DLNA vs UPnP in digital Home | What is DLNA certified in Digital Living?

DLNA and UPnP are both Digital Home interoperability networks for PCs, laptops, tablets, smartphones and consumer electronics. In recent years, especially the past two years, home networking and digital sharing at home have become essential and popular. 
The DLNA (Digital Living Network Alliance) was created to solve these problems and produce an independent directive accepted by suppliers and accepted worldwide for manufacturers in terms of digital home interoperability. 
Basically, this concept was created and developed by UPnP (Universal Plug and Play) in 1999 with 14 main manufacturers. UPnP is a TCP / IP based development for network connectivity using HTTP, HTML, XMP and SOAP to discover devices, device control, and the description and service of the service. It is the foundation of DLNA which was created in 2003 with 21 companies. 
DLNA has standardized interoperability in the digital home and provides certification to manufacturers if they comply with DLNA standards. Most devices are marked as DLNA certified, which means that regardless of the manufacturer, they will operate on the home network.
