USB (Universal Serial Bus) was introduced in 1996 to standardize connections between computers and peripherals, evolving through multiple versions to become a universal standard for data transfer and power delivery.
Introduction and Development
Origins: USB was developed in the mid-1990s by a group of companies including Intel, Microsoft, and others, aiming to simplify the connection of peripherals to computers. The first commercial version, USB 1.0, was released in January 1996, offering a data transfer rate of 12 Mbps.
Early Adoption
The Apple iMac G3, released in 1998, was the first computer to feature only USB ports, which helped popularize the standard.
Evolution of USB Versions
- USB 1.1: Released in August 1998, this version improved compatibility and performance, leading to widespread adoption of USB devices.
- USB 2.0: Launched in April 2000, USB 2.0 increased the data transfer rate to 480 Mbps, enabling faster connections for devices like flash drives and external hard drives.
- USB 3.0: Introduced in November 2008, USB 3.0 significantly boosted transfer speeds up to 5 Gbps, allowing for quicker data transfers and more efficient power delivery.
- USB 3.1 and 3.2: Released in 2013 and 2017 respectively, these versions further increased speeds (up to 20 Gbps) and introduced the USB-C connector, which is reversible and supports higher power delivery.
- USB4: Announced in 2019, USB4 supports data transfer speeds of up to 40 Gbps and integrates Thunderbolt 3 protocols, allowing for even greater versatility in device connectivity.
- USB4.2: was introduced with the ability to support speeds of up to 80 Gbps over USB-C.
Future development of USB-C
USB type-c is the standard port that could be competent to transmit all kinds of data specification without losing speed and transmission quality.
USB Type-C is the final revolution of data transmission. Its deepest meaning is that in the future Type-C will unite all kinds of ports standard. You could use only one cable to charge your phone, connect your computer with monitor, link your phone and PC to transmit data, etc.
