    question about scsi tech notes,

    i would like to know why the number of devices and the bus width is the same in all cases, i guess is because all devices or available "conections" need their own wire, isn't it?

    and what does SPI-2/3 means, it means i guess improvement but in what aspects and how it affects the SCSI system, this is a topic where all of us need be clearer because this is asked in A+ core and its one of the most complex themes, at leats for me, thanks everyone or your atention

    about RAID, i would like to know why this topic is also for NET+ and also i would like to know if this RAIDS levels can be applied using special software and at least one example please.

    im sorry i am studyng those study guides you have and i want to have everything completely understood, i think that sometimes we have to study something and we can learn it very well but we can really understand the sense of the system seeing in real life, maybe not directly troubleshoting just looking how it works and that...

    something else, when installing a SATA buses have the hard drive to have a special port to allow the conexion? i have built computers with sata support on board but i dont see the connector in the driveso i guess there should be a connector and it would be there only in new devices, also i only can connect one device per cable( desvantage isn't it?)

    one more time thank you vey much for your dedication and time to answer my questions, sometimes a little intensives and boring but need it for me and my own feeling of how i have to know about something icon_idea.gif

    questions again icon_lol.gif icon_lol.gif icon_lol.gif
    after read printer's topic i have this dudes icon_study.gif

    what is Postscript, i mean how it works with the printer and the computer?

    and how really looks a server pirnter? is it a special thing or just a printer attached to one computer and shared for everyone?

    thanks again, im studying hard icon_thumright.gif

    No need to apologize for asking questions, that's what we are here for ;)
    about RAID, i would like to know why this topic is also for NET+ and also i would like to know if this RAIDS levels can be applied using special software and at least one example please.
    It is also part of Server+, I guess you have to ask CompTIA why ;)
    For network+ you need to know that it is 'fault tolerance'. As you can see at the bottom of our Fault Tolerance and Disaster Recovery TechNotes ( www.techexams.net/technotes/networkplus/fault_disast.shtml ) it relates to the Network+ exam objective:
    3.5 Identify the purpose and characteristics of fault tolerance

    For the A+ exam, and Server+ exam however, you need to know the difference between the different types of RAID as well. As you can read at the bottom of our A+ ATA/IDE/EIDE/SATA TechNotes:
    Current related exam objectives for the A+ 2003 exam:

    DOMAIN 1. Installation, Configuration, and Upgrading

    1.6 Identify proper procedures for installing and configuring common IDE devices. Choose the appropriate installation or configuration sequences in given scenarios. Recognize the associated cables.
    Content may include the following:
    - IDE Interface Types
    -- EIDE
    -- ATA/ATAPI
    -- Serial ATA
    -- PIO
    - RAID (0, 1 and 5)
    - Master/Slave/cable select
    - Devices per channel
    - Primary/Secondary
    - Cable orientation/requirements

    RAID5 is often implemented in hardware using special hard disk controllers, also known as array controller. But a typical example of 'software' RAID5 is the stripe set with parity in WindowsNT/2000/2003.
    something else, when installing a SATA buses have the hard drive to have a special port to allow the conexion? i have built computers with sata support on board but i dont see the connector in the driveso i guess there should be a connector and it would be there only in new devices
    yes. And the SATA drives available in stores today are not real (native) SATA drives, although they have a serial ATA connector, there is still a bridge (chip) that convert the parallel data to serial. That is why maximum transfer speed it 'only 150MBps and not 1.5Gbps
    also i only can connect one device per cable( disvantage isn't it?)
    Yes, but they are working on that in the SATA-II extension to SATA 1.0a (www.serialata.org)
    question about scsi tech notes,

    i would like to know why the number of devices and the bus width is the same in all cases, i guess is because all devices or available "conections" need their own wire, isn't it?
    No, the wires are used in parallel. The bus width does not dictate the number of devices. The bus/controller can tell which device is tranferring data because it includes the SCSI ID.

