What is tethered shooting? In a nutshell, it consists of wiring up the camera to a personal computer, typically a laptop, and use extra software that identify the camera and pulls images as they are shot to display them on the computer screen.

Why would you do that? There are fullness of good reasons. First, reviewing images on a computer display is much more comfortable than doing so on the camera's tiny Lcd; if viewing relax is foremost to you, tethering shooting might just be the ticket.
Next, you could use a projector to broadcast images on a big screen, which is great for social event, photo seminars or ceremonies... Applications are plenty.
Finally, the tethering software - by downloading the photo just after they are shot - provides you with an instant backup of the images. Depending on the software's abilities, you can also rate the images or delete the bad one on the fly, greatly speeding up the comprehensive workflow.
What do you need to get started? First, the camera must sustain tethered operations, typically by the way of the Mtp/Ptp protocol. Most contemporary Dslr cameras from major manufacturers sustain this mode. If your camera is less than 2-3 years old, chances are that it supports Ptp already, check your camera's manual to find out, it should be in the section describing the Usb connectivity.
Next you need an Usb 2.0 cable long adequate to give you the leisure of movements required by the conditions and your shooting style. The Usb 2.0 acceptable limits the maximum cable length to 5 meters (15 feet) but it is easy to find Usb 2.0 extenders/repeaters that allows much longer distances between the camera and the computer.
Last, you need a software application to download and display the pictures. Here the choices depend on the platform your computer is running on. Sometimes the camera ships with tethering software in the box, sometimes you must buy dedicated software from the camera manufacturers. Additionally, some third party software developers offer tethering clarification for most cameras, on both the Pc and Mac platforms.
Some of them allow you to remotely control the camera, for example to fire the shutter by clicking a button on the computer, in expanding of the download and display functions described above. The most involved solutions requires you to setup the file download in one utility, then the image viewing in another, while the simpler ones offers integrated functions performing both the transportation and the viewing within the same application.
