Explanation:
Hub:
Active hub and passive hub are two types of hubs. ... Hubs differ from repeaters in that they do not boost the incoming signals and are designed for multiple input lines, but the differences are slight. Like repeaters, hubs are physical layer devices that do not examine the link layer addresses or use them in any way.
Switch
switch is a multiport bridge with a buffer and a design that can boost its efficiency(a large number of ports imply less traffic) and performance. A switch is a data link layer device. The switch can perform error checking before forwarding data, that makes it very efficient as it does not forward packets that have errors and forward good packets selectively to correct port only. In other words, switch divides collision domain of hosts, but broadcast domain remains same.
Modem
A modem is an electronic device that converts digital sign for computer into an anlog form so that they can travel into a phone line.At the destination,the reciving modem converts the anlog signals into a simple form.
