Compression reduces file sizes and allows for faster transfer over the internet. Image capture devices range from cameras to scanners, with cameras recording still images and videos and scanners optically scanning objects. Optimising changes game and video settings to improve performance and prevent overheating. Storage saves documents to external devices like USBs, hard drives, with file size depending on type - videos and movies are usually larger than a gigabyte.

1. Task 1
Compression
Compression or data compression is used to reduce the file size of one or more files and will then
take up a smaller amount of disk space, compared to an uncompressed version of the file.
Compressed files can also be faster to send over the internet.
Image Capture Devices
Image capture devices range from cameras to scanners, cameras are devices that records images
and can be saved directly, it can take videos/moving images and pictures. A scanner is a device that
optically scans images, work and other objects placed within it.

3 7.1" x 4.7" 10.6" x 7.1"
4 8.2" x 5.4" 12.2" x 8.2"
5 9.1" x 6.1" 13.7" x 9.1"

8 11.5" x 7.7" 17.3" x 11.5"
12 14.1" x 9.4" 21.2" x 14.1"
16 16.3" x 10.9" 24.5" x 16.3"
22 19.1" x 12.8" 28.7" x 19.1"
The print size calculations above assumed that the camera's aspect ratio, or ratio of longest to
shortest dimension, is the standard 3:2 used for 35 mm cameras. In fact, most compact cameras,
monitors and TV screens have a 4:3 aspect ratio, while most digital SLR cameras are 3:2. Many other
types exist though: some high end film equipment even use a 1:1 square image, and DVD movies are
an elongated 16:9 ratio.
This means that if your camera uses a 4:3 aspect ratio, but you need a 4 x 6 inch (3:2) print, then
some of your megapixels will be wasted (11%). This should be considered if your camera has a
different ratio than the desired print dimensions.

2. Optimising
Optimising is changing the setting within a video or a game, changing
the level of graphics suitable for the computers spec and changing the
quality of what is on the screen.
By adjusting in game settings of a game can make it smoother and will
increase frames per second (FPS).
By playing a game with settings that your computer spec cannot run it
can over heat quickly and also crash your computer.

Storage and Asset Management
Storage is saving a document onto an external storage device, documents which are 3mb will take
3mb of disk space on the storage device. Larger files like videos and movies will take up a lot more
disk space and are usually larger than a gigabyte
Files, images, videos and documents can be transferred and stored on a USB, internal hard drive or
external hard drive.
USB’s can hold up to; 16gb on a small device
External and internal hard drives can carry up to 2tb
Measurements of bytes; kb (kilobyte), mb (megabyte) and gb (gigabyte)
There are 1024kb’s in 1mb and 1024mb’s in 1gb
