The desktop computer is the most commonly used of the IT Services St. Louis personal computers and is also the most versatile. You are able to do a lot more with a desktop PC than you can with a laptop computer. They are also much easier to upgrade than laptops. It does sound like a laptop is a wise idea but that is not always the case; it depends to a large extent what you will be using your computer for. A desktop computer is a personal computer (PC) in a form intended for regular use at a single location, as opposed to a mobile laptop or portable computer. Prior to the wide spread of microprocessors, a computer that could fit on a desk was considered quite small. Today the phrase usually indicates a particular style of computer case. Desktop computers come in a variety of styles, ranging from large vertical tower cases to small form factor models that can be tucked behind or sit under an LCD monitor.
In this sense, the term ‘desktop’ refers specifically to a vertical case. Most modern desktop PCs have separate screens and keyboards. A specialized form of desktop case is used for home theatre systems, having front-panel mounted controls for audio and video. One of the problems all-in-one desktop PCs tend to suffer from is a comparative lack of upgradeability or hardware customization, as internal hardware is often placed in the back of the visual display unit. (similar problem to laptop computers) Desktop style personal computer with several common peripherals (Monitor, keyboard, mouse, speakers, microphone and a printer)Desktops have the advantage over laptops with the spare parts and extensions being standardized, resulting in lower prices and greater availability. For example, the form factor of the motherboard is standardized.
Desktop computers have several standardized expansion slots, while laptops only tend to have one mini PCI slot and one PC card slot (or ExpressCard slot). This means that a desktop can be customized and upgraded to a greater extent than laptops. This tends not to be the case for laptops, though adding or replacing some parts, like the optical drive, rechargeable battery, hard disk, and adding an extra memory module is often quite simple. One of the other advantages of the desktop computer is that power consumption is not as critical as in a laptop computer because the desktop is powered from the wall socket.
Desktops also provide more space for heat to escape. The two large microprocessor manufacturers Intel and AMD develop special CPUs for mobile personal computers (i.e. laptops) that consume less power and lower heat, but with lower performance levels. Health Effects of Desktop PCs Badly placed computer screens and keyboard can lead to ergonomics problems such as eyestrain and repetitive strain injuries while using a keyboard with a desktop computer for long periods. The height of a standard desktop is not recommended for keyboard use, and stacking the monitor on the case can also aggravate ones posture problems.
