A USB or Universal Serial Bus port allows you to connect various peripherals to a computer.
The Universal Serial Bus or Universal Serial Conductor is a type of port created in 1996 by a conglomerate of seven companies. Among them, IBM, Intel, Northern Telecom, Compaq, Microsoft, Digital Equipment Corporation and NEC.
A USB port functions as a device that facilitates the connection of peripherals and accessories to a computer, allowing the easy exchange of data and the execution of operations. Typically, devices that use USB can be a keyboard, mouse, printer, mobile phones, photo or video cameras, external hard drives, media players, sound and video cards, scanners, and a variety of others.
Its use sometimes requires the installation of 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, by simply plugging them in, the device with a USB port is already in operation and connected to the computer.
Most USB devices also include an electrical transmission standard that allows them to obtain a power source while being connected to a PC or computer.
This type of port has grown widely in popularity because it is easy and cheap, and contributes to saving 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 transferring information to hard drives or external memories, freeing space in the fixed memory of the computer and transporting this data to other computers.
