1: Passive Hub
A passive hub is a basic network device that allows multiple devices to connect to a network. It serves as a central point for connecting devices, but it does not amplify or regenerate the signals it receives. Its main purpose is to provide a physical connection between devices, acting as a junction box. The uses of a passive hub include:
- Connecting multiple devices to a network: A passive hub allows multiple devices, such as computers, printers, or switches, to be connected to a network using Ethernet cables.
- Expanding network connectivity: By connecting devices to a passive hub, you can expand the number of devices that can be connected to a network.
- Cost-effective solution: Passive hubs are relatively inexpensive compared to other network devices, making them a cost-effective option for small networks or temporary setups.
2: Active Hub
An active hub, also known as a multiport repeater, is an enhanced version of a passive hub. It not only provides a physical connection between devices but also amplifies and regenerates the signals it receives. The uses of an active hub include:
- Signal regeneration: Active hubs regenerate weak signals, ensuring that the data transmitted between devices is not degraded over long cable distances.
- Signal amplification: Active hubs amplify signals, allowing them to be transmitted over longer distances without loss of quality.
- Network expansion: Active hubs provide multiple ports for connecting devices, allowing for network expansion and accommodating more devices.
- Collision detection: Active hubs can detect collisions on the network and help manage network traffic by implementing collision detection algorithms.
- Network troubleshooting: Active hubs often have diagnostic features that can help identify network issues, making them useful for troubleshooting network problems.
It is worth noting that both passive and active hubs are considered outdated technologies and have been largely replaced by switches, which offer more advanced features and better performance.
