SKM4263: Multimedia Internet  Overview of digital archiving  Examples of online digital storage  Advantages and disadvantages  Permanence!  Selecting online digital storage Source: ePortfolios for Learning blog entries on Digital Archive for Life by Dr. Helen Barrett  Internet/hosted storage  Use a service provider to store their data online  Avoid storing data locally on physical disks  Used as  Add-on method for existing data storage solutions  Increasing numbers of people → faster internet speeds  Easyaccess to documents, images and other media  Documents, files etc. can be made available anytime  As long as user is connected to the internet! http://www.youtube.com/watch?v=tAUuY0Yld0E Examples of ODS? Pictures?
