  1. Digital Hardware Essex Photo Club April 25, 2007

  2. Topic To Be Covered • 1) PC – CPU, memory, hard drive • 2) Connections - Parallel, Serial, USB (1.0 and 2.0), Firewire, and Bluetooth • 3) Camera memory – memory types, how to transfer • 4) Saving data – CDs, DVDs, and External Hard drives • 5) Portable Storage • 6) Other hardware – Monitors, Thumb Drives, Wacom • 7) Web Site Links

  3. PC – CPU, memory, hard drive • A) CPU (central processing unit ), The Brains of the computer Two main Brands Intel & AMD Intel Centrino (Mobile) Pentium Celeron (Lower end) AMD Athlon Turion (Modile) Sempron (Lower end) Single-Core vs. Dual-Core A processor core executes the instructions that enable your PC to operate at a given speed. Single-core processors provide adequate power for activities like emailing and working with spreadsheets. Additional cores give you more capacity, working together to move operations along at a quicker pace. Dual-core processors place two cores on a single die, giving you more power to multitask; for example, you can run virus protection, burn MP3s and play graphic-intensive 3D games simultaneously at super-fast speeds.

  4. PC – CPU, memory, hard drive (cont.) • B) Memory Common types of memory technology today include: a) DDR2 (double data rate, second generation) b) SDRAM and DDR (double data rate, first generation) c) SDR (single data rate) Memory is in pairs. So if you wanted to add 1 gig of memory to your computer you would need two 512 chips. Most modern computers will go up to 4 gigs max (Dell price 512 mb standard ($359) 1 GB = $60, 2 GB = $190, 4 GB = $460) (You can get the memory cheaper else where. 4GB at NewEgg.com for $359).

  5. PC – CPU, memory, hard drive (cont.) • C) Hard drive Sizes vary from 40 gigs up to one TB (1000 gigs) Dell’s computer for $359 included a 160 GB hard drive. (Upgrades: 250 GB = $40, 320 GB = $90, 500 GB = 180) (Try and get as large of a hard drive as you can afford. You can have more than one hard drive. D) PC Recommendations Fast CPU (Intel® Pentium® 4, Intel Centrino®, Intel Xeon®, or Intel Core™ Duo ) (This will add anywhere from $400 to $1000 to the total cost.) Plenty of RAM at least 1 GB minimum (You can add more later) Large and fast hard drive (Minimum 160 GB at 7200 RPM) The Dell PC for $359 is for the Sempron CPU. This is a low end CPU.

  6. PC Recommendations Photoshop CS3 requirements • Windows • Intel® Pentium® 4, Intel Centrino®, Intel Xeon®, or Intel Core™ Duo (or compatible) processor • Microsoft® Windows® XP with Service Pack 2 or Windows Vista™ Home Premium, Business, Ultimate, or Enterprise (certified for 32-bit editions) • 512MB of RAM ( You need much more that 512. I would look at 2 GB or better) • 64MB of video RAM • 1GB of available hard-disk space (additional free space required during installation) • 1,024x768 monitor resolution with 16-bit video card • Macintosh • PowerPC® G4 or G5 or multicore Intel processor • Mac OS X v.10.4.8 • 512MB of RAM ( You need much more that 512. I would look at 2 GB or better) • 64MB of video RAM • 2GB of available hard-disk space (additional free space required during installation) • 1,024x768 monitor resolution with 16-bit video card

  7. Basic PC information • How do you check how much space is on your hard drive? • My Computer > Left Click on C: > Right Click > Click on Properties • How do you check how much memory is in your computer? • Start > Settings > Control Panel > Systems • Basic Hard Disk support; • Disk Clean Up • My Computer > Left Click on C: > Right Click > Click on Properties > Disk Clean Up • Disk Defrag • My Computer > Left Click on C: > Right Click > Click on Properties > Tools

  8. 2) Connections - Parallel, Serial, USB, Firewire, and Bluetooth Parallel – use to be used for printers and scanners. Not used very much anymore. Serial – use to be used for all kinds of equipment, modems, external drives, etc. Not used very much anymore. USB 1.0 - Short for Universal Serial Bus, Supports data transfer rates of 12 Mbps (megabits per second) USB 2.0 - supports data rates up to 480Mbps Bluetooth – Short-range radio, transfer rates are slow (between 17 - 25Kbps (kilobits per second) Firewire – aka - IEEE 1394 transfer rates up to 800 Mbps, can support up to 63 external devices. This is the ideal device for transferring high levels of data.

