laptop ports
If you have a laptop, especially a business or work notebook, it is quite possible that it’s laced with many ports, and sometimes, it could become overwhelming to keep track of their names or function. This is a snafu that laptop users that are not so tech-savvy have to contend with. Some of those ports even come in various versions.

opposed to the belief of a handful of laptop owners, ports are not meant for aesthetical purposes. For
this reason, today’s how-to article will inform you about the common (as well as uncommon) ports that you
would see on laptops, their functions, available versions or types. We will
also show you to easily identify ports on your

USB Ports

acronym which stands for Universal Serial Bus, USB is the most common port that
is found on a laptop. If you are a
MacBook Pro user, it is the only available port you would see on this laptop.
USB ports are typically employed for file
transfer between your laptop as well as
other devices, which could be laptops, smartphones, storage disks, and so on. They
are also used as attaching and charging peripherals and occasionally function as the
charging point of a laptop.

There are various types of USB connection ports, each with their individual unique features. As of now, there are 3 types of USB ports.

USB Type-A

Also called USB-A, this is a 4-pin connector, available in various types and versions, such as USB 1.1, USB 2.0, USB 3.0 as well as USB 3.1. The USB 2.0 typically comes in colour Black or Gray, whereas the USB 3.0 ports are offered in Blue or Turquoise colour. The USB 3.0 has been given a new name, USB 3.1 Gen 1, by the USB Implementors Forum.

USB 3.0 does not exist any longer, technically. If you come across a laptop
that features a USB 3.0 port, it might be some years old. But there is another
version of the USB 3.1 that is known as the Gen 2 and offers 10Gb/s transfer
rate, twice that of the Gen 1, 5Gb/s.

To determine the specific generation
(or speed) of USB 3.1 that your laptop offers, you would need to check the specs
sheet of your device as it’s specified, always, by the manufacturer. Or better
still, you can take these steps:

  • Right -click on My Computer/This PC
  • Press Manage
  • Choose Device Manager
  • Expand Universal Serial Bus controller; you can now see detailed info on the USB types and versions of your laptop.

USB Type-C

USB Type-C is the newest and latest type of USB connection port, also called USB-C. It is rapidly replacing the USB Type-A on laptops as well as Type-B on other devices. The USB Type-C, unlike the rectangle-shaped Type-A with four-pin connector, is smaller and slimmer and has twenty-four pins making it handle faster transfer speed and higher currents.

Since laptops and notebooks are becoming
slimmer, the USB-C port is being employed by a
lot of manufacturers over the Type-A.

RJ-45 Ethernet Port

RJ is an acronym for Registered Jack. An RJ-45 Ethernet port is used for connecting to the internet on the laptop via a compatible ethernet cable. This connection port has an 8 pin – 8 contact (8P – 8C) connector and comes with two LED lights, occasionally, which indicate packet detection as well as transmission.

for High Definition Media Interface, HDMI port enables the transfer of audio
and video signals between the laptop and other gadgets,
such as digital cameras, laptops, monitors, projectors, game consoles, and so
on. Concerning HDMI versions, HDMI 2.1 is the latest
version while older ones are the HDMI 1.4 and HDMI 2.0.

The HDMI 2.1 offers enhanced audio and better visual features and capabilities than the HDMI 2.0; just like
the 2.0 is better than the 1.4. But it isn’t so
straightforward to show you the difference in the port versions physically
because they all have similar 19-pin
connector and are also backward compatible. To determine the version of the HDMI port of your laptop, you
can check the user’s manual or do a simple Google search.

Types of HDMI Connection Ports

4 different types of HDMI ports are currently available and unlike the versions, they can be identified easily using physical examination. Types of HDMI ports are, HDMI Type-A (standard), HDMI Type-C (mini HDMI), Type-D (micro HDMI), and lastly, Type-E.

Types A, C, and D are utilized on laptops, typically, whereas Type-E is specifically made use of in automotive applications.

ThunderBolt 3

this connection port is identical to your regular USB Type-C port,
both work using different protocols. The ThunderBolt 3is, basically, a USB-C port supporting higher and
faster transfer speed that is as much as 40Gb/s, which is 4 times that of regular USB-C Gen 2.

ThunderBolt 3 ports can also serve the same role as a USB-C port; however, not
all USB-C ports come with ThunderBolt 3 features.

port, like HDMI above, features a 20-pin connector and is also capable of
sending video and audio signal to external display devices, such as your
monitor. 2 types of DisplayPorts are available on
modern-day laptops: mini DisplayPort and standard DisplayPort.

DisplayPorts are mostly seen on Apple’s
MacBook Pro and Microsoft’s Surface Pro tablets. And standard full-size
DisplayPorts typically come with bigger-sized laptops and most times feature a
locking mechanism, which prevents attached cables from accidentally disconnecting.

That’s all on
laptop ports and their different types/version.
