Each system in a network is called a host, and each connection point in a network is called
a node. At each node, services
exist at two functional levels: network services and distributed systems
services.
You assign a host its host name with the HN (Hostname) system
command. The host name specified with this command becomes active
at the next halt/load.
Network Service Function Levels describes the service functional
levels.

Network services
|
Transfer of information from any point in the network
to some other point in the network.
Any access to a node
in the network is entirely under the control of that node. Thus, each
node is responsible for its security in the network.
One of the functions of Network Services is to control access between
nodes in a network.

Distributed systems services |
Normal access controls defined at the system level.
After a node is established as part of a network, a remote
user or process using the network is still subject to the normal access
controls at the system level.
Remote users must be identified
by a valid usercode or alias usercode designated in the USERDATAFILE
of the local host. The access rights of remote users are controlled
in the same way as the access rights of users on the local host.
