Model Train Bridge
IT can help with one or two questions?
I'm IT training. Actually, I'm in college studying to be a network administrator. In this time, all acronyms are still rather confused. Diffetert know network protocols and devices operating at different levels in the OSI model. Di theorreticaly, I was doing LAN hybrid star. When you create the bridge? When using a bucket in front of a switch. Where do I put the routers (other than in the Gateway and borders? In short, I'm trying to get a handle on these network devices. Thanks for any help you can offer.
First, we do not call your doctor. That's like saying "I am a science" instead of "I am a scientist." IT is the field you are entering, not the title that is earned. A network bridge connects two (or more) network segments. In some ways it is as a router, except for a bridge operates at OSI Layer 2 (data link), while a router operates at Layer 3. The bridge directs packets based on MAC addresses. Armies in the bridge segments can be on the same IP network, but are in different collision domains. One site I maintain has several buildings on a campus of 26 acres. I use a bridge [wireless] to turn a building without physical uplink to the rest of the network. These days, the only time I'd use a hub (rather than a switch) is protocol analysis. A hub is basically a multi-port repeater, which makes it useful for inspecting network traffic. Otherwise, they are almost obsolete, except for a few obscure applications. A router is required whenever hosts on different networks you want to talk to each other. Apart from the walkways and borders, using a router to connect divergent segments within a broader Intranet or for a segment of network traffic and control between their armies.
