USB

USB, or Universal Serial Bus, is a standard for connecting devices to computer systems and enabling communication between them. It defines the specifications for cables, connectors, and protocols used for data transfer and power supply. USB allows a wide range of devices, including keyboards, mice, printers, external storage, and smartphones, to connect to computers and other peripherals.Introduced in the mid-1990s, USB has evolved through various versions, such as USB 1.0, USB 2.0, USB 3.0, and the latest USB4, each offering improvements in data transfer speeds and capabilities. USB connectors come in different types, such as Type-A, Type-B, and Type-C, with Type-C being the latest and most versatile design, supporting reversible connection and higher power delivery.USB's universal nature has made it a standard interface in many electronic devices, simplifying the process of connecting and powering devices while also promoting compatibility across different manufacturers and technologies.
