file permissions

File permissions control the ability of the users to view or edit the file.

Files and directories have permissions that specify who can read, write, modify and access them.

Each file or directory has three basic permission types:

1. The read permission allows to read the content of the file.

2. The write permission allows to modify a file.

3. The execute permission allows to execute the file.

When a permission is not set, the corresponding rights are denied.

Every file system has files and folders permissions.

The web server needs to be able to read your web pages in order to be able to display them in a browser.

Therefore permissions need to be set in order to make your web site function properly.
