Charles is having a lot of problems with errors in a very complicated spreadsheet that he inherited from a colleague, and he turns to another co-worker, Seymour, for tips on how to trace errors in the sheet. Seymour tells Charles that all error values begin with the same symbol, so they can be easily identified as errors.

The symbol is A)#.

Explanation:

• An error is something you have done which is considered to be incorrect or wrong, or which should not have been done.
• Generally errors are classified into three types: systematic errors, random errors and blunders
• Error values begin with the same symbol as they are easy to identify. Once an error is identified, it can be corrected.
• Error correction is the process of detecting errors in transmitted messages and reconstructing the original error-free data. Error correction ensures that corrected and error-free messages are obtained at the receiver side.
• Error Correction can be handled in two ways: Backward error correction: Once the error is discovered, the receiver requests the sender to retransmit the entire data unit. Forward error correction: In this case, the receiver uses the error-correcting code which automatically corrects the errors.
