external. The machine interface - is a system for connecting and interfacing nodes and computer blocks with each other. External interfaces -provide computer communication with external (peripheral) devices and other computers. Different PCs used and can be used: Bus extensions - general purpose bus, allowing you to connect a large number of a variety of devices; Local buses - often specializing in the maintenance of a small number of devices of a certain class, mainly video systems; Peripheral buses - interfaces for external storage and numerous peripheral slow-acting devices

Classification of PC interfaces

ISA bus: - 8-bit version - 16-bit The ISA bus is the fundamental basis of the architecture of personal computers

Tires of extensions

for connecting various devices. The main features of the bus are the following: - 32-bit or 64-bit data exchange. - The bus specification allows you to combine up to eight functions on one card (for example, video + sound, etc.).

Local bus (PCI bus)

buses (PCI-X bus)

32-bit PCI slot on top and
three 64-bit PCI-X slots from the bottom

to a separate AGP trunk The main features of the bus are the following: - increased throughput; - operating mode with DMA memory; - Ability to use video cards with higher power consumption than PCI.

Local buses (AGP bus)

(hard drives and optical drives) to a computer.

Peripheral Tires (ATA)

is designed to replace the old parallel ATA interface.

Peripheral buses (SATA)

Used for external implementation of the SATA interface.

Peripheral buses (eSATA)

Can be used for hot
hard drive connections
(BIOS requires AHCI mode).

to the computer. Theoretically, up to 127 devices can be connected to one USB host controller.

External interfaces for connecting peripherals (USB)

Mini USB

Micro USB

HDTV - with the built-in copyright protection mechanism Digital Rights Management (DRM).

External interfaces for connecting peripherals (HDMI)

HDMI can provide up to 8 channels of audio with a 24-bit capacity

signals

External interfaces for connecting peripherals (VGA and DVI)

The PC has long used a 15-pin interface
Mini-D-Sub for connecting the monitor (HD15) and today
It is superseded by DVI and HDMI interfaces.

DVI (Digital Visual Interface) - designed for transmission
video images to digital display devices.
