What is USB (Universal Serial Bus)?
A Universal Serial Bus (USB) is an interface that enables the communication between devices and a host controller such as a computer system. It connects peripheral devices such as digital cameras, mouse, keyboards, scanners, printers, media devices, flash drives and external hard drives. It has a wide variety of uses, including support for electrical power which is why the USB has replaced a wide range of interfaces like the parallel and serial ports,. There are different types of USB ports used to connect the peripheral devices to the computer. Some of them are:
- USB 1.x: It is an external bus standard that isa capable of data transfer with the speed of 12 Megabits per second and can support up to 127 peripheral devices.
- USB 2.0: it is also known as high-speed USB a maximum transfer speed of 480 Megabits per second. However, practically it is approximately 280 Mbps.
- USB 3.0: it is also known as SuperSpeed USB and was first made available in November 2009. It is a much-improved version of USB 2.0. It supports the data transfer rate of 5 Gigabits per second, which is much faster than the speed provided by USB 2.0.
- USB 3.1: It is also known as SuperSpeed+, and it was introduced in 2013. It is almost two times faster than USB 3.0 and can transfer the data at the rate of up to 10 Gigabits per second.
USB 2.0 and USB 3.0 are the ones that are majorly used in Computer Systems and Laptops. So, in this article, we will discuss the difference between USB 2.0 and USB 3.0.
Difference Between USB 2.0 and USB 3.0
Universal Serial Bus (USB) technology has revolutionized the way we join gadgets to computer systems, supplying a standardized interface for numerous peripherals. With the evolution of USB standards, notably USB 2.0 and USB 3.0, customers have skilled considerable improvements in statistics transfer speeds and capability. Understanding the variations between USB 2.0 and USB 3.0 is vital for choosing the ideal interface for distinctive devices and applications.
