We have hard contains and floppy disks (soon making carriage to the CD-ROM), both of which usher out store or so quantity of data. In a disk train, a read/ frame promontory (usually a coil of wire) passes over a rotate disk, generating an electrical current, which defines a bit as either a 1 or a 0. There are limitations to this though, and that is that we agglomerate and make the head so small, and the tips and sectors so close, before the drive starts to suffer from interference from nearby tracks and sectors.
What other option do we have to store massive amount of data? We rear put on light. Light has its advantages. It is of a short wavelength, so we can place tracks very close together, and the size of the track we use is dependent only on one social function - the glossiness of the light we use. An optical medium typically involves some tell apart of laser, for laser light does not diver...If you need to get a full essay, order it on our website:
