What is meant by DJ equipment?

There are two types of DJ equipment. DJs that are hired to come to weddings and other events similar to that to play predetermined or requested music, would typically have lighting, speakers, trusses, computer or music library, cd/media player, and microphone. A DJ that "spins" records in a nightclub would have different equipment than the fore mentioned. This type of DJ would have turntables, a mixer, beat machine, headphones, vinyl records or other music, a computer, and speakers.
