A USB or Universal Serial Bus port allows you to connect various peripherals to a computer.
The Universal Serial Bus or Universal Serial Driver is a type of port created in 1996 by a conglomerate of seven companies. These include IBM, Intel, Northern Telecom, Compaq, Microsoft, Digital Equipment Corporation and NEC.
A USB port works as a device that facilitates the connection of peripherals and accessories to a computer, allowing easy exchange of data and the execution of operations. Typically, devices that use USB can be keyboard, mouse, printer, mobile phones, photo or video cameras, external hard drives, media players, sound and video cards, scanners, and a variety of others.
For its use, it is sometimes necessary to install software that helps the computer recognize the new device and use it at its discretion. In other cases, they are called “plug-n-play”, that is, just by plugging them in, the device with a USB port is already up and running and connected to the computer.
Most USB devices also include an electrical transmission standard that allows them to obtain a power supply while they are connected to a PC or computer.
This type of port has grown widely in popularity because it is easy and cheap, and it saves time and cost when, for example, you have many peripherals that are frequently connected to a computer. At the same time, all computers on the market usually have one or more USB ports to allow multiple devices to be connected at the same time. In this way, a user can connect not only mouse and keyboard, but also cameras and mobile phones for data exchange. Another case, in addition, is the one that allows information to be transferred to hard drives or external memories, freeing up space in the computer’s fixed memory and transporting this data to other computers.
