WHAT IS A USB?
The full form of USB is (Universal Serial Bus) a common interface that enables the communication between devices and a host controller such as a personal computer (PC) or smartphone.It connects peripheral devices such as Digital cameras, Keyboards, Printers, Media devices, Scanner, External hard drives, and Flash drives
The USB has replaced a wide range of interfaces like parallel and serial ports
So basically USB-C and USB-A are the different types of USB both types of USB are useful nowadays. Keep reading below to learn all the differences between USB C and USB A.
USB TYPE C or USB-C
USB-C is usually used for transferring data and charging your gadgets or anything.
Right now, this type of USB is coming with the newest Laptops, Mobile phones, and tablets, etc. It’ll spread to pretty much everything that currently uses the older, larger USB connector.
The specs of USB-C were first published in (2014).
it’s just in the last year that the technology has caught on. It’s now shaping up to be a real replacement for not only older USB standards, but also other standards like Thunderbolt and DisplayPort. Testing is even in the works to deliver a new USB audio standard using USB-C as a potential replacement for the 3.5mm audio jack. USB-C is closely intertwined with other new standards, as well—like USB 3.1 for faster speeds and USB Power Delivery for improved power-delivery over USB connections.
Type-C Features a New Connector Shape.
USB Type-C has a new, tiny physical connector—roughly the size of a micro-USB connector. The USB-C connector itself can support various exciting new USB standard like USB 3.1 and USB power delivery (USB PD).
The standard USB connector you’re most familiar with is USB Type-A. Even as we’ve moved from USB 1 to USB 2 and on to modern USB 3 devices, that connector has stayed the same. It’s as massive as ever, and it only plugs in one way (which is never the way you try to plug it in the first time). But as devices became smaller and thinner, those massive USB ports just didn’t fit. This gave rise to lots of other USB connector shapes like the “micro” and “mini” connectors.
Benefits of USB-C
This awkward collection of differently-shaped connectors for different-size devices is finally coming to a close. USB Type-C offers a new connector standard that’s very small. It’s about a third the size of an old USB Type-A plug. This is a single connector standard that every device should be able to use. You’ll just need a single cable, whether you’re connecting an external hard drive to your laptop or charging your smartphone from a USB charger. That one tiny connector is small enough to fit into a super-thin mobile device but also powerful enough to connect all the peripherals you want to your laptop. The cable itself has USB Type-C connectors at both ends—it’s all one connector.
USB-C provides plenty to like. It’s reversible, so you’ll no longer have to flip the connector around a minimum of three times looking for the correct orientation. It’s a single USB connector shape that all devices should adopt, so you won’t have to keep loads of different USB cables with different connector shapes for your various devices. And you’ll have no more massive ports taking up an unnecessary amount of room on ever-thinner devices.
PROTOCOLS of USB-C
USB Type-C ports can also support a variety of different protocols using “alternate modes,” which allows you to have adapters that can output HDMI, VGA, DisplayPort, or other types of connections from that single USB port.
Apple’s USB-C Digital Multiport Adapter is a good example of this, offering an adapter that allows you to connect an HDMI, VGA, larger USB Type-A connectors, and smaller USB Type-C connector via a single port. The mess of USB, HDMI, DisplayPort, VGA, and power ports on typical laptops can be streamlined into a single type of port.
USB Type-A or USB-A
USB Type-A connectors, officially called Standard-A connectors, are flat and rectangular. Type A is the “original” USB connector and is the most recognizable and commonly used connector.
The USB Type-A connectors are supported in every USB version, including USB 3.0, USB 2.0, and USB 1.1.
USB 3.0 Type-A connectors are often, but not always, the color blue. USB 2.0 Type-A and USB 1.1 Type-A connectors are often, but not always, black.
NOTE: The part of the USB Type-A cord that plugs into a device is called the plug or a connector and the part that accepts the plug is called the receptacle but is commonly referred to as the port.
Uses for USB Type-A
USB Type-A ports/receptacles are found on almost any modern computer-like device that can act as a USB host, including, of course, computers of all kinds including desktops, laptops, netbooks, and many tablets.
The USB Type-A ports are also found on other computer-like devices. Such as video game consoles (PlayStation, Xbox, Wii, etc.), home audio/video receivers, “smart” televisions, DVRs, streaming players (Roku, etc.), DVD and Blu-ray players, and more.
Most USB Type-A plugs are found at one end of many different kinds of USB cables. Each designed to connect the host device to some other device that also supports USB,
USB Type-A Compatibility
The USB Type-A connectors outlined in all three USB versions share the same form factor. This means that the USB Type-A plug from any USB version. Will fit into the USB Type-A receptacle from any other USB version and vice versa.
That said, there are some significant differences between USB 3.0 Type-A connectors and those from USB 2.0 and USB 1.1.
Benefits of USB Type-A
As we see in laptops, Xbox, Playstation we all can get these ports. These ports are very common and useful too so we can’t deny the USB-A too on the behalf of USB-C.
We can just plug and play many things with this USB like Keyboards, Mouse, Joystick, etc.
As we know that the USB-A release date is August 1998 and the USB-C officially released on 11 August 2014
So obviously USB-C has the new technology and the speed. Which is much faster than USB-A but still, USB-A is very useful. Nowadays as we can see we have USB-A ports in Laptops, Xbox, etc.
