Your new installation gives you one node of Cassandra, so at present you would have a single-node cluster.
Once Cassandra is started and up and running, you can display your cluster topology with the nodetool status command, it prints the cluster information.

With Cassandra, the data is replicated between nodes according to the replication strategies that you define; in the case of a single-node cluster, replication is not really applicable.
