Describe active and passive hubs.
What will be an ideal response?
A hub is a generic connection device used to tie several networking cables together to create a link between different stations on a network. Most hubs are plugged into electric power and are active hubs. They usually amplify or repeat signals that pass through them, similar to repeaters. Because they have multiple inbound and outbound connections, these hubs are also known as multiport repeaters. A hub that merely connects cables on a network and provides no signal regeneration is called a passive hub and is not a repeater.
