1. Task 1

2.  Pixels are small dots on the
screen that makes the
image appear. The
resolution show how many
pixels by how many. The
higher the resolution is, the
more detailed the image is.
As you can see in my
example I have found the
first box shows the
resolution of 1 by 1 pixel
making just one big pixel
but as the resolution
doubles the letter R is
forming at 100 by 100 you
can see the letter as clear
as it was.

3.  Vector graphics are made
with points, lines, curves
and shapes. All of them join
up to produce images in
computer graphics.
 Raster graphic or an bitmap
has rectangle grid of
coloured pixels.

4.  Jpg is mostly used in
cameras or other capture
devices. JPEG reaches 10:1
compression with little
perceptible loss in image
quality
 Psd is an Adobe Photoshop
document. The file saves I
the images changes or add-
ons like
layers, text, transparency.
Psd can hold up to 30,000
and the size of 3 gb.

5.  Lossless compression
enables you to compress
data from keeping all of
the data together. When
compressed all of the
data is kept. This is done
through mathematical
formiler such as vectors.
 Lossy compression takes
some of the compressed
data and gets rid of it, it
tries to use the less amount
of that that it can. A
example of this is Jpeg.

6.  Image capture devices
(Cameras) take pictures or
images. The device will
capture what it see and
save it as an jpeg. Saving it
as a jpeg makes the images
from the device have less
quality but more file space
to take more images.

7.  Optimising is use to get rid
of unwanted files which
helps speed up the
computer. This would also
make more room for files
that seem necessary for
your computer.

8.  Storage management
handles the memory within
your files and hold spaces
for future files to come.
 Asset management takes
tasks and discussions about
an topic for example
ingestion, annotation, catal
oguing, storage, retrieval
and distribution of digital
assets
