    some crazy questions coming into my mind:twisted: :twisted:

    first one : do we need routers for LAN setup ? if
    when?


    second one : for ex. we are working in a firm and
    have some routers and the weird thing is coming

    frame relay , isdn are WAN types so how do we configure
    them in LAN because they are WAN types?


    (i mean WAN IS CONNECTING LANS so HOW CAN THIS BE?)

    third one : a simple question
    we wanna build LAN and givin IPs for pcs and
    they will be at same network ,when we have a file sharing
    between two computers in this LAN , why don't we
    connect with cable the two pcs?

    Depends. In a very simple situation - no. In more complex situautions where different network types meet - then yes.

    You use special types of routers to enable Frame Relay and ISDN to talk to an Ethernet LAN

    Using the router.

    You do. All the devices on the network will usualy be connected to a switch to allow them all to talk to each other. This switch *may* be connected to a router to allow the network to talk elsewhere. In some case the switch may be physicaly part of the router.

    If you just want to share files etc between two PCs, you can indeed just use a cable *but* that cable would need to be a 'crossover cable'.

    You could connect 2 pcs through a crossover cable however this type of network is not very useful especially in an office environment.

    You might use a router in a LAN to route between different VLANS if you aren't using a multilayer switch in your core/mdf.

    I would suggest buying a copy of the following books:
    CiscoPress Computer Networking First Step
    CiscoPress LAN Switching First Step
    CiscoPress Routing First Step

    http://www.ciscopress.com/index.asp?rl=1

    These should help you out with some of the backgroun as to why you might want to build a computer network versus using direct PC to PC communication.

    for second one i ask again

    for ex. we are working in a firm and
    have some routers and the weird thing is coming

    ! frame relay , isdn are WAN types so how do we configure them in LAN because they are WAN types?


    *(i mean WAN IS CONNECTING LANS so HOW CAN THIS BE?)

    question : look at the * (if * is true , how can ! be?)


    for third : (a simple question
    we wanna build LAN and givin IPs for pcs and
    they will be at same network ,when we have a file sharing
    between two computers in this LAN , why don't we
    connect with cable the two pcs?)


    question : but there is a thing that is "network setup wizard"
    so we can achieve connection with this and without
    direct cables ,why ?


    i have one more question

    - routers vary in the world
    some of them is cheap , some of them s expensive
    and contains more functionality

    so that if i wish setting up a LAN , how do i understand
    whether i use for ex. 2600 router or another?

    Rather than just repeating the question - vary it. We may then understand what you are trying to ask.

    And I repeat my answer - You use special types of routers to enable Frame Relay and ISDN to talk to an Ethernet LAN.
    Or are you asking how you bridge two LANs with a WAN? This is the property of such routers that they can do that.


    The wizard has nothing to do with cables or not cables. It sets up a connection. Also file-sharing is something that will work over almost any connection. It could be WiFi instead of cable.


    Depends on the precise functionality you want, and the reliability. The more you pay the more you get.

    You need to write down the set of facilities you want, and match them against different routers to see which might do the job.

    i couldn't tell ya my questions exactly

    and trying some others(things below may come a bit complexed
    but please read)



    as a sample i have a dsl connection and it is a WAN connectiontype ,however, i can use dsl modem or dsl router in a house(in LAN) although it is a kind of WAN type.

    also i can use ISDN modem in LAN.

    and then when i use these modems i don't configure from the
    beginning , in which time i need this (like we did for routers in labs)


    ................


    i can't imagine the picture that i try to say

    .............




    again coming same question with different style

    if i wanna build a LAN for ex.campus LAN and
    for the first building

    i have PCs and switches then i connect these with cables
    (this looks like easy but i don't think it is )


    if i wanna have internet for this building (first one)
    using dsl with high speed...


    then pass to the second building and do same things
    after doing first and second , lets come to connect
    first with second what should i do here?


    and when does the turn come for a router ? i mean
    these buildings can't have a connection to the outside of the
    campus zone ?
    (with fr or isdn or leased line) when?

    If you don't give us clear questions then it is next to impossible to give clear answers!
    For domestic routers with a clear purpose such as a DSL modem/router most come pre-configured with the most popular settings. All you usualy need to do is put the username and password in. But you *could* go into them and change settings for your situation.
    Depends on the network plan. If both buildings are on the same network, and not too far apart then link the switches in each building.

    Is this last a requirement or a question? If a requirement then you can't have Internet there anyway. If a question then the answer is "Why not?".

    You would need a router if the two buildings were on different networks, or were so far apart that you had to use some other method than Ethernet to connect them.
    I don't understand that last at all. You use those when you need them. There is nothing in your senario that *requires* them.

    And please don't use blocks of colour/bold/italic like that - it makes it *very* hard to disentangle when commenting on bits of postings!
