parts of a computer: CABLES

1. CABLES

2. ATA / PATA / ATAPI
/IDE
connectors
• Advanced Technology Attachment (ATA) is a standard
interface for connecting storage devices such as hard disks
and CD-ROM drives inside personal computers.
• Many synonyms and near-synonyms for ATA exist,
including abbreviations such as IDE and ATAPI
• original ATA was retroactively renamed Parallel ATA
(PATA).
• Created 1986 by western digital.
• Speed: 16 MB/s originally
later 33,66,100 and 133 MB/s

3. THE 34 PIN ATA CABLE

4. THE 40 PINS ATA CABLE

5. THE 80 PINS ATA CABLE

6. THE 80 PINS ATA CABLE IS
ALSO CALLED Ultra DMA

7. COLOR CODES ON 80 PINS
ATA CABLE
Color coding of the connectors is used to make it easier to
determine which connector goes with each device:
• Blue: The blue connector attaches to the host
(motherboard or controller).
• Gray: The gray connector is in the middle of the cable,
and goes to any slave (device 1) drive if present on the
channel.
• Black: The black connector is at the opposite end from the
host connector and goes to the master drive (device 0), or a
single drive if only one is used.

8. SCSI cable
• Widely used for RAID.
• SCSI is based on "SASI", the "Shugart Associates System
Interface", introduced by that company in 1979.
• Internal SCSI cables are usually ribbon cables that have
multiple 68 pin or 50 pin connectors. External cables are
shielded and only have connectors on the ends.
• Speed: 5 mb/s up to 640 mb/s.

11. SATA
• It was designed as a successor to the legacy Advanced
Technology Attachment standard (ATA), and is expected
to eventually replace the older technology (retroactively
renamed Parallel ATA or PATA)
• Created 2003.
• Speed: 1.5 Gbit/s, 3.0 Gbit/s
• Style: serial
SCSI Bcurrently offers transfer rates higher than SATA, but
is a more complex bus usually resulting in higher
manufacturing cost.
