I made this penguin using Inkscape

   What number system is digital data based on? What two digits are used to code all digital data?

Digital data is based in the binary code. The binary code is made up of the numbers 0 and 1

What is a bit?

A bit is the smallest piece of information

 What is a byte?

Eight bits make one byte

What is “sampling rate”?

The sampling rate is the number of samples per second taken from a continuous signal to make a discreet signal

How does Colour Depth (Color Depth) or bit depth effect the appearance of an image?

Colour depth refers to the number of bits of computer memory needed to store colour information for an image.

• 1-bit allows monochrome or 2 colors. (black and white)

• 2-bit allows 4 colors.
• 4-bit allows 16 colors.
• 8-bit allows 256 colors.
• 16-bit allows 65,536 colors.
• 24-bit allows 16,777,216 colors.

The more bits there are, the more colours you can have

  Colour depth effects both still and video digital media. Sampling rate only effects video but not still media. Can you explain.

Sampling rate only affects video because there are many pictures, and audio to be sampled as samples per second, while still media doesn't have a sampling rate because there is only one picture (not multiple pictures per second)

The Drawing Tools In Inkscape

The Drawing Tools In Word

Painting Tools



Rectangle Select

This tool is used to define a rectangle or square selection region

 Move Selected Pixels

This is used to move pixels that are selected

Lasso Select

This is used to draw a freeform selection region

Move Selection

Used to move the selection without affecting the pixels that are selected

Ellipse Select

Used to draw an ellipse or circle selection region

Zoom

This tool can be used to zoom in (left click), zoom out (right click), or zoom the whole canvas around a particular region (draw a rectangle).

Magic Wand

This tool is used to select areas of the active layer that are similar in colour.

Pan Tool

Paint Bucket

This tool is useful for filling in areas of similar color with a different colour.

Gradient

Paintbrush

This tool is selected by default when you start Paint.NET, and is useful for many kinds of freeform drawing.

Eraser

You may use this tool to erase areas of the image (it sets the transparency to 0).

Pencil

This tool allows you to edit the active layer pixel-by-pixel.

Colour Picker

You can use this tool to pick up a color from the active layer and set it as the current primary or secondary color.

Clone Stamp

This tool is useful for copying regions of pixels between layers, or within the same layer.

Recolour

This tool is useful for replacing one color with another.

Text

This tool is used for placing text on the image.

Line/Curve

This tool is used to draw straight and curved lines.

Rectangle

This tool is used to draw rectangles and squares.

 Rounded Rectangle

This is used to draw rounded rectangles and rounded squares.

Ellipse

This tool is used to draw ellipses and circles.

Freeform Shape

This tool is used to draw a shape with a freeform outline.

Graphic Terms

Animated GIF

An animated GIF is much like a flip book. Different images are displayed in a sequence, which give the appearance of movement

JPEG

A set of standards and a file format for the compression of digital colour images

Pixel

The smallest element of an image

BMP

Microsoft windows bitmap format. This is the only graphics format in which compression enlarges the file

Flip

 Flipping an object on one of it's axis. This produces one image that is alike the original

Video Card

A card which generates and outputs images to a display

Crop

To cut short

Mirror

An image as it would appear as viewed in a mirror, with right and left reversed. The end result is two pictures

Frames Per Second (FPS)
The unit for measuring the frame rate of a moving image

Frame
One of the continuous pictures on a strip of film

Morph
When the subject changes appearance. Either gradually, or instantaneously

(The Brain) Central Processing Unit (CPU)
The key component of a computer, which has the circuts that are necessary to interpret and execute program instructions

Dots Per Inch (DPI)
A way to measure the resolution of printed text and pictures. The more dots per inch - the higher the resolution

Resolution
The maximum amount of pixels that can be displayed on a monitor.

File Extension
A portion of the file's name, after the final point, which shows the kind of data stored in the file. Examples below


Compression
The reduction of the storage space required for data by changing it's format

Frame Buffer
A section of a video system where an image is stored, pixel by pixel. A frame buffer is also used to refresh a raster image

Colour Depth (Bits Per Pixel)
The number of bits of information stored in each  pixel of an image. If there are more bits, this means that more colours can be represented. A higher number of bits means that it will take much more of the computer's memory to store and display the image
