The Document Object Model (DOM) is a programming interface for HTML and XML documents

It represents the page in a tree structure so that programs can read, access and change the document structure, style, and content

The DOM is an object-oriented representation of the web page, which can be modified with a scripting language such as JavaScript.

Every web browser uses some document object model to make web pages accessible via JavaScript

How to Find Ulimit For user on Linux

How can I find the correct ulimit values for a user account or process on Linux systems?

For proper operation, we must ensure that the correct ulimit values set after installing various software. The Linux system provides means of restricting the number of resources that can be used.

For example, if certain thresholds are too low, the system might not be able to server web pages using Nginx/Apache or PHP/Python app. System resource limits viewed or set with the NA command. Let us see how to use the ulimit that provides control over the resources available to the shell and processes.
