- 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

drives - 5) Portable Storage

3PC 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. -
4PC 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).
5PC CPU, memory, hard drive (cont.)
- C) Hard drive
- Sizes vary from 40 gigs up to one TB (1000 gigs)
- Dells 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.
6PC 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

computer? - Start Settings Control Panel Systems
- Basic Hard Disk support

82) 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.
93) 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?tagtnav - 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
103) 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)

113) 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
123) 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 Dont forget to format the memory card
after each use. - Recovery software
- Image Rescue Software
