Document Summary

Solid state vs. hard disk drives: ssds, resistant to physical shock, lower data access time (approx. 500 mb/s-3. 5 gb/s: expensive sh. 50/gb, capacities up to about 1 tb, hdds, sensitive to physical shock, higher data access time (approx. 10 ms: lower data transfer rates (approx. Inexpensive sh. 05/gb: capacities up to 10 tb. 256 of tlc flash storage: assume approx. 25 gb of writes per day (typically far less: 1000 write cycles means 256k gb (256 tb) of data before failure, 256k gb/25 gb per day=10k days=approx. Display technology: lcd & led, most modern displays use a liquid crystal display (lcd) panel and light. Better reproduction of colours, especially when viewed from angles: used in most contemporary displays. Input devices allow users to provide information to the computer: e. g. , keyboards, mice, trackpads, game controllers, webcams, microphones, output devices allow computers to communicate information to users, e. g. , displays, printers, speakers, hybrid devices facilitate both input and output.
