How the Internet Works
What happens from the moment you type an address in your web
browser to the moment that your content is generated?
Source: https://www.helloitsliam.com/2014/12/20/how-the-internet-works-infographic/
When you type in a URL, like
community.mis.temple.edu/schedul
e – what you’re actually saying is “I
want to use HTTP to access the
world wide web and find a set of
domains called
community.mis.temple which are
part of a top-level domain called
.edu and once inside that domain I
want to locate a particular file or
page called schedule.
Your teacher’s third grade
sketch:
This is a simplified view of
what happens when you
make a request for web site.
In reality, there is a lot more
going on. There are multiple
layers of firewall, for
example. A request might go
from a router to a modem
to the ISP. A request might
be routed through a proxy
server. There are many
permutations, but this is the
general idea.
