How clients reach Teradata system?

Each Teradata node has an IP address

Client machines use hosts file windows/system32 directory. where we
list teradata nodes using specific syntax

nodeipaddress tpdidcop{1,2,3...etc}

Ex:

172.64.127.51 teradatanode1cop1
172.64.127.52 teradatanode2cop2
172.64.127.53 teradatanode3cop3

Then Client tries to connect one by one. Client may reach any one node
and the software in the node assigns a PE from any node after looking
load balancing
