Answer:

In RAID 2 Hamming Code ECC Each piece of the information word is kept in touch with an information plate drive . Every datum word has its Hamming Code ECC word recorded on ECC circles. On Read, the ECC code confirms the right information or revises the single plate blunders.  

Strike Level 2 is one of the two innately equal mapping and assurance strategies characterized in the Berkeley paper. It has not been broadly sent in the business to a great extent since it requires an extraordinary plate highlights. Since plate creation volumes decides the cost, it is increasingly practical to utilize standard circles for the RAID frameworks.  

Points of interest: "On the fly" it gives information blunder amendment. Amazingly high information move rates is possible.Higher the information move rate required,better the proportion of information circles to ECC plates. Moderately basic controller configuration contrasted with the other RAID levels 3,4 and 5.  

Impediments: Very high proportion of the ECC plates to information circles with littler word sizes - wasteful. Passage level expense are extremely high - and requires exceptionally high exchange rate prerequisite to legitimize. Exchange rate is equivalent to that of the single plate, best case scenario (with shaft synchronization). No business executions can't/not industrially suitable.

  • You can also right-click the connection and click Disconnect on the context menu

  • The SQL EXECUTE command executes an SQL command and binds the result to 4D objects (arrays, variables or fields).
  • A valid connection must be specified in the current process in order to execute this command. The sqlStatement parameter contains the SQL command to execute.
