Hubs were once the go-to devices for connecting multiple computers and devices. While still found in some very basic setups, their limitations have led to their decline in popularity compared to more sophisticated solutions like switches. Here's a closer look at hubs
Function:
Hubs act as central connection points for devices in a network. They receive data packets from any connected device and simply broadcast them to all other devices on the network. Functionality:
Unlike switches that can learn and intelligently direct data, hubs operate at a much simpler level, functioning like repeaters. They lack the ability to differentiate between devices and simply amplify and resend any received signal.
Limitations:
Inefficiency: Due to broadcasting, hubs can significantly impact network performance, especially as the number of connected devices increases. Every device receives all data, regardless of whether it's intended for them, leading to unnecessary traffic and potential collisions.
Security concerns: Broadcasting data to all devices can pose security risks, as sensitive information might be exposed to unauthorized devices on the network.
Limited scalability: As the network grows, adding more devices to a hub can quickly lead to performance degradation and congestion.
Use cases:
While largely obsolete in modern networks, hubs might still be found in very basic setups with a limited number of devices where simplicity and low cost are prioritized over performance and security.
Comparison to switches:
Switches offer significant advantages over hubs:
Improved performance: By intelligently directing data only to the intended recipient, switches significantly reduce network congestion and improve overall performance.
Reduced collisions: Full-duplex operation in switches eliminates collisions that can occur in hubs when multiple devices attempt to transmit simultaneously.
Enhanced security: By not broadcasting data to all devices, switches offer a layer of security by limiting the exposure of sensitive information.
While hubs played a historical role in the early days of networking, their limitations have rendered them largely obsolete in favor of more advanced and efficient solutions like switches
