HUB A low cost device
that sends data from one computer to all others usually operating on Layer 1 of the OSI model.
Range from $10 to $150

Switch A device that relays
traffic by using Layer 2 address.
It usually contains software that supports the building of routing table.
Range from $10 to $2,500.

Bridge Like a Switch it
relays traffic, but with a LAN device.
Ranges from $50-$300

Router They operate on at
OSI Layer 3 with IP addresses.
High-end routers can also be configured to as firewalls and extensive network management features.
Range from $50 to $1,500

Firewall A security feature
on a network that filters unwanted traffic from entering a network computer.
Range from $300 to $3,000.

Gateway The activities of a
gateway are more complex than that of the router or switch as it communicates using more than one protocol
Can operate at any network layer
Range from $100 to $300

Wireless AP A device that allows
wireless devices to connect to a wired network using Wi-Fi, or related standards.
The AP usually connects to a router (via a wired network) as a standalone device, but it can also be an integral component of the router itself.
Range from $20 to $100
