checks the CPU memory and BIOS for errors?
On most currently available computers there is nothing that checks memory for errors. However some more expensive models use RAM modules having either a parity bit or ECC bits. Parity will detect a single bit error. ECC will correct a single bit error (the next time the location is accessed) and detect a double bit error. The BIOS ROM might be checked by a precalculated checksum or CRC code value of the ROM image. But I don't know if this is implemented on current computers or not. The helpfulness of this is questionable as the BIOS itself would have to recalulate this checksum or CRC value on itself, if the ROM was corrupted it is possible this routine is corrupted and won't properly detect and report the error.
