How do computer hard drives function?
A hard disk is a device that is used to store large amounts of data in a computer system. Hard disks differ from other memory because they are non-volatile; they retain the data even when they do not have power.
The data, which can be either just informational data, or executable programs, is written onto a spinning disk by making magnetic pulses very near the surface of the disk which make magnetized spots on the disk. The data is comprised of places which either are, or are not magnetized, yielding ones or zeros. The coils which make the magnetic field are on movable structures which "fly" above the disk, in that they are spring loaded to force them toward the spinning disk, but since actual contact would destroy both the coil and the disk, the structure is shaped like an airfoil (airplane wing), so that the relative wind from the spinning disk forces the coil structure just a small distance away from the disk.

- Finally the resulting sum is stored in the register R0
- The preceding add instruction combines a memory access operation with an ALU Operations. In some other type of computers, these two types of operations are performed by separate instructions for performance reasons.
- Load LOCA, R1 Add R1, R0 Transfers between the memory and the processor are started by sending the address of the memory location to be accessed to the memory unit and issuing the appropriate control signals. The data are then transferred to or from the memory.