    I have an update planned for the SCSI TechNotes later this month, and will include more details to make it complete for the new 2003 exam objectives.

    I had a TechNote lying around covering some of the objectives related to 'portables' which has been written for TechExams.net by Tracey Rosenblath last summer. It isn't entirely complete, and due to circumstances won't be completed by her either, but figured I should put it online anyway. I will see if I need to add things when I combine all the A+ Core TechNotes in one PDF file.

    I have been going through these CompTIA A+ Core TechNotes: the sub-category of Sockets and CPU's. In fact so far as I have been on the net there has been no site as comphrehensive as these technotes. Can someone tell me why some people are claiming that there are higher processors like Pentium 5-8 in production? Is this true? Or is it a farce?
    I'd be glad to hear from anyone!

    I have a questions regarding your tech notes about SCSI's.
    You wrote that lowest SCSI ID is 0 used for boot drives(disks). For a SCSI Narrow that works out fine 7,6,5,4,3,2,1,0. But with SCSI wide you state that the priority goes like this: 7,6,5,4,3,2,1,0,15,14,13,12,11,10,9,8. Therefore 0 is not the lowest priority but 8 would be. So would 8 then be the lowest priority with SCSI wide?

    in the Printer Technotes on the section called "PRINTER CONNECTIONS"

    you mention both EPP and ECP. I thought that EPP were non-printer paralle port connections, meaning that peripherals that use a parallel port to connect but are not printers, use EPP.

    hi to all
    , this is my first time entering into this website!I must say it is wonderful!im currently studying for 2003 a+ exams.Wondering if anyone has gone through the exams can provide me tips epecially on core hardware....eg ....what are the most questions comptia will expect from candidates like modem,scsi,motherboard, and so on? icon_rolleyes.gif

    Expect anything covered by any good exam guide. Check out the exam objectives at CompTIA. Also, be sure to check out all of the TechNotes and exam aids on Techexams.

    There could be some basic SCSI on this exam, but most advanced SCSI is covered in Server+.

    Best of luck

    Hi i am new to this site. And allready like it alot :)

    Should you maybe update the CPU socket types?
    Since it is a few new ones now like 754,775,939 and 940
    and what about cache on the different cpu`s ?

    - CDROM, used fot atapi CD-ROM drives
    - ARMD, used fo atapi ZIP and LS 120 drives.


    What is "fot" & "fo"

    and "technologie" not "technology" ?


    Thanks

    More praise to Webmaster on these technotes :) :) I've been reading a 1200 page book and have felt so overwhelmed as to how to consolidate the main info & what to put in my flash cards.

    Very nice work. This site is amazing & I will recommend it to all of my computer geek friends :P

    Thanks :)

    'Technologie' is actually the Dutch (as well as many other languages) version of technology. So before I started writing in English, I had written the word 'technologie' thousands of times. It's not like I tried to turn the plural form in singular icon_lol.gif It's been 4 years since I wrote those notes though, I'd probably even write 'Technologie' with an 'y' now...

    Anyway, I'll update it nevertheless because it is indeed a spelling error that shouldn't be in it.

    You know how the author of the TechNote on CPUs and sockets - http://www.techexams.net/technotes/cpu_sockets.shtml - mentioned that you do not have to memorize the pins of the CPUs? I was asked, on the Core Hardware exam, how many pins there were in an xxx processor - xxx pins.

    I joined today and just wanted to thank you for these notes!!!

    I really need to get my A+ cert for work, and I'm determined to take the exam this year... hopefully this quarter.

    I've gone through a book and a few online practice tests, but I need to reall understand a few things before I pay for the exam. So thank you, thank you for these articles. They've refreshed my memory, and I believe I have a better comprehension on a few things.

    It is not working at the moment. Sorry.

    I'll mention it to Webmaster, though you should easily be able to review the material online for the time being. Helps you to memorize that way ;)
