Bitmap and Vector

Graphics made up of pixels in a grid

Graphics made up of lines and shapes

• BMP
• GIF
• JPEG
• JPG
• PNG
• PICT (Macintosh)
• PCX
• TIFF
• PSD (Adobe Photshop)

• AI (Adobe Illustrator)
• SWF (Flash)
• DXF AutoCAD

A compression format where you don't lose quality because the quality is stored for later

Lossy is a compression type that you do lose quality, the quality is thrown away when you compress

JPEG images, MPEG video/sound

GIF images, lossless WMA

The detail an image holds. Higher resolution means more image detail

Bit depth

A computer graphics term describing the number of bits used to represent the colour of a single pixel in a bitmapped image.

Gives a broader range of distinct colour.

One pixel

The more colour and tones an image has, the greater the bit depth.

Processor speed measures (in megahertz or gigahertz; MHz or GHz) the number of instructions per second the computer executes.

• RAM stands for Random Access Memory.
• It is made up of small memory chips that form a memory molecule. Every time a program is opened, it gets loaded from the hard drive into the RAM. Reading data from the RAM is much faster than reading date from the hard drive.

A printed circuit board that controls the output to a display screen.

A digital camera is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor.

An analog camera is one that uses film rather than some type of electronic sensor, such as a charge-coupled device (CCD) or a complementary metal oxide semiconductor chip (CMOS).

• Linear
• Non-linear
• hierarchical
• composite

• Eg: A short film in order of sequence of events.
• Definition:

Scientific discipline concerned with the understandings, designing and arranging of things so that people can use them safely and easily.

• Line
• Shape
• Size
• Colour
• Texture 
• Value

• Harmony
• Repetition
• Unity
• Balance
• Variety
• Contrast

• Eg: Websites 
• A non-linear storyboard has no particular structure; the user moves between different sections in any direction.

A hierarchical layout is used to define a series of levels and sub levels. This approach is referred to as top down design.

• Eg: Games
• A combination of the other storyboards

a technology consisting of computer components and recording media used to retain digital data.

The motherboard is the main circuit board of your computer and is also known as the mainboard or logic board. Each motherboard has a collection of chips and controllers known as the chipset.

LCD screen, plasma, rear projection, Digital Light Processing (DLP)

a device which can be slotted into a computer to allow the use of audio components for multimedia applications.

a panel of keys that operate a computer or typewritter

A small handheld device which is moved across a mat or flat surface to move the cursor on a computer screen.

(output device) electronic or electromechanical equipment connected to a computer and used to transfer data out of the computer in the form of text, images, sounds, or other media

(input device) data input device: a device that can be used to insert data into a computer or other computational device

Authoring is the process of combining materials such as video, graphics, sound, animation, documents, and files into a format suitable for viewing on the appropriate device. Such devices include DVD players, computers, and the internet.
