Introduction to Wide Breadth Networks
So what, exactly, is it that makes article a
wide breadth arrangement (WAN)
instead of a local
area arrangement (LAN)? Well, there’s acutely the ambit thing, but these days, wireless LANs
can awning some austere turf. What about bandwidth? Well, actuality again, some absolutely big pipes
can be had for a amount in abounding places, so that’s not it either. So, what the heck is it then?
One of the capital means a WAN differs from a LAN is that while you about own a LAN
infrastructure, you usually charter WAN basement from a account provider. To be honest,
modern technologies alike becloud this definition, but it still fits neatly into the ambience of Cisco’s
exam objectives.
Anyway, I’ve already talked about the abstracts articulation that you usually own (Ethernet), but now
you’re activity to acquisition out about the affectionate you usually don’t own—the blazon best generally leased
from a account provider.
The key to compassionate WAN technologies is to be accustomed with the altered WAN
terms and affiliation types frequently acclimated by account providers to accompany your networks
