Expansion Slots

> Serial Port

> Parallel Port

> USB

> Firewire (IEEE 1394)

29

Serial Port

> Serial Ports are cheap

> Transmit data one bit at a time.

> It is used in older PCs• Modem

• Mouse

• Keyboard

> Advantages• Cheaper

• Easier to shield from interference

30

Parallel Port

> Faster than Serial Ports

> Transmit data 8 bit at a time.

> It is used to connect• Printer

> Advantages• Faster

31

Fig. Just as more traffic can move along a multi-lane highway than in a one-

lane road, more data can move in Parallel port than in Serial Port.

32

USB

> Universal Serial Bus

> Several USB ports come outside the computer• Especially at handy spots

> USB connections are hot-swappable.

> Used for many kinds of devices• Keyboard

• Mouse

• Printer

• Audio in/out

• External Floppy

• Zip Drives

• Flash Drives

• 40 times faster than USB 1.0

34

Firewire

> High speed interface

> Developed by Apple Computers.

> The Sony version is called i.Link• Often called IEEE 1394

• Apple charges for using the name Firewire.

> Speeds• 400 kbits/sec (older version)

• 800 kbits/sec (latest version)

> Hot-swappable

> 65 daisy chained peripherals.
