Are you Looking for a New Desktop Computer?
A desktop computer is a personal computer (PC) in a form intended for regular use in one single location, compared to a mobile laptop or portable computer. Before the wide spread of microprocessors a computer that could fit on a desk was thought to be small. Today the word desktop usually indicates a particular style of computer case. Desktop computers come in a variety of forms ranging from large vertical tower cases to small form factor models that can be tucked behind an LCD screen. In this sense, the term ‘desktop‘ refers specifically to a horizontally-oriented case. Most modern desktop computers have separate screens, keyboards and mice. A specialized form of desktop case is used for home theater PC systems, giving the user front-panel mounted controls for audio and video.
Pro Tip: Carelessly-arranged computer screens and keyboards can lead to ergonomics problems such as eyestrain and repetitive strain injuries while using a keyboard for long periods. The height of a standard desktop is not recommended for keyboard use, and stacking the monitor on the case aggravates posture problems.
All-in-One computers are desktop computers that combine the monitor into the same case as the CPU. Some older 8-bit computers, such as the Commodore PET 2001 or Kaypro II, fit into this category. All-in-One PCs are typically more portable than other desktop PCs and many have built-in carrying handles attached to the case. They can simply be unplugged and relocated to a new location.
Just like their portable counterparts laptops, All-in-One desktop computers are defined by a comparable lack of ability to upgrade or customize the hardware, as internal hardware is often placed in the back of the screen or monitor. Furthermore, the all-in-one computers CPU and other internal hardware units are usually permanently glued to the motherboard due to space constraints.
Desktops have a few advantages over laptops one being that the spare parts and extensions tend to be graded, resulting in lower prices and greater availability. An example of this is the form factor of the motherboard being standardized, like the ATX. Desktops have several standardized expansion slots, like PCI or PCI express, while laptops tend to only have one mini PCI slot and one PC card slot. This means that a desktop can be customized and upgraded to a greater amplitude than their portable counterparts laptops.
Pro Tip: Procedures for disassembly of desktops tend to be simple and standardized to a great extent.
Another advantage of desktop computers is that the power consumption is not as critical as in laptop computers because the desktop is powered from the wall socket. Desktop computers also have more internal space for heat to escape.
