The ATA (Advanced Technology Attachment English) or PATA interface, originally known as IDE (Integrated Device Electronics) is an interface standard for connecting devices massive data storage and optical drives that uses the standard ATA derivative and the ATAPI standard.

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.

A connector IDC (insulation-displacement connector) connector IDT (insulation-displacement technology/termination) or insulation displacement connector is an electrical connector designed to be connected to a driver (or drivers) of an insulated wire through a connection process by selective isolation through one or more sharp blades, avoiding the need to strip the cable cover before connecting.The ribbon cable (also known as strip wire or ribbon cable) is designed for use in multi-pin IDC connectors so that the IDC connections can do at once, saving time in applications where many connections are required. These connectors are not designed to be reusable, but can be used again if care is taken to remove the cable.

The system of differential low voltage signal or LVDS is a system for transmitting high speed signal transmission on cheap media, such as twisted pair. It was introduced in 1994 and became popular in computer networks for high speed data transmission. The aim of the differential transmission is able to more easily recover the signal in the receiver, because it is easier to checkwhich signal is more positive than the other, you get the signal potential.
