1. Complete the review questions:

a. Static routing is a technique in which a network administrator programs a router to use specific paths between nodes.

b. True or False: Bridges are protocol independent.

c. True or False: Repeaters operate in the Physical layer of the OSI model.

d. Firmware is a set of data or instructions that has been saved to a ROM.

e. True or False: A NIC has no room for a transceiver

Device | Functionality | Benefits | Requirements and Maintenance |

Hub | Hubs takes data from one port and send it out all the other ports in the hub. It does not perform any type of filtering. Hubs work at the physical layer of the OSI model. | The major benefit is cost, because the device is less complicated it is often cheaper. | Hubs are used on 10BaseT and 100 Base TX Ethernet network with more than two computers. An amplifier helps to ensure that the devices receive those signals. Hubs come in variety of sizes 12 – 24 ports. It is recommend that hubs or install in a cool room that is free of dust. |

Switches | Switches are like bridges. It forwards information based on the destination address in the packet. Switches operate at the data link layer of OSI model. | The major advantage is they isolate data on heavy networks. It also improves performance because it can handle a larger volume of data in transit at any given time. | Switches will need network cables to connect the computers. If you run out of ports of the switch then that is an indication that another is need to handle the size of the network, |

Router | Routers determine where to send information from one computer to another. It forward data packets based on their addresses to their destinations. Router operates at the network layer of the OSI model. | Routers ensure steady availability of network connectivity. It also provides integrated services of data, video and voice over wired and wireless...
