We know that technology evolves faster and further every day
and it can sometimes feel overwhelming. That’s why we’ve
partnered with StarTech.com, a global leader in manufacturing top-
quality USB cables and connectivity solutions, to bring you this

Guide.
Here, you’ll learn everything you need to know about the various
types of USB cables, what the USB versions mean for transferring
your data, and how they work.
USB stands for Universal Serial Bus and is an umbrella term used to
describe the most common port type: the rectangular USB, known as
USB A. Typically, USB ports are found across multiple devices, such
as phones, PCs, and gaming consoles.
Initially developed in the mid-90s, the USB connection was created
to standardize ports for peripherals. This is so secondary devices,
like printers and keyboards, can connect to a wider range of
computers and hosts, rather than a select few with specific
receptacles.
Today, there are a variety of USB types, but the main use of all
USBs has remained the same: to transfer data and power. Over time,
new versions have been released to improve transfer speeds and
power output.
StarTech.com are the experts when it comes to how this technology
works. The industry leaders explain a [url=http://www.china-
topscable.com/usb-cable/usb-2-0-cable/]USB 2.0 cable[/url]
connection like this:
“If you were to open up a USB cable, you would notice 4 different
USB wire colours: white and green, which carry data, and red and
black, which are used for power. Red carries 5 volts and acts as
the positive wire, while black is the negative wire, otherwise
known as the ground wire.
Each type of USB connection (USB cable type A, B, C, micro and
mini) has a pinout system, these are the small metal strips inside
the connector, designed to access each of these wires and their
capabilities.”
Over the last 25 years, there have been several different USB
cables and iterations, depending on the USB protocol. The USB
started with version 1.0, which transfers up to 12Mbps and was
released in 1995. The latest today is USB version 4, which
transfers up to a massive 40Gbps.
StarTech.com know that users want the best USB for the job, which
is why they have created a table below to help decipher the speed
and capabilities of each version.
As with USB versions, the shape of the USB connection has also seen
drastic changes over the years. With each new evolution of USB
type, their form factor generally becomes smaller to accommodate
for new, much thinner devices that are popular during the time of
release.
The USB C design, which is the latest USB release, is unique
because it’s the only USB that fits into another port type not
specifically created for it: Thunderbolt 3. They are both the same
shape and users can employ Thunderbolt 3 and USB C cables and ports
interchangeably. All other male and female USB connector types only
fit their corresponding male and female ports. For example, a USB
port type b will only accept a USB type B connector.
The version or speed of the technology is dictated by the host
device, connecting peripheral, and the version of the
[url=http://www.china-topscable.com/usb-cable/usb-3-0-cable/]USB
3.0 cable[/url], not the shape of the port.
Backwards compatibility means that the latest version of something
is still capable of using previous versions. For example, a USB A
3.0 port is capable of recognising and utilising a USB A 2.0
peripheral.
For the newer USB C, it’s still possible to connect older USB
supported devices to a USB C port or host, via an adapter.
StarTech.com provide an extensive range of [url=http://www.china-

Degree USB Cable[/url], which can be used if the host and
peripheral have different port types. Adapters, or connectors, can
be found for all USB types and are not limited to USB C.
When using previous USB versions, the performance is limited to the
earliest version that’s being used. For example, if you want to
transfer files from a 2.0 USB A enabled hard drive to a laptop with
USB A 3.0 ports, the transfer rate (USB speeds) would be limited to
480Mbps.
USB-C is the latest advancement in USB connectivity and has been
dubbed by many as “future proof.” It is conveniently reversible
and has a much more compact shape compared to previous USB cable
types. A USB C cable not only deals with data and power, but also
video. It supports multiple protocols and carries DisplayPort and
HDMI signals (when in Alt mode), as well as Thunderbolt 3 for
equipped devices. Also, like other USBs, it’s capable of backwards
compatibility from USB 1.1, but functions with the latest USB 3.2
Gen 2.2 devices as well.
This type of connector looks and is physically the same as a
Thunderbolt 3 port. Thunderbolt 3 and USB C ports and cables can be
used interchangeably and utilised for data transfer, power output,
and video. When using a Thunderbolt 3 port with a USB C cable,
users can charge full-size electronics with up to 100W of power
output. Even better, the top data transfer speed is 40Gbps with a
Thunderbolt 3 port, meaning you can be more productive.
Universal Serial Bus (USB) was developed in the 1990s in an effort
to simplify the connections between computers and peripheral
devices. It has become widely popular due to its compatibility with
many platforms and operating systems, its low cost of
implementation, and its ease of use. Most computers that are built
today come with several USB ports, and USB is the interface of
choice for most home and office peripherals including printers,
cameras, modems, and portable storage devices.
USB standards are developed and maintained by an industry body
called the USB Implementers Forum (USB-IF). In its original
specification, USB defined only two connector types: A and B.
Revisions to the specification and demands on manufacturers have
expanded the breadth of connectors used for USB devices, but the
majority of USB products still use these A and B connector
interfaces.
