In layman’s terms, what does USB stand for?

In order to enable communication between devices and a host controller, such as a PC or smartphone, a Universal Serial Bus (USB) is used. An Omron universal serial bus controller in Malaysia is a device that links peripheral devices such as cameras, keyboards, printers, scanners, and media players to a computer. A wide range of interfaces, such as the parallel and serial port, have been supplanted by the USB because of its numerous purposes, including electrical power support.

The purpose of a USB is to make it easier to plug in and play, as well as to enable hot switching. Without restarting the computer, plug-and-play allows the operating system (OS) to automatically configure and discover a new peripheral device. As an added bonus, hot swapping makes it possible to swap out a peripheral device without having to restart the computer.


USB connectors come in numerous varieties. Type A and Type B USB cables used to be the most common varieties of USB cords. Type A USB 2.0 has a flat rectangle interface and plugs into a hub or USB host to send and receive data and power, respectively. An example of a type A USB connector is one seen on a keyboard or mouse. Type B USB connectors are square and have rounded corners on the outside. An external connection, such as one from a printer, connects it to an upstream port on the computer’s network interface card. Additionally, the type B connector transmits and receives data while also delivering power. Type B connections are sometimes solely used as power connectors and don’t have a data connection.


With the advent of the Micro-USB and USB-C cables, previous connectors have been phased out in favour of the newer, faster ones. In most cases, Micro-USB cables are used for charging and transferring data between cellphones, video game controllers, and a few computer peripherals like printers. There is a shift underway in the Android ecosystem, with micro-USB ports steadily being phased out in favour of type-C interfaces.


An Intel computer architect, Ajay Bhatt, co-invented and established the USB. When the USB was first announced in 1994, seven firms were involved in its development. These included Intel, Compaq, Microsoft, IBM, Digital Equipment Corporation, Nortel, and NEC Corporation.


Their goal was to reduce the number of connectors and simplify the process of connecting peripheral devices to a PC. Larger bandwidths were created by optimising software settings and eliminating difficulties with current interfaces’ use.


There is a USB Implementers Forum (USBIF) made up of companies that support and promote the USB standard. Besides marketing, the USBIF also looks after the specifications and enforces a compliance programme. The 2.0 revision of USB specifications was released in 2005. When the USBIF issued the standards, they were backwards compatible with previous versions of the USB protocol such as 0.9, 1.0, and 1.1.


Hot switching is one of the USB’s best characteristics. By using this capability, a device can be uninstalled or replaced without having to reset the system beforehand. For a long time, installing or removing a new device necessitated restarting the PC using an older port.


An unintended electrical current that might cause catastrophic harm to sensitive electronic equipment such as integrated circuits can be prevented by rebooting the device.


In the event of a hardware failure, hot swapping will continue to function. Hot-swapping specific devices like a camera, on the other hand, should be done with caution because a single shorted pin might cause damage to the port, camera, or other devices.
