All the electronic Ports Available



You didn’t think we were done right? nope, in this post, we will be finishing up with some other ports that weren’t mentioned in the previous post. This includes our USBs, all the types, yes there are more types than you might have thought.

1.USB Type-A

Also Known As USB Type-A, Regular USB Description: USB (universal serial bus) is the most common laptop and desktop connector known to man. The typical USB port is known as USB Type-A and has a simple, rectangular shape. Depending on the hardware, it can be capable of either USB-2.0 or USB-3.0 speeds. You can connect a nearly infinite universe of peripherals to a USB port, from keyboards and mice to printers and Ethernet adapters

2.USB Type-B

Description: You won’t find this square connector on any computer, but many hubs, docking stations, and printers use it as an input port. For these devices, you’ll need a USB Type-A–to–Type-B wire, which typically comes with the peripheral.


3.USB Type-C

Also Known As USB-C Description: This slim USB port is the connector of the future, already available on a number of devices and likely to replace USB Type-A, USB Type-B and MicroUSB on all new systems in the near future. Because it’s much thinner than its predecessors, Type-C can fit on extremely svelte laptops like the MacBook 12-inch and Asus ZenBook 3. It’s also reversible, so you never have to worry about putting your plug in upside down(the best feature about it). For better or worse, USB Type-C ports can support a number of different standards, so its uses are endless. But not all of them offer the same functionality. Type-C can transfer files at either USB 3.1 gen 1 (5 Gbps) or USB 3.1 gen 2 (10 Gbps) speeds. It can accept USB Power Delivery (USB-PD) so you can charge your laptop with it. It also sends DisplayPort signals out via its “alt mode,” and it can even operate as a Thunderbolt port. Manufacturers can indicate compatibility with USB 3.1 gen 2 with an “SS 10” logo or power delivery with a battery logo, but we don’t see these marks often. We do frequently see a lightning bolt next to the port, which indicates that it doubles as a Thunderbolt 3 port and can support the highest transfer rates and video out.

Adapters Needed: If you have a rectangular USB Type-A port and need to go to a USB Type-C dock or device, you can get A to C wire.


4.USB 2.0

Also Known As: High-speed USB, USB 2

Description: USB 2.0 is capable of transferring data at up to 480 Mbps, USB 2.0 is the most common speed of USB and works effectively with the majority of peripherals. A USB 2.0 port can come in a variety of shapes, including Type-A (rectangular), Type-B (square), mini or micro USB. On laptops and desktops, a USB 2.0 port will always be Type-A, while on tablets and phones, it will likely be micro USB.

5.USB 3.0

Also Known As: SuperSpeed USB, USB 3

Description: Great for external hard drives, SSDs, and high-res docking stations, USB 3.0 has a maximum transfer rate of 5 Gbps, more than 10 times that of its predecessor, USB 2.0. Ports for USB 3 are automatically backward-compatible with USB 2.0 cables and devices. USB 3 ports on a computer use a rectangular, type-A connector and are usually indistinguishable from their older counterparts. Sometimes these SuperSpeed ports will have light blue color or a tiny “SS” logo next to them to indicate their higher transfer rate, but not always. 

6.USB 3.1 Gen 1

Also Known As: USB 3.1, SuperSpeed USB

Description: USB 3.1 gen 1 is a connection protocol that’s the same 5-Gbps speed as USB 3.0, but it works only on USB Type-C ports. It’s backward-compatible with USB 3.0 and USB 2.0 devices, provided that your cable goes from Type-C to the appropriate connector. USB 3.1 devices may support USB Power Delivery, which allows them to receive or send power at up to 100 watts, enough to charge most laptops.

Adapters Needed: A USB 3.1 port has to use a Type-C connector, so it requires standard Type-C wires.


7.USB 3.1 Gen 2

Also Known As: USB 3.1, SuperSpeed+ USB, SuperSpeed USB 10Gbps

Description: USB 3.1 Gen 2 is just like USB 3.1 gen 1, but with double, the throughput, transferring data at up to 10 Gbps. It’s backward-compatible with USB Adapters Needed: USB 3.1 Gen 2 requires a Type-C connector, but to get it at full speed, you need to make sure your cable is rated for 10 Gbps.


8.Micro USB

Also Known As Micro-B, MicroUSB

Description: This small port is the charging connector of choice for smartphones and low-power tablets, but you probably won’t see it on a laptop or desktop. Regular micro USB ports support USB 2.0 speeds (480 Mbps), but there are a few devices, mostly external hard drives, that have micro USB 3.0 ports which have some extra pins and offer faster transfer rates. You can still use micro USB 2.0 wires and connectors in the micro USB 3.0 ports, however. Adapters Needed: To connect your laptop to a phone or your low-end tablet to its AC adapter, you’ll need a USB Type-A–to–micro USB cable, You can get a Type-C–to–micro USB adapter.



9.Mini USB

Also Known As Mini-B, mini USB

Description: Much less common than MicroUSB, the slightly larger mini USB is found on some external hard drives, game controllers (PS3 controllers for example) and other accessories. they cant be found on any computer, tablet or phone, but you can easily get a wire that goes from Type-A, Type-C or micro USB to mini USB.

Adapters Needed: A Type-A–to–mini USB cable , a Type-C–to–mini is available too and a micro USB-to-mini USB adapter


10.Thunderbolt 3

Also Known As Thunderbolt

Description: The fastest and most common connection you can find today, Thunderbolt 3 can transfer data at up to 40 Gbps, four times faster than the fastest USB connection (USB 3.1 gen 2). This high-speed standard can also output to up to two 4K monitors at once, because a single port carries dual DisplayPort signals. On some new devices today, you can use Thunderbolt 3 to connect to an external graphics card, which will allow you to play high-end games on an otherwise slim laptop. All Thunderbolt 3 ports use USB Type-C connections and double as USB Type-C ports, allowing them to connect to an entire universe of USB peripherals and, in most cases, to charge a laptop or tablet., There was a Thunderbolt 2 and original Thunderbolt standard which existed in the past years in computers that came out from 2015, but very few systems used them. With an adapter cable, you can connect your Thunderbolt 3 computer to older Thunderbolt devices.

Adapters Needed: You can get a Thunderbolt 3 cable, but be sure to read the specs before you buy; not all Thunderbolt cables can handle the full 40 Gbps, with some topping out at 20 Gbps. Thunderbolt 3 docking stations, which let you plug into a variety of monitors and peripherals. You can also use any USB Type-C cable, dock or device with a Thunderbolt 3 port.
