2. Hub
A hub is an Ethernet hub, active hub, network hub, repeater hub, multiport repeater or hub. Is a device for connecting multiple Ethernet devices together and making them act as a single network segment. Prices varies form $35 to $400 depending on brand use and bandwidth.

3. Router vs Switch
The functions of these two devices are quite different from one another, even at times the two are integrated into a single device.
Switch: Filters and forwards packets between LAN segments.
Routers: Forwards data packets along networks.
Routers cost varies from$70 to $4000 depending on brand and use.

4. Bridge
The bridge is a product that connects a local area network (LAN) to another local area network that uses the same protocol of example, Ethernet or token ring. In the diagram shown below, data from Computer 1 and Computer 2 is still capable of colliding.

5. Gateway
In telecommunication networks, a gateway is a network node equipped for interfacing with another network that uses different protocols. Gateways prices varies from $200 to $10,000 depending on brand and use.

6. Firewall
A firewall is a system designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software or combination of both.

7. Wireless AP
Wireless Access Point (AP) is a special purpose communication device on wireless local area networks (WLANs). Access points act as a central transmitter and receiver of wireless radio signals. Aps support Wi-Fi and are most commonly used to support public internet hotspots.
