Switch (Multiport bridge) Layer 2 device that implemented the same functionality of a bridge, but instead of operating based on software implemented the frame switching process in hardware (basically making a switch much faster). A switch has more than two ports, unlike a bridge.
Cisco Network Devices
Repeater This layer 1 device was designed to propogate signals that would typically degrade due to attenuation. It has two ports and repeats bits.
Hub (Multiport Repeater) Layer 1 device that functions exactly like a repeater. The one core difference is that a hub contains more than two ports.
Bridge Layer 2 device that was created to cut down the size of collision domains. Instead of just repeating bits, the switch forwards frames between network segments.
Router Layer 3 device that connects network segments together. The primary function of the router is to switch packets and select a best-path for packets to follow to arrive at a particular destination. The router is what makes the Internet possible.
Wireless Router The wireless router operates in the same fashion as a regular router, except it adds a wireless interface.. The wireless router still switches packets based on IP addresses.
Network Cloud A network cloud represents layers 1-7 and is designed to show in a generic fashion large networks without having to specifically draw every device that is part of that network.
Host (Computer) Layers 1-7, this symbol represents a single computer on a network. The end-point of communications.
