Difference between Cluster and Non-cluster index?

Answer Posted / div

Cluster index directly represents the physically stored
data. So their order will be the same as and when they are
populated into the table. Accessing this data will be
faster.

Non-cluster index just provides a pointer to the data.
Accessing this data will be slower when compared to the
clustered data.
