- 5. Page 5 – 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. Interface connections.
- 6. Page 6 – 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. Interface connections.
- 8. Page 8 – 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). Interface connections.
- 9. Page 9 – 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. Interface connections.
- 10. Page 10 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). Interface connections.
- 12. Page 12 – 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. Interface connections.
- 13. Page 13 Interface connections. 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. Topic Internal interface connections. 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. External interface connections. 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. Other interface connections.
