  6. You must do your homework!Second – Do the research! • Consumer Reports • PC magazine • PC World magazine • Smart Computing magazine • Web searches with Google • What about “How to Buy” books?

  7. Critical Decision #1Laptop or Desktop? • Laptop (+) Portable (+) Convenient (+) Uses much less space (-) Difficult to upgrade and expand (-) More expensive to repair (-) Less ergometric (-) Can be easily stolen (-) More expensive

  8. Critical Decision #1Laptop or Desktop? • Desktop (-) Stationary (-) Uses more space (+) Easier to upgrade and expand (+) Easier to repair (+) Better ergometics than laptops (+) Less likely to walk (+) Less expensive

  9. Critical Decision #1Laptop or Desktop? • Computing Power: Laptop vs. Desktop Laptops can have as much or more computing power than desktops. It’s not a matter of external size but rather what’s “under the hood.” The Bottom Line Strongly recommend the desktop for your basic home PC.

  10. Critical Decision #2 The Processor/CPU • The processor is the “brains” of your computer. • In general terms, the faster the processor speed, the faster your computer can work. • Processor speed is measured in gigahertz or billions of cycles per second (GHz). • Currently processors run at speeds of less than 1.0 to greater than 3.0 GHz.

  11. Critical Decision #2The Processor • Differences in processor speeds are not always noticeable. • Currently there are two major processor manufacturers: • Intel • Celeron (good) • Pentium (better) • AMD • Duron (good) • Athlon (better)

  12. Critical Decision #2The Processor The Bottom Line For most everyday users, an Intel Celeron or AMD Duron processor will work just fine. If you can afford the upgrade to the Intel Pentium or an AMD Athlon, do it.

  13. Critical Desion #3RAM • RAM is short for Random Access Memory • RAM is your PCs working memory – the place where information and instructions are temporarily placed while programs are opened and running. • When the computer is turned off data stored in RAM disappears. • RAM is measured in megabytes (MB) • Most PCs now have at least 128 MB of RAM

  14. Critical Decision #3RAM The Bottom Line RAM is probably the single most important factor in determining how well your computer performs. Generally speaking, the more RAM, the better. Consider 256 MB as a minimum. If you can upgrade to 512 MB RAM, do it.

  15. Critical Decision #4The Hard Drive • The hard drive (C:) is the PC’s central warehouse – the place where the startup files, operating system, and software programs are stored. • The capacity of the hard drive is measured in gigabytes (GB). • Most modern PCs have hard drives of 40 to 100 GBs

  16. Critical Decision #4The Hard Drive The bottom line Bigger is better Get at least 40 GB; more to give you room to grow with your computer

  17. Option #1Display Monitors • Monitors are prices by • Size – measured diagonally • Type • Box (CRT*) • Flat screen (CRT*) still a box but reduces glare & display distortion • Flat panel (LCD**) The Bottom Line “Seeing is believing!” (*Cathode ray tube) (**Liquid crystal display)

  18. Option #2Additional Storage Devices • The selections • Floppy disk • CD-ROM • DVD • CD-RW • Zip Drives • USB Memory Keys • Combination Drives The Bottom Line • Be sure to get at least the CD-ROM • Upgrade to a CD-RW if possible • Floppies will soon be obsolete • Consider memory keys

  19. Option #3Video Cards/Sound Cards • Video cards are the interface between the PC and the display monitor. • Sound cards interface between the PC and the audio hardware including speakers and microphones. • Consider a more advanced cards if you are using programs that feature sophisticated video or graphics or high quality sound reproduction. The Bottom Line The video card and sound card that comes standard with the PC is usually a high-end product with all the capabilities and features you will need.

  20. Option #4Multi-Media Hardware • Multi-media hardware lets your PC play music and video. Consider adding a DVD drive for watching movies. The Bottom Line At a minimum, you need a CD-ROM drive, a sound card and speakers.

  21. Option #5The Operating System • Current standard is Windows XP • XP comes in home and professional versions The Bottom Line For everyday users, the home version of XP will meet your needs.

  22. Option #6Productivity Software • Choose from various bundles for software like • Works Suite • Microsoft Office XP Small Business • Microsoft Office XP Professional Edition The Bottom Line Works Suite with MS Word is a good choice.

  23. Option #7Internet Access • You can connect to the Internet using dial-up, broadband (DSL or cable) or wireless connections. The Bottom Line Make sure your PC has a modem and a network interface card (NIC) so you can opt for a broadband connection.

  24. Option #8Peripheral Connections • Peripherals are external devices such as printers, scanners, digital cameras, etc. • Peripherals connect to your PC by • Serial/parallel ports • USB (universal serial ports) • Wireless connections The Bottom Line Plug-n-Play peripherals are quickly becoming the industry standard. Make sure your PC has enough USB ports in addition to the standard serial/parallel ports.

  25. Option #9Input Devices • Input devices allow you to give the computer instructions and enter data. The two main input devices are the mouse and keyboard The Bottom Line The mouse and keyboard sold as part of your PC package will meet your basic needs. To upgrade, select an optical mouse and an ergometric keyboard.

  26. Other considerations • Brand choice • Mom-n-Pop purchases • Warranties • Protection software with purchase • ISP with purchase • Obsolete so soon • Place of purchase: store or phone or online • Build your own
