A programmable machine that responds to specified instructions and can execute a list of instructions known as a program. Today’s computers are electronic and digital-with wires, transistors, and circuits comprising the hardware and instructions and data comprising the software. Computers generally have these hardware components: (1) memory, allowing a computer to store data and programs, at least temporarily; (2) mass storage devices, allowing a computer to store and retain large amounts of data on the disk drives and tape drives; (3) input devices such as keyboards and a mouse, which act as conduits through which data are entered into a computer; (4) output devices, such as display screens and printers, that let users see what the computer has performed; and (5) a CPU or central processing unit, the primary component that executes the commands or instructions. On a humorous note, in a New Scientist article, futurologist Ray Kurzwell said that although a $1,000 personal computer in 2005 has about the computing power equivalent to that of an insect brain, if development advances continue at the same rate into the future, within 15 years a $1,000 personal computer should have the computing power equivalent to that of a human brain.
The chassis also contains slots for expansion boards. If you want to insert more boards than there are slots, you will need an expansion chassis, which provides additional slots. There are two basic flavors of chassis designsdesktop models and tower modelsbut there are many variations on these two basic types. Then come the portable computers that are computers small enough to carry. Portable computers include notebook and subnotebook computers, hand-held computers, palmtops, and PDAs. The term refers to a computer in which the power supply, motherboard, and mass storage devices are stacked on top of each other in a cabinet. This is in contrast to desktop models, in which these components are housed in a more compact box. The main advantage of tower models is that there are fewer space constraints, which makes installation of additional storage devices easier. A computer designed to fit comfortably on top of a desk, typically with the monitor sitting on top of the computer.

In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs. But supercomputers can execute a single program faster than a mainframe. The distinction between small mainframes and minicomputers is vague, depending really on how the manufacturer wants to market its machines. It is a midsize computer. In the past decade, the distinction between large minicomputers and small mainframes has blurred, however, as has the distinction between small minicomputers and workstations. But in general, a minicomputer is a multiprocessing system capable of supporting from up to 200 users simultaneously. It is a type of computer used for engineering applications (CAD/CAM), desktop publishing, software development, and other types of applications that require a moderate amount of computing power and relatively high quality graphics capabilities. Workstations generally come with a large, high-resolution graphics screen, at large amount of RAM, built-in network support, and a graphical user interface. Most workstations also have a mass storage device such as a disk drive, but a special type of workstation, called a diskless workstation, comes without a disk drive.
