1. what is the difference between a hub and a switch

While they have often been used as a quick and easy way to connect a small network, they are becoming increasingly replaced by switches. Switch A networking switch is a type of hardware that uses packet switching to receive and forward data to its intended destination within a network. Essentially, a switch is a more efficient, more intelligent version of a hub.

Perhaps the biggest difference between a hub and a switch is the way that it delivers data packets. Rather than blindly passing along data to all devices in a network, a switch records the addresses of the connected devices. With this information, a network switch can identify which system is sitting on which port. So when a frame is received, it knows exactly which port to send it to, without significantly increasing network response times. So regardless of the number of PCs transmitting, users will always have access to the maximum amount of bandwidth.

Unlike an Ethernet hub or switch that is concerned with transmitting frames, a router is to route packets to other networks until that packet ultimately reaches its destination. One of the key features of a packet is that it not only contains data but the destination address of where it's going.

What's more, router is the only one of these three devices that will allow you to share a single IP Internet Protocol address among multiple network clients. You can have a clear view of the comparison among hub vs switch vs router here:.
