The error detection method that involves polynomials is known as Cyclic Redundancy Check (CRC). In CRC, data is treated as a polynomial and divided by a predetermined generator polynomial, with the remainder serving as the checksum. This checksum is appended to the data before transmission, allowing the receiver to perform the same polynomial division to check for errors. If the remainder matches, the data is considered error-free; otherwise, an error is detected.

What is the major drawback of single bit parity check method for error detection?
The major drawback of the single bit parity check method for error detection is its inability to detect errors when an even number of bits are flipped. For example, if two bits in a data unit change, the parity may still appear correct, leading to undetected errors. Additionally, it can only indicate whether an error has occurred, not the location or nature of the error, limiting its effectiveness in error correction.
What is the difference between Error detection and error correction?
In error detection we detect the error.but in error correction we can detect as well as coreect the error both.in error detection we use parity multiplication system i.e even and odd parity.and in error correction we use hamming code as a example.
Which error detection method can detect a burst error?
Cyclic Redundancy Check (CRC) is an effective error detection method that can detect burst errors. It works by applying polynomial division to the data, creating a checksum that is appended to the transmitted data. If a burst error occurs, the CRC will likely fail to match at the receiving end, indicating that errors have occurred. Other methods, like checksums and parity bits, may not be as effective in detecting burst errors.
What are the advantages of CRC error detection method?
The primary benefit of CRC is that it can detect more types of data errors than the other two methods.
4 Give two reasons why network might use an error correcting code instead of error detection and retransmission?
1)Time taken to error correcting is less than doing detection and retransmission. Bandwidth use will be less. 2) In detection and retransmission if back messaging occurs the bandwidth will be more
What is parity in the PC?
In computing, parity refers to a method of error detection used in data transmission and storage. It involves adding an extra bit, known as the parity bit, to a binary number to indicate whether the number of 1s is odd or even. This allows systems to detect single-bit errors; for example, in even parity, if the number of 1s is odd, the parity bit is set to 1 to make it even. While useful for basic error checking, parity cannot correct errors and is often used alongside more robust error detection and correction methods.
Error detection at data link layer is achieved by?
Error detection at data link level is achieved by using a Frame Check Sequence (FCS) method like Parity, Checksum Calculation or Cyclic Redundancy Check (CRC).
What is an error handling error?
Error handling refers to the anticipation, detection, and resolution of programming, application, and communications errors.
What involves a process of trial and error?
Trial and error is a fundamental method of problem solving. It is characterized by repeated varied attempts which are continued until success.SIMPLIFYING FRACTIONSsimplifying fractionsWhen you try to factor a polynomial the most taught method is trial and error. My manipulating the factors you see which terms and coefficients answer the question.
