USB Definition

USB (Universal Serial Bus) is an industry-standard technology for connecting peripherals to computers and other devices. It supports data transfer and power supply over a single cable, with multiple versions such as USB 1.0, 2.0, 3.0, and USB-C. USB technology simplifies hardware communication, enabling plug-and-play capability across devices like keyboards, mice, storage drives, cameras, and smartphones. It also supports hot-swapping, allowing devices to be connected and disconnected without shutting.

USB Explained Easy

Imagine a magic cable that connects your computer to many devices like a mouse, keyboard, or even your phone, making them talk to each other. You don’t need to worry about plugging it in perfectly or restarting your computer. That magic cable is called USB, and it helps devices share information and power easily.
