WebA shard is a replica set that contains a subset of the cluster’s data. The mongos acts as a query router for client applications, handling both read and write operations. It dispatches client requests to the relevant shards and aggregates the result from shards into a consistent client response. WebWhen a request for a program operation arrives from the controller, a row of the memory array ( corresponding to the requested page) is selected and the latches in the page buffer are loaded with the data to be written. The SST is then turned on while the GST is turned off by the control unit.
