Slide 1
These are ways to add connections and additional gizmos to your machine. These are the “big 3” right now.
Several different types of USB connectors. There are tons of adaptors available – check Big Lots!USB is used for just about everything now – data storage, keyboards and mice, audio recording, video recording. It’s cheap and ubiquitous.
Firewire has been popular for a long time for pro-level audio and video recording, camcorders, and hard drives. The hard drives are migrating to eSATA and USB, and consumer audio/video work has migrated to USB2.The big difference is that EACH firewire device has the full bandwidth available. The more USB gizmos you connect the less bandwidth each has available.
Has become VERY popular for use with hard drives. It’s cheaper and much faster than the previous bus (IDE/ATA/EIDE).
A cool thing.
Yet again, the same answer. You can always add additional busses to your machine with expansion cards.
No, not this kind! Computer pointers.
Different mice fit your hand differently. It really makes a difference!The one on the right has a built-in microphone and speaker.

Trackpads are handy, but many hate them. Check out the new ones that are multi-touch capable – pretty cool!
I’ve used a trackball for years – it takes up less desk space than a mouse, and is easy to use. There are a lot of different designs. It’s often tough for a lefty to find one that works for lefties, though!Most come with software that lets you define what the buttons do.
A keyboard like this looks weird, but is actually PHENOMALLY comfortable, and can help avoid carpal tunnel and other hand injuries. Notice the built-in trackball.
Yep, it’s really called the “pointy stick”. It’s a mouse substitute. I hate them! Used on laptops – I’ve not many people who actually like them, though they do exist!
Imagine guiding the pointer with your eyes, and clicking with a blink or wink. It’s doable 0 but experimental (and expensive).

No, not this kind!

Busses
Bus: Connection point to add stuff
USB
1.1 vs. 2.0
Firewire
400 vs. 800
SATA – “Serial ATA”. Cheaper, faster than ATA/IDE for hard drives
PATA (aka IDE/ATA) – internal drives
Characteristics
Hot Swappable
Easy Setup and Use
Newer **IS** backwards compatible with older
Firewire 800 can use Firewire 400 gizmo with an adaptor
Don’t forget to “eject”!
Prevent headaches and data loss
USB
Up to 127 Devices
1.1: 12 Mbits/sec
2.0:480 Mbits/sec
Male Type A
Male Type B
Micro Type
Female Type A
FireWire
FW400:400 Mbits/sec
FW800:
800 Mbits/sec
FW400
FW mini
SATA
150 MB/sec & 300 MB/sec
eSATA = external
Primarily used for Hard Drives
More SATA Cables
If Motherboard has a SATA port, and use this gizmo to make them externally accessible
Hmmm……..
Pop HD into port like Atari game cart
Also has card reader, USB ports
Connects to CPU via eSATA
Handy if have hard drives sitting around
External Enclosures
Box that connects to machine
YOU add a hard drive to it
Pay attention to the connection types
SATA – IDE/ATA – USB – FIREWIRE
INTERNAL vs. EXTERNAL
Examples
External Enclosures
Hard Drives
Add-on cards
Which to get?
Which to get?
Get what your computer has
Can add additional busses w/ expansion cards
Have to know what type of slots your machine has: PCI, PCI-X, PCI-E, etc.
Pointers
i.e. Pointing Devices
Mice
Makes a difference – especially for lefties
Trackpad
Multitouch?
Definition
Example
Video – scroll down
Youtube
Trackballs
Look for
- Connection type
- DPI
- customization
Ergonomic from Maltron
Pointy Stick
Eye Tracker
