Frequently Asked Questions (FAQs)

1. What is a SCSI cable used for?

A SCSI connector (/ˈskʌzi/ SKUZ-ee) is used to connect computer parts that use a system called SCSI to communicate with each other. Generally, two connectors, designated male and female, plug together to form a connection which allows two components, such as a computer and a disk drive, to communicate with each other.

2. What are the 3 types of SCSI data cables?

Cables and Connectors As we mentioned in the basic section above, there are three predominate types of internal SCSI connectors. IDC 50 (Internal Data Connector, 50 pins), HPDB 68 (Half-Pitch Data Bus, 68 pins), and SCA (Single Connection Adaptor).

3. What are the two basic types of cabling for SCSI?

SCSI devices come in two basic types:. Single-ended devices: Use one data lead and one ground lead to establish single-ended signal transmission over the bus. ... Differential devices: Use two data leads, neither of which are at ground potential.

4. What are SCSI drives?

SCSI (Small Computer Systems Interface) is a smart bus, controlled with a microprocessor, that allows you to add up to 15 peripheral devices to the computer. These devices can include hard drives, scanners, printers, and other peripherals.
