A LAN is a Local Area Network, it usually a physical network, either made up of wires (cat5/fiber optics/rg6) or wireless (802.11a/b/g/n - WEP/WPA/WPA2) devices. Basically it is the actual network between all the devices.
DLNA is a protocol that runs over that network (a specific set of instructions or a language that allows the devices to talk to each other). In this case, it allows a media server to talk to media clients. This is most useful for allowing devices like your PS3/XBOX/DVR etc to stream movies from a computer or "server" somewhere else in the house. Programs that allow this include Serviio and TVersity.

There is no difference.
A wired LAN uses wires to connect the computers but a wireless LAN uses radio waves.
They're the same thing. A Local Area Network (LAN) and a workgroup are both a local and they both do the same thing. I think the main difference is that a workgroup is a specific part of the LAN such as a department of a business whereas a LAN describes the network.
Your question doesnt make much sense. Lan technology is the equipment used to make computer networks. There is no LAN standard, there are many "standards" in networking
see link below for answer
they both are exact same...
LAN is internal. IE, your computer, router, modem. WAN is external, such as your computer, a server on the internet, a corporate database. Not to be confused with WLAN, which is wireless LAN
Indeed it could be enabled with DLNA application. You can install ArkMC application on your iPhone - and it would be DLNA enabled. https://itunes.apple.com/us/app/arkmc/id405487397
From the user's point of view, accessing a LAN or WAN is the same. If packets need to be forwarded from a LAN via a WAN connection that is taken care of automatically by the router.
DLNA - Digital Living Network Alliance is a Industry collaboration of group that promotes communication, data transfer between and networking of consumer electronics, mobile phones, computers e.g. for photo transfer between cameras, mobile phones, printers, laptops.
You need a DLNA server, which is software that is running on your PC and a DLNA client which will show content sent by the server. For a good Windows server, check out Mezzmo (http://www.mezzmo.com)
