Error in a binary stream or object can be detected using Error detection techniques. (usually called EDC, or error detection and correction)

Errors can be detected in many ways, but they all involve adding some redundant data along with the original message. The process for calculation of these bits is repeated while checking, and if there is a match, the data is accepted, else it is rejected (which usually involves applying data correction, or request to resend the data)

Type of error detection are :

  1. Block repetition : same data is repeated twice, and at the receiver's end, checked if they are exactly the same
  2. Parity bits : a single bit is added after the sequence of certain number of data bits, to make the data's parity even or odd, depending upon the selection made.
  3. Checksum : Mathematical formula involving all bits of the data is applied, obtained result is the redundant bit, which is added for detection. Receiver recalculates and then compares the data for detection.
  4. CRC (Cyclic Redundancy Check) : another mathematical formula where all bits are used.
  5. Hash functions : predetermined hash functions for calculating the error detection code

How to propagate error when averaging data points?

To propagate error when averaging data points, calculate the standard error of the mean by dividing the standard deviation of the data by the square root of the number of data points. This accounts for the uncertainty in the individual data points and provides a measure of the uncertainty in the average.


What are some of the sources of error in your analysis?

Some sources of error in analysis can include data collection inaccuracies, incomplete data, biased sampling methods, human error in data entry or analysis, and assumptions made during the analytical process.


What is the difference between BPSK and DPSK?

BPSK=> 1.The BPSK stands for “Binary Phase-shift keying”. 2.DPSK is a not a method of BPSK, where there is no reference phase signal. 3.amplitude shift keying 4.lesser bandwidth more probability error DPSK=> 1.The DPSK stands for “Differential phase-shift keying”. 2.DPSK is a method of BPSK, where there is no reference phase signal. 3.It is one type of phase modulation used to transmit data by altering the carrier wave’s phase. 4.greater bandwidth probability error less


What is the advantage of simple parity check?

Simple parity check is easy to implement and helps to detect single-bit errors in data transmission. It is a simple and fast error detection technique that adds minimal overhead to the data being transmitted. However, it is limited in its ability to detect multiple bit errors or correct any errors detected.


What is the advantage of checksums?

Checksums provide a way to verify the integrity of data by generating a unique value based on the data. By comparing this value before and after data transmission, errors or tampering can be detected. This helps ensure data accuracy and reliability.

What is binary used for in a network?

Binary is used in networks to represent data in a format that computers can understand and process. It serves as the fundamental language for encoding information, including text, images, and instructions, into sequences of 0s and 1s. This binary data is transmitted across networks, enabling communication between devices through protocols that interpret and manage these binary signals. Additionally, binary is crucial for error detection and correction methods that ensure reliable data transmission.
