What are nodes in servers?
Server nodes run services or back end applications that access data on the shared external disks. Client nodes run front end applications that retrieve data from the services provided by the server nodes. Client nodes can run PowerHA SystemMirror software to monitor the health of the nodes, and to react to failures.

What is the purpose of a node?
Node allows developers to write JavaScript code that runs directly in a computer process itself instead of in a browser.

What is a node in Linux?
Nodes are usually connected by fast local area networks, with each node running its own instance of Linux. Nodes may be physical or virtual machines, and they may be separated geographically. Each node includes storage capacity, processing power and I/O (input/output) bandwidth.
Why is inode important?
The inode contains all the administrative data needed to read a file. Every file’s metadata is stored in inodes in a table structure. When using a program that refers to a file by name, the system will look in the directory entry file where it exists to pull up the corresponding inode.

What are the four types of nodes?

- technical root node (see Section 1, “The technical root node”),
- atomic nodes (see Section 2, “Atomic nodes”),
- paratactic structure root nodes (see Section 3, “Paratactic structure root nodes”),
- list structure root nodes (see Section 4, “List structure root nodes”),
What are node types?
A node type is a collection of an application’s nodes that share a common business purpose. Use node types to define nodes’ properties and to define rules that convert a node type to another node type. Each node is a member of a node type.
