WordPress is a free and open-source content management system based on PHP and MySQL. To function, WordPress has to be installed on a web server, which would either be part of an Internet hosting service or a network host in its own right.
WordPress is the most popular website management or blogging system in use on the Web, supporting more than 60 million websites. WordPress has also been used for other application domains such as pervasive display systems.
A freelancer is a term commonly used for a person who is self-employed and is not necessarily committed to a particular employer long-term. Freelance workers are sometimes represented by a company or a temporary agency that resells freelance labor to clients.
