  3. Hub Hubs are used to connect a computer to multiple computers on a network.Hubs can be used in homes or in businesses of all sizes. Price ranges from $10-$50,000. This device sends data from one computer to all other computers on the network. It’s a low-cost, low function machine that usually operates at layer 1 of the OSI model and ties together the computers attached to it through multiple (twisted pair or optical) ports.

  4. Switch A switch is a device that channels incoming data from any of multiple input ports to the specific output port that will take the data toward its intended destination. Switches are used to set up a dedicated though temporary connection or circuit for an exchange between two or more parties.  Switches are used in homes, as well as businesses. The price ranges from $1,500-$60,000/

  5. Router A machine acting as a central relay point on a network. When data comes in on one of the lines, the router reads the address information in the packet to determine its ultimate destination. Routers are used in homes and small offices. The price ranges from $600-$200,000.

  6. Bridge A LAN device that connects network nodes. A machine acting as a central relay point on a star network topology using MAC addresses. Bridges are used when it is flooding and examination of source addresses in received packet headers to locate unknown devices. Bridges are used in businesses and companies. The prices range from $40-$1,500.

  7. Gateway A router on a TCP/IP network that serves as an access point to another network. A gateway is used to transfer between an access point to another networks. A gateway is used in homes and businesses. The price range starts from $1,500-$200,000.

  8. Firewall A security feature on a network that filters unwanted traffic from entering a network or a computer. Firewalls are used when using the internet to keep destructive forces away from your property. Firewalls are used in homes and large companies. The price range is from $300-$25,000.

  9. Wireless Access Point A device used to connect wireless nodes and relay traffic among these nodes. WAPs are used whenever there is a need for network connectivity. WAPs are used in homes and in businesses. WAPs price range start from $160 to $540.
