Virtual Reality can be used for immersing yourself in a computer generated environment, this can be used for various forms of simulations and entertainment. Here are a few examples of practical uses in an educational environment:
Virtual Reality is a fully computer generated environment that gives you an immersive experience of being there. Watch the video for more details on how this works:

A 360 photo or video is an image that covers 360 degrees of view. This can be achieved by putting two >180 degrees fish eye cameras back to back, this is how the 'Gear 360' camera works that the RSL currently has. The images are taken separately by the camera and the stitched together afterwards to be viewed. Most 360 cameras like the 'Gear 360' take a 'monoscopic' image which is flat. However high end 360 camera can take 'stereoscopic' images, also known as 3D.

VR - Virtual Reality
HMD - Head Mounted Display
Latency - Latency in VR refers to the time it takes for the computer to render an image and for that image to appear on the HMD. This needs to be as low as possible so when you turn your head quickly the image displayed will be at the same speed. If it's too slow then the image lags behind your movement and it can make you feel sick.
OLED - Organic Light-Emitting Diode. This refers to the display technology used for the screens.
IPD - Interpupillary distance (IPD) is the distance between the center of the pupils of the two eyes. IPD is critical for the design of binocular viewing systems, where both eyepupils need to be positioned within the exit pupils of the viewing system. If your IPD isn't set correctly it can create eye strain.
Frame Rate/FPS - Frames Per Second. The frequency at which frames in a television picture, film, or video sequence are displayed. For VR, the optimal frame rate recommend by Oculus and HTC is 90fps. As a comparison, film and TV run at 24fps.
