Trends & Contemporary Technologies Communications Technologies Storage Technologies Processing Technologies Display Technologies

Communications Technologies Buses –USB 2 –Firewire Wireless –WiFi –Bluetooth

Storage Technologies Magnetic Technologies –Tapes, Floppy disc drives & Hard Disc drives Optical Technologies –CD-ROMs, DVDs Holographic Technologies –Holographic Versatile Disc

Holographic Versatile Disc This technology records data in layers right through the full depth of the medium and not just on the surface as with CD and DVD technology Advantages –Very fast access speed as millions of bits can be written or read in parallel in a single operation –Very high storage capacity ( terrabytes) making it suitable for staorage of multimedia

Processing Technologies Becoming smaller, faster & cheaper Some now are multi-processor machines –Have processors for individual tasks such as video compression & processing.

Display Technologies Flexible Displays –Roll it up and carry it away Virtual 3D –Simulates 3D by providing separate images for each eye. Some need special glasses Real 3D –Projects a moving image in to space.

Converging Contemporary Technologies Smartphone: –merging technologies of a mobile phone and a laptop. Pocket PC: –merging technologies of a laptop, mobile phone and desktop operating system and application software.
