# Overview

A node is a networked ArcSight product that can be centrally managed through ArcSight Management Center. Each node is associated with a single networked host which has been assigned a hostname, an IP address, or both.

Node types can include any of the following ArcSight products:

Management of Fusion ArcMC is not supported.

- Connector Appliances or Software Connector Appliances

- Logger Appliances or Software Loggers

- Containers, connectors, or Collectors

- Other ArcSight Management Centers, either software or Connector Hosting Appliances

- Transformation Hub

A single host, such as a single deployed Transformation Hub, can comprise multiple nodes for management purposes. In addition, a node can be in a parent or child relationship with other nodes.

You can perform any of the following node management tasks:

- View managed nodes by location, by host, or by node type.

- Add, view, edit, and delete locations for hosts.

- Add nodes from a host, import hosts from a CSV file, view and delete hosts, view all hosts in a location, update software on hosts, move hosts to different locations, and scan hosts for new connectors or containers.
