An emulator. An emulator is a computer program that duplicates the function of another system. For example, MAME is an emulator application designed to recreate the hardware of arcade game systems in software.
Other than the emulator a ROM image, or simply ROM, of the game is required. The ROM is a computer file which contains a copy of the data from a read-only memory chip, often from a video game cartridge, a computer's firmware, or from an arcade game's main board.
Owning and distributing MAME itself is legal in the US, as it is merely an emulator. The situation regarding ROM images of games is less clear-cut as most arcade games are still covered by copyright.
search for "emulators" or"blah emulator" blah being the system you want to play, nes, genesis, etc...

No. There are currently no functional Xbox 360 emulators.
The PS3 has an emulator that lets it play most PS1 games Some early models with 4 USB ports had hardware and sometimes Partially software Based Emulators to play PS2 games
You can't. Emulator-zone.com offers downloads of emulators. With there emulators you are able to play ROMs of the specific console.
yes there are a number of Playstation emulators most will require you to convert the CD into a downloaded file before it is played

Multiple depending on which software
Emulators are a software emulating another computer. For example, an NES emulator is a software that is ran on a desktop PC to look like the NES (Nintendo Entertainment System), whereas you can play NES titles (Cartridges emulated as ROMs) using your keyboard or a controller for the NES controller. However, emulators are not just for other computers. Technically, an emulator is a piece of software that allows foreign (different language or setup) hardware or software to interact with the current system. The NES example is a good one. An example with software is like installing windows software on linux. It cannot be done due to language conflicts. An emulator solves this problem.
If it is a game, certain emulators could run it. If it is a show, episodes can be downloaded and played with software such as VLC, MPC-HC or Windows Media Player.
No. PlayStation 3 games will obviously not run natively, and as of 2010 there are no functional PlayStation 3 emulators.
It is really hard to say that there is a master emulating software out there but there are some good ones. The only downside to PS2 emulators is that you need an VERY good PC to play them because for some reason it sucks up your processor useage pretty good. So it's not so much the software (Although that does help) but more about your own personal computer. If you have an older computer i suggest upgrading your processor and RAM (if you don't have more than 1gb.) and possibly a graphics card to lessen the load on the CPU. I can't really link you to any of the emulators but I'm sure you can find one your self pretty easy.
You need to disable CD/DVDRom emulators before running the game. Programs such as Daemon tools, Alcohol 120%, as well as many others have been abused for illegal software copying, so some games will search for and detect this software and refuse to run if it finds it, to prevent it's piracy.
