PPT-Hamming Code

Rachel Ah Chuen Basic concepts Networks must be able to transfer data from one device to another with complete accuracy Data can be corrupted during transmission For reliable communication errors must be detected and corrected.

Tagged releases need to be scanned for 3. rd. party libraries using CodeInsight. After inventory items are reviewed and all issues mitigated, the final license notification file shall be checked into the tagged release before releasing software. Forward Error Correction.
