The document outlines various types of interface connections, including IDE, EIDE, SATA, USB, Firewire, and other standards used for peripheral and network connectivity, detailing their specifications and maximum transfer rates. It highlights the advancements from older technologies like IDE/EIDE to newer standards such as SATA, and discusses both wired and wireless communication methods including Bluetooth and infrared. Additionally, the document includes a note on the funding and equal opportunity provisions related to the Pace-IT program at Edmonds Community College.

– IDE
» The Integrated Drive Electronics (IDE) interface used a
40 pin 40 wire ribbon cable that could be up to 18 inches
long and had three connections on it (one for the
motherboard and two for peripheral devices). The
connectors were keyed so they could only be inserted
one way.
» It had a maximum transfer rate of 8.3 MBps.
» IDE was associated with parallel advanced technology
attachment (PATA) devices.
– EIDE
» The Enhanced Integrated Drive Electronics (EIDE)
interface uses a 40 pin 80 wire ribbon cable (same
physical dimensions and layout as the IDE cable).
» It has a maximum transfer rate of 167 MBps.
» EIDE is associated with parallel advanced technology
attachment (PATA) devices.
» EIDE is backward compatible with IDE.

– SATA.
» The Serial Advanced Technology Attachment (SATA)
interface is the replacement for the IDE/EIDE interface. It
uses a seven wire seven pin cable that has an L shaped
keyed connector and it can be up to one meter in length.
» Unlike the IDE/EIDE interface, only one SATA device is
allowed per cable.
» All SATA devices are hot swappable.
» SATA 1 has a maximum transfer rate of 1.5 Gbps.
» SATA 2 has a maximum transfer rate of 3.0 Gbps.
» SATA 3 has a maximum transfer rate of 6.0 Gbps.
» eSATA (External SATA) brings the high speed SATA
interface outside of the computer case. It allows for up to
a two meter long cable and can perform at SATA 3 levels
with external drives that support it.

– USB.
» The Universal Serial Bus (USB) interface was introduced in
1998 and has been through several iterations.
» The standard allows for chaining multiple devices together—
up to 127 devices plus the controller.
» The interface not only provides a data bus, but also enough
power to run small devices.
» USB 1.1 and USB 2.0 have a maximum cable length of five
meters, while USB 3.0 does not have a maximum cable
length.
» All USB standards are backward compatible.
» USB 1.1 has a maximum transfer rate of 12 Mbps.
» USB 2.0 has a maximum transfer rate of 480 Mbps.
» USB 3.0 has a theoretical maximum transfer rate of 5.0 Gbps.
» The USB standard calls for different types of physical
connectors (A, B, mini, and micro).

– FireWire.
» The interface and standard were developed by Apple and
introduced in 1999; it has also been through several
iterations.
» The FireWire connection was standardized by the
Institute of Electrical and Electronics Engineers (I.E.E.E.)
as I.E.E.E. 1394.
» The standard allows for up to 16 devices to be chained
together.
» The maximum allowed cable length is 4.5 meters.
» The various standards are backward compatible.
» FireWire 400 has a maximum transfer rate of 400 Mbps.
» FireWire 800 has a maximum transfer rate of 800 Mbps.

Serial/parallel.
The legacy standard for
peripheral devices.
Most PCs no longer come equipped
with these interface connections,
having been replaced with the more
versatile USB interface instead.
VGA/DVI/HDMI.
Interface standards for
connecting monitors.
Video Graphics Array, Digital Video
Interface, and High Density Media
Interface. What is present will
depend upon the graphics
capabilities of the PC.
RJ-45/RJ-11.
Interface standards for
twisted pair wires.
Ethernet networking heavily relies
upon the RJ-45 interface, while the
RJ-11 is used with plain old
telephone service (POTS).

– Infrared (IR).
» Line-of-sight only (the devices must be in visual range).
» Uses the IR band of light to communicate between
devices.
» Has a distance limitation of approximately three feet.
– Radio Frequency (RF).
» This encompasses various standards that involve
communicating via radio waves.
» Distance is limited by the power of the transmitting
device.
» Speed is limited by the standards employed.
– Bluetooth.
» A low power personal area network (PAN) standard for
creating an RF connection.
» Operates on the 2.4 gigahertz (GHz) radio frequency.
» Has an effective range of 10 meters, but the transfer rate
drops as the distance between devices increases.

IDE/EIDE were the industry standard interfaces for many years. IDE used a
40 pin 40 wire cable, EIDE uses a 40 pin 80 wire cable. SATA is the newer
interface standard and has higher performance values. SATA 3.0 has a
maximum transfer rate of 6.0 Gbps. SATA uses a seven pin seven wire
connector.

Summary
The USB interface can chain together up to 127 different devices. USB has
a maximum transfer rate of 6.0 Gbps. FireWire allows up to 16 devices on a
single interface. FireWire 800 has a maximum transfer rate of 800 Mbps.
Other external interfaces include: serial/parallel, VGA/DVI/HDMI, and RJ-
45/RJ-11 type interfaces.

IR interfaces are limited by line-of-sight issues and are a slower older
standard. RF interfaces encompass any standard that involves the use of
radio frequency communications. Bluetooth is a type of RF interface that
creates a PAN on the 2.4 GHz band.
