Design Compression
Reducing a file’s size/required storage space
Design Benefits of compression
Lower storage requirements on the server side, more responsive upload rates/less time to transfer files to the client side
Design Compression techniques
Lossy and lossless compression
Design Lossy compression
Removes some of the data when compressing, so compression rates are higher Only if the file format supports lossy compression
Design Lossless compression
Maintains all original data, lower compression rates
Design Types of site navigation sructures
Linear, hierarchal
Design Linear navigation structure
A structure where the user moves from one page to the next in a sequence
Design Hierarchal navigation structure
A structure where pages can be accessed dependant on the user’s position in the hierarchy
Design Wireframes

Design Wireframes must show…
Navigation links, text areas, media used with file format, position and types of hyperlinks
Design Benefits of wireframes
Used to show the client the design early-on, easy way to design user-interface
Design Low-fidelity prototypes
A quick design of the user-interface of a website, usually drawn on paper Benefit of it being low cost
Design File formats for audio files
WAV and MP3
Design Compression in WAV files
Almost always uncompressed Can sometimes use LCPM encoding for lossless compression
Design WAV file consistency
Consistent with the original sound
