Horizontal and vertical parity check

Click For Summary
SUMMARY

This discussion focuses on detecting errors using horizontal and vertical parity checks, specifically employing even parity. The user seeks assistance in identifying an error in a given data set, which is indicated by incorrect parity bits in the corresponding row and column. The conclusion drawn is that the absence of an error may stem from a misunderstanding of the task, which might require generating an error indication rather than identifying an existing one.

PREREQUISITES
  • Understanding of even parity checks
  • Knowledge of error detection techniques
  • Familiarity with data representation in rows and columns
  • Basic concepts of parity bits
NEXT STEPS
  • Study the implementation of horizontal and vertical parity checks in data transmission
  • Research error detection algorithms beyond parity checks
  • Learn about generating artificial errors for testing error detection systems
  • Explore the limitations of parity checks in error detection
USEFUL FOR

This discussion is beneficial for computer scientists, network engineers, and anyone involved in data integrity and error detection methodologies.

Hello. I need help in detecting error. The question in the attached file is to first fill in the blanks with vertical and horizontal parities. Secondly, it says that there is an error in the circled part. My problem is, how do I find that error and why is there an error? In the second image, I show you that I have answered question no. 1.

You are using even parity checks.

You would normally detect an error in a single bit because the parity check bits are wrong for the corresponding row and column.

From the information that you have provided there is no error; perhaps the problem asked you to _generate_ an error indication for that bit?
