DVD is a Digital Versitile Disc
VCD is Video CD
The difference is one has multiple layers and so holds more data meaning the movie can be held on a single disc
Bluetooth is a short range wireless networking tool for things like mobile phones etc

DVD is a product made here in the United States. However, VCD is a product made from the asia pacific area. It's like a dvd however it only works on certain DVD. I have both, and I still find DVD to be the one that works best.
Bluetooth is like a form of communication of some kind. When your Cellphone or any device you owned has a bluetooth, you simply find a connection in your device (scrolling down the option tools ) then put it side to side with another bluetooth device (make sure he/she has done the same thing with the connection ) and it will somehow immediately transfer all your stuff (such as songs, pictures etc.) to the other device and vice versa.

1. a. DVD (also known as "Digital Versatile Disc" or "Digital Video Disc") is an optical disc storage media format that can be used for data storage, including movies with high video and sound quality. DVDs resemble compact discs as their physical dimensions are the same (120 mm (4.72 inches) or occasionally 80 mm (3.15 inches) in diameter) but they are encoded in a different format and at a much higher density. The official DVD specification is maintained by the DVD Forum.
1. b. Video CD or VCD, or Compact Disc digital video, is a standard digital format for storing video on a Compact Disc. View CDs, as VCDs are sometimes referred to, are playable in dedicated players, personal computers, and many DVD players.
The VCD standard was created in 1993 by Sony, Philips, Matsushita, and JVC and is referred to as the White Book standard.
2. Bluetooth is an industrial specification for wireless personal area networks (PANs), also known as IEEE 802.15.1. Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers, digital cameras and video game consoles such as the Nintendo Wii via a secure, globally unlicensed short range radio frequency.
The name Bluetooth is derived from the cognomen of a 10th century king of Denmark, Harald Bluetooth. According to the inventors of the Bluetooth technology, Harald engaged in diplomacy which led warring parties to negotiate with each other, making Bluetooth a fitting name for their technology, which allows different devices to talk to each other.[1]. The name of the king in Danish was Harald Blåtand and the Bluetooth logo is based on the H and B runes.

a vcd is only one track and can store about 700 mb
bluetooth is a short-distance connection, like wi fi, used mostly in handheld devices
