Information systems hardware data is processed and stored in a computer system through the presence or absence of electronic or magnetic signals in the computer's circuitry the principal characteristic of a computer generation is the fundamental technology employed to build computer. Magnetic liquid technology when a magnetic field is applied to a ferrofluid, the magnetic moments of the particles orient along the field lines almost instantly to lubricant vapors in the computer industry and to various adhesives in the speaker industry. A training programme understanding computers: an overview for records and archives staff international council on archives international records management trust describing the concepts associated with computer technology, this module explains. The key difference between optical storage media, such as cds and dvds, and magnetic storage media, such as hard drives and old-fashioned floppy disks, is in how computers read. Magnetic information is stored as 'bits' on the hard disc of a computer, or on magnetic tape used for backing up computers these bits correspond to small, uniformly magnetized regions 'written' into the magnetic medium by an applied field which defines the orientation of the magnetization.
