USB full form is Universal Serial Bus. The Universal Serial Bus (USB) was introduced in 1994 by a consortium comprising seven different companies, Compaq, DEC, IBM, Microsoft, Intel, NEC, and Nortel. USB was designed to simplify the process of connecting external devices to a computer.
A USB device is compatible with a variety of devices like mice, keyboards, printers, scanners, speakers, and many more. It is also supported by many operating systems, including Android, Windows, Mac OS X, and Linux.
Not only exist on laptops and desktop computers USB is also used by smartphones and tablets to charge their batteries and transmit data to computers as well received.
In January of 1996, the Universal Serial Bus (version 1. 0) was made available for the first time to the public. This particular industry standard was then rapidly embraced by a variety of companies, including Intel, Compaq, and Microsoft, amongst others.

USB devices
There are a wide variety of USB devices that can connect to your computer today. The following list provides examples of some of the most typical.
USB printers, USB Disks, USB Keyboard, USB Mouse.
USB transfer speed
USB 1.0
An external bus standard known as USB 1.x can accommodate up to 127 peripheral devices and can facilitate data transfer rates of up to 12 megabits per second (Mbps). The image provides an illustration of a USB cable that has been attached to a USB port.
USB 2.0
Compaq, Hewlett-Packard, Intel, Lucent, Microsoft, NEC, and Phillips were among the companies that contributed to the development of USB 2.0, commonly known as high-speed USB, which was released in 2001. The maximum data transfer rate that can be supported by a Hi-Speed USB connection is 480 megabits per second (Mbps), which is equivalent to 60 megabytes per second (MBps).
USB 3.0
Buffalo Technology was the first company to make the USB 3.0 standard, also known as SuperSpeed USB, available to consumers in November 2009; however, approved devices did not become commercially available until January 2010. The USB 3. 0 technology was an improvement over the USB 2. 0 standard since it had better speed and performance, enhanced power management, and expanded bandwidth potential. It offers two data routes, each of which is unidirectional, so that users can simultaneously send and receive data. The USB 3.0 standard allows for data transfer speeds of up to 5.0 gigabits per second (Gbps), which is equivalent to 640 megabytes per second (MBps).
USB 3.1
As a result of the release of USB 3. 1, it has been given the official designation “USB 3. 1 Gen1” for the purposes of marketing. Motherboards produced by ASUS and Gigabyte Technology were among the first products to receive certification. Since April 2011, Dell has equipped its Inspiron and Dell XPS computer series with USB 3.0 connectors as standard equipment.
The most recent version of the USB protocol is known as USB 3. 1, which became available on July 31, 2013, and is also referred to by its previous name, SuperSpeed+. The transfer rates that may be achieved with USB 3. 1 are up to 10 Gbps, which places it on par with the first iteration of Apple’s Thunderbolt channel. Many gadgets on the market today make use of USB 3. 0 and 3. 1 versions, which offer enhanced performance and speed respectively.
USB ports alternatives
The serial and parallel ports that are found on older PCs can be replaced with USB ports as an alternative. The data transfer speeds that are supported by USB ports are sometimes 100 times or more higher than those supported by serial or parallel connectors.
When it comes to the networking of computers, Ethernet ports are sometimes utilized rather of USB ports. FireWire ports are also sometimes offered for use with specific varieties of computer accessories. Despite the fact that they do not transmit any electricity across the cable, Ethernet and FireWire are both capable of providing a performance that is superior to that of USB.
