Cpanel is a UNIX-based web hosting control panel with a graphical interface and automation tools designed to simplify website hosting. Cpanel utilizes a 3 tier structure that provides functionality for administrators, resellers, and end-user website owners to control the various aspects of website and server administration through a standard web browser. Cpanel is nothing but a site configuration and management software application. Cpanel hosting is a website that helps individuals or organizations make their web pages available to others.
In addition to the GUI interface, cPanel has a command line and API-based access that allows third-party software vendors, web hosting organizations, and developers to automate standard system administration processes.
Cpanel is designed to function as a dedicated or virtual private server supporting CentOS, Red Hat Linux, and FreeBSD.
CPanel was initially designed as the control panel for Speed Hosting, a now-defunct web hosting company. The original author of Cpanel, John Nick Koston, had a stake in Speed Hosting.
Cpanel is a fully featured, popular web-based hosting account control panel that helps you manage your area or domain and website hosting-related daily tasks for the hosting account owner instead of requesting help from the help desk. This is done through a web browser. The idea is to transfer as much of the control and responsibility of managing your website to you. You can manage all aspects of e-mail files, backup, FTP, etc, without any external help and without doing any tedious programming.
To the client, Cpanel provides front-ends for several joint operations, including managing PGP keys, crontab tasks, mail and FTP accounts, and mailing lists.

Several add-ons exist for an additional fee, including Auto Installers like Installatron, Fantastico, and WHMSonic. Auto Installers are a bundle of scripts that automate web application installation, such as WordPress, SMF, phpBB, Groupware, MagicSpam WHMCS, and ZamFoo. Fantastico is a popular Auto Installer but is losing market fast because of a lack of updates and fewer scripts.

Cpanel manages some software packages separately from the underlying operating system, automatically applying upgrades to Apache, PHP, MySQL, and related software packages. This ensures that these packages are kept up-to-date and compatible with Cpanel but makes it more challenging to install newer versions of these packages.
Web Host Manager (WHM) is a web-based tool used by server administrators and resellers to manage hosting accounts on a web server.

The Cpanel, or control panel, is a popular graphical web hosting and server management control panel. It is a simplified administration of web hosting services and server management.
