Contents. Hard disk drive failure. A head crash, one type of disk failure. The platters should normally be smooth in modern drives, and a head crash results in partial to total data loss, as well as irreversible damage to the platters and heads. Particles may also be liberated during this process, making the insides of the drive not clean ...

The state is a point on the surface of the sphere, partway between the poles, and . A quantum computer is a computer that exploits quantum mechanical phenomena. On small scales, physical matter exhibits properties of both particles and waves, and quantum computing leverages this behavior using specialized hardware.
Crash (computing) A kernel panic displayed on an iMac. This is the most common form of an operating system failure in Unix-like systems. In computing, a crash, or system crash, occurs when a computer program such as a software application or an operating system stops functioning properly and exits.
