A USB port is a standard cable connection interface for personal computers and consumer electronics devices. USB stands for Universal Serial Bus, an industry standard for short-distance digital data communications. USB ports allow USB devices to be connected to each other and transfer digital data over USB cables
USB ports are one of the most commonly used hardware components on a Windows computer. They are used to connect external devices like flash drives, cameras, printers, and other devices to a computer. While USB ports offer great convenience, they can also be a security threat. A malicious user can use a USB device to introduce malware into your computer or steal sensitive information. As a result, it’s important to be able to control access to your USB ports.
In this blog post, we’ll explore how to enable and disable USB ports on Windows.
