What network hardware will be required to replace the hub in order to improve network performance ?

To improve network performance, replacing the hub with a switch would be the ideal solution. A switch is a more advanced networking device that can handle data traffic more efficiently by directing data only to the intended recipient, unlike a hub which broadcasts data to all connected devices.

In addition to a switch, other network hardware that may be required to improve network performance include:

1. Ethernet cables: High-quality Ethernet cables are essential for ensuring fast and reliable data transmission between devices.

2. Network interface cards (NICs): Upgrading NICs in devices can also help improve network performance by providing faster data transfer speeds.

3. Router: A router is necessary for connecting multiple networks and managing data traffic between them. Upgrading to a more advanced router can help improve network performance.

4. Access points: If you have a wireless network, adding access points or upgrading existing ones can help improve wireless coverage and speed.

5. Network cables and connectors: Using high-quality network cables and connectors can also help improve network performance by reducing data loss and interference.

Overall, replacing the hub with a switch and upgrading other network hardware components can significantly improve network performance and efficiency.
