Technology seems to show no signs of slowing down when it comes to advancements and innovations. Whether it be laptops, PCs, or Macs, there are a wide range of computer ports to keep track of and make use of.
While there has been a concerted effort by industry leaders to move in the direction of a multi-use cable, we’re not quite there yet. We’ve come up with a list to help you stay up to date on the latest and more traditional types of computer ports.
USB Type-A
This is the most common port found on all laptops and desktops. The near universal use of USB Type-A means you can easily connect a wide range of peripherals and devices straight to your computer, such as keyboards, mice, printers, microphones, external storage devices, and more. However, speeds when using this port can differ as USB-2.0 (slower) and USB-3.0 (faster) have different technological limitations.
USB Type-B
The USB Type-B connector isn’t a laptop or PC port, but it’s used on many printers, docking stations, and hubs. The wire is normally a USB Type-A to a USB Type-B, meaning you can plug one end into your computer and the other into an external device.
USB Type-C
Also known as USB-C, this version of the USB port is slimmer, faster and more versatile than the rest. It’s likely that you’ll only see this type of computer port in the future as it’s already replacing USB Type-A, USB Type-B and microUSB on new computers.
However, there are a few variants of the Type-C PC port, with benefits including: 5-10 Gbps transfer speeds, USB power delivery (charge laptops), and sending out DisplayPort signals thanks to its “alt mode”.
USB 3
USB 3 computer ports look virtually identical to the older models and are backwards compatible. This means you can continue to use all your old USB 2 peripherals by connecting them to a USB 3 port. However, the main draw for USB 3 is the far faster transfer speeds of 5 Gbps which are ideal for external hard drives and solid state disks (SSDs).
Thunderbolt 3
Apple’s Thunderbolt 3 is the fastest connection you’ll find on the market for the general public. It can transfer data at lightning fast speeds of 40 Gbps and the port also doubles as a USB Type-C connection, making it even more versatile than it already is.
Notably, Thunderbolt 3 can also provide double the video bandwidth of any other cable on the market and supply up to 100W of power. This means that this single connection can power displays, transfer data extremely fast, daisy chain external devices, and provide a power connection.
HDMI
HDMI ports can carry video and audio signals through a single connection, but your resolution will depend on the capability of your graphics card. Typically, HDMI ports will connect PCs and laptops to TVs, projectors and other types of external monitors.
DisplayPort / mini DisplayPort
DisplayPort is the most technologically advanced display connection available, offering 4K resolution with 60 Hz from a single monitor or up to 3 monitors at full HD. Laptops and smaller computers normally use a mini DisplayPort connection or send their video signal through a USB Type-C port.
Digital Visual Interface (DVI)
You’ll only find a DVI connection on desktop PCs and it’s normally cheaper than the DisplayPort connection. However, it does come with limitations, such as having a maximum output resolution of 1920×1200 and needing a second connection in order to support a 4K monitor.
