Parallel cable is the cable for computers defined by the IEEE 1284 standard for connecting peripherals via the parallel port. It is often used for connecting printers compatible PC computers. It is considered an outdated connection and has been replaced by USB. - IEEE 1284 Type A: 25-pin DB-25 IEEE 1284 - IEEE 1284 Type B: 36 Drivers, Champ type Centerline Connector 0.085 insurance (Centronics). - IEEE 1284 Type C: 36 conductors, connector type mini Champ de Centerline 0.050 with secure clip (mini Centronics).

SCSI, acronym for Small Computers System Interface (Small Computer System) is a standard interface for transferring data between devices on the bus of the computer. Types of SCSI SCSI one. 8-bit, 50-pin. Maximum length 6 meters Fast SCSI 2. 8 bits, 50 pins. Maximum length 3 meters Wide: 16-bit, 68-pin high density. Maximum length 3 metersUltra SCSI 3: 16-bit, 34-pin. Maximum length 1.5 meters. Ultra Wide: 16-bit, 68-pin. Maximum length 1.5 meters Ultra 2: 16-bit, 68-pin high density. Maximum length 12 meters.

The Centronics 36-pin Centronics 36-pin connector is arranged in two rows of terminals, each with 18 contacts. It has fastening clamps. Centronics connector 36 is typically used for connecting printers normally. Also can be called IEEE 1284 Micro Centronics 36-pin Micro Centronics connector has two rows of pins, each row has 18 contacts. This connector has clampsclamping. It is very similar to Centronics 36-pin connector but half his size. Can also be called IEEE 1284 Type C connector, this connector is mainly used for multi-function devices. The Centronics 50-pin Centronics 50-pin connector has two rows of pins, each row has 25 contacts. This connector has clamps. The Centronics 50-pin connector is the utilizADO SCSI-1 (scanners, hard drives) devices. A variation Centronics connector 50 used in voice applications, this variant is called Telco connector.
