All the electronic Ports Available


Ports, whether we like it or not we must use them and using them means knowing each one that might be useful to them. We don’t know that there’s a wide variety of ports available to us now but we know just a few. From traditional USB to newfangled USB Type-C and Thunderbolt 3 ports. Even if you’re familiar with the most common connectors, it can still be a challenge to figure out what wires or adapters you need in order to plug your device into a monitor, TV, network or peripheral. So Am going to widen your scope of when it comes to the varieties of Computer ports we know, Giving you the names, description and possible adapters that can be used if you’re in dye need of but lack any of the ports mentioned.

1. 3.5mm Audio Jack

Also Known As Headphone jack
Description: The most common audio jack in the world, the 3.5mm audio jack appears on most computers, tablets, and phones, and connects to the majority of the world’s wired headphones and speakers. While some older devices have two audio jacks for mic and headphones, most current models incorporate both into the same port. But some newer devices like the phones, including the iPhone 7, omit this jack.
Adapters Needed: If your device lacks a 3.5mm jack, you can buy a wired USB headset, attach a wireless Bluetooth audio device or get an adapter. If you have an iPhone, get a Lightning to 3.5mm cable or Lightning headset. If you have a USB Type-C-powered device, get a Type-C to 3.5mm adapter or Type-C headphones. And this will work just as good

2. Ethernet

Also Known As RJ-45, Gigabit Ethernet, 10/100 Ethernet
Description: Found primarily on business laptops and on desktops, this port allows for direct connection to wired networks. While Wi-Fi continues to improve, having the option to plug in via Ethernet is really valuable, particularly when you’re in a location with a poor wireless signal. Some spec sheets refer to this port as “Gigabit Ethernet” or “10/100 Ethernet,” but all modern laptops and desktops with this port operate at up to 1 Gbps.
Adapters Needed: If you don’t have an Ethernet port built-in, you can purchase a USB-to-Ethernet adapter, depending on whether you are connecting to a USB Type-C or traditional, USB Type-A port. You can also get Ethernet by connecting to a docking station.


HDMI stands for High-Definition Multimedia Interface, and its the most popular port used when connecting to TVs and also appears on many external monitors and projectors. Depending on your laptop’s or desktop’s graphics card, the machine’s port may be able to output at up to 4K resolution. However, you cannot output to dual displays from a single port. HDMI sends audio along with its video, so if your monitor or TV has speakers, you’ll get sound too. If your computer has HDMI-out and your external display has DVI, you can convert from one to the other with an adapter. While most laptops that have HDMI use the full-size port, there are a few superslim devices that employ mini HDMI connectors. These are a bit smaller, and it’s more difficult to find adapters for them.
Adapters Needed: If you need to connect to DVI, an HDMI-to-DVI plug. You can also get an adapter that goes from USB Type-C to HDMI, provided that your Type-C supports video.

4.microSD card reader

Also Known As microSD card slot, microSDHC reader, microSDXC
Description: This slot reads tiny microSD memory cards, the kind that smartphones use for external storage. If your laptop or tablet has very limited internal storage and you have the reader, getting one of these inexpensive cards could really help you out.
Adapters Needed: If you don’t have a built-in slot, you can get a USB-based external microSD reader.

5.SD Card Reader

Also Known As a 3-in-1 card reader, 4-in-1 card reader, 5-in-1 card reader, SDHC card reader Description: This is a slot that you can use to read the memory cards from a digital camera. If you frequently transfer pictures from a DSLR or mirrorless camera to your laptop or desktop, having a built-in reader is a bonus convenience.
Adapters Needed: If you don’t have a built-in SD card reader, you can buy one that connects through USB.


Description: The oldest of video outputs, VGA also known as (video graphics array) is one of the oldest and dates all the way back to 1987 but is still commonplace on many monitors and projectors today. However, because the 15-pin connector is rather chunky, you won’t find too many current-gen laptops or desktops that have VGA-out. It is an analog connection, which could lead to signal degradation over longer cables, and it outputs at only up to 1920 x 1200, so it’s the least desirable port.
Adapters Needed: You can’t convert VGA to any other display standard (DVI, DisplayPort, HDMI), but you can plug any other connector into a VGA monitor with a wire or adapter. You can get DVI-to-VGA, HDMI-to-VGA or DisplayPort-to-VGA converters
