Network+ 2005 6-2: Introduction to Internetworking
Question | Answer |
---|---|
Internetworking | The technology and devices by which computers can communicate across differing types of networks |
Segment | A portion of a network on one side of a network transmission device |
Backbone | A high-speed network link connecting two segments -This way, only packets whose destination another segment traverse the backbone |
MAC Addresses and Internetworking | MAC Addresses are used to determine the next hop that a packet takes on its route |
Repeater | A device that amplifies the electrical signal from one network cable and passes it to another -operates at Physical Layer -Used on baseband networks -Typically used on bus networks -Make the segments connected the same length for the best signal quali |
Amplifier | A repeater for broadband networks |
Repeater Problem Areas | -Signal Quality: Noise is amplified along with signal -Time delays: Greater distances to traverse can cause timeout errors -Network Traffic: Repeaters do not filter traffic -Node limitations: Repeaters don't create new segments |
