The IDE interface is also known as:?

Question

a. ATA.
b. PATA
c. SATA.
d. SCSI

Answer 1

IDE = ATA = PATA

They started calling it PATA after the introduction of SATA.

Edited. Essanai_how1 you take me back years, most people don't remember MFM, RLL, and ESDI anymore.

Answer 2

Abbreviation of either Intelligent Drive Electronics or Integrated Drive Electronics, depending on who you ask. An IDE interface is an interface for mass storage devices, in which the controller is integrated into the disk or CD-ROM drive.
Although it really refers to a general technology, most people use the term to refer the ATA specification, which uses this technology. Refer to ATA for more information.

Answer 3

Notable drive families include:

MFM (Modified Frequency Modulation) drives required that the controller electronics be compatible with the drive electronics.
RLL (Run Length Limited) drives were named after the modulation technique that made them an improvement on MFM. They required large cables between the controller in the PC and the hard drive, the drive did not have a controller, only a modulator/demodulator.
ESDI (Enhanced Small Disk Interface) was an interface developed by Maxtor to allow faster communication between the PC and the disk than MFM or RLL.
Integrated Drive Electronics (IDE) was later renamed to ATA, and then PATA.

The name comes from the way early families had the hard drive controller external to the drive. Moving the hard disk controller from the interface card to the drive helped to standardize interfaces, reducing cost and complexity.

The data cable was originally 40 conductor, but UDMA modes from the later drives requires using an 80 conductor cable (note that the 80 conductor cable still uses a 40 position connector.)

The interface changed from 40 pins to 39 pin. The missing pin acts as a key to prevent incorrect insertion of the connector, a common cause of drive and controller damage.

SCSI (Small Computer System Interface) was an early competitor with ESDI, originally named SASI for Shugart Associates. SCSI drives were standard on servers, workstations, and Apple Macintosh computers through the mid-90s, by which time most models had been transitioned to IDE (and later, SATA) family drives. Only in 2005 did the capacity of SCSI drives fall behind IDE drive technology, though the highest-performance drives are still available in SCSI and Fibre Channel only. The length limitations of the data cable allows for external SCSI devices. Originally SCSI data cables used single ended data transmission, but server class SCSI could use differential transmission, and then Fibre Channel (FC) interface, and then more specifically the Fibre Channel Arbitrated Loop (FC-AL), connected SCSI hard drives using fibre optics. FC-AL is the cornerstone of storage area networks, although other protocols like iSCSI and ATA over Ethernet have been developed as well.

SATA (Serial ATA). The SATA data cable has only one data pair for the differential transmission of data to the device, and one pair for receiving from the device. That requires that data be transmitted serially. The same differential transmission system is used in RS485, Appletalk,USB, Firewire,and differential SCSI. In 2005/2006 parlance, the 40 pin IDE/ATA is called "PATA" or parallel ATA, which means that there are 16 bits of data transferred in parallel at a time on the data cable.

SAS (Serial Attached SCSI). The SAS is a new generation serial communication protocol for devices designed to allow for much higher speed data transfers and is compatible with SATA. SAS uses serial communication instead of the parallel method found in traditional SCSI devices but still uses SCSI commands for interacting with SAS

EIDE was an unofficial update (by Western Digital) to the original IDE standard, with the key improvement being the use of DMA to transfer data between the drive and the computer, an improvement later adopted by the official ATA standards. DMA is used to transfer data without the CPU or program being responsible to transfer every word. That leaves the CPU/program/operating system to do other tasks while the data transfer occurs.

Answer 4

the IDE interface is also known as Parallel ATA which is pretty annoying. I presonally perefer the Serial ATA cables.

Answer 5

PATA (for hard drives at least)

It used to be just ide but then sata drives came out and they changed it I guess. I must have missed that.

Answer 6

pata

Answer 7

Pretty sure it's ATA.

Why?
