3.7 Parity Error Checking Curriculum Page
Answer the following questions:
1. Explain how the error card trick from the Error Detection lesson uses a parity scheme. Was it an even or odd parity scheme?
Answer
The card trick uses parity scheme by counting if the rows or columns were even or odd and then finding the error.
2. What are some of the limitations of using parity bits for error detection?
Answer
One problem for this is that it would be harder to find more than 1 problem or error.
3. Another type of error detection is a check sum. Research what a check sum is and then describe it in your own words. Can a check sum identify where an error occurs?
Answer
Check sum is finding the sum of bits. A check sum can find if there is an error, but can't find where the error is.
4. (Optional) Explain in your own words the difference between error detection and error correction. Describe how the error correction process used in the video above allows the computer to fix errors.
