  2. Buying a Desktop Personal Computer System • To buy a PC represents a major investment in both time and money. • You will use your computer for at least three years, perhaps even longer.

  3. Step one: Identify your needs • Where will I use my new PC? • You should consider purchasing a notebook {laptop} computer weighing five pounds or less? • For what purposes will I use my computer for example will you use your PC to prepare letters and reports? • How long will I keep this computer? http://www.tangle.com/view_video.php?viewkey=7336bbd7176faebc77e9

  4. Step two: Establish a budget • Ask yourself “how much you can realistically afford to pay for a computer”? • Prices of desktop personal computer’s, range from a few hundred to thousands of dollars.

  5. Step Three: Choose Software to Match your needs list. • Every computer must have software: including system software, and applications software. • Most PCs come with the system software already installed.

  6. Step Four: Select the HardwareComponents • Hardware: refers to all of the equipment that makes up a personal computer system, the system unit input devices, output devices, secondary storage devices, and all peripheral devices.

  7. The system unit • The system unit contains a microprocessor, main memory (RAM), and slots for installing a graphics board, sound board, modem or other peripherals. • Hard disk drives, and DVD drives are also housed in the system unit.

  8. PC Architecture • PC architecture: refers to the design and construction of the PC and its system unit, not all architectures are the same. • The architecture of an Apple Macintosh differs from that of an IBM or IBM-compatible PC, therefore software written for Apple may not work on IBM.

  9. Microprocessor • Selecting the right micro processor is extremely important. • Processing speed, typically is measured in gigahertz, would be the first consideration for the microprocessor.

  10. Main memory • Newer desktop PCs typically come with 512MB of RAM , or more. • Make certain the PC has sufficient Ram to run the software you will be using. • For example, if you will be working with newer larger and more complex applications, such as video and graphics editing watching movies or listening to music consider buying a PC with 2 gigabytes (GB) of RAM.

  11. Secondary storage • Start with a hard drive with 80GB. • If you’ll be storing many photo and tunes, move up to 160 GB. • A standard compact disc can store up to 750 MB of data, and certain DVDs provide even greater storage capacity.

  12. PORTS • External ports allow you it connect peripheral devices such as modems, printers, digital cameras, and mice. • Most PCs have at least one of the three basic types of ports: parallel, serial, and Universal Serial Bus (USB)

  13. Input Devices • Most keyboards and mouse operate similarly. • Some sellers will allow you to exchange the keyboards or mouse the comes with the computer for a different one of comparable value.

  14. Output Devices • Output devices produce output in either soft copy or hard copy form. • Monitors: slim, lightweight, flat screen liquid crystal display (LCD) monitors have virtually replaced the older and bulkier cathode ray tube (CRT) displays. • Printers: two popular types of printers are jet and laser. Both of these devices produce high quality output in color.

  15. Installing a desktop personal computer • Step one; unpack your computer system. • Locate all items • Keep them together • Be sure not to loose any important items in case you need to return the computer. • Step two: connect the components. • Locate the ports • Locate the important documentsand carefully follow the directions. • Follow the directions on how to put the computer together and installing the software. • Step three: boot the computer • After connecting all the devices, plug the surge protector into the wall outlet • Turn it on • Check and make sure everything is working correctly • Read all the helpful hints • Enjoy your computer.
