11. Connecting Peripheral internal vs. external serial vs. parallel

12. Internal Bus Types parallel communications IDE (Integrated Drive Electronics) Hard drives, CD-ROM 16-bit parallel PCI (Peripheral Component Interconnection) network interface cards, video graphic adapters, etc. 32 or 64 bit parallel

13. Internal Bus Types, cont’d. PCMCIA (Personal Computer Memory Card International Association) laptop expansion cards 16 bits parallel newer CardBus supports 32 bits SCSI (Small Computer System Interface) several generations

14. External Serial Bus Types RS-232 PS/2 mouse and keyboard USB Firewire

15. Universal Serial Bus up to 6 Mbps; 2.0 -- 480 Mbps! two types of connectors “A”-- upstream connections (to computer) “B” -- downstream connections (to device) hub provides multiple connections hot-swappable

16. Firewire (IEEE 1394) data rates at 100, 200, and 400 Mbps self-configuring, hot-swappable new standard -- 800 Mbps common in consumer electronics
