Steam is a gaming network and valve is a company, but what else? I think that it might be nothing; they both suck at working.
I don't understand this question fully, but I think you like my answer: Steam is a software for gaming articles, but it also meaning gas on another word. Valve (www.google.rs/search?q=Valvehl=srclient=firefox-ahs=SCurls=org.mozilla:en-US:officialprmd=imvnssource=lnmstbm=ischei=8zHfTr2iIsKnhAeTy-yVBQsa=Xoi=mode_linkct=modecd=2ved=0CCgQ_AUoAQbiw=800bih=393) is a legal company, same as meaning the link I put there. Hope it helps! :)
