	Howstuffworks "What are the different types of computers?"
		While the term computer can apply to virtually any device that has a microprocessor in it, most people think of a computer as a device that receives input from the user through a mouse or keyboard, processes it in some fashion and displays the result on a screen.
		Laptop - Also called notebooks, laptops are portable computers that integrate the display, keyboard, a pointing device or trackball, processor, memory and hard drive all in a battery-operated package slightly larger than an average hardcover book.
		Although some supercomputers are single computer systems, most are comprised of multiple high performance computers working in parallel as a single system.

	Mainframe computer - Wikipedia, the free encyclopedia
		Mainframes (often colloquially referred to as Big Iron) are computers used mainly by government institutions and large companies for mission critical applications, typically bulk data processing such as census, industry/consumer statistics, ERP, and financial transaction processing.
		Modern mainframe computers have abilities not so much defined by their performance capabilities as by their high-quality internal engineering and resulting proven reliability, high-quality technical support, top-notch security, and strict backward compatibility for older software.
		Mainframes tend to have numerous ancillary service processors assisting their main central processors (for cryptographic support, I/O handling, monitoring, memory handling, etc.) so that the actual "processor count" is much higher than would otherwise be obvious.

	[No title]
		Mainframes (often colloquially referred to as "big iron") are large, powerful, and expensive computers used mainly by large companies for bulk data processing (such as bank transaction processing).
		Mainframe computers' abilities are not so much defined by their CPU speed as by their massive internal memory, large, high-capacity external storage, fast high-throughput I/O, high-quality internal engineering and resulting proven reliability, and expensive but high-quality technical support.
		Another factor currently increasing mainframe use is the development of the Linux operating system, which is capable of running on many mainframe systems, either directly or, more commonly, in a virtual machine.

		Mainframes (often colloquially referred to as big iron) are large and "expensive" computers used mainly by government institutions and large companies for mission critical applications, typically bulk data processing such as censuses, industry/consumer statistics, ERP, and financial transaction processing.
		Modern mainframe computers have abilities not so much defined by their performance capabilities as by their high-quality internal engineering and resulting proven reliability, "expensive" but high-quality technical support, top-notch security, and strict backward compatibility for older software.
		Nearly all mainframes have the ability to run (or "host") multiple operating systems and thereby operate not as a single computer but as a number of "virtual machines." In this role, a single mainframe can replace dozens or even hundreds of smaller servers, reducing management and administrative costs while providing greatly improved scalability and reliability.

		After the emergence of smaller "{minicomputer}" designs in the early 1970s, the traditional {big iron} machines were described as "mainframe computers" and eventually just as mainframes.
		It has been common wisdom among hackers since the late 1980s that the mainframe architectural tradition is essentially dead (outside of the tiny market for {number crunching} {supercomputer}s (see {Cray})), having been swamped by the recent huge advances in {integrated circuit} technology and low-cost personal computing.
		Supporters claim that mainframes still house 90% of the data major businesses rely on for mission-critical applications, attributing this to their superior performance, reliability, scalability, and security compared to microprocessors.

	Computer training - computer science degrees and computer courses
		Computer Science or Information Technology is the fastest growing career field in the United States.
		Computers are used in car engines, microwave ovens, watches, telephones, mainframe computers in government and industry, and supercomputers expanding the frontiers of science and technology.
		If your passion is technology or computers then a computer science degree from a computer training school is the only career move you will need to make.

		The term during the early 1970s with the introduction of smaller, less complex computers such as the DEC PDP series, which became known as minicomputers or just minis.
		IBM's dominance grew out of their development of the 360 series mainframes; this basic architecture has continued to evolve into their current zSeries mainframes which is arguably the only mainframe architecture still existent that dates from this early period.
