Can anyone tell me what a hardware router is? and with a firewall?

Routers have been around for a long time - mostly as appliances (boxes
that are self-contained with a single purpose).

Routers that you find in the computer stores now are NAT Appliances that
act as one-way filters for your internet connection.

Most "Home/SOHO" firewall appliances are really just NAT Routers that
provide protection against unsolicited inbound intrusion, but they do
very little (if anything) to stop outbound traffic.

For most home users, a NAT Router is the minimum you would want
installed to protect your computer/network, and it's a very good idea to
have one if this first, then, if you feel you need it, a personal
firewall application running on your computers.

Search google for more info.

I used to use a hub to share the pcs on my home network. Now I use,
what's called a "router". It does the same as a hub, but hides the
internal IP addresses [firewall].

Simpler than a router is a hub. That is roughly like one of those
power strips, where you can plug half a dozen different cords into
the strip and power gets sent to all of them. A hub is like that,
two or more computers with ethernet cards get plugged together via
the hub and it is as if they are all wired directly together, every
computer watches all the messages from all the others, every
computer sends messages to all, and each computer has to sort out
which ones are for it.

Next step up in complexity is a switch. If you have A talking to
B but C doesn't need to hear this, a hub sends everything to A,B,C.
But a switch can connect A to B automatically and C won't have to
spend time looking at all the traffic that isn't for it. And the
switch automatically figures out how to send messages back and
forth between the right pair of computers.

Next step up in complexity is a router. Routers can do everything
a switch can do. But they can also usually do some translation
on the messages, change addresses inside the message, change port
numbers inside the messages, maybe be set up to block certain
addresses, etc.

Firewalls stand guard. If there is a fire on one side they are
supposed to keep it from spreading through the wall to the other
side. So they look at all the messages hammering against the
wall and they just throw away "bad" messages, based on some set
of rules. Maybe you tell the firewall to never let Instant
Messages through, discard them instantly. Or maybe you tell it
to never let messages being sent to "wierd" ports through. Or
maybe you tell it that you will let http messages go out but not
let them come it. Those are sort of universal rules that you
choose up front. But there is a second kind of rules that some
firewalls can use. Perhaps your firewall will watch what you
send, if you send an http message out to some web site then the
firewall will watch incoming http messages and if it sees one
from some unrelated oddball web site it will throw it away, but
it will accept answering messages to the http message you sent.
Firewalls that do this sort of thing are said to have "state",
they remember what you have done, and in that particular state
they decide what to do next.

A HUB is way different than a Router, but a HUB is also different than a
SWITCH.

Your "Router" has a X port switch in it.

In general, unless the group name contains the word "binaries" it's not
polite to post files to the group. There are tons of methods to explain
a problem, only one of them includes posting a file to a non-binary
group.
 
Instead of knowing what a Router is may I suggest that you tell us
exactly what you are trying to do. If accessing your home network is
your main priority then I suggest get any ADSL wireles modem which has
evrything built into it.

ADSL modem will allow you to share files, printers and also access the
Internet via your broadband account.

Thanks for embedding the graphic file. My setup won't let me manually open
files attached. Not a complaint on my end.

In general yes, in the alt.* hierarchy of UseNet

One exception is in the Microsoft hierarchy ;-)

It was attached, not embedded as I used Plain Text to post.

No !

Modems do not. However a combination Router+Modem will. Be specific.

The rules/norms didn't change when Microsoft started learning that there
was/is an internet. Usenet was around before Microsoft learned about it,
and they've been trying to mold it to their ideals ever since - it still
doesn't make it right.

But Microsoft has the right to state what is or isn't allowed on THEIR server. I posted to
their server.
The alt.* hierarchy is one of many hierarchies. They exist for a reason. There are
didfferent rules for different hierarchies. There is no one rule that covers all
hierarchies in UseNet space. Additionally, the Microsoft hierarchy is different than the
rest of UseNet in that you can post to a master server which is replicated to UseNet space.

The Rules of Conduct http://www.microsoft.com/communities/conduct/default.mspx and all
statements on the use of this News Server don't disallow posting attachments so THAT is the
final word.

Yes, Dave, I know that MS has it's own server and has it's own charter
for groups that it created. But it doesn't change the simple norm that
they are one of the very few organizations that have taken the position
to violate the norms of Usenet. Had they really wanted to be a good
community member they would have created m.p.w.g.binaries so that those
of us that pull Usenet feeds don't have fetch binaries also.

It's kind of like their making OE work with Usenet and then not having
any way to educate users on proper usenet etiquette. Where most of the
good Usenet clients properly trim sigs, properly put the cursor at the
bottom, etc... You know what I'm talking about :)

I just don't think we should make exceptions for the likes of MS just
because they are MS, they should have followed the same norms as the
rest of Usenet and not tried to poison it.
