RAM
RAM is a type of computer storage whose contents can be accessed in any order. This is in contrast to sequential memory devices such as magnetic tapes, discs and drums, in which the mechanical movement of the storage medium forces the computer to access data in a fixed order. It is usually implied that RAM can be both written to and read from, in contrast to read-only memory or ROM.
Computers use RAM to hold the program code and data during execution. In the first electronic computers, RAM wa... |

DPI
A measure of image resolution - typical screen resolution is 72 dip whereas printing presse print at 300dpi.
When measuring the resolution of an image you need to know both the physical size and the resolution (in DPI) to acertain the actual amount of data. For example: An image that is 10 inches wide... at 72dpi would be 720 pixels wide at 300dpi would be 3000 pixels wide (roughly 3.5 times the resolution) |

JPEG
A compressed graphics format specifically designed for photographs. Itīs name an acronym that stands for Joint Photographic Experts Group. It works by changing the images data from colours to frequencies (that represent detail) using a FFT and then discarding some of the high detail data - the resulting image is slightly blurry but this is barely noticable by the human eye and represents a significant saving of space.
