Do you know what a CMS is? Some of us might have heard of it or already know about this, how it works the advantages and disadvantages of CMS - Content Management Systems

A CMS is an alternate way to build and maintain dynamic websites with already available plugins, components and modules to perform several tasks. CMS's can be downloaded and installed on your system to practice and build websites locally, which can then be hosted on a server online. Nowadays web hosting services now come with Install on demand CMS's i.e When you have a hosting plan, you can choose which cms to install on a particular domain. This saves you the stress of pushing the website all you need is build your website online.
With the zeal to know the subject, I downloaded 3 different CMS (Wordpress, Joomla and DotNetNuke). Set them up and got my bearing on each of them. After exploration of all 3, I settled for Joomla. With this I can alternatively build dynamic web applications for leisure or proffesional purposes. Note that different CMS exists for different web scripting languages e.g PHP , ASP.NET
You too can benefit from CMS. Pick up a cms, learn it on your own (might be challenging but it's worth it). Understand the basics then evolve and start building your own web apps with ease. Lastly, CMS's can be known to have lots of advantages, but some open source CMS's have their major drawbacks.
