Question

Which of these error-detecting codes enables to find double errors in Digital Electronic devices?

• A. Bit generation method
• B. Odd-Even method
• C. Parity method
• D. Check sum method

Hint:

Different error detection methods have different capabilities and limitations. Checksum is capable of detecting double errors but does not correct them.

Answer 1

The Correct Option is D

The Check sum method is capable of detecting double errors in digital electronic devices. It works by adding all the data together and creating a checksum which is sent along with data. If the checksum at the receiving end doesn't match with the calculated sum, it means there is some error. The checksum can also sometimes detect multiple errors depending on the nature of errors, but it is not guaranteed.
