ASSIGNMENT 4 WEEK 1 - STORAGE DEVICES Describe the main working features of ONE of the following storage devices. Hard disk drive Optical storage Flash memory Include any relevant diagrams that help explain your answer. Optical Storage The optical storage device that most of us are familiar with is the compact disc (CD). A CD can store huge amounts of digital information (783 MB) on a very small surface that is incredibly inexpensive to manufacture. The design that makes this possible is

(the over enrichment of aquatic ecosystems with nutrients leading to algal blooms and anoxic events) is a persistent condition of surface waters and a widespread environmental problem (Carpenter‚ 2005). The main cause is excessive loading into the system of phosphorus and nitrogen‚ resulting in high algal biomass‚ dominance by cyanobacteria‚ and loss of macrophytes (Dixit‚ 2005). When the nutrient concentrations rise to extremely high levels‚ eutrophication occurs. There are two stages‚ which begin

Optical illusions have been around for centuries‚ teaching us that you shouldn’t fully trust your senses due to that we can easily be tricked. However‚ optical illusions can help us learn how easy it is to trick our brain to see an object that seems real but is really not. An example of a well-known visual illusion would be the “Ames Room”.
