The full form of ECC is ” Error Correction Code .” ECC is used to verify data transmissions in which transmission errors are detected and corrected.
It is commonly used by RAM chips under which forward error correction (FEC), which ensures that all the data that is sent to and from RAM is properly transmitted or not.
ECC RAM or memory is also very similar to parity RAM, in which a parity bit is also mehud, which validates whether the data is being sent or not.
This parity bit is a redundant binary value of 1 or 0 that is sent with data.
If the parity bit does not match the value of the data that it represents, then it represents an error has occurred in the transmission and therefore the data may have to be sent again.
ECC also works in the same way, but it uses a more advanced error correction system that can easily fix data transmission errors.
Since ECC memory requires more processing, it may be slightly slower than non-ECC RAM and basic parity RAM.
But still ECC RAM provides more reliable data transfers, which results in greater system stability. Therefore high-end servers and workstations use ECC memory to minimize (reduce) crashes and system downtime.
