What is the purpose of USB?

The purpose of USB (Universal Serial Bus) is to provide a common interface for connecting a wide variety of devices to computers and other electronic devices. This standardized connection method facilitates communication and power supply between peripherals such as printers, keyboards, mice, and external storage devices, among others. By establishing a uniform protocol, USB simplifies the process of connecting devices, ensuring they can be easily recognized and used regardless of the manufacturer.

In addition to its role in data transfer and power supply, USB has evolved over the years to include improved data transfer speeds and support for multiple devices through hubs. This versatility is fundamental to its widespread adoption in various technologies and consumer electronics.

While enhancing internet connectivity, storing data securely, and compressing files for easier sharing are important aspects of technology, they are not the primary functions of USB. USB specifically serves as a standardized solution for connectivity between devices, making it a crucial component in modern computing and device interoperability.
