Switch 56, ISDN, DSL, Frame Relay

No

Big difference

Cable Internet

yes with VoFR

and e-mails?

Yes with Internet service

Either forget about all this definitions and just use available tecnnologies, or use Google or WikiPedia and become a "prodessional".

No, it's "Cable Modem" and nothing else.

Cannot afford forgetting these definitions, on the contrary, have to memorize all for an entry level exam. Tired of theory and memorizing, need to see or understand where and how do these things apply in real life ... Google and Wikipedia do not help either.

Thanks for the reply

Happy New Year

• Switch 56 is an early 90's digital hookup, the forerunner to today's ISDN network. Does not exist today.
• BRI stands for "Basic Rate Interface" (BRI, 2B+D, 2B1D) - ISDN) configuration consists of two 64 kbit/s "bearer" channels (B channels) and one 16 kbit/s "data" channel (D channel). It's today's ISDN lines.

are you sure about that?

Thanks, my question was about real life examples; i.e., if i subscribe to BRI, will my existing phone line be enough, or do I need other CPE ...

Again, you are missing the whole point of my question. Let me copy and paste it again: "... Tired of theory and memorizing, need to see or understand where and how do these things apply in real life ... Google and Wikipedia do not help either."

Thanks anyway.

If you read WHOLE article, you will learn, what's use for one or another technology in today's life. Most articles describe use of a technology, and if not - find another article, then another. Do your homework yourself, don't cheat... :-)
