▷ External connectors of a motherboard?

If you've ever opened your PC case and looked inside, you might be surprised by the number and variety of connectors, pins, and slots that exist on a modern PC motherboard. In this guide we will identify some of the most common (and some rare) connectors on motherboards that are used in most home PCs to connect external devices to them.

Surely, many of them will already be impossible to see on a current motherboard, but it does not hurt to know them so that you can identify them if you ever see them. External connectors on a motherboard. Let's get started1

The most important external connectors on a motherboard, everything you need to know

External connectors are used to connect various types of peripherals and devices to a PC. Most of these connectors are on the back of a motherboard, but some of them may also appear on your PC case. And if you have a laptop from many years ago, you will probably see some of these connectors on the sides.

VGA (L)

It is a 3 row 15 pin display connector that provides analog video output to a monitor. It is currently no longer in use,

Fiber

It is a high-speed connection that uses light to carry all kinds of signals. It is mainly used for wired connection to the network.

HDMI

It is a high definition connection to carry digital audio and video. It is typically found on televisions, monitors, and both desktop and laptop computers, to name a few devices.

DVI (K)

It is a 3-row 24-pin display connector that provides digital output to a monitor. It appeared before HDMI, and it is used less and less.

S-Video

Another video interface, also called Super Video, that transmits video using two signals: luminance, represented by a Y, and chrominance, represented by a C. It is round to accommodate a round plug with four pins.

PS / 2 (A) (B)

It is a 6-pin mini-DIN female connector to which a bruise or keyboard is connected. It is already deprecated due to the appearance of the USB interface for this type of devices

MMJ

It's like a phone jack, but with a scroll tab, commonly found on older mainframes.

Parallel (J)

It is a socket on the back of a motherboard to connect external equipment or peripherals, especially for printers. Currently it is hardly used.

Serie

This is a type of PC connection that is used for peripherals such as mice, game controllers, modems, and older printers. Normally, it is the slowest port you will find on a PC, if you find it.

USB (D)

It is the most common type of PC port. It can be used to connect keyboards, mice, game controllers, printers, scanners, digital cameras, and removable media drives. It is the interface that has been gradually replacing the others.

Audio (E)

It is an analog 3.5 mm connector, which connects audio equipment to a PC's sound card to facilitate data exchange.

Ethernet (F)

It is a port that is slightly larger than a standard telephone jack and transfers data at speeds of up to 10, 000 Mbps. It is used to connect a PC to a cable or DSL modem or to a network.

DisplayPort

It is a port that carries digital audio and video signals, and is found on many high-end graphics cards and monitors. It is currently the main alternative to the HDMI port, and is considered more advanced.

FireWire (H) (G)

It is a bus standard that supports data transfer rates of up to 400 Mbp s and can connect up to 63 external devices; a more modern version provides speeds of up to 3200 Mbps.

SCSI

It is a small computer system interface. It is a set of standards used to connect peripherals to computers. They are typically used for SCSI hard drives and / or tape drives.

Thunderbolt

Very similar to DisplayPort, it is a revolutionary I / O technology that supports high-resolution displays and high-performance data devices through a single compact port. It can be said that it is the most modern and advanced interface that exists today.
