USB stands for Universal Serial Bus. It is universal which means that this standard supports a vast array of devices such as printers, mp3 media players, scanners, data cable, speakers, and so on.This port allows a various devices to be attached to a laptop without needing a specific port or connector.
It is used to be simple. It has three connection such as USB 1.0, USB 2.0 and USB 3.0 . USB 1.0 connections existed for a brief time, but once USB 2.0 came along, with substantially better throughput, it became widely adopted. As with any widely adopted standard, variants appeared.
USB 2.0 is the standard port type. These days various electronics devices such as mice, keyboards, speakers, mouse, hard drives, scanners, optical drives, printers, and many more can be found in a USB 2.0 flavor to plug into one of these ports. This is still the most versatile connection compare to USB 1.0 or USB 3.0.
USB 3.0 is the latest version of USB, and is also known as SuperSpeed USB. It increases maximum throughput to 5 gigabits per second (625MB per second.) Most PCs implement USB 3.0 through a discrete chip built onto the motherboard, but some AMD chipsets have USB 3.0 built into the PC’s core logic. Intel will be building USB 3.0 into its core logic in its next-generation
USB Type – C
USB Type-C is a new, tiny physical connector. The 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 — so you have to make sure it’s oriented correctly when you plug it in.
But other devices wanted to use USB, too! Those massive USB ports won’t fit on smartphones, digital cameras, game controllers, and all the other devices out there you might want to plug in via USB. So many other shapes of connector were born, including micro and mini connectors. To get more information about different types of laptop USB ports, check this out .
