Mike talks about DSL, how it’s used, and some of the characteristics that have been applied to access the Internet.
- Digital Subscriber Line, or DSL,…was one of the original broadband technologies…to get high-speed internet to the premises.…Now, DSL lives on telephone lines.…And in my opinion, it's kind of dated.…So let's put some sepia tone up here, right?…Just fade it out, alright, that looks a little bit better.…DSL has been around since, arguably,…the late 80's, early 90's.…And pretty much nobody, oh wait a minute,…kill the sepia, guys, let's bring it back up.…
A lot of people still use DSL.…And it's also on the exam, so I wanna take a moment…and go back in time a little bit,…I had to pull some stuff out of the vaults here,…to talk about DSL.…So DSL comes from telephone companies.…So a telephone company would provide…a special DSL-capable line.…This was the same line that your telephones were on.…Remember when telephones were hooked on RJ-11 cables?…And what you would do is, you would plug into…your wall jack, you would plug into one of these.…
This is a DSL modem, circa 1998.…Now what I want you to do is, take a look on the back here.…
