Document Summary
Cd-r (compact disk-recordable) used for recording only one: 3. Dvd :a cd style disk with extremely high capacity: 2. Dvd-r (dvd-recordable) is used for recording only one: 3. Dvd-rw, dvd-ram, dvd+rw are all reusable: 4. Dvds hold more data than cds do. Nonvolatile (retains data even when power is off) Usb flash drive: smart cards, pocket-size card with integrated circuits. Resembles a credit card but contains a microprocessor and memory chips. Online secondary storage (cloud storage): allow you to use the internet to back up your data. Tiny machines work at a molecular level to make nano circuit. Optical computing uses lasers and light, not electricity. Uses strands of synthetic dna to store data. Devices that translate data into a fonn the computer can process (into binary os and 1s). Includes: keyboards, pointing devices and source data-entry devices. Output hardware: devices that translate information processed by a computer into a form humans can understand (binary code => words, pics,)
