    it seem ARM is better than that of a PC 104. please comment in term of
    application, networking connection, pricing.....speed, open source.

    Is a V6 pontiac engine better than a car or a set of wheels?

    An arm is a processor, PC104 is technically a bus specification but is
    often used for processor boards that use this bus. These processor boards
    might contain an ARM processor or might not. You can't compare them.

    You ask a wild scattering of naive questions, many of which (like this one)
    attempt to compare completely incomparable concepts. This indicates a need
    to read some very basic introductory texts on embedded computing, and/or
    some relevant magazines. Asking silly one line questions and expecting the
    good folk here to wax lyrical and fill your eager mind with their collective
    accumulated wisdom just ain't gonna cut it.

    I suggest you start your self improvement with:

    Circuit Cellar magazine
    Embedded systems programming magazine
    Designing Embedded Hardware by John Catsoulis
    Embedded Microprocessor Systems: Real World Design, Third Edition by Stuart
    Computers as Components by Wayne Wolf

    I need a linux platform to sink my application (project). currently I have
    completed the first stage of testing.

    the current experiment is based on redhat linux and a c program and also
    shell program. I also need ethernat to connect internet.

    q1 so what is "shinking" platform that I can achieve this same kind
    application that I have?
    q2 is parallel I/O is the same parellal port?

    You are still not making any sense, or giving us any sort of information
    that could be of use. I realise that English is not your native language -
    this group is very international, so people are not too bothered about your
    spelling or grammer. But if you want people to give you sensible replies,
    then you will have to put the effort in and write a sensible post. That
    means giving us the information necessary to help you - what is your
    application, what are its requirements, what are your budgets, is this hobby
    or commercial, is it a single system or will it be mass-produced. Tell us a
    little about yourself - you appear to be completely new to embedded systems,
    linux, electronics, and possibly programming in general - are you really up
    to the task you have set yourself? Perhaps you would be better getting hold
    of a couple of books, and coming back when you have read them? Finally, if
    you want help then it is polite to give your name, not just some
    inappropriate pseudonym.

    Mylinux is of the opinion:
    I'll tell you, if you tell me which educational institution you're at, so I
    can avoid any graduates from such a place, and also the name and e-mail
    address of your lecturer for this subject so I can save you the hassle of
    having to submit the answer yourself, by just e-mailing him or her directly.

    I'm sure it'll be easier for you that way.

    To me, this sounds like you're looking for a system to hold an embedded
    Linux app that you have written? This may explain the original question, as
    to whether PC-104 (ie, a PC-104 286/386/486 card on an Biscuit PC-type-thing
    with Ethernet?) is better than ARM (microcontroller) at running Linux. The
    ARM, you are thinking of connecting to a basic PC parallel port for data
    transfer, I'm guessing (based on Q2 below)?

    If this is correct, let us know - I'm sure someone can help (I can't, as I
    have little experience with Linux!)

    As others have said, your questions are too broad to answer without much
    more information about the application. Q1 I can';t understand but Q2's
    answer is probably no, although you 'could' use a parallel port for parallel
    I/O. It just isn't ideal - there are PC104 and other format single-board
    computers which include all the functionality of a PC plus digital I/O
    lines, if this is what you require.

    Keep talking - we need more data to be helpful! :)

    Mylinux is of the opinion:
    Don't like the brain damage?

    Seriously, if you're trying to do this for a job, you're way out of your
    depth, and should do a course or do a bit of reading.

    And if you are doing a course, then you aren't going about your study the
    right way, by a long shot.

    How about a board that is both PC/104 *and* ARM? Arcom makes a PC/104
    board that uses an Intel XScale ARM processor at 400 MHz. At about 1.5
    Watts, it is within many embedded power budgets that are looking for
    that level of CPU processing. It includes a LAN interface and comes
    preinstalled with RedBoot and/or embedded Linux.

    Good luck!
