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
