USB Hubs have revolutionized the way we connect multiple peripheral devices to our computers. The Universal Serial Bus (USB) was developed in the mid-1990s to simplify and standardize the connection between computers and peripheral devices such as keyboards, mice, printers, and storage devices. The first USB specification was released in 1996, with the subsequent introduction of USB hubs that quickly followed to address the increasing demand for more USB ports.
Types/Categories
Passive USB Hub
A passive USB hub draws power from the computer’s USB port and doesn’t require an external power source. This type is suitable for low-power devices like mice and keyboards.
Active USB Hub
An active USB hub, also known as a powered USB hub, comes with its own power adapter. It can provide additional power to connected devices, making it suitable for power-hungry peripherals like external hard drives or multiple charging devices.
USB 2.0 Hub
USB 2.0 hubs support a transfer rate of up to 480 Mbps and are compatible with USB 1.1 and USB 1.0 devices.
USB 3.0 Hub
With a transfer rate of up to 5 Gbps, USB 3.0 hubs are significantly faster than USB 2.0 and are backward compatible.
USB-C Hub
USB-C hubs feature the latest USB connection standard, offering high transfer speeds and support for modern devices. They can also transmit video signals and power simultaneously.
Key Events
- 1996: Release of the first USB standard.
- 1998: Introduction of USB hubs to expand connectivity options.
- 2008: Launch of USB 3.0, significantly increasing data transfer speeds.
- 2014: USB-C standard released, promoting universal connectivity.
Detailed Explanations
USB hubs act as extensions that allow multiple devices to be connected to a single USB port. They manage the data flow between the computer and the connected peripherals, ensuring efficient communication and power distribution.
