USB
USB (Universal Serial Bus) is an industry-standard technology for connecting peripherals to computers and other electronic devices, enabling data transfer and power delivery. It provides a standardized interface for devices like keyboards, mice, storage drives, printers, and smartphones, simplifying connectivity and reducing the need for multiple port types. USB has evolved through versions (e.g., USB 2.0, USB 3.0, USB-C) to offer faster speeds, improved power management, and reversible connectors.
Developers should learn USB technology when working on hardware integration, embedded systems, or device drivers, as it's essential for connecting and communicating with peripherals in applications like IoT, robotics, or consumer electronics. It's also crucial for debugging and deploying software on devices via USB connections, such as in mobile app development or firmware updates. Understanding USB helps ensure compatibility and efficient data/power handling in projects involving external hardware.
