Default how to set up a network?

hi, my name is dan and i am new here. i am very interested in getting into networking computers and administrating them ect.
although i have always had an interest i can never seem to do anything correctly.
i want to set up a network between my laptop in my room and the main pc downstairs. i like the network cable idea best but i have heared that you have to connect this to a central hub, how much would this cost me? not only that but i would like to ask: as i have a password protected account does that definetly mean that no-one else can access my files unless i want them to?
any help appreciated, many thans
dan

Welcome to CF man!

To answer your question, the hub is called a router, sharing your internet connection. If you have a passwordto acess the internet, you will NEED to install the application so the user or you could put in your username and pass.

well, I'd personally take a wired router. Now, for awired router, perpare yourself for $30-60, depending on what you buy. Next, go to ANY computer stores or places such as Best Buy, Future Shop, The Source...you know what I mean. Also, by some Ethernet wires, you'll need them

if it is, do you mean for me to use the many ethernet cable sockets at the rear of the unit or the signal itself? i wish to use the ethernet cable idea, not the wireless idea.
*also* does this mean that all of the computers must be on all of the time and that i can log on to my account from my downstairs pc?

Whoooo there...
hold on a minute...

if you only want to connect 2 pc's then the cross over cable that you heard about is a good idea.

but I can understand why you might like to do it properly... however this does not necessarily entail a router!!!

You were right in your first post the equipment that you require is called a hub.

for the purpose of connecting 2 pc's there is no need for a switch, and definitly no needfor a router!

Firstly...
How the cross over cable works...

In the network socket there are two lines, (well theres four actually but 2 are unimportant for this).

One is send (Tx) and one is recieve (Rx)
all a cross over cable does is swap these about so that the send of the first computer is conected to the recieve of the second, and the recieve of the first computer is connected to the send of the second,

ie
Code:
     ----------
Tx(A)-----\  /-----Tx(B)
-              X
Rx(A)-----/  \-----Rx(B)
(the X is the cross over!)

A hub is a little more complex, but basically the same,
in all the hub is basically a dumb piece of hardware, it listened for tramsmission (Tx) signals on all the ports it has, and when it recieves one it copies that signal to all of the recieve ports of the machines connected to it.
a hub will (usually) let you connect more than two pieces of hardware to it, and so can be used for sharing an internet connection if you have a modem with a network socket on it, or if you have a USB modem and need another computer to connect to the internet, also a hub can be used to share files and printers.

Next a switch...
a swith is basically an intelligent hub, it listens to all the transmission signals, but instead of repeating what it hears to all the devices attached to it, it only repeats it to the device that needs to have the information.

(Imagine how much slower your network is if someone downloads a 3GB file and all the bits of the file are sent to every computer on a hub (subsequently ignored), but still clogging up bandwidth!



Next routers, (and specifically why you don't really need one).
Routers can be thought of as super intelligent pieces of equipment, and usually have either a dumb hub, or switch attached to them.
Routers are normally used to conect to the internet, or to connect different nodes of the internet, the job of the router is to monitro traffic activity as information is sent through different nodes on the internet and try to determin the best route for the data to travel... (hence the name router!)...

However since you are only talking about using two machines, what exactly is a router going to decide? how will it improve your situation?, I see little point of you investing in a $60 router, when a $10 hub would suffice just as well..


Lastly, accessing your files, only those files that are actually shared are acessible, but that is not to mean that you don't have some hidden shares you don't know about...
to find out what shares you have on your machine open the command prompt and type

net share

a $10.00 you say, so that would work out to be around £6.70 i think. wow!
problem: the computers are on different floors and although the cable is not a problem, i am worried about the data transfer over the cables. i know that there is a aximum length of 5m for a usb cable so is there a max length for a network cabl? if so what is it please?

edit: not to mention my sis may also get a laptop soon so i want to easily be able to add computers to it

Actually there is a max length of 100meters on cat5 cables(network cable) but I don't think that will be a problem inside of your house.

a that is very good! i was going to get some cheap 'cat thingy 5' cables and they are only about £5.00 for quite a length i think. these are the patch ones used for use with a hub, i need a hub as my sis is gonna get a lapto soon too.

If you a your sister need internet access you're better to get a router than a hub because the process of accessing the internet with a router in much easier. With the hub you'll be getting into ICS (internet connection sharing) and if your ISP give you only one IP address you'll possibly need a second network card....so if I were you I'd buy a router to make things easier.

Default Re: how to set up a network?

the maximum length for a cross over cable ( or any ethernet (cat5)) cable is roughly 100meters,

If you want to share the internet then a router probably is best, unless you already have a router based modem these can be expensive to buy.

There is a chance that you might have a regular modem with a network adapter, and you need a computer to sign in... your modem may have the choice of Ethernet or USB.
in this case, I suggest (as a cheap option), rather than buying an 80 quid router go and grab a freetalk box from dixons, this only costs about 20 quid and can be used to sign onto the internet, combine this with the cheapest ethernet hub you can find and you've got an 80 quid router for about 30 quid, (that's what I do),

my setup is Telewest modem, connect via Ethernet to a freetalk box, which is connected to a hub,
The free talk box has built in firewall, DMZ, Routing, DNS and DHCP server.
oh and it's also a phone, with a low cost subscription and a free to any UK landline phone!

I would prefer gettting a wireless router anywayz. Most routers are set up to be DHCP server so they will hand out IP addresses to computer automatically. Other wise if you have just a hub/switch you would have to manually assign IP address to each computer in order for them to see each other.

Sure the router will cost more but it could actually make life a little easier. Just remember that if you do get wireless that you read your owners manual and lock down the router with a WEP key so only those who know the key can access your network!!!

ahh... the beauty of networking.
