desktop computersdesktop computersA desktop computer is an electronic machine computer that converts raw data into meaningful information, made for use on a desk in an office or home and is distinguished from portable computers such as laptops or PDAs. Desktop computers are also known as microcomputers. There are four types of desktop computers: home computers, or personal computers; workstations, Internet servers, and special communications computers. Desktops are currently the most affordable computers and ubiquitous in businesses, schools, and households; they are used for performing office tasks, organizing digital photos, video editing, and Internet access. Nearly all desktop computers are modular, with components that can easily be replaced or upgraded. Desktop computers come in a variety of case styles ranging from large vertical towers to small form factor models that can be tucked behind an LCD monitor. desktop computers Hardware An exploded view of a modern desktop computer: Display Motherboard CPU (Microprocessor) Primary storage (RAM) Expansion cards Power supply Optical disc drive (ODD) Secondary storage (HDD) Keyboard Mouse The hardware in a desktop computer is modular, making it easy for someone with intermediate knowledge of a computer to modify one. Desktop computers are generally more affordable than notebook computers. This is because no extra effort is needed to miniaturize the components, nor to find design solutions to the thermal management problems that arise from the use of components that emit heat in a compact space. [edit] Components Fan - cools the computer. These are present on most computers. There are often multiple, one to cool the processor(see below), one in the power supply, and possibly additional ones for the graphics card and general cooling. Motherboard (a.k.a. mainboard) - links all of the components together and routes data. HDD (hard disk drive) - location where all information can be stored even when power is off. ODD (optical disc drive) - reads most or all types of CDs and/or DVDs. Processor - The main brain of the computer. CPU Cooler - cools the processing unit. Typically a fan combined with a heatsink. RAM - short-term data storage, volatile (data is erased when the computer is powered off) Graphics card - codes video output and delivers to monitor. Physics card - performs physics computations in some modern games. Sound card - codes sound output and delivers to speakers. Speakers - deliver sound. Modem - used to access data via a telephone line (dial-up connection). Used to access BBS and the Internet. Network card - allows the computer to be linked to a computer network where it can communicate with other computers. Also used as a means of accessing the Internet via a broadband connection. Computer PSU (power supply unit) - A device that provides power to the rest of the computer parts. FDD (floppy disk drive) - Reads and Writes floppy disks. Although largely supplanted by CDs and Flash Drives, is still common on many systems, and may be required during set-up on certain operating systems. computer liquidator computer liquidator buy computer Anna Kournikova Most current mobile phones connect to a cellular network of base stations which is in turn interconnected to the public switched telephone network national computer liquidation national computer liquidation cheap computer Brooke Burke Open-box, returned and/or repaired electronics of all kinds are frequently sold as refurbished, almost always with a guarantee of functionality and at a small discount computer liquidator computer liquidator computer laptops Angie Harmon monitor disposal is hard computer liquidators computer liquidators computer monitors Ashley Judd Motivations for purchase include conserving natural resources and protecting the environment, and may form part of a simple living plan network liquidators network liquidators computer store Cameron Diaz Public policy analyst James V computer liquidator computer liquidator desktop computers Angelina Jolie Modern von Neumann computers display some traits of the Harvard architecture in their designs, such as in CPU caches computer liquidator computer liquidator laptop computer Antonella Barba Most of them carry a 30 day store warranty and 90 days with manufacturer a z computer liquidators a z computer liquidators laptop computers Adriana Lima Mobile telephone use in etiquette is an important matter of social discourtesy, phones ringing during funerals, weddings, in toilets, cinemas, and plays liquidator computer liquidator computer liquidation Brittany Murphy Notebook and notepad are laptops liquidation computer liquidation computer liquidators Beyonce Knowles Nearly all desktop computers are modular, with components that can easily be replaced or upgraded computer liquidation computer liquidation recycle Amy Smart Modern computers are based on comparatively tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space computer liquidation computer liquidation recycling Ali Larter Modern computers are based on comparatively tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space network liquidators network liquidators recycling center Carey Lowell Purchasing used items for reuse prevents them from becoming waste and saves costly production of equivalent new goods liquidators computer liquidators computer recycling centers Brittany Murphy Often, antiques such as furniture are refurbished to bring back their original luster by applying new paint or wood stain, fixing loose joints with glue or nails, and cleaning or replacing hardware such as drawer pulls national computer liquidator national computer liquidator used computer Brooke Shields Others, however, have calculated through life cycle assessment that producing recycled paper uses less energy and water than harvesting, pulping, processing, and transporting virgin trees Nortel liquidation Nortel liquidation used computers Carre Otis Recyclable electronic waste is sometimes further categorized as a commodity while e-waste which can not be reused is distinguished as waste used computer liquidation used computer liquidation used laptop Celebrity Recycling is a key concept of modern waste management and is the third component of the waste hierarchy national computer liquidators national computer liquidators used laptops Brooke Shields Personal computers in various forms are icons of the Information Age and are what most people think of as "a computer"; however, the most common form of computer in use today is the embedded computer phone liquidation phone liquidation used notebooks Catherine Bell Recyclable materials, also called recyclables , may originate from a wide range of sources including the home and industry Cisco tigers Cisco tigers computer notebooks Ali Landry Mobile telephone use in etiquette is an important matter of social discourtesy, phones ringing during funerals, weddings, in toilets, cinemas, and plays used computer liquidators used computer liquidators liquidation Celebrity Pic Recycling is the reprocessing of materials into new products |
