Personal and desktop microcomputers (PC) have become indispensable office equipment in many firms. These powerful machines have revolutionized business computing and information management by their variety of applications. These PCs are equipped with internal memory and disk capacity through the workings of the microprocessor chip, which determines the varying degrees of sophistication, speed and applicability of PCs. These PCs usually have disk drives through which data is stored in floppy diskettes; hard disks and some have magnetic tape cartridges to provide back-up copies for security purposes. The basic PC would have a monitor, which is usually colour but can be monochrome, and it is often connected to a printer, of the dot matrix, inkjet or laser-type. The PC can also be attached to a modem to facilitate inter-PC communication and to allow downloading of data.
Within a desktop computer box there many components that make up a microcomputer. In this essay I will describe the major components of a microcomputer. The individual function of each component will be described, and how they integrate together to form a microcomputer. The main hardware com

How do computers Work http://www. All of the component parts plug or clip into the motherboard, which provides all the interconnections between all the components. The display is usually considered to include the screen or projection surface and the device that produces the information on the screen. A desktop computer typically comes in several units that are connected together during installation: (1) the main unit with processor, which can be in a micro tower or minitower designed to fit under the desk or in a unit that goes on top of the desk, (2) the display monitor, (3) and input devices - usually a keyboard and a mouse. It is measured in kilobytes (thousands of bytes of storage).
Storage
Almost all PCs have a flexible or "floppy" diskette drive that uses small, square plastic diskettes to store data.
Communication Devices
Modems enable a computer to exchange data, information, and instructions with another computer. Modems and Ethernet cards are the most common communication devices.
Microprocessor
One of the most important advancements to occur during this century was the invention of the microprocessor. Different configurations are available which determine the speed and reliability of the system. Other direct entry mechanisms are optical laser scanners, and voice-recognition devices capable of understanding simple verbal commands. While the diskettes that go into a floppy drive can be taken in and out, the hard drive generally has no removable parts.
