## Node ## Node
In **Etcd**, the **Node** is the rudimentary element constructing the whole. In **etcd**, the **node** is the base from which the filesystem is constructed.
Currently **Etcd** file system is comprised in a Unix-like way of files and directories, and they are two kinds of nodes different in: **etcd**'s file system is Unix-like with two kinds of nodes: file and directories.
- **File Node** has data associated with it. - A **file node** has data associated with it.
- **Directory Node** has children nodes associated with it. - A **directory node** has child nodes associated with it.
Besides the file and directory difference, all nodes have common attributes and operations as follows: All nodes, regardless of type, have the following attributes and operations:

Each node has various meta-data, including three names of access control lists used to control reading, writing and changing (change ACL names for the node).
