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
Image resolution refers to?
The detail an image holds. Higher resolution means more image detail
Colour depth is also referred to as...?
What is bit depth?
A computer graphics term describing the number of bits used to represent the colour of a single pixel in a bitmapped image.
Higher colour depth does what?
Gives a broader range of distinct colour.
One bit represents?
Each pixel has colour and tone, what effect does this have?
The more colour and tones an image has, the greater the bit depth.
What is the processor speed?
Processor speed measures (in megahertz or gigahertz; MHz or GHz) the number of instructions per second the computer executes.
What is RAM?
- 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.
Define Graphics card
A printed circuit board that controls the output to a display screen.
What is a digital camera?
A digital camera is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor.
What is an analog camera?
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).
What are the types of storyboards?
What is a linear storyboard?
- Eg: A short film in order of sequence of events.
Scientific discipline concerned with the understandings, designing and arranging of things so that people can use them safely and easily.
List some elements

What is a non-linear storyboard?
- Eg: Websites
- A non-linear storyboard has no particular structure; the user moves between different sections in any direction.
What is a hierarchical storyboard?

What is a composite storyboard?
- Eg: Games
- A combination of the other storyboards
What is storage?
a technology consisting of computer components and recording media used to retain digital data.
What is the motherboard?

Define output devices
(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
Define input devices
(input device) data input device: a device that can be used to insert data into a computer or other computational device
What is authoring?
