the default, if you do not specify a port, is port 80
just to check.. I googled for http url syntax, and got the RFC
fortunately. They document the internet standards.
RFC 1738 says
An HTTP URL takes the form:

the standard is that Web/HTTP Servers run on port 80.
so Web/HTTP clients have no choice.
But they may use other ports, for security. To hide a bit!

I think any port between 1-65535 is ok..
There is a convention that the lower ones. 1-1024 are for servers, and
the higher ones, 1035-65535 are the random type clients use at their
end after making a connection to a server at its port.
If you run the command netstat -an then you see.

Only if there is a web server running on port 3863, which is not going
to happen, unless you happen to know that there is. Because you or
somebody you know put it there and told you he had.

running a web server on a port people do not expect, would hide it
it's not really up to the client to decide what port is used. The
server runs on whatever port, and the client has to connect to that
port to access it.

since the port is a TCP port, the subject is TCP/IP,
there is a book by Wendell Odom called Networking first step.. That is
And one by Que called "using tcp/ip"..
A good idea is to set up clients and servers, and then you will
understand.. That is very simple to do..
a web server.. A simple one is BRS WebWeaver.
an FTP server, a simple one is BP FTP..
more advanced web servers, people tend to use! are squid. or apache.
More of a pain to set up.. Hence I mentioned the simpe ones. Ideal to
get the hang of ports.
a very simple FTP server that is good, is quick n easy FTP.. though
it may be slightly crippled..
set these things up on your LAN, so all behind your router.. So you
don't have to set your router.
see them running with netstat -an,
try tasklist (or task manager.. processes, view PID) and netstat -
aon see the process IDs relate to processes.

People do not tend to learn the things you have mentioned as
theory.. , they run into them in practice. And that is why they are so
badly explained on the web.
People typically have to forward a port if they are running a server.
So eMule is a great example.. it sets up servers and requires port
forwarding. You will see many sites on how to get port forwarding
running so eMule will work.
VNC is another one but people setting that up tend to be techies.
eMule has more idiot users so the explanations associated with it will
Even SSH and tunneling.. When I tried to figure it out, I found the
explanations on the net were CRAP.. but by messing around with it I
got it to work.. Similarly, a program called PCHelpWare.. It has a
forum, which is good, and one can search that.. But the program itself
was completely unintuitive, I figured out how it worked by clicking
the buttons and seeing what effect they had..
People generally cannot communicate.. And instructions are often crap.
They are a good guide though..
You will at least know what to experiment with..
Of course, instructions relate to a program. They are not theory.. I
just google around to read theory.. none of it is greatly explained,
but if you look at many many websites, then you can reconcile it..
Really though, the theory is not well explained enough, and therefore
you only really learn the theory by doing the thing in practice.
And the concepts you have mentioned, are things people have run into
in practice.. And the only things they read, were instructions.. And
they figure out what does what like a kid figures out a video machine.
Try things and figure out what happens and build up an understanding
of how it works.. And instructions can be a good guide...
or can even answer some problems!

if you are dumb then it may be for other reasons that you have not
shown. But it's not visible from anything you wrote here.
