What is Back Panel?

The back panel of any computer is where you can attach devices like display, microphone, keyboard, and touchpad. The back panel is on the motherboard's border, as shown in the image below. The back panel is on the device's rear side and is put into the trial's I/O plate while attaching the motherboard.

The connectors just on the back panel are depicted in the illustration below. If you have never seen a motherboard before, it's the connectors on the rear of every computer that you are looking for.

What is back panel

Back panel interfaces were often joined or removed less frequently as compared to more available front panel connectors with the devices. Speaker jacks, foot switch jacks, and charger cord connectors, for example, are usually situated on the 'back panel' of a guitar amp because they will be rarely altered once connected in unless it is transported. The inputs and working loops on the front panel are frequently used throughout each use. Everywhere from PCs to DVRs would be affected in the same way.

Different types of back panels and their functions

1. Power cable receptor

A power line is an electrical wire made up of one or even more electrical cables regularly held together by a covering. The device is utilized for power transmission.

Conductors, insulating, and a protection cover are the three main components of cables. Individual cables have different compositions depending on the uses.

Three key elements influence the structure and material, which are as follows:

  • Working voltage, which determines the insulating layer.
  • Current-carrying ability, which determines the conductor(s) cross-sectional area.
  • The shape and substance of the outer wire coat are determined by environmental factors such as temperature, moisture, chemical or solar contact, and mechanical impact.

2. External monitor output port

As previously stated, current devices come with various monitor connectors, including HDMI, DVI, VGA, Display Port (DP), USB-C, Thunderbolt, and SDI.

Monitor with HDMI

The full form of HDMI is a high-definition multimedia interface. It is the primary communication interface in current homes entertainment devices such as flat-panel TVs and Blu-ray recorders. With HDMI, like with DVI, the signal is transferred in digital format, retaining the original content. HDCP Technology was designed to stop piracy and unauthorized copying of video content.

Monitor with USB port

Using the Display Link dongle, you can link a display with a DVI / HDMI socket to the USB port of any laptop or desktop. Such ports are commonplace for joining two devices, and all producers of these products are keen to implement them.

Mouse, keyboards, printers, lasers, modems, card readers, flash drives, cameras, cell phones, players, hard drives, optical discs, and other USB devices are all connected via USB ports. This connector is required for folks who intend to work and use many displays in a global setting.

3. Handler I/O Port

The E5071C controller I/O port has four different linear ports for data I/O, as well as many control signal channels and a power line. TTL logic is used for all signals.

Two pairs of 8-bit output terminals and two pairs of 4-bit bi-directional ports make up the information I/O ports. However, those ports can work together to give the highest 16-bit output port or an 8-bit incoming port.

Negative logic runs the I/O signals, which can often be changed. The control signal lines include multiple control output values, such as estimation accomplishment or a handshaking control signal.

4. Ethernet port

An Ethernet port is, however, referred to as a LAN port. On desktops, servers, modems, Wi-Fi routers, switches, as well as other network equipment, both data refer to a certain port.

Modems, routers, servers, personal computer towers, mini PCs, laptops, access points, video gaming consoles, and smart televisions all have LAN connectors.

An Ethernet wire and two Ethernet-capable devices are required for a LAN port to function properly. Attach the Ethernet cable to the LAN port on the internet-connected device, including a modem, router, or modem-router combo, and the desktop, gaming console, or another equipment end.

5. Rear USB port

All backside interfaces used to plug-in accessories and external devices are referred to as rear ports.
