COSC 85B PART 3

• - are the devices that interconnect networks.

• These devices are also known as connectivity devices, because they connect network entities

– operates at the physical layer.

• - Its job is to regenerate the signal over the same network before the signal becomes too weak or corrupted so as to extend the length to which the signal can be transmitted over the same network.

a multiport repeater.

these are devices to link several computers together.

A hub has no intelligence – it sends all data received on any port to all the other ports. I

– these are hubs which have their own power supply and can clean, boost, and relay the signal along with the network

these are the hubs which collect wiring from nodes and power supply from active hub. These hubs relay signals onto the network without cleaning and boosting them and can’t be used to extend the distance between nodes.

- It work like active hubs and include remote management capabilities. They also provide flexible data rates to network devices. It also enables an administrator to monitor the traffic passing through the hub and to configure each port in the hub.

A network device that connects two similar network segments together. The primary function of a bridge is to keep traffic separated on both side of the bridge.

is a multiport bridge with a buffer and a design that can boost its efficiency and performance

is a device like a switch that routes data packets based on their IP Addresses.

is the process of forwarding the packets from source to the destination.