  9. 3) Camera memory – Memory types, how to transfer There are many different types of memory. (See url below) http://reviews.cnet.com/Digital_cameras/4520-7603_7-5023995-4.html?tag=tnav CompactFlash is among the most common. Memory Speeds: They use the same rating system used by the CD-ROM industry, where data transfer rate of 1X equals 150 kilobytes (KB) per second. The higher the speed rating, the faster your camera will be able to write images to the memory card

  10. 3) Camera memory – Memory types, how to transfer (cont.) There are two main brands: Lexar and Scandisk Lexar has three versions: CompactFlash Card is 4X Platinum Card is 40X = 6,000 KB or 6 MB per second Professional CompactFlash is 80X = 12,000 KG or 12 MB per second Sandisk has three version: CompactFlash UltraII (9 MB) Extreeme (20MB/sec) Popular Photography, April 2005, Editorial: Card Sharks http://www.popphoto.com/article.asp?section_id=3&article_id=1351&page_number=1

  11. 3) Camera memory – Memory types, how to transfer (cont.) How to transfer the photos from the memory card to the computer 1) Use the camera cable and camera software.(This is the slowest way) 2) Use a card reader. This is an additional hardware unit that is external or internal. External is a USB connection and cost under $20. Internal is like a floppy drive. Using the camera for 2 gigs could take up to an hour. Using the External Card Reader would take 15 minutes

  12. 3) Camera memory – Memory types, how to transfer (cont.) Memory Card Readers: Caution: When looking at an external card reader, make sure you get the correct reader for your memory. They sell card readers for CompactFlash, Secure Digital/MultiMediaCard, SmartMedia, and Memory Stick Note: Don’t forget to format the memory card after each use.

  14. 4) Saving data – CDs, DVDs and External Hard drives (cont.) • CD or DVD can be internal units, external or portable • Internal are mounted in your computer, cost any where from $40 to $150 • Samsung 18X Double-Layer (DVD/CD) $49 (Best Buy) • External use the USB or Firewire, cost anywhere from under $70 to $150 • Samsung 18X Double-Layer (DVD/CD) $79 (Best Buy)

  15. 4) Saving data – CDs, DVDs and External Hard drives (cont.) • Notes about CD/DVD: • Don’t write on them with ballpoint pens. Use markers for CD/DVD • Don’t put labels on CD/DVD • Buy good brand CD/DVD. (See PDF file) • Try to keep CD/DVDs out of extreme temperatures. (Don’t keep them in your car.) • Protect the non label side of the CD/DVDs • There are debates as to how long the data will last

  16. 4) Saving data – CDs, DVDs and Hard drives (cont.) • Additional hard drives • They can be internal or external • Internal: • You can add an internal hard drive to most computers (Could be complicated) • A 60 GB drive would cost around $88, a 750 GB would cost around $385

  18. 5) Portable Storage • There are Two types of portable storage devices: • CD/DVD burner • Portable Hard Drive • CD/DVD burners Portable units that have slots for the memory card and let you transfer from the memory to a CD or DVD. http://www.disqworks.com/en/digimagicportable.html They are small, light, cheep, but they are slow and some don’t have a way to tell if your images were transferred.

  19. 5) Portable Storage (cont.) • Portable Hard Drives Portable units that have slots for the memory card and let you transfer from the memory to a hard drive. Small, light and most have screens to view the photos, but they are costly and the screens are not good iPod 80 GB ($400) http://www.bestbuy.com/site/olspage.jsp?skuId=8046072&type=product&productCategoryId=pcmcat63300050028&id=1158104003252 Epson p-500 80 GB ($700) http://www.epson.com/cgi-bin/Store/consumer/consDetail.jsp?BV_UseBVCookie=yes&oid=63061068

  20. Portable Storage (cont.) Pros and Cons iPod Pro Small, cheap and very popular Con Need adaptors, Transfer of files are slow, file transfers are a major drain on the battery, the iPod only supports Jpeg for viewing. Epson P-5000 Pro Easy to use, supports all file types, nice screen, supports SD and CF Con Adaptors needed for other memory cards, the unit does not come with a protective case. A little weak as a multimedia player.
