  2. Hubs are used to connect multiple computers together • Broadcast same message on all ports (less secure) • This device would be used for: • Creating a private network • Transferring data to another computer • Decent 8 port hubs range from $49.99 to $90.00 HUB

  4. A switch is better than a hub by: (layer 2 device) • Only sending a message to the device that requested it • Also allow fiber connection link • Send Info faster • Switches are used in offices and homes for day to day work. • Depending on the ports, switch could cost from $10 to $200 Switch

  5. Routers allow computers to connect together and also allow for connection to the internet. Routers can be found with built in modems so you can get a 2 in 1 device. • Routers can be found in any environment • Wireless routers can cost between $20 to $200 Router

  6. A bridge works by creating a connection between two separate computer networks or the divide one network into two. Both networks use the same protocol. • Principle function is to forward data based on the MAC address of the sending and receiving devices • Device may be used when you have two networks and you want to be able to exchange information between the two • Price range is $45 to $150 Bridge Bridge

  7. A Gateway is used to connect two networks on different subnets (255.255.0.0) • These are mostly used in corporations with large networks that need to join their different subnets together • Range from $40 to $1000 Gateway

  8. A firewall blocks packets from entering your network • Rules must be set to drop packets that are not allowed in • Example “adapter A ipsrcaddr192.168.1.147 dstaddr any tcpsrc port 20 dst port 80” • Firewalls are usually built into some routers so households will have them. Dedicated hardware firewalls will be found in corporations • Price range is $120 to $5000+ Firewall

  9. Wireless AP plug into a switch/hub and broadcast wireless signal to wireless devices • AP’s need to be configured properly (security wise) to prevent unauthorized access • You can find AP in a lot of businesses that offer free Wi-Fi and homes will have them. Typically routers will offer built in Wi-Fi so an AP will not be needed • Price range is $20 to $200 Wireless AP
