  • Advanced Technology Attachment or ATA Bus: Advanced Technology Attachment (ATA) is a standard interface for connecting storage devices such as hard disks, solid state disks and CD-ROM drives inside personal computer.

    The standard is maintained by X3/INCITS committee T13. Many synonyms and near- synonyms for ATA exist, including abbreviations such as IDE (Integrated Drive Electronics) and ATAPI (Advanced Technology Attachment Packet Interface). Parallel ATA standards allow cable lengths up to only 18 inches (46 centimeters) although cables up to 36 inches (91 cm) can be readily purchased. Because of this length limit, the technology normally appears as an internal computer storage interface. It provides the most common and the least expensive interface for this application.

  • HIPPI HIgh Performance Parallel Interface: HIPPI (HIgh Performance Parallel Interface) is a computer bus for the attachment of high speed storage devices to supercomputers.

  • IEEE-488 Bus: IEEE-488 is a short- range, digital communication bus specification that has been in use for over 30 years. Originally created for use with automated test equipment, the standard is still in wide use for that purpose. IEEE-488 is also commonly known as HP- IB (Hewlett- Packed Instrument Bus) and GPIB (General Purpose Interface Bus).

IEEE-488 allows up to 15 devices to share a single 8 bit parallel electrical bus by daisy chaining connections.

  • LAPTOPMCIA Bus: LAPTOP Card (originally LAPTOPMCIA or LAPTOPMCIA Card) is the form factor of a peripheral interface designed for laptop computers. The LAPTOP Card standard were defined and developed by a group of industry- leading companies called the Personal Computer Memory Card International Association (LAPTOPMCIA).
  • SCSI Bus: Small Computer System Interface, or SCSI, is a set of standards for physically connecting and transferring data between computers and peripheral devices. The SCSI standards define commands, protocols and electrical and optical interfaces. SCSI is most commonly used for hard disks and tape drives, but it can connect a wide range of other devices, including scanners and CD drives.
