		Such personal computers can also be linked together in a network, where each computer is connected to others, usually by wires or coaxial cables, permitting all to share resources such as printers, modems, and hard-disk storage devices.
		Although the development of digital computers is rooted in the abacus and early mechanical calculating devices, Charles Babbage is credited with the design of the first modern computer, the “analytical engine,” during the 1830s.
		First-generation computers were supplanted by the transistorized computers (see transistor) of the late 1950s and early 60s, second-generation machines that were smaller, used less power, and could perform a million operations per second.

	Computer storage density - Wikipedia, the free encyclopedia
		Computer storage density is a measure of the quantity of information bits that can be stored on a given length of track, area of surface, or in a given volume; of a computer storage medium.
		Surface density: The diskette will store 80 tracks of data at a spacing of 135 tracks per inch (5.05 tracks per millimeter) with the innermost track at approximately 10.5 millimeters radius and the outermost track is at approximately 25.5 millimeters radius.
		Also, storage densities computed for comparison of technologies usually ignore physical containment; that is, memory density is computed based upon the number of bits relative to the surface of the integrated circuit, rather than the surface of the encasement.

	Computer storage - Wikipedia, the free encyclopedia
		The terms "storage" refer to the parts of a digital computer that retain physical state (data) for some interval of time, possibly even after electrical power to the computer is turned off.
		Each type of storage is suited for different purposes, and most computers contain several types: primary, secondary, and volatile.
		In disk storage, these are the two primary access methods.

		Holographic data storage is an optical method of storage, wherein data is written as light patterns in three dimensions.
		In addition to high storage density, holographic data storage promises fast access times since laser beams can be moved rapidly without inertia.
		The biggest challenge for ‘holographic storage’ to gain mass acceptance is with respect to finding the right material for the recording medium—one that works and is inexpensive enough to produce commercially.

		Although the breakthrough is another opportunity for IBM to flex its storage muscles and kick sand at the R&D efforts of rivals (CI No 3,666), it will be greeted with quiet sighs of relief in many quarters of the storage business.
		One of the basic problems IBM seems to have solved in its latest demonstration is the tendency for the magnetic performance of individual particles in storage media or its "grains" to become unstable as density increases.
		This development will be "inconvenient" for the storage business, involving a move to radically different materials, but it would preserve the usefulness of most other storage technologies since the bigger grains will be magnetically more stable.
