Usb Communication Protocols
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
USB communication protocols refer to the standardized methods and procedures that enable data transfer between computers and peripheral devices via Universal Serial Bus (USB) interfaces. These protocols define how devices identify themselves, communicate, negotiate speeds, and transfer data efficiently and securely across various USB versions (e.g., USB 2.0, 3.0, 3.1, 4.0). They underpin a wide range of peripherals including keyboards, mice, storage devices, cameras, and more.
