Key terms—animation, bit-map versus vector graphics, object-oriented, clip art, CAD, hypermedia, hypertext, pixel, resolution, MP3, MIDI, morph by Ken Moyer

Animation is the rapid display of a sequence of 2-D artwork or model positions in order to create an illusion of movement. It is an optical illusion of motion due to the phenomenon of persistence of vision. This could be anything from a flip book to a motion picture film.
Bitmap, is a data file or structure representing a generally rectangular grid of pixels, or points of color, on a computer, paper, or other display device. On the other hand, Vector graphics is the use of geometrical primitives such as, points, lines, curves and polygons, which are all based upon mathematical equations to represent images in computer graphics.

Object-oriented programming (OOP) is a progaramming paradigm that uses "objects" to design applications and computer programs. Paradigm by definition means one that serves as a pattern or model. Today, many popular programming languages (such as Java, JavaScript, C#, C++, Python, PHP, Ruby and Objective-C) support OOP.

Clip art refers to pre-made images used to illustrate anthing. Today, clip art is used extensively in both personal and commercial projects. They range from home-printed cards to advertisement. Clip-arts can also be in both electronic or printed form. It can be very convieniently used.

Computer-aided design (CAD) is the use of a alot of computer-based tools that assist engineers, architects and other design professionals with their design activities. This will help design, develop and create products that will be goods used by consumers or intermediate goods used for other products.

Hypermedia is used as a logical extension of the term hypertext, in which graphics, audio, video, plain text and hyperlinks intertwine to create a generally non-linear information. The World Wide Web is a classic example of hypermedia because it has all of the characteristics I just menationed in my defintion of hypermedia. Hypertext is a method of storing data through a computer program that allows a user to create and link fields of information and to retrieve the data. The most frequently discussed form of hypertext document contains automated cross-references to other documents called hyperlinks. Selecting a hyperlink causes the computer to load and display the linked document.

A pixel is a single point in a graphic image. A pixel is not really a dot, nor a square, but an abstract sample. With care, pixels of an image can be created at any size without the appearance of visible dots or squares. But in many contexts, they are reproduced as dots or squares that can be visibly distinguished when the graphics are not fine enough.
Resolution is the act, process, or capability of distinguishing between two separate but adjacent objects, sources of light, or between two nearly equal wavelengths. resolution can be measured in various ways. Basically, resolution quantifies how close lines can be to each other and still be visibly.

MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a popular digital audio designed to greatly reduce the amount of data required to represent audio. Although the amount of data required is reduced, most music will still sound like a faithful reproduction of the original uncompressed audio to most listeners.

MIDI (Musical Instrument Digital Interface) is an industry-standard electronic communications protocol that enables electronic musical instruments, computers and other equipment to communicate and control each other in real time. MIDI does not transmit an audio signal. It simply transmits digital data such as the pitch and intensity of musical notes to control signals for parameters such as volume, vibrato and panning, and clock signals.
Morphing is to to transform by computer, usually an image. Most often it is used to depict one person from turning into another through some magical or technological means.
