Like all technology, USB has evolved over the time. Despite being a "Universal" connector in its decade long market, it has procreated multiple versions with different connection speeds and many types of cables.
In 2018, a report on global USB devices market size by Market Research Future revealed that the market gained close to a valuation of USD 19.00 Billion. And now, the market is anticipated to reach USD 46.08 Billion by the end of the projection period with a compound annual growth rate (CAGR) of 13.9%. This percentage of growth has made USB devices the most undefeated connectivity solution worldwide.
What is a USP Port?
A USB device is an ordinary device which has a cable connection interface for personal computers and consumer electronics devices. USB stands for Universal Serial Bus, a market evolving for short-distance digital data communications. USB devices are connected to the ports for connecting each other to transfer digital data over USB cables.
USB is a host-oriented and token-based serial bus protocol that allows a connection for up to 127 USB devices on a single USB host regulator. A host PC can also have multiple host controllers, which surges the supreme number of USB devices that can be linked to a single computer.
Brief History of USB Devices
Universal Serial Bus (USB) is a familiar interface that connects peripheral devices to a host computer. The USB system was initially developed by a group of companies such as Intel, IBM, Digital Equipment, Compaq, Microsoft, and Northern Telecom with an aim to replace the existing mixed connector system with the most straightforward architecture.
Earlier, USB devices were designed to replace the multitude of cables and connectors to connect peripheral devices to a host computer. The main aim of USB was to make the addition of peripheral devices quicker and easier. All USB devices share some essential characteristics to make this possible. Some devices can lure power from the USB, which excludes the need for extra power adapters.
Types of Ports
List of major types of physical layouts exist for USB ports into which USB devices are connected—
USB-A (Type A): The USB Type-A connector is nearly 1.4 cm (9/16 in) as well as length by 0.65 cm or (1/4 in) by height. It is characteristically used for wired mice and keyboards. USB gets connected generally to the USB-A connectors and performs function perfectly.
USB-B (Type B): Less known and common than type A, USB B devices are nearly found on computers, routers, printers, and game consoles.
Micro USB: Micro USB versions of both USB-A and USB-B exist in smaller versions than their base counterparts. These are popular for better connectivity in mobile devices. The older "mini USB" versions can also be found on many old devices.
USB Type C: With having dimensions of 0.84 cm by 0.26cm, this new standard is designed that replaces both A and B with smaller ports for better support, especially in mobile devices.
In 2010, the USB standard specifies came as a trend with different flavors of USB, such as full-speed, low-speed, high-speed, and SuperSpeed. USB-IF was also released; additionally, that expands the breadth of USB. These are On-The-Go (OTG) and Wireless USB.
