A desktop computer, commonly known as a PC (although this term can also refer to a Macintosh computer) is a computer which is designed to be used in one fixed location, in contrast to portable computers such as laptops. Before microprocessors became as small as they are today, a desktop computer was really any computer which could fit on a desk at all! Now, when this term is used, it is generally to denote a certain type of computer casing. A desktop computer can actually come in a number of shapes and styles now, from the familiar tower shape to form factory models which can be hidden behind the monitor of the computer.
Strictly speaking, a desktop computer is one with horizontally oriented casing. The design is meant to save space, since the monitor can be put on top of the computer to make more room on a desk. These systems usually have a separate mouse, monitor and keyboard.
An all in one computer is one where the CPU and monitor are housed in a single casing. An example of this style would be the once ubiquitous iMac, preceded by the Kaypro II of the mid 1980s. All in one computers could be classed as semi-portables, since they can be unplugged and transported as a single piece generally (again, like the iMac).
Just like the laptops, the All-in-one desktop computer tends to suffer from a comparative lack of upgradeability because internal hardware is usually placed in the back part of the visual display unit. In the situation of the iMac line since the year 2002, the CPU as well as other internal hardware units are, more or less, glued permanently to the motherboard due to constraints of space.
Desktop computers have a number of advantages over laptops. One is that it is far easier and cheaper to replace hardware when needed, since these parts are much more standardized, which is not the case with most laptop computers. A desktop computer also features more room for expansion; a desktop computer typically has several PCI card expansion slots, compared to perhaps two on a laptop. These computers are also far easier to upgrade and repair; assembly and disassembly are far easier procedures and remains much the same regardless of brand.
A desktop computer also has the advantage of the user not having to be concerned about power management - it runs from wall current, so you can simply plug it in and go. Desktops also run cooler than a laptop, since there are more places for heat to escape. The microprocessors made for laptops are lower in the consumption of power and the generation of heat, but also offer less performance than do desktop processors. - 16747
