algorithm: a formula or set of steps for solving a particular problem.
analog: a device or system that represents changing values as continuously variable physical quantities
ASCII: a code for representing English characters as numbers, with each letter assigned a number from 0 to 127
cloud computing: comparable to grid computing, cloud computing relies on sharing resources rather than having local servers handle applications.
cryptography: the art of protecting information by transforming it into an unreadable format, called cipher text
digital: any system based on discontinuous data or events. Computers are digital machines because at the basic level they can distinguish between just two values, 0 and 1.
digital signal processing: (DSP) refers to manipulating analog information
download: to copy data (usually an entire file) from a main source to a peripheral device
lossless compression: data compression techniques in which no data is lost.
lossy compression: data compression techniques in which some amount of data is lost. This technique attempts to eliminate redundant information.
megabyte: used to describe data storage, 1,048,576 bytes (abbreviated MB)
megapixel: one million pixels, used in reference to the resolution of a graphics device
modeling: process of representing a real-world object of phenomenon as a set of mathematical equations.
OCR: optical character recognition, the branch of computer science that involves reading text from paper and translating the images into a form that the computer can manipulate
pixel: short for a picture element, a single point in a graphic image
raster: the rectangular area of a display screen actually being used to display images
render: refers to the process of adding realism to a computer graphics by adding 3-D qualities, such as shadows and variations in color and shade.

steganography: the art and science of hiding information by embedding messages within other, seemingly harmless messages
